Power Outage then Unmountable

[rumblefish1]

Hello Everyone,

                      I just had a brown out while setting up a new server. I have been preclearing 23 drives for the last week but had  not gotten as far as setting up a parity drive yet. I have been doing some data transfers to the drives for testing purposes. After the brown out one of the data drives now appears as unmountable Being new at this the only step I took was running the xfs repair with -n, and then the xfs repair. I started the array again and the drive still remains unmountable. I have attached the messages that appeared on the screen after running xfs repair as well as the error I found in the system log. Any help would be appreciated, unfortunately I have some data on that drive that is important for me to recover.

 

Thanks

You need to run xfs_repair on that disk, save the output and post it in case it remains unmontable after running it.

Ran xfs_repair, stopped maintenance mode, then started the array again. The drive still appears unmountable, I have attached screen shot and disk log.

I want to see the output of xfs_repar, not the log.

sorry about that, not familiar with what I should be sending. This is what comes out on the screen after I run xfs_repair with nothing in the options box, and the system log.

You need to use -L

thank you that did the trick.

Is there a chance for data corruption even after running xfs_repair? Will a parity check fix data corruption if it happens like in a scenario like this?

There's a small chance of data corruption, if you were writing to that disk at the time of the unclean shutdown those files have a much greater chance of being corrupt, parity can't help in those situations, only checksums.
