From: Peter Maloney To: bug-followup@FreeBSD.org, bmeyer@mesoft.com.au Cc: Subject: Re: kern/156781: [zfs] zfs is losing the snapshot directory, Date: Fri, 13 Apr 2012 09:25:16 +0200 Is the faulty dataset shared over NFS? If so, is it the new NFS server (default in 9.0 I think) or the old (default in 8.2)? My ZFS over NFS on 8-STABLE has slightly similar problems on the NFS client side, but only when viewed by a Linux client. A simple "ls -l" on the .zfs/snapshot directory on a Linux client hangs the dataset. And these lines show up in /var/log/messages when reloading the NFS server: Apr 12 10:08:38 [hostname] mountd[54479]: can't delete exports for /tank/[...]/.zfs/snapshot/replication-20120411112000: Invalid argument And an "ls" without "-l" on a Linux client shows that the ones mentioned in messages are files and the rest are directories (Linux shells generally color them blue and append a / for directories). I can only guess that they may be related.
