retitle 712078 fsck.btrfs not working due to argv[0] inspection thank you the problem you describe is much more general, as shown by this comparison:
> $ /sbin/fsck.btrfs /dev/null > btrfs: unknown token '/dev/null' > usage: btrfs [--help] [--version] <group> [<group>...] <command> [<args>] > [...] > > $ /sbin/btrfsck /dev/null > No valid Btrfs found on /dev/null given /sbin/btrfsck and /sbin/btrfs are identical, it seems to me that that binary decides what to do based on the name it is invoked as (just like busybox). that failes when invoked as the symlink fsck.btrfs -> btrfsck. the trivial fix is to replace the /sbin/fsck.btrfs symlink by a shell script: > #!/bin/sh > /sbin/btrfsck $@ a better thing to do might be to add fsck.btrfs to the list of accepted names in order to start an fsck run. best regards chrysn
