2/3 drives showing as unmountable after power outage.

Featured Replies

I'm in need of some big help here...

I had a power outage that caused 2 of my 3 drives to show as "unmountable" after a reboot. I'm not sure what next steps to take to insure I don't loose data.

 

I have sense ordered a UPS :(

I'm getting a similar output from drive2

I am on 6.9.2. I've heard others say to upgrade to 6.1.0 but wasn't sure.

Try upgrading to v6.12 since it includes newer xfsprogs and try again, if it still fails post new diags after running xfs_repair.

Never mind, reran and we're back.
