Ran into this today (in a VM I hadn't upgraded for a while); looks
like it was caused by
* Removing fsck.btrfs symlink to circumvent that btrfsck doesn't
support -a.
in version 0.19-11. Which makes sense --- btrfsck doesn't know how to
repair filesystems with guidance from the user yet, so it certainly
can't automatically repair them.
Still, I believe it would be best to allow btrfsck to act as fsck when
the filesystem is not broken. Would some script along these lines
make sense?
#!/bin/sh
# fsck.btrfs - Wrapper for btrfsck to work around the latter's
# lack of support for "-a".
shell_quote () {
# Wrap stdin in single-quotes,
# quoting embedded single-quotes as '\''.
sed -e "s/'/'\\\\''/g" \
-e "s/.*/'&'/"
}
args=
while test "${1+set}"
do
if test "$1" = -a
then
echo >&2 'warning: btrfsck cannot repair filesystem
corruption!'
else
args="$args $(printf "%s\n" "$1" | shell_quote)"
fi
shift
done
eval "exec btrfsck $args"
Thanks,
Jonathan
