rtho782 Posted March 16, 2021 Share Posted March 16, 2021 I have 1 disk, an older 4tb WD Black, in my array with read errors. There were 3 of these drives in the array, this one and another had previous read errors shown, the other also had reallocated sectors so I swapped it out. The drive in question has no SMART data that would indicate a failure to me. Most of the drives in this array are in the same Netapp DS4243 disk shelf on the same LSI 9201 16e controller, so it's not cabling. The array is currently in a parity rebuild (but has double parity anyway) as I pulled an old 450GB SAS drive from it to put a 12TB SAS drive in it's place. I do have another 12TB SAS drive precleared and ready to add to the array I could swap the 4TB with, but I'm not sure if I'm being overly cautious. The last time I saw read errors, was also in a parity rebuild. Are these read errors recovered errors or unrecovered errors?

The SSDs on the LSI controller are not in the disk shelf, all the HDDs are. tacgnol-core-diagnostics-20210316-0710.zip Quote Link to comment
JorgeB Posted March 16, 2021 Share Posted March 16, 2021 It's logged as a disk problem, you should run an extended SMART test. Quote Link to comment
rtho782 Posted March 17, 2021 Author Share Posted March 17, 2021 I have done so, but it shows no errors. Quote Link to comment
JorgeB Posted March 17, 2021 Share Posted March 17, 2021 Then the disk is fine for, just keep monitoring. Quote Link to comment
