Hi,
we have a TrueNAS-13.0-U4 System on some Supermicro Hardware with
a AMD EPYC 7232P , 128GB EEC RAM and
12 TOSHIBA MG07ACA1 SATA HDDs in 3 RAIDZ1
It is mainly used as temporary storage for not really important data (mainly images and stuff that can be recreated, additionally there is a backup) which is why I am still somewhat relaxed about this.
However: Random disks keep Receiving the FAULTED state with the message "too many errors".
The disks themselves seem to look fine. SMART does not detect anything and even Long SMART tests that I did in the beginning came back clean.
By now I go in about once every two weeks and do the following on the faulted disk:
Then it resilvers for about 5 seconds (as I said it is mostly lightly used) and everything is fine again for a few days.
Any ideas what might be causing this behavior? Is there some System bottleneck that fails getting the data to the disk at some load peaks?
Is there any logging that can tell me when these write/read error occurred?
