unable to mount btrfs file system

Binoy NazarethJul 27 2015 — edited Jul 31 2015

/u01 did not come back after a reboot and now I get this error:

[root@ccpora-br-c010-p ~]# mount -a

mount: No space left on device

I see this in /var/log/messages:

Jul 27 17:40:18 ccpora-br-c010-p kernel: btrfs: disk space caching is enabled

Jul 27 17:40:19 ccpora-br-c010-p kernel: btrfs: could not do orphan cleanup -28

Jul 27 17:40:21 ccpora-br-c010-p kernel: btrfs: open_ctree failed

I tried running a repair and it aborts:

[root@ccpora-br-c010-p ~]# btrfsck --repair /dev/VG_00/LV_u01                   enabling repair mode

Checking filesystem on /dev/VG_00/LV_u01

Any ideas or suggestions would be appreciated.
