update to 11.1 or newer to avoid SWAP on a failing hard drive crashing freenas GUI

[R wkgs]

One of our freenas servers 11.0-u2 has crashed due to swap space on a failed drive taking out windows file sharing and the web GUI. This issue is apparently resolved in 11.1 https://redmine.ixsystems.com/issues/23523

Same issue as https://forums.freenas.org/index.ph...crash-with-unexplained-log.53865/#post-372899

Glad to see it fixed as despite having 32GB ram the system apparently was using swap on that hard drive for critical services.

Question is: Dose the update auto mirror swap on updated systems or would I be better rebuilding all our servers to prevent this happening again?

Note: have had hard drives fail before but this is the first time its taken the GUI and other services out.

lots of this on screen:

Code:

> 6
> vm_fault: pager read error, pid 1652 (devd)
