Had an unexpected power fail during the night and now my os crashes when mounting / Most of my data is backed up, but there is some data which I don't want to lose on the partition... I put the drive in a SATA - USB cradle and hooked it to my fedora 13 laptop which promptly became unresponsive. So I upgraded the laptop to fc15 and installed the latest 2.6.39.1 kernel from rawhide. When I try to mount the first time I get the following crash: http://pastebin.com/qA3kztzh but at least the system stays alive. When I manually try to 'mount /dev/sdb5 /mnt' the process just stalls, can't even crtl+c to quit. On recommendations from the IRC folks I compiled the git btrfs-progs-unstable including the 'btrfs-zero-logs' tool. I have tried running the tool against the affected partition to no avail, no error messages either. btrfsck reports no errors either: http://pastebin.com/P4uXteLC I have no idea where to go from here, if anyone can help it would be much appreciated!
