Hello, after a controller firmware bug / failure i've a broken btrfs.
# parent transid verify failed on 181846016 wanted 143404 found 143399 running repair, fsck or zero-log always results in the same failure message: extent-tree.c:2725: alloc_reserved_tree_block: BUG_ON `ret` triggered, value -1 .. stack trace .. Is there an chance to get at least a single file out of the broken fs?
