Hi all,
I am looking at using Debian software RAID mirroring and would like to know how it handles system crashes and disk failures.
My only experience with software RAID 1 is with windows 7 inbuilt option. Whenever the system does not shutdown cleanly, upon reboot the disks start resynching and the whole system becomes very sluggish, almost impossible to use. Depending on the size of the disks, this can be quite long (I am guessing this is because it is resynching at the block level).
I was speaking with someone using freeBSD/ZFS and they reckon ZFS does not resynch after a crash and when a disk is replaced it only copies data not each block.
How does linux software RAID 1 handle these two scenarios?
