This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig1A8FB78AEA4D6626C31A47B7 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hi, One of the machines I take care of started recently started recording messages such as these in the logs: Feb 28 04:02:09 skynet kernel: fsync: giving up on dirty Feb 28 04:02:09 skynet kernel: 0xfffffe000fef2780: tag devfs, type VCHR Feb 28 04:02:09 skynet kernel: usecount 1, writecount 0, refcount 2400 mountedhere 0xfffffe000fd25200 Feb 28 04:02:09 skynet kernel: flags () Feb 28 04:02:09 skynet kernel: v_object 0xfffffe000fe96d98 ref 0 pages 23= 990 Feb 28 04:02:09 skynet kernel: lock type devfs: EXCL by thread 0xfffffe000feb5000 (pid 44968) Feb 28 04:02:09 skynet kernel: dev multipath/hpdisk4-web I'm leaning towards suspecting bad hardware - the device behind "multipath/hpdisk4-web" is an old HP MSA FC storage (which I wouldn't recommend to anyone), but though verbose, the message lacks device-level specifics. I would expect messages to be logged by the isp driver, or the CAM layer, or even GEOM, but there is nothing there - only this "fsync" message. =46rom the code, it looks like an transient condition (printed in the cas= e of EAGAIN), but the hardware here is behaving a bit suspect so I'd like to make sure - should I ignore this message? --------------enig1A8FB78AEA4D6626C31A47B7 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk9OB00ACgkQldnAQVacBcj7FgCfSUqoXYRAPBW2EhRKVTUUx2lg rJIAoKgpdh6B5xejCwIr6Lv3AoShvtht =Ucqp -----END PGP SIGNATURE----- --------------enig1A8FB78AEA4D6626C31A47B7--
