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.
