Still it would be nice to get a btrfs check mode which would include trying destructive actions, as in accepting the loss of some part of user data (outright delete corrupt blocks, etc), just to restore the filesystem itself to a fully correct and mountable state. Sometimes there are cases when it is inconvenient to recreate the entire FS (remember seeing 40TB mentioned recently), just to fix a few "parent transid failed", not even many transactions apart. And the data itself is often backed up, so restoring only the missing part from the backup would be much easier. -- With respect, Roman
