Hi there, after my filesystem is broken (I have no idea why, because last shut down was nomal) I tried to repair it with btrfsck ( Btrfs v0.20-rc1-56-g6cd836d). But unfortunately the process breaks with: parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 parent transid verify failed on 29896704 wanted 392661 found 395689 Ignoring transid failure checking extents...

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 mount the FS in a read-only mode or somethi...

...ems, especially when we want to make a random write on a large file, e.g a 4G file. Then a idea for this suggested by Chris is to use sub transaction ids and just to log the part of inode that had changed since either the last log commit or the last transaction commit. And as we also push the sub transid into the btree blocks, we''ll get much faster tree walks. As a result, we abandon the original brute force approach, which is "to delete all items of the inode in log", to making sure we get the most uptodate copies of everything, and instead we manage to "find and merge&quo...

...ts (blocked=1) or when it has done it''s dirty work (blocked=0). The second patch adds ioctls that let you start and wait for an asynchronous commit. The third introduces a SNAP_CREATE_ASYNC ioctl that creates a snap but returns before it hits disk. The fourth patch returns the commiting transid to userspace, so that it can be fed to the WAIT_SYNC ioctl. I''m not that happy with the interface, though; any suggestions for alternatives would be great. Alternatively, I could get by without knowing the exact transid and it wouldn''t be the end of the world. The final patch l...
