Btrfs filesystem is broken #643

Hi,

Somhow, my usb btrfs boot partition /dev/sdb2 became broken. There is no more possible to boot xbian from it. I tried to repair it using btrfsck tools (tried different versions 3.16.1, 3.16.2, 3.17.1) but they said there is no possible recover. (root 1351 inode 487600 errors 1000, some csum missing extent-tree.c:2330: __free_extent: Assertion owner_objectid != btrfs_tree_block_level(leaf, bi) failed. btrfs check[0x8077a09] btrfs check[0x8077a3a] btrfs check[0x8079ce6] btrfs check[0x807ab1d] btrfs check[0x8078170] btrfs check[0x807006d] btrfs check[0x80702c6] btrfs check[0x807215f] btrfs check[0x804dc9b] btrfs check[0x8065d02] btrfs check[0x804e3a6] /lib/i386-linux-gnu/libc.so.6(__libc_start_main+0xf3)[0xb746aa83] btrfs check[0x804e3cc] )

On a external linux pc I'm still able to mount the btrfs partition.

My question is how to recreate that disk and what to save from the volumes root, modules home, data ??

Thanks

@raspi1

probably not actual anymore but for future reference - if you mount XBians partition anywhere manually, you will see in the root of it few folders - it won't be the usual "root" as normally user expects. to save XBMC settings & libraries, focus on "home/@/" and all files from it it (at least xbian directory. it is XBian's home).

Closing, old issue that is no longer relevant.
