Panic - Error 61 from traverse dataset destroyed

[augbert]

I tried to delete an unused container volume from a degraded zfs pool last night and rebooted the server afterwards. On boot the server is hanging with the following error

"Panic: Error 61 from traverse_dataset_destroyed"


I can get back into the server if I either disable the ZFS pool or pull the drives so it can't import the pool but when I try to bring the pool back online either from plugging in the drives while it is currently running or booting like normal it throws that error out. I can not seem to find anything on this error so here we are. Also, making the assumption that the ZFS pool is probably unrecoverable and will have to rebuild it which isn't the end of the world but if possible would like to try to recover it.

Try replacing the failed drive that degraded the pool and let it finish resilvering, but my gut instinct is that the pool may need advanced-level intervention. Might be faster just to recreate it and restore

In the future, try bringing the pool back to "normal" - stable, non-degraded-state - before messing with it.
