Hello,
I am not clear on where the error is coming from, therefore I'm uncertain of where to post this.
It started about 2 weeks ago with a daily ZFS snapshot getting stuck around midnight, I believe it was taking a snapshot of a filesystem on ada5, which is part of a mirror with ada4 encrypted with geli(). The next day the computer froze and I had to power off the system. I had to reboot three times for the boot drive to be found. Once it started to reboot I received the following error message repeatedly:
I had another stuck ZFS snapshot a few days ago on ada5 directory, but I was able to shut the computer down before there were problems. Upon reboot I received the same message as above.
smartd reports no errors with any of the drives.
Yesterday, while editing a file in Emacs the user space, KDE, froze with a screeching noise from the speaker. I was not able to do anything in the user space and, since I had no other device to SSH in with, I did a hard power cycle again. Upon reboot, the same issues as above and the file that I had been working with in Emacs had been overwritten and was 0kB in size. I am unclear if these things are related, as I had similar issues in the distant past with Emacs that seemed to go away with an update of the port.
Essentially, I am looking for help on trying to figure out what is wrong with the disk, geli or ZFS here. This is my workstation and I have a grant due in the next week. I cannot afford to upgrade anything as sometimes upgrades don't work.
All the filesystems, including the boot drive, are ZFS. The output of
And my system:
Thanks very much for any suggestions.
