I have a few systems running on ZFS with a backup script that creates
snapshots, then backs up the .zfs/snapshot/name directory to make sure
open files are not missed. This has been working great but all of the
sudden one of my systems has stopped working. It takes the snapshots
fine, zfs list -t spnapshot shows the snapshots, but if you do an ls
command, on the .zfs/snapshot/ directory it returns not a directory.
part of the zfs list output:

zroot/home 144K 29.7G 122K /home

Does work at the right now, since the last reboot, but wasn't always
working, this is my boot environment.
if I do ls /home/.zfs/snapshot/, result is:
ls: /home/.zfs/snapshot/: Not a directory
if I do ls /home/.zfs, result is:
ls: snapshot: Bad file descriptor
shares
I have tried zpool scrub zroot, no errors were found, if I reboot the
system I can get one good backup, then I start having problems. Anyone
else ever ran into this, any suggestions as to a fix?
System is running FreeBSD 9.1-RELEASE-p5 #1 r253764: Mon Jul 29 15:07:35
CDT 2013, zpool is running version 28, zfs is running version 5
I can say I've had this problem. Not certain what fixed it. I do
remember I decided to stop snapshoting if I couldn't access them and
deleted existing snapshots. I later restarted the machine before I went
back for another look and they were working.
So my guess is a restart without existing snapshots may be the key.
Now if only we could find out what started the issue so we can stop it
happening again.
