January 8, 20251 yr Hello, A few weeks ago I got into my server and added a new drive. Everything seemed to go well until I started getting random drives with read or write errors. Most recently, I went several days with no issues and one of my two parity drives got disabled. I stopped the server, checked cables, started back up ran tests and everything seemed fine so I started the parity rebuild of parity drive 2. About 4-5 hours into this (while I was asleep), I had another drive get disabled due to write errors. At this point, it’s still in parity rebuild, and I’m not quite sure what to do. What happens if another drive gets disabled? should I stop parity, shut it down and replace all my cables? what’s the safest route to maintain my data? I have backups of the vital information but it would still be a massive blow to lose data. skynet-diagnostics-20250108-0559.zip
January 8, 20251 yr Community Expert Looks more like a power/connection issue, if it's been happening with multiple disks it may be better to cancel the sync, check all connections, or use a different PSU for example, and then rebuild both, make sure the emulated disk16 is mounting and contents look correct before rebuilding on top.

I’m pretty sure the cables are secure, so I will try a new PSU. Would it be beneficial to rebuild this disk while in maintenance mode?

In Maintenance mode, you won't be able to tell if emulated disk16 is mounting
January 11, 20251 yr Author I replaced the PSU. I was running a 500W 80 plus white rated power supply for 12 SAS drives, 6 fans, and an hba card. I upgraded to an 850w power supply and well, I was able to rebuild the disk / parity and that finished this morning. No errors so far. Will closely monitor over the next few days, but I am wondering if this older power supply was just running at the max constantly and during rebuild when it's hitting everything it was pulling too much juice making the drives to drop off?
