Hello, I'm getting an error when attempting to mount a volume on a host that was forceably powered off:
# mount /dev/rbd4 climate-downscale-CMIP5/ mount: mount /dev/rbd4 on /mnt/climate-downscale-CMIP5 failed: Stale file handle /var/log/messages: Jun 10 15:31:07 node1 kernel: rbd4: unknown partition table # parted /dev/rbd4 print Model: Unknown (unknown) Disk /dev/rbd4: 36.5TB Sector size (logical/physical): 512B/512B Partition Table: loop Disk Flags: Number Start End Size File system Flags 1 0.00B 36.5TB 36.5TB btrfs # btrfs check --repair /dev/rbd4 enabling repair mode Checking filesystem on /dev/rbd4 UUID: dfe6b0c8-2866-4318-abc2-e1e75c891a5e checking extents cmds-check.c:2274: check_owner_ref: Assertion `rec->is_root` failed. btrfs[0x4175cc] btrfs[0x41b873] btrfs[0x41c3fe] btrfs[0x41dc1d] btrfs[0x406922] OS: CentOS 7.1 btrfs-progs: 3.16.2 Ceph: version: 0.94.1/CentOS 7.1 I haven't found any references to 'stale file handle' on btrfs. The underlying block device is ceph rbd, so I've posted to both lists for any feedback. Also once I reformatted btrfs I didn't get a mount error. The btrfs volume has been reformatted so I won't be able to do much post mortem but I'm wondering if anyone has some insight. Thanks, Steve
