hi

I created  btrfs file system  on one of  sda partition. when I mount
with mount -t /dev/sda17  /btrfs,

it is failing with wrong fs type bad option. when i see the dmesg,
mount command is searching  for ext3, ext2 filesystem on sda17. but
not btrfs.
even in the man page of mount, btrfs is not mentioned as supported
file system type.

Please help me to solve this issue.

thanks
rajan

remove the -t or add btrfs after it.

# mount -t /dev/sda17 /btrfs?

That doesn't work.  Maybe you meant :

# mount -t btrfs /dev/sda17 /btrfs ?

does your kernel support btrfs?  Sounds like maybe not.

To load it in case it's a module:
# modprobe btrfs

then see if the kernel even knows what btrfs is, either via the
module, or due to being built into the kernel image already:

# grep btrfs /proc/filesystems

The first cmd might fail if it's built into the kernel, but if that's
the reason, the 2nd one should find btrfs in /proc/filesystems...

If not, you need a kernel that supports btrfs.

Hi

after doing mofprobe btrfs I could see btrfs entry in proc file
system. But still mount command is failing. It looks like super block
is corrupted

thanks

You can try to recover superblocks.

Steps:

#git clone http://github.com/kdave/btrfs-progs.git 
# cd btrfs-progs
# git pull http://github.com/kdave/btrfs-progs.git  integration-20130924
# make && make install
# btrfs rescue super-recover -vy <device>


Let's see what will happen..

Thanks,
Wang

Seems doubtful if you *just* ran mkfs.btrfs.

Can you paste the exact commands you issued, from mkfs to mount,
and the resulting kernel messages?
