39: \fB/usr/local/etc/smartd.conf\fP is the configuration file for the \fBsmartd\fP
1.1.1.3 ! misho 40: daemon.
1.1 misho 41:
42: If the configuration file \fB/usr/local/etc/smartd.conf\fP is present,
43: \fBsmartd\fP reads it at startup, before \fBfork\fP(2)ing into the
44: background. If \fBsmartd\fP subsequently receives a \fBHUP\fP signal,
45: it will then re-read the configuration file. If \fBsmartd\fP is
46: running in debug mode, then an \fBINT\fP signal will also make it
47: re-read the configuration file. This signal can be generated by typing
48: \fB\<CONTROL-C\>\fP in the terminal window where \fBsmartd\fP is
49: running.
50:
51: In the absence of a configuration file
1.1.1.3 ! misho 52: \fBsmartd\fP will try to open all available devices
! 53: (see \fBsmartd\fP(8) man page).
! 54: A configuration file with a single line \fB\'DEVICESCAN \-a'\fP
! 55: would have the same effect.
1.1 misho 56:
57: This can be annoying if you have an ATA or SCSI device that hangs or
58: misbehaves when receiving SMART commands. Even if this causes no
1.1.1.3 ! misho 59: problems, you may be annoyed by the string of error log messages about devices
! 60: that can\'t be opened.
1.1 misho 61:
62: One can avoid this problem, and gain more control over the types of
63: events monitored by
64: \fBsmartd\fP,
65: by using the configuration file
66: .B /usr/local/etc/smartd.conf.
67: This file contains a list of devices to monitor, with one device per
68: line. An example file is included with the
69: .B smartmontools
70: distribution. You will find this sample configuration file in
71: \fB/usr/local/share/doc/smartmontools/\fP. For security, the configuration file
72: should not be writable by anyone but root. The syntax of the file is as
73: follows:
74: .IP \(bu 4
75: There should be one device listed per line, although you may have
76: lines that are entirely comments or white space.
77: .IP \(bu 4
78: Any text following a hash sign \'#\' and up to the end of the line is
79: taken to be a comment, and ignored.
80: .IP \(bu 4
81: Lines may be continued by using a backslash \'\e\' as the last
82: non-whitespace or non-comment item on a line.
83: .IP \(bu 4
84: Note: a line whose first character is a hash sign \'#\' is treated as
85: a white-space blank line, \fBnot\fP as a non-existent line, and will
86: \fBend\fP a continuation line.

489: [ATA only] This \'nocheck\' Directive is used to prevent a disk from
490: being spun-up when it is periodically polled by \fBsmartd\fP.
491:
492: ATA disks have five different power states. In order of increasing
493: power consumption they are: \'OFF\', \'SLEEP\', \'STANDBY\', \'IDLE\',
494: and \'ACTIVE\'. Typically in the OFF, SLEEP, and STANDBY modes the
495: disk\'s platters are not spinning. But usually, in response to SMART
496: commands issued by \fBsmartd\fP, the disk platters are spun up. So if
1.1.1.3 ! misho 497: this option is not used, then a disk which is in a low-power mode may
! 498: be spun up and put into a higher-power mode when it is periodically
1.1 misho 499: polled by \fBsmartd\fP.
500:
501: Note that if the disk is in SLEEP mode when \fBsmartd\fP is started,
502: then it won't respond to \fBsmartd\fP commands, and so the disk won't
503: be registered as a device for \fBsmartd\fP to monitor. If a disk is in
1.1.1.3 ! misho 504: any other low-power mode, then the commands issued by \fBsmartd\fP to
! 505: register the disk will probably cause it to spin-up.
1.1 misho 506:
507: The \'\fB\-n\fP\' (nocheck) Directive specifies if \fBsmartd\fP\'s
508: periodic checks should still be carried out when the device is in a
1.1.1.3 ! misho 509: low-power mode. It may be used to prevent a disk from being spun-up
1.1 misho 510: by periodic \fBsmartd\fP polling. The allowed values of POWERMODE
511: are:
512:
513: .I never

1.1.1.3 ! misho 515: mode. This may cause a disk which is spun-down to be spun-up when

518:
519: .I sleep
520: \- check the device unless it is in SLEEP mode.
521:
522: .I standby
523: \- check the device unless it is in SLEEP or STANDBY mode. In
524: these modes most disks are not spinning, so if you want to prevent
525: a laptop disk from spinning up each time that \fBsmartd\fP polls,
526: this is probably what you want.
527:
528: .I idle
529: \- check the device unless it is in SLEEP, STANDBY or IDLE mode.
530: In the IDLE state, most disks are still spinning, so this is probably
531: not what you want.
532:
533: Maximum number of skipped checks (in a row) can be specified by
534: appending positive number \',N\' to POWERMODE (like \'\-n standby,15\').
535: After N checks are skipped in a row, powermode is ignored and the
536: check is performed anyway.
537:
538: When a periodic test is skipped, \fBsmartd\fP normally writes an
539: informal log message. The message can be suppressed by appending
540: the option \',q\' to POWERMODE (like \'\-n standby,q\').

930:
931: .I once

942: then a two-day interval, then a four-day interval, and so on for each
943: type of disk problem detected. Each interval is twice as long as the
944: previous interval.

1276: .B \-C ID[+]
1277: [ATA only] Report if the current number of pending sectors is
1278: non-zero. Here \fBID\fP is the id number of the Attribute whose raw
1279: value is the Current Pending Sector count. The allowed range of
1280: \fBID\fP is 0 to 255 inclusive. To turn off this reporting, use
1281: ID\ =\ 0. If the \fB\-C ID\fP option is not given, then it defaults to
1282: \fB\-C 197\fP (since Attribute 197 is generally used to monitor
1283: pending sectors). If the name of this Attribute is changed by a
1284: \'\-v 197,FORMAT,NAME\' directive, the default is changed to
1285: \fB\-C 0\fP.
1286:
1287: If \'+\' is specified, a report is only printed if the number of sectors
1288: has increased between two check cycles. Some disks do not reset this
1289: attribute when a bad sector is reallocated.
1290: See also \'\-v 197,increasing\' below.
1291:
1292: The warning email counter is reset if the number of pending sectors
1293: dropped to 0. This typically happens when all pending sectors have
1294: been reallocated or could be read again.
1295:
1296: A pending sector is a disk sector (containing 512 bytes of your data)
1297: which the device would like to mark as ``bad" and reallocate.
1298: Typically this is because your computer tried to read that sector, and
1299: the read failed because the data on it has been corrupted and has
1300: inconsistent Error Checking and Correction (ECC) codes. This is
1301: important to know, because it means that there is some unreadable data
1302: on the disk. The problem of figuring out what file this data belongs
1303: to is operating system and file system specific. You can typically
1304: force the sector to reallocate by writing to it (translation: make the
1305: device substitute a spare good sector for the bad one) but at the
1306: price of losing the 512 bytes of data stored there.
1307: .TP
1308: .B \-U ID[+]
1309: [ATA only] Report if the number of offline uncorrectable sectors is
1310: non-zero. Here \fBID\fP is the id number of the Attribute whose raw
1311: value is the Offline Uncorrectable Sector count. The allowed range of
1312: \fBID\fP is 0 to 255 inclusive. To turn off this reporting, use
1313: ID\ =\ 0. If the \fB\-U ID\fP option is not given, then it defaults to
1314: \fB\-U 198\fP (since Attribute 198 is generally used to monitor
1315: offline uncorrectable sectors). If the name of this Attribute is changed
1316: by a \'\-v 198,FORMAT,NAME\' (except \'\-v 198,FORMAT,Offline_Scan_UNC_SectCt\'),
1317: directive, the default is changed to \fB\-U 0\fP.
1318:
1319: If \'+\' is specified, a report is only printed if the number of sectors
1320: has increased since the last check cycle. Some disks do not reset this
1321: attribute when a bad sector is reallocated.
1322: See also \'\-v 198,increasing\' below.
1323:
1324: The warning email counter is reset if the number of offline uncorrectable
1325: sectors dropped to 0. This typically happens when all offline uncorrectable
1326: sectors have been reallocated or could be read again.
1327:
1328: An offline uncorrectable sector is a disk sector which was not
1.1.1.3 ! misho 1329: readable during an off-line scan or a self-test. This is important
1.1 misho 1330: to know, because if you have data stored in this disk sector, and you
1331: need to read it, the read will fail. Please see the previous \'\-C\'
1332: option for more details.
1333: .TP
1334: .B \-W DIFF[,INFO[,CRIT]]
1335: Report if the current temperature had changed by at least \fBDIFF\fP
1336: degrees since last report, or if new min or max temperature is detected.
1337: Report or Warn if the temperature is greater or equal than one of
1338: \fBINFO\fP or \fBCRIT\fP degrees Celsius.
1339: If the limit \fBCRIT\fP is reached, a message with loglevel
1340: \fB\'LOG_CRIT\'\fP will be logged to syslog and a warning email
1.1.1.3 ! misho 1341: will be send if \'\-m\' is specified. If only the limit \fBINFO\fP is
1.1 misho 1342: reached, a message with loglevel \fB\'LOG_INFO\'\fP will be logged.
1343:
1344: The warning email counter is reset if the temperature dropped below
1345: \fBINFO\fP or \fBCRIT\fP-5 if \fBINFO\fP is not specified.
1346:
1347: If this directive is used in conjunction with state persistence
1348: (\'\-s\' option), the min and max temperature values are preserved
1349: across boot cycles. The minimum temperature value is not updated
1350: during the first 30 minutes after startup.
1351:
1352: To disable any of the 3 reports, set the corresponding limit to 0.
1353: Trailing zero arguments may be omitted. By default, all temperature

1.1 misho 1381:
1382: .I none
1383: \- Assume that the device firmware obeys the ATA specifications. This
1384: is the default, unless the device has presets for \'\-F\' in the

1.1 misho 1396: Enabling this option tells \fBsmartd\fP to evaluate these quantities
1.1.1.3 ! misho 1397: in byte-reversed order. Some signs that your disk needs this option
! 1398: are (1) no self-test log printed, even though you have run self-tests;

1429: if no other \'-C\' directive is specified.
1430:
1431: .I 198,increasing
1432: \- Raw Attribute number 198 (Offline Uncorrectable Sector Count) is not

1435: .TP
1436: .B \-P TYPE
1437: [ATA only] Specifies whether \fBsmartd\fP should use any preset options

1442: \- use any presets that are available for this drive. This is the default.
1443:
1444: .I ignore

1460: to check the SMART health status,
1461: .B \'\-f\'
1462: to report failures of Usage (rather than Prefail) Attributes,
1463: .B \'\-t\'
1464: to track changes in both Prefailure and Usage Attributes,
1465: .B \'\-l\ error\'
1466: to report increases in the number of ATA errors,
1467: .B \'\-l\ selftest\'
1468: to report increases in the number of Self-Test Log errors,

1472: to report nonzero values of the current pending sector count, and
1473: .B \'\-U 198\'
1474: to report nonzero values of the offline pending sector count.
1475:
1476: Note that \-a is the default for ATA devices. If none of these other

1486: .PP
1487: If you are not sure which Directives to use, I suggest experimenting
1488: for a few minutes with
1489: .B smartctl
1490: to see what SMART functionality your disk(s) support(s). If you do
1491: not like voluminous syslog messages, a good choice of
1492: \fBsmartd\fP
1493: configuration file Directives might be:
1494: .nf
1495: .B \-H \-l\ selftest \-l\ error \-f.

1500: .TP
1501: .B ADDITIONAL DETAILS ABOUT DEVICESCAN
1502: If a non-comment entry in the configuration file is the text
1503: string \fBDEVICESCAN\fP in capital letters, then \fBsmartd\fP will
1504: ignore any remaining lines in the configuration file, and will scan
1.1.1.3 ! misho 1505: for devices (see also \fBsmartd\fP(8) man page).
1.1 misho 1506:
1507: If \fBDEVICESCAN\fP is not followed by any Directives, then smartd
1508: will scan for both ATA and SCSI devices, and will monitor all possible
1509: SMART properties of any devices that are found.
1510:
1511: \fBDEVICESCAN\fP may optionally be followed by any valid Directives,
1512: which will be applied to all devices that are found in the scan. For
1513: example
1514: .nf
1515: .B DEVICESCAN -m root@example.com
1516: .fi
1517: will scan for all devices, and then monitor them. It will send one
1518: email warning per device for any problems that are found.
1519: .nf
1520: .B DEVICESCAN -d ata -m root@example.com
1521: .fi
1522: will do the same, but restricts the scan to ATA devices only.
1523: .nf
1524: .B DEVICESCAN -H -d ata -m root@example.com
1525: .fi
1526: will do the same, but only monitors the SMART health status of the
1527: devices, (rather than the default \-a, which monitors all SMART
1528: properties).
1529:
1.1.1.3 ! misho 1530: [NEW EXPERIMENTAL SMARTD FEATURE]
! 1531: Configuration entries for specific devices may precede the \fBDEVICESCAN\fP entry.

! 1535: .B /dev/sda -s S/../.././02
! 1536: .B /dev/sdc -d ignore
! 1537: .B DEVICESCAN -s L/../.././02
! 1538: .fi
! 1539: will scan for all devices except /dev/sda and /dev/sdc, monitor them, and run a long
! 1540: test between 2-3am every morning. Device /dev/sda will also be monitored, but
! 1541: only a short test will be run. Device /dev/sdc will be ignored.

1545: .B EXAMPLES OF SHELL SCRIPTS FOR \'\-M exec\'
1546: These are two examples of shell scripts that can be used with the \'\-M
1547: exec PATH\' Directive described previously. The paths to these scripts
1548: and similar executables is the PATH argument to the \'\-M exec PATH\'
1549: Directive.
1550:
1551: Example 1: This script is for use with \'\-m ADDRESS -M exec PATH\'. It appends
1552: the output of
1553: .B smartctl -a
1554: to the output of the smartd email warning message and sends it to ADDRESS.

1569: .fi
1570:
1571: Example 2: This script is for use with \'\-m <nomailer> \-M exec
1572: PATH\'. It warns all users about a disk problem, waits 30 seconds, and
1573: then powers down the machine.
1574:

1590: .fi
1591:
1592: Some example scripts are distributed with the smartmontools package,
1593: in /usr/local/share/doc/smartmontools/examplescripts/.
1594:
1595: Please note that these scripts typically run as root, so any files
1596: that they read/write should not be writable by ordinary users or
1597: reside in directories like /tmp that are writable by ordinary users
1598: and may expose your system to symlink attacks.
1599:
1600: As previously described, if the scripts write to STDOUT or STDERR,
1601: this is interpreted as indicating that there was an internal error
1602: within the script, and a snippet of STDOUT/STDERR is logged to SYSLOG.
1603: The remainder is flushed.
