Hello!
I installed linux using LVM logical volumes in /dev/sda, mirror this logical volumes with /dev/sdb
Code:
# pvcreate /dev/sdb2
# vgextend vg_main /dev/sdb2
# lvconvert vg_main/lv_root -m1 -b
# lvconvert vg_main/lv_swap -m1 -b
and removed one of hard drives to check how linux will handle it.
So, linux hands for 2-3 minutes and after it crashed. I'm was suprised-is LVM doesn't support RAID1 mirroring?
Or is it required to make some additional configuration to setup LVM RAID1 mirroring?
