Title:
file system lockup with zfs hung task
Status in linux package in Ubuntu:
Expired
Bug description:
I am running an Ubuntu 16.04 server running on an HP Proliant chassis
with several lxc containers running on zfs. While performing a series
of debian updates on the host and container, as well as container
destruction/creation, the kernel spits out a stack trace indicating
that the there was a hung task while it was performing writeback in
zfs.
If I attempt to perform a "sync" command on the host, the command will
not return. Also, if I attempt to reboot the server with the reboot
command, the server never reboots. A power cycle is required.
