Keep an Eye on Your RAID Status

Our customers frequently order systems with two hard drives to hold a RAID 1 volume mirroring the OS filesystems. This is done with Linux software RAID, and it’s important to periodically check the health of the drives. To do this, run cat /proc/mdstat.

If all volume members are working properly, you should see [UU]. For more detail, you can run mdstat -Q –detail /dev/md0, substituting /dev/md0 where appropriate. You should see State: clean in normal operations. Contact Advanced Clustering Support for assistance if you ever find problems with your RAID volumes, or for further information about Linux software RAID.

Use our Breakin stress test and diagnostics tool to pinpoint hardware issues and component failures.
