Deadlocks: anyone else seeing this with 1.7.2?
Posted: Fri Oct 12, 2018 10:37 am
I updated my zfs install from 1.5.2 to 1.7.2 about six weeks back. I did not upgrade my main pool, but I did create a new pool on my mirrored backup drive that uses the native ZFS encryption. Since then, and it could be entirely coincidental, I've been getting occasional deadlocks while running Carbon Copy Cloner (still on version 4.1.23). While logged in as my admin user I have CCC set up to first clone my HFS+ El Capitan boot partition to an encrypted HFS+ partition on the external drive, then it clones my user directory from the ZFS dataset holding my everyday (non-admin) user account.
I back up weekly, and the problem shows up about half the time, so I've seen it happen three or four times: progress stops on CCC, then the disk activity appears to stop. If I try to switch Activity Monitor, or open the Force Quit dialog I get a spinning beach ball of death, which quickly spreads to anything I try to do: can't activate a Terminal window, can't switch tabs or activate Activity Monitor, can't switch to Console. Curiously, I've only seen it happen during the first task, the one that doesn't even involve ZFS.
Well, dang, looks like it just happened again now as I was typing this Excuse me while I reboot.
