.zfs directory broken on an FS

[Daniel O'Connor]

I recently switched over to ZFS at work and it seems pretty good (so far at least!) however I was writing a script to do snapshots and one of the file systems now gives..

[cain 9:37] ~ >ls -la /usr/local/Genesis/archive/.zfs
ls: snapshot: Bad file descriptor
total 0

Other file systems in the same pool work fine though..
[cain 9:36] ~ >ll /usr/local/Genesis/MeteorData/.zfs/snapshot
total 4
drwxrwxr-x  32 metdata  radar  38 Mar 21 03:11 20100512-0900

(All other snapshot directories are OK)

I haven't tried rebooting it yet.

Any suggestions, or information to help debug it?

The system is..
FreeBSD cain.gsoft.com.au 8.0-STABLE FreeBSD 8.0-STABLE #0 r206332: Wed Apr  7 11:01:52 CST 2010     root at cain3.gsoft.com.au:/usr/obj/usr/src/sys/GENERIC  amd64
