Previously I won't have any parity check sync errors for months. But lately, after I replaced 1 x HDD (faulty) and 1 x 8087 cable (replaced cable due to UDMA CRC error count). Sync errors have been popping up. Is that a cause for concern ?

 

For example, I did a parity check on :

24-Jan-2022, there were 766 sync errors

31-Jan-2022, there were 272 sync errors

01-Feb-2022, there were 128 sync errors

 

I'm in the progress of my 4th parity checks, and there are still 128 sync errors

 

Can experts please kindly advise on what I should do ? 

 

Attached is the diagnostics ZIP for your reference.

 

By the way, in the event that I need to replace a current HDD (8/10TB) with a higher capacity HDD (14TB), what's the correct procedure ?

Is it use new 14TB HDD to replace either 1 of the parity HDD, then use the replaced parity HDD as normal data HDD

Connection problems on disk 4, check connections, both ends, SATA and power, including splitters.

 

Why do you have 50G docker.img? 20G is often more than enough.

 

Even more, why 100G libvirt? I don't think anyone has ever needed more than default 1G for that.

At which log/area did U find that it is disk4 that is give the issue ? so that I may learn how to troubleshoot the issue in the future

 

For issue 2 & 3, how do I fix those "oversized" issue ? Do I have to recreate ?

Not a pro on drive connection issues, but your syslog has tons of this :

and earlier in syslog you can see what disk that corresponds to:

Jan 30 21:23:54 Tower kernel: ata4.00: ATA-9: ST8000AS0002-1NA17Z,             Z840YTGS, RT17, max UDMA/133

 

Thanks to all.

 

The issue has been resolved. Re-do both the SATA and power cables
