Hi folks! Been using btrfs for quite a while now, worked great until now. Got power-loss on my machine and now i have the "parent transid verify failed on X wanted X found X" problem. So I can''t get it to mount. My btrfs is spread over sda (2tb), sdc(2tb), sdd(1tb). Is this something that an offline fsck could fix ? If so is the fsck-util being developed ? Is there a way to

I have accidently damaged the first block(s) of a btrfs partition and can''t mount it anymore. I can see that my data is still intact by running a command like: cat /dev/sda5 | hexdump -C | more Do any (experimental) tools exist which would allow me to recover the files?

...en running btrfs (RAID 1 for both data and metadata). Unfortunately, earlier today it seems one of the SATA cables came loose, resulting in the kernel (2.6.37) eventually OOPSing although apparently not before writing quite a bit of data. Upon reboot, I was met with the dreaded, disk-io.c:741: open_ctree_fd: Assertion `!(!tree_root->node)'' failed. Unfortunately any attempt to run any of the btrfs-progs utilities (from git) met a similar end. There was recently a patch to try harder in recovering from this problem posted to the list[1], although unfortunately it is unable to find a root. C...
