Hi guys, 

 

my server is running without issues in a rack in a Norco 20 disk chassis.

I suddenly had an issue with the UPS and the server was unproperly shutdown after a power failure.

Later, during a Parity-Check, I noticed 1295 sync errors, which stay constant and don't move (if I restart the Parity-Check, without correction´).

I did not correct the parity so far. 

 

Now, what would be the best way to find out, if I just Parity-Check and correct the parity or have to deal with errors on some drive? 

 

I never had any hardware issues and it doesn't look like a cable, etc. issue. The server doesn't move at all.

I have 17 devices (ST8000DM004) in the array and two WDC_WS121KRYZ as parity drives.

 

I have 6.12.10 installed.

A few sync errors after an unclean shutdown are expected, run a correcting check.

But I am not 100% sure. 

Is there a way to have a deeper check to be certain before a kick the parity check with correction?

Of what, that there was an unclean shutdown? You seemed certain:

In any case, and unless you have pre-existing checksums for all your data, or are using btrfs or xfs, not much else you can do other than correct parity.

I am sure that at least one unclean shutdown happened. Also there were never ever sync errors before. This, I am certain. 

I just can not say for certain, that the sync errors were caused by the unclean shutdown... You are probably right though.

 

I don't have checksums, I am now thinking about that. 

 

But, I am using XFS on all of the disks - any ideas as to what and how I can check? 

Anything I can check my data disks that are all XFS formatted? Thanks again.

You should just run a correcting check, the data should be fine, but if they are xfs there's no way to be sure.
