Hi folks.
Last night one of the USB attached disks malfunctioned during a
balance. I strongly suspect the drive will die soon. A couple hours
later, with the drive cold, I got a
Dec 8 07:34:49 adams kernel: [84890.433235] device label quatrocentao
devid 1 transid 1659 /dev/sde1
Dec 8 07:34:49 adams kernel: [84890.460448] btrfs: open_ctree failed
I ran btrfsck on it and got
root@adams:~# btrfsck /dev/sde1
found 396558811136 bytes used err is 0
total csum bytes: 385961240
total tree bytes: 1334501376
total fs tree bytes: 756809728
btree space waste bytes: 346120636
file data blocks allocated: 396065329152
referenced 396065329152
Btrfs Btrfs v0.19
But, when I tried to mount it, I got the much feared:
root@adams:~# mount /dev/sde1 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sde1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Running Ubuntu 11.04 here.
Now would be a terrific time to have a "salvage broken filesystem"
utiliy so I could move the data to another disk. Are we there yet?
