1 | Disk Health Monitoring |
| 2 | ---------------------- | |

| 5 | Altough a robust and redundant storage is recommended, | |
| 6 | it can be very helpful to monitor the health of your local disks. | |
| 7 | ||
| 8 | Starting with {pve} 4.3, the package smartmontools footnote:[smartmontools homepage https://www.smartmontools.org] | |
| 9 | is installed and required. This is a set of tools to monitor and control | |
| 10 | the S.M.A.R.T. system for local hard disks. | |
| 11 | ||
| 12 | You can get the status of a disk by issuing the following command: | |
| 13 | ---- | |
| 14 | # smartctl -a /dev/sdX | |
| 15 | ---- | |
| 16 | ||
| 17 | where /dev/sdX is the path to one of your local disks. | |
| 18 | ||
| 19 | If the output says: | |
| 20 | ||
| 21 | ---- | |
| 22 | SMART support is: Disabled | |
| 23 | ---- | |
| 24 | ||
| 25 | you can enable it with the command: | |
| 26 | ||
| 27 | ---- | |
| 28 | # smartctl -s on /dev/sdX | |
| 29 | ---- | |
| 30 | ||
| 31 | For more information on how to use smartctl, please see `man smartctl`. | |
| 32 | ||
| 33 | By default, smartmontools daemon smartd is active and enabled, and scans | |
| 34 | the disks under /dev/sdX and /dev/hdX every 30 minutes for errors and warnings, and sends an | |
| 35 | e-mail to root if it detects a problem. | |
| 36 | ||
| 37 | For more information about how to configure smartd, please see `man smartd` and | |
| 38 | `man smartd.conf`. | |
| 39 | ||
| 40 | If you use your hard disks with a hardware raid controller, there are most likely tools | |
| 41 | to monitor the disks in the raid array and the array itself. For more information about this, | |
| 42 | please refer to the vendor of your raid controller. |
