hi all,
In the past I used software RAID-1 and monitored /proc/mdstat to make sure things were ok in the array. I am starting to play with /dev/mapper and was wondering how I monitor this for a disk going bad.
For disk errors use smartmon.
If there is an error in the device mapper you will now about it right away as the system will fail.
There are LVM configuration backups kept, make sure they're kept in /boot.
