My zfs hangs (all IO) if I go into the .zfs/snapshots directory over NFS. (planning to file a PR after I find a way to reproduce it reliably, but it depends on specific snapshots). My workaround is to mount /var/empty on top of the .zfs directory on the nfs client, and give nobody else access. Another workaround I thought of is to have another parent directory in the dataset, and share the 2nd level down which doesn't contain the .zfs directory. And a single dataset hangs if I rename a ZVOL snapshot (likely not the only way to cause this): http://www.freebsd.org/cgi/query-pr.cgi?pr=161968 I am using: FreeBSD bcnas1.bc.local 8.2-STABLE FreeBSD 8.2-STABLE #0: Thu Sep 29 15:06:03 CEST 2011 root@bcnas1.bc.local:/usr/obj/usr/src/sys/GENERIC amd64 On 12/13/2011 03:34 PM, Johannes Totz wrote: > Hi! > > Is failmode=continue for zpool working correctly? > > I have a test pool sitting on the network (which drops out every few > hours) but all io eventually just hangs instead of failing. > > To get the pool back up running (and get rid of all the hung > processes) I always need to reboot the machine.
