zfs panic mounting fs after crash with RC2

Hi, Yesterday I had the opportunity to play around with my yet-to-become new fileserver a bit more. Originally I had installed 7.2-R, which I upgraded to 8-0-RC2 yesterday. After that I upgraded my zpool consisting of 4 disks in raidz1 constallation to v13. Some time later I tried to use powerd wh

Linux/KDE and NFS locking on 7-stable

Hi all, I upgraded a FreeBSD fileserver last week from 7.0-stable to 7.2-stable and experience some weird problems now with Linux NFS clients. The Linux Clients mount their home directories via nfs. I usually use "nolock" on the client side, because file locking was always troublesome in the past.

Hi folks, I just upgraded a zfs server from 7.0-something to 7.2-stable and hoped to get rid of some minor instabilities I experienced every 6 months or so. Unfortunately, the new system crashed for the first time after only a few hours when copying some files via scp onto it. I got a kernel panic

Hi all, I have several machines here that do automatic snapshotting via RSEs snapshot-tool (sysutils/freebsd-snapshot). I use a homemade script to incrementally transfer daily snapshots to a backup server. This runs fine with machines running 7.0-STABLE of Jun 08. However, I have one box with 7.1-

zfs crashes with nfs and snapshots

Hi folks, I just saw one of my FreeBSD servers (7.0-stable of June 2008) crash while trying to access the .zfs snapshot directory via a nfs client machine. The server got a page fault caused by the nfsd process. It wasn't even able to dump the kernel image anymore. Resetting the machine it first a
