Disk Read Errors


Recommended Posts

Hi.  I have been using UnRaid for about 8 years but recently migrated to rack mount system, added drives, converting to xfs, running VM's for Pfsense - so, much more active in the last 6 months.  I am using unbalance to move files off of Disk 2 for conversion to XFS and I just now had 30 read errors on Disk 2.  I got the warning - and I am very worried, but it seems like unraid should be more worried.  I mean the warning is the same as when the cache is filling up or a drive is near capacity - it seems like this warning should be more "red" than the other warnings - but not really my issue.  My issue is How do I know if Disk 2 is toast ?

 

SMART for disk 2 shows very high numbers across the board.  The numbers for two new 10TB IronWolf Pro drives are much lower - for example

                  disk 2           parity (new)       disk 6 (new)

Att # 1        200                 078                 072

Att # 5       200                 100                 100vishnu-diagnostics-20200728-1159.zip
