ODA V1 - cat /proc/mdstat -- When was the last time you checked the health of your system disks
Update: 4/19/2017
The frequency of System / Boot disk replacement continues with the very popular but now aging V1 ODA
Please run cat /proc/mdstat on each node of your V1 to confirm that both system disks are healthy monthly as a _requirement_
I have recently seen a few user's create SRs based on failed system disks. This is inevitable.
However, a few users have never checked the health of the system disks.
This led to having to rebuild one of the two nodes once both system disks failed!
EXAMPLE - Good
cat /proc/mdstat
Personalities : [raid1]
