January 6, 20251 yr Hello, I have my parity scheduled to run quarterly. My parity check kicked off this morning, and a couple of hours in to it I received a notice that Disk 5 has been disabled due to read errors and has been assigned a new drive letter in unRAID. The data appears to be in tact, and I am able to rebuild the drive from existing parity, but the drive letter being switched mid parity check is concerning Normally my server works perfectly fine, and I do not have read errors 7 of my drives are Seagate Exos 16TB drives. 1 of the drives is a Seagate Ironwolf Pro The drive that is showing errors is an Exos I have recently replaced my SAS to SATA breakout cables and the power cables on all the drives. I have posted my diagnostics. If someone can please tell me what is going on I would really appreciate it Update: I just tried a data reconstruction on the drive and now I have 2 drives in error states. Uploading another diagnostics file No such file or directory (2): tagged device ST16000NM000E-3NV101_ZX25HQ5B was (sdh) is now (sdj) diagnostics.zip new diagnostics.zip Edited January 6, 20251 yr by loyalsnoopdoge
January 7, 20251 yr Community Expert Solution Disks are dropping offline, this is typically a power/connection issue.

January 7, 20251 yr Community Expert Doesn't look related, since the issues didn't happen after a spin up.

The SAS to SATA breakout cables and SATA power cables are all relatively new. Is there anything else that could be causing an issue like this? Is it possible that the drives spinning up over the few months in between parity checks could partially loosen the cables?

Don't think so, but cables can go bad or start having connection issues without an apparent reason, seen it happen multiple times.
