I'm having an issue very similar to this:
www.truenas.com
Two days ago, I started getting alerts about offline sectors on one of my disks. The number of sectors in the alerts has been steadily increasing, so I have a replacement drive arriving today. However, twice now I've found the whole system unresponsive and needing to be reset via IPMI. When unresponsive, the "swap_pager: indefinite wait buffer" messages are spammed to the physical console. I wasn't able to log into the GUI or on the physical console to get any more information. Even trying to reboot from the menu would hang.
With the disk errors appearing right before these hangs, it seems evident that the swap space on the affected disk is likely causing OS issues and when I replace the disk it will resolve. The question I have is: is this expected, or is there something I have misconfigured? Under Advanced settings, the swap size is set to 2GB, and I don't see anything else related to system swap. It just seems out of character for a TrueNAS system to be completely crippled by one bad disk.
Any insight is appreciated!
FreeNAS swap_pager: indefinite wait buffer
