I am running 6.12.4 and have been running UNRAID for some time without issues.  I recently upgraded a drive from 4TB to 16TB and at the same time, moved several of the existing drives around for better cooling and organization.  I brought the system back up and everything looked correct,  and unassigned the 4TB drive from array and added the 16TB in its place.

I started the data rebuild and the system has hung multiple times since then and never successfully finished the rebuild.    It has gotten anywhere from 25 to 95% through the rebuild before hanging.

 

I have taken server apart again and rechecked all cables and cards to ensure they are connected properly and didn't see any issues.     The last time that I restarted the system, I also turned on logging to flash.  The syslog attached is copied from the flash from the last attempt to complete the rebuild.

 

I attempted to do a clean shutdown by tapping the power switch when I was unable to connect to the Web UI but am unsure of what time I did that.   I do know that it wasn't just the webui that was failing as my dockers were also not functioning.

 

Any help is much appreciated.

Try again but leave the docker and VM services disabled during the rebuild, and if it still crashes, post a new log.

Thanks JorgeB.  I am doing that.
