This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigE7F1DEF35E2B614F39635BA7 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hello list, Basically I'm experiencing the same problem as described here : https://forums.freebsd.org/showthread.php?t=3D9407 (linking for reference= ) Drives disconnections are not recognized instantly, and instead I get the following dmesg entries : mpt0: mpt_cam_event: 0x16 mpt0: mpt_cam_event: 0x16 (Sometimes I also get "mpt0: mpt_cam_event: 0x12" events) This is really crippling as this litterally paralyzes the ZFS pool until the controller finally comes to its senses (...or until a disk gets replugged in, which provokes a flush of all the buffered failed SCSI requests). Hardware is recognized as : mpt0@pci0:6:8:0: class=3D0x010000 card=3D0x1f041028 chip=3D0x00541000 rev= =3D0x01 hdr=3D0x00 vendor =3D 'LSI Logic (Was: Symbios Logic, NCR)' device =3D 'SAS 3000 series, 8-port with 1068 -StorPort' class =3D mass storage subclass =3D SCSI Did anyone else experience this, or find a proper work-around ? Thanks in advance for your time, --=20 Stephane LAPIE, EPITA SRS, Promo 2005 "Even when they have digital readouts, I can't understand them." --MegaTokyo --------------enigE7F1DEF35E2B614F39635BA7 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktWzU0ACgkQ24Ql8u6TF2PHOwCg72hxd9fwISEgt4OAVTbRiBuS FTwAoJuIQL3kYlmtXN48swDcHulk8YDK =7jM8 -----END PGP SIGNATURE----- --------------enigE7F1DEF35E2B614F39635BA7--
