There's something seriously wrong there. I wouldn't worry about taking the raid offline, because it looks like there's a major corruption problem so the data on it is extremely suspect!
Now I have everything to determine _exactly_ whether it's safe to repair it or not. For now it looks like I have luck. The inconsistencies came from a power failure some weeks ago and I can make it consistent again without serious problems and further downtime.
RAID 1 has that problem.
3ware raid cards always degrade the mirror in the event of an uncontrolled shutdown.
The first drive of the pair is made the online drive, and the second drive is resync'ed to it.
I don't know how mdraid handles it.
Should do the same unless you use intent log, in which case it needs to resync only small part. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
