After multiple power outages caused by storms coming through, I can no
longer access /dev/zvol/dsk/poolname, which are hold l2arc and slog devices
in another pool I don't think this is related, since I the pools are ofline
pending access to the volumes.
I tried running find /dev/zvol/dsk/poolname -type f and here is the stack,
hopefully this someone a hint at what the issue is, I have scrubbed the pool
and no errors were found, and zdb -l reports no issues that I can see.
