I've tried searching for this answer, but haven't found anything elegant.
I have numerous servers in a colo that is in another state. I need to find a way to check that the servers have RAID-1 on them, so that I can determine if they were setup correctly by my colo.
df -h shows: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 442G 1.5G 418G 1% / /dev/sda1 99M 19M 75M 20% /boot tmpfs 4.0G 0 4.0G 0% /dev/shm
however as CentOS uses LVM by default, this doesn't indicate if a RAID-1 is present.
it is supposed to be a software raid, so I'm pretty sure there should be a way to check.
