April 30, 20224 yr So I had one disk show read errors during the monthly parity check. I'm guessing read errors are a bit different from write errors in that UnRaid doesn't disable the drive? What are my next steps here? Just move the files off this disk and replace the disk? It's the oldest one, going at 10 yrs, I think. So I have no problem getting rid of it. Diags below Unraid 6.9.2 I have a bunch of these in syslog: Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949051960 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949051968 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949051976 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949051984 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949051992 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949052000 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949052008 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949052016 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949052024 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949052032 Apr 28 22:32:51 Tower kernel: md: disk12 read error, sector=2949052040 About Disk 12: Apr 19 07:39:52 Rigel kernel: xfs filesystem being mounted at /mnt/disk12 supports timestamps until 2038 (0x7fffffff) Apr 19 07:39:52 Rigel emhttpd: shcmd (6511): xfs_growfs /mnt/disk12 Apr 19 07:39:52 Rigel root: meta-data=/dev/mapper/md12 isize=512 agcount=4, agsize=122094532 blks Apr 19 07:39:52 Rigel root: = sectsz=512 attr=2, projid32bit=1 Apr 19 07:39:52 Rigel root: = crc=1 finobt=1, sparse=0, rmapbt=0 Apr 19 07:39:52 Rigel root: = reflink=0 Apr 19 07:39:52 Rigel root: data = bsize=4096 blocks=488378126, imaxpct=5 Apr 19 07:39:52 Rigel root: = sunit=0 swidth=0 blks Apr 19 07:39:52 Rigel root: naming =version 2 bsize=4096 ascii-ci=0, ftype=1 Apr 19 07:39:52 Rigel root: log =internal log bsize=4096 blocks=238465, version=2 Apr 19 07:39:52 Rigel root: = sectsz=512 sunit=0 blks, lazy-count=1 Apr 19 07:39:52 Rigel root: realtime =none extsz=4096 blocks=0, rtextents=0 WDC_WD20EARS-00MVWB0_WD-WCAZA5944835-20220428-2238 disk12 (sdo).txt
April 30, 20224 yr Community Expert Do you have your monthly parity check as correcting or non-correcting?

Attached - this was before the extended SMART, as soon as I got the error. I'll be running an extended now. 5 hours ago, trurl said: "Yes" is not the correct answer to a multiple choice question.

May 1, 20224 yr Community Expert It's logged as a disk issue, and SMART shows some issues, wait for the extended test result.

May 2, 20224 yr Community Expert These can be intermittent, since the test passed disk is OK for now, but you should keep monitoring, especially these attributes: 1 Raw_Read_Error_Rate POSR-K 200 200 051 - 0 200 Multi_Zone_Error_Rate ---R-- 200 200 000 - 126 If they climb you'll likely get more read errors.

Thanks will do!
