I'm playing with btrfs under vanilla kernel 3.12.0 (and tools Btrfs v0.20-rc1-358-g194aa4a) and finding a few strange things.
My volume doesn't mount on its own at boot even though I have in /etc/fstab
| Code: | | /dev/sdb /z btrfs defaults,compress=lzo 0 1 |
Manually mounting results in
| Code: | mount -t btrfs /dev/sdb /z
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so. |
But after I do which gives no output other than Scanning for Btrfs filesystems, the mount command works.
I can't make snapshots of the root volume. Running
| Code: | | btrfs subvolume snapshot -r /z /snaps |
results in
| Code: | Create a readonly snapshot of '/z' in '/snaps/z'
ERROR: cannot snapshot '/z' - Inappropriate ioctl for device |
Am I doing things wrong or are these bugs? |
