This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig13188AE437CB5222F5654835 Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: quoted-printable I've just had a failure case when one drive of a gmirrored pair=20 apparently failed. Here's what's in system messages: Mar 24 01:31:28 xx ad2: FAILURE - device detached Mar 24 01:31:28 xx subdisk2: detached Mar 24 01:31:28 xx ad2: detached Mar 24 01:31:28 xx GEOM_MIRROR: Device gm0: provider ad2 disconnected. Mar 24 01:31:28 xx g_vfs_done():mirror/gm0s1f[READ(offset=3D578404352,=20 length=3D16384)]error =3D 6 Mar 24 01:31:28 xx g_vfs_done():mirror/gm0s1h[READ(offset=3D12525010944, = length=3D2048)]error =3D 6 What interests me is: - there were no prior messages of the drive failing (I'd expect=20 geom_mirror to complain earlier) - why does it look like the IO request(s) that caused the failure to be=20 detected are themselves failed? I.e. it looks like two IO requests were=20 discarded at the geom_mirror level, while I'd expect them to be=20 completed from the other, working drive. Any ideas / comments? --------------enig13188AE437CB5222F5654835 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFH5/88ldnAQVacBcgRAkPTAJ9QPBVD73SsT2FOdaeZFZMcIYgH7QCglhWi jhFG0YI1SS1MYnjt4lKixD8= =i0iJ -----END PGP SIGNATURE----- --------------enig13188AE437CB5222F5654835--
