Hi after doing mofprobe btrfs I could see btrfs entry in proc file system. But still mount command is failing.

Hello, 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 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..

It looks like super block is corrupted 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? -Eric thanks rajan -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Maybe you meant : # mount -t btrfs /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. 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. -Eric thanks rajan -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line unsubscribe linux-btrfs in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
