Subject: fuser fails to list processes that have a directory on a btrfs filesystem as their current working directory
Date: Fri, 26 Jun 2015 18:23:37 +0200 [thread overview]
Message-ID: <mmjua9$bjp$1@ger.gmane.org> (raw)
JFYI: Not a btrfs bug, but a btrfs-specific misbehaviour of "fuser" that
might easily be misinterpreted as a btrfs bug:
http://bugzilla.centos.org/view.php?id=8966
> /usr/sbin/fuser (from psmisc-22.20-8.el7.x86_64) does not list any processes that have a directory on a btrfs file system as their current working directory.
>
> (For file systems other than btrfs, this works.)
> Steps To Reproduce:
> mkdir /some/btrfs/testdir
> cd /some/btrfs/testdir
> fuser -v -m /some/btrfs
>
> This should list your current shell as one of the processes using the /some/btrfs file system, but it doesn't
>
> The same on /some/xfs/testdir works fine.
> This bug is not present in upstream "psmisc" sources as of current master in
> git://git.code.sf.net/p/psmisc/code
>
> An fuser executable compiled from the current upstream sources works fine also for btrfs.
