Long time ago, but IIRC gamin does not have this problem. famd also should support client/server where local famd contacts famd on NFS server to request monitoring of NFS filesystem. Not sure whether this is build-time selectable. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iEYEARECAAYFAlJLCH0ACgkQR6LMutpd94zc8QCfe/LWgAjyLhRVBYRiPQSctEgs tUsAoMq9gjZ58ifnDA66GTxdemD92Od9 =EzSI -----END PGP SIGNATURE-----

ain't that pretty obvious ? systemctl restart fam will terminate famd first, when that happens all resources are freed. However I suspect what you are seeing is a bug, missing closedir() somewhere in famd. -- "If debugging is the process of removing bugs, then programming must be the process of putting them in." - Edsger Dijkstra -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

If my memory serves me right, famd operates on file descriptor, so it must have file open to monitor it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

You are missing the point. I know what a restart of famd does, that's why I do it. I have to, in order to umount some external mounts, because famd keeps a hold on that filesystem for hours. I had seen this behaviour years ago, then it dissapeared, and now it is back.
However I suspect what you are seeing is a bug, missing closedir() somewhere in famd.
So I guess that a bugzilla is wanted... - -- Cheers, Carlos E. R.

It might not be a bug if as Andrey said famd needs this DIR * open for monitoring. -- "If debugging is the process of removing bugs, then programming must be the process of putting them in." - Edsger Dijkstra -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That is absurd. I have the right to close mounts at the time of my choosing without being root to restart fam. -- Cheers / Saludos, Carlos E. R. (from 12.3 x86_64 "Dartmouth" at Telcontar)

Worse. The server publishing via nfs the directory "/data/hoard/" was stopped. This rendered the client machine very unstable: any process trying to do a listing of /data locked up, had to killed -9. Notice "/data", not "/data/hoard/". I had to reboot the machine to recover it up. -- Cheers / Saludos, Carlos E. R. (from 12.3 x86_64 "Dartmouth" at Telcontar)

Counterintuitive I will say... I have the right to close mounts at the time of my
choosing
Computer does not know about your rights of course :-) -- "If debugging is the process of removing bugs, then programming must be the process of putting them in." - Edsger Dijkstra -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
