Today, I tried to copy a lot of files from a windows 10 machine to my zfs mirror raid.
After a couple of Gb The windows machine lost contact and when I try to connect to the share I get "Communication Failure" without any more info than that.
The bad part is that I also get Communication failure when I try and investigate the pool on the ZFS page.
I cannot even reboot the system from the GUI, so something is really bad.
What can I do to find more info on this? The log does not show anything odd.
