demian42 Posted July 28, 2020 Posted July 28, 2020 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 Quote
JorgeB Posted July 28, 2020 Posted July 28, 2020 SMART attributes look fine but the errors are reported as an actual disk problem, run an extended SMART test, they can sometimes be intermittent or not even a disk problem. Quote
