Instructions
GNU/Linux VPS
Initiate a server reboot in rescue mode from the Control Panel. Follow our rescue mode guide if necessary.
You can then verify the configuration of the disks:
The partition corresponding to rescue mode (sda1 in this example) is mounted in the directory / and the disk of the VPS is named sdb and should have no mount point.
Example:
If your result looks similar to the output above and the column MOUNTPOINT is empty in the corresponding line (sdb1), you can proceed with the next step.
However, if your result shows that there is a mount point for the VPS partition, it needs to be unmounted first.
Example:
In the example output above, the partition sdb1 is mounted at /mnt/. In order to check the partition, this partition must not be mounted.
To unmount your partition, use the following command:
In this example configuration, the command would be:
Now you can check the partition with "fsck":
If the result is empty, it usually means that the file system is clean. You can also force a check:
Windows VPS
The instructions above do generally not apply to a Windows VPS, because the file system check does not support NTFS. You can however perform a NTFS consistency check on the partitions.
Initiate a server reboot in rescue mode from the Control Panel. Follow our rescue mode guide if necessary.
You can then verify the configuration of the disks:
The partition corresponding to rescue mode (sda1 in this example) is mounted in the directory / and the disk of the VPS is named sdb and should have no mount point.
Example:
If your result looks similar to the output above and the column MOUNTPOINT is empty in the corresponding line, you can proceed with the next step.
However, if your result shows that there is a mount point for the VPS partition, it needs to be unmounted first.
Example:
In the example output above, the partition concerned sdb2 is mounted at /mnt/. In order to check the partition, this partition must not be mounted.
To unmount your partition, use the following command:
In this example configuration, the command would be:
The following command checks the partition for consistency and tries to resolve errors if any are found:
In this example configuration, the command would be:
