Although a robust and redundant storage is recommended,
|
|
it can be very helpful to monitor the health of your local disks.
|
|
|
|
Starting with {pve} 4.3, the package smartmontools footnote:[smartmontools homepage https://www.smartmontools.org]
|
|
is installed and required. This is a set of tools to monitor and control
|
|
the S.M.A.R.T. system for local hard disks.
|
|
|
|
You can get the status of a disk by issuing the following command:
|
|
----
|
|
# smartctl -a /dev/sdX
|
|
----
|
|
|
|
where /dev/sdX is the path to one of your local disks.
|
|
|
|
If the output says:
|
|
|
|
----
|
|
SMART support is: Disabled
|
|
----
|
|
|
|
you can enable it with the command:
|
|
|
|
----
|
|
# smartctl -s on /dev/sdX
|
|
----
|
|
|
|
For more information on how to use smartctl, please see `man smartctl`.
|
|
|
|
By default, smartmontools daemon smartd is active and enabled, and scans
|
|
the disks under /dev/sdX and /dev/hdX every 30 minutes for errors and warnings, and sends an
|
|
e-mail to root if it detects a problem.
|
|
|
|
For more information about how to configure smartd, please see `man smartd` and
|
|
`man smartd.conf`.
|
|
|
|
If you use your hard disks with a hardware raid controller, there are most likely tools
|
|
to monitor the disks in the raid array and the array itself. For more information about this,
|
|
please refer to the vendor of your raid controller.
