--qcHopEYAB45HaUaB Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I just tried to do some experiments using xfs on FreeBSD 9.0RC2. My setup is: a plain file /var/cache.img attached as /dev/md0 some things work fine: fbsd9rc2# mdconfig -l fbsd9rc2# mdconfig -a -t vnode -f /var/cache.img=20 md0 fbsd9rc2# kldload xfs fbsd9rc2# mount -t xfs -o ro /dev/md0 /mnt fbsd9rc2# df -h /mnt Filesystem Size Used Avail Capacity Mounted on /dev/md0 5G 144k 5G 0% /mnt others don't: fbsd9rc2# mount -t xfs /dev/md0 /mnt mount: /dev/md0 : Operation not permitted fbsd9rc2# /usr/local/sbin/xfs_repair /dev/md0 Phase 1 - find and verify superblock...

What is xfs_repair requesting from kernel when getting stuck in umtxn? For me it's not a problem with xfs kernel support but with the xfs-tools from the ports. xfsprogs-2.9.4_3 A set of utilities and library to manipulate an xfs fil= esys FreeBSD fbsd9rc2 9.0-RC2 FreeBSD 9.0-RC2 #0: Sat Nov 12 18:35:25 UTC 2011 root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 My hardware is a virtual box 4.0.4 OSE running on linux 2.6.38-13-generic What's going on there?
