using v0.19 on ubuntu 10.4
i have a raid0 meta and data across 2 drives (sdf, sdg); i recently added another drive to the mix using 'btrfs-vol -a /dev/sde'. it returned 'ioctl returns 0'.
i didn't think anything of it as the extra disk showed up.
i did not do a rebalance. but i did write some stuff to the array.
$ btrfs-show
failed to read /dev/sr0
Label: none uuid: ea7ea0b3-bc42-4b0c-9173-346df61d4454
Total devices 3 FS bytes used 3.51TB
devid 3 size 1.82TB used 0.00 path /dev/sde
devid 1 size 1.82TB used 1.82TB path /dev/sdf
devid 2 size 1.82TB used 1.82TB path /dev/sdg
however after a rebooted i can now only mount the disk in degraded mode.
$ mount -t btrfs /dev/sdf /mnt/stripe/
mount: wrong fs type, bad option, bad superblock on /dev/sdf,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
dmesg:
[ 107.977464] device fsid c4b42bcb3a07eea-54441df66d347391 devid 1 transid 8747 /dev/sdf
[ 107.977932] btrfs: failed to read the system array on sdf
[ 108.000143] btrfs: open_ctree failed
any suggestions on how i can get out of this pickle? (except for copy all the data off the drives)
