Hi all.
I have a two-disk mirror which has suddenly stopped having any files, according to `ls -a`. In every other way it seems fine.
According to `df -h` and similar tools it's fine, and has 490 GB of files. `zpool status`, `zfs mount` and `zfs list` show what I'd expect.
Any advice on how to diagnose the problem?
This is using 1.6.1.
Thank you.
