Sync Errors Remain, Yelp!

[leeknight1981]

i Guy's as usual when i am away i have issue's lol Never when i am home with he server i think she likes to punish me for being away XD 

 

So i ran a Non Correcting Parity Scan and it retuned about 2500 ish sync errors So i shut the server down and ra an Error Correcting Scan and that returned the same value XD 

 

So i shut the server down left it over night and its 50% threw another parity scan and showing 336 errors so far. 

Ill attach logs so peoples can have a look for me as i cba do all that digging on an ipad screen, If someone can give me an idea of what or where to look Which disk etc from the logs, Server hasn't moved its a R720XD with all drives fixed in drive trays. 

TIA

I only see a non correcting check in the diags, run two correcting checks without rebooting, then post new diags.

[leeknight1981]

Ok so i understand you! You want me to run another Correcting without rebooting? I have ran 1 non correcting and then 2 correcting and the 2 correcting have shown 2 different sync errors. is it safe to run 4 in a week lol 

 

 

Many Thanks

Two correcting checks, one after the other, without rebooting.

Defo rebooted between 2nd and 3rd i shall stop everything and shut the 720 down now via idrac and then re boot it and start another scan, Then come back and let you know in a day or two Lol  

[leeknight1981]

Iv ran 4 in the past week there all above each giving a different amount of errors  with re booting without re booting. So not really sure what to do next!

You posted one log showing a non correcting check, I asked for two consecutive correcting checks to compare the errros, you posted only one, I'm not asking again, it's up to you if you want to continue.

[leeknight1981]

i am just concerned about running so many parity scans in a week iv done 4 already is it safe? seems a lot of stress on the drives, ok ill start another scan now

It's fine, if any disk fails now it would fail soon anyway.

[leeknight1981]

Sorry didn’t mean to be short with you there’s years of my life on there like 10 years and currently it’s my only copy due to COVID. Where or what am I looking for in the logs? I’d like to be able to understand instead of trying to sort it during work and hectic life. I started another at 1950 so I guess have to wait another 24 ish hours and prey a drive doesn’t fail but hey ho of it fails I’ll swap it with a 12 

 

cheers

I just want to see if the errors are in the same sectors or not, if it starts finding errors you don't need to let it finish since only the first ones will be logged, e.g., previous one:

 

Mar 17 11:29:51 R720XD kernel: md: recovery thread: check P Q ...
...
Mar 18 00:33:05 R720XD kernel: md: recovery thread: stopped logging

 

It stopped logging after 13 hours or so, you can stop the current one when it also stops logging (assuming errors are found), then post diags.

Ok thats returned 0 sync errors So is the way forward if i run it every 3 months and it shows sync errors Do i simply run it again error correcting with no reboot? Was there actual errors and now showing 0 as its corrected then or did it think they was errors and is now happy there isn't. 

Many Thanks for your help with this i just do not Get the time to sort stuff out research stuff i am always working and rarely at home with the server and when i am at home its family time XD

OK, now wait for the next scheduled check and see how that one goes, and make sure no unclean shutdowns in between, as a few errors after one are normal.
