Hello! In an attempt to finally get a recent Xen dom0 kernel booted on this pesky amd64 system (see <http://lists.xensource.com/archives/html/xen-users/2009-10/msg00485.html> for the (short) story), I wanted to give this one one a try: Marco Nenciarini <mnencia at prato.linux.it> wrote: > I've applied latest forward ported patches from > >

Hi, using btrfs with LVM snapshots seems to be confusing /proc/mounts After mounting a snapshot of an original filesystem, the devicename of the original filesystem is overwritten with that of the snapshot in /proc/mounts. Steps to reproduce: arnd@kallisto:/mnt$ sudo mount /dev/vg0/original /mnt/original [ 107.041432] device fsid 5c3e8ca2-da56-4ade-9fef-103a6a8a70c2 devid 1 transid 4 /dev/mapper/vg0-original [ 107.044691] btrfs: no dev_stats entry found for device /dev/mapper/vg0-original (devid 1) (OK on first mount after mkfs) arnd@kallisto:/mnt$ cat /proc/mounts | grep...

...ad the story. I have couple of 1U machines. They all have two, four or more Fujitsu-Siemens SAS 2,5" disks, which are bounded in Raid1 pairs with Linux mdadm. First pair of disks has always two arrays (md0, md1). Small md0 is used for booting and the rest - md1 is used as PV for volume group (vg0). When I need to enlarge the volume, I just add 2 new disks, create a raid 1 array of their whole space I add it as another mdX to vg0. That has been working fine since yesterday. I received new disks branded by Toshiba (Toshiba bought Fujitsu-Simens hdd business) which were supposed to be added...
