January 9, 20251 yr My unraid server is doing a parity check due to an unclean shutdown from power loss. One drive is reporting 6400 “raw read errors” and Reallocate sector count is 154. It’s still in middle of the parity check that’s not yet completed (47% complete) Should I let the parity check complete or just stop it and remove the drive and rebuild the array? tower-diagnostics-20250108-1914.zip Edited January 9, 20251 yr by tmchow Added diagnostics
January 9, 20251 yr Author A few hours later I got message that disk is now disabled and the parity check is continuing. I’m attaching another set of diagnostics. tower-diagnostics-20250108-2302.zip
January 9, 20251 yr Author 9 hours ago, JorgeB said: That disk should be replaced. Sorry no i understand that. I'm asking whether i need to wait for parity check to be finished to do that. I believe the answer is yes, so parity is properly calculated but i'm not sure.
January 9, 20251 yr Solution You can see if it can finish, but parity won't be able to correct any sectors where that disk has read errors, but if there are sync errors because of the unclean shutdown, and they don't coincide with bad sectors on that disk, it can correct those.
