May 26, 20251 yr Tried to replace 12TB drive 15 with precleared 20TB drive.Data-rebuild began okay.Hours later, drive 11 starts throwing read errors and eventually gets auto-removed from the array, contents emulated.I paused the data-rebuild.I went to the now-unassigned drive 11 (disk sdaa under unassigned devices) and ran its extended Smart report.Took over a day, but cleared with no error.I pulled diagnostics at this time. (attached omni-diagnostics-20250526-1437)I read that in cases like this, it (might) be power and connectors.I stopped the array.I opened the case and checked drive SAS and power connectors.I hot-swapped an unassigned hot spare with the original 12TB drive that was going to be replaced.In the array config in Main, I replaced the precleared 20TB drive with the original 12TB in slot 15.I took a screenshot to confirm drive assignments.In Tools, I set a new config, preserving all assignments.I confirmed drive positions with the screenshot.I marked parity as valid.I started the array in maintenance mode.I pulled another set of diagnostics. (attached omni-diagnostics-20250526-1521)What should I do next to make sure that drive 11 is good? Should I run a parity-sync without writing corrections?omni-diagnostics-20250526-1437.zip omni-diagnostics-20250526-1521.zip Edited May 28, 20251 yr by elecgnosis
May 27, 20251 yr Community Expert Since you already did a new config, the best option now is likely running a correct parity check, but the syslog doesn't have the current info, reboot and post new diags after array start.
May 28, 20251 yr Community Expert Syslog is full of spam due to SMB errors, delete everything from SMB extras, reboot and post new diags after array start.
May 28, 20251 yr Author I started in maintenance mode, do you mean for me to start the array normally?
May 28, 20251 yr Community Expert Solution Everything looks good for now, run a correcting parity check.P.S. I would consider adding a 2nd parity with so many disks.
May 28, 20251 yr Author Thanks again, and I just might.Should I run the correcting parity check in maintenance mode? Does it matter at this point?
