March 6, 20251 yr The parity process runs for hours and almost completes, but then the server suddenly becomes unreachable. When I restart and log back in, it shows that the parity was canceled just 11 seconds after starting, which doesn’t make sense given how long it actually runs. I’ve already run a RAM check, and everything seems fine. There is a UDMA CRC error on the parity drive, but it’s not increasing.

March 6, 20251 yr Community Expert If it completed, there's not much to see, or were there any issues/errors?
March 6, 20251 yr Author The parity sync completed successfully when I used a different drive as parity. Initially, I was using a 6TB Seagate drive for parity along with two 4TB WD drives for data, but the parity sync kept failing. After posting about the issue, I decided to remove the 6TB drive and use one of the 4TB drives as parity instead. This time, the sync completed without any errors.

March 7, 20251 yr Community Expert Unfortunately, there's nothing relevant logged, but if the server is crashing during a parity sync, it may be a hardware issue, and happening due to the higher load.

I got the 6TB drive replaced and it is working fine now. The issue now is that the serv er is getting disconnected automatically. syslog

The parity issue was resolved by replacing the drive. Now, the main issue is that the server randomly goes offline, and I have to restart it manually to bring it back online. The last time I booted, I saw a notification from the plugin called "Fix Common Problems" saying there was a hardware issue. However, after a reboot, that error disappeared. Despite this, the server still keeps going offline at random times.
March 10, 20251 yr Community Expert If the server is rebooting by itself, that is almost always a hardware problem, but since it's a Ryzen, make sure this has been taken care of: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/page/2/#findComment-819173
