Anybody has experience with linux Raid5 and power outages?, i currently have two 250GB disks in a RAID1 array in my main workstation. When there's any power outage the array is rebuilt but given it's a mirror it's not a major issue.
Now i would like to add 4 500GB disks in a secondary array with raid5 but i'm afraid i would lose the array if there's any outage (have to mention a UPS in my letter to Santa....)
Anybody knows if the raid5 (md) would survive this scenario?
It should.
It might, actually: no filesystem likes a power outage, and no raid will protect you from that.
