March 26, 20242 yr Hi Guys, Long story short, had some 'thermal management' issues in my 'comms room' that may have started to push some of my older drives closer to EOL. Drive sdj threw a couple of SMART errors so set about replacing that one first with a pre-cleared 4TB drive sdi that was pre-cleared. During rebuild of data drive sde threw 41 read errors which translated to 41 data errors with the rebuild. Last Parity check without errors was 07 Mar 24. See attached diagnostics. sdj still attached to machine and hasn't been touched since removing from the array. Data on that drive is largely expendable. Non-expendable is backed up elsewhere. I have another 4TB waiting to be pre-cleared that is available for either replacement of another drive or adding to the array. What are my next steps before I make this situation worse.....

March 26, 20242 yr Community Expert Logs posted start on Mar 24 12:02:24, so we can't see what happened. Based on SMART sde appears to be failing, you can run an extended SMART test to confirm.
March 26, 20242 yr Author Ok, extended sde SMART test is running. Will post results. Same for sdj, the disc I replaced in the array. Any ideas why there is such a gap in my logs? syslog-previous ends Mar 21 12:30:57. Any place else I can go looking for them? Log seems to be flooded with an nvidia error that I've not seen before!

March 27, 20242 yr Community Expert SMART test passed so the disk is OK for now, keep monitoring, especially these two attributes: ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 1 Raw_Read_Error_Rate POSR-K 200 200 051 - 99 200 Multi_Zone_Error_Rate ---R-- 200 200 000 - 22 If they keep increasing you will likely get more errors, and in that case I would recommend replacing it.
