However I see messages in the kernel log > (dmesg) about write failures to the disconnected drive. > platform_check_iswritable() and platform_check_ismounted() in xfsprogs check these things. platform_check_ismounted() does a ustat() of the block device, "ustat() returns information about a mounted file system" and it knows if it's mounted or not, "EINVAL: dev does not refer to a device containing a mounted file system." so something, somewhere thinks it's mounted.

Zeroing the log won't help. - -Eric > Martin > > > # xfs_repair /dev/sdd104 > xfs_repair: /dev/sdd104 contains a mounted filesystem > > fatal error -- couldn't initialize XFS library > # xfs_check /dev/sdd104 > xfs_check: /dev/sdd104 contains a mounted and writable filesystem > > fatal error -- couldn't initialize XFS library > > > partial dmesg output: > > [346220.652432] Buffer I/O error on device sdb104, logical block > 3906961152 > [346220.652440] Buffer I/O error on device sdb104, logical block > 3906961153 > [346220.652443] Buffer I/O error on device sdb104, logical block > 3906961154 > [346220.652446] Buffer I/O error on device sdb104, logical block > 3906961155 > [346220.652449] Buffer I/O error on device sdb104, logical block > 3906961156 > [346220.652452] Buffer I/O error on device sdb104, logical block > 3906961157 > [346220.652455] Buffer I/O error on device sdb104, logical block > 3906961158 > [346220.652459] Buffer I/O error on device sdb104, logical block > 3906961159 > [346220.652473] Buffer I/O error on device sdb104, logical block > 3906961352 > [346220.652476] Buffer I/O error on device sdb104, logical block > 3906961353 > [346554.917502] quiet_error: 1924 callbacks suppressed > [346554.917510] Buffer I/O error on device sdb104, logical block 0 > [346554.917518] Buffer I/O error on device sdb104, logical block 1 > [346554.917522] Buffer I/O error on device sdb104, logical block 2 > [346554.917525] Buffer I/O error on device sdb104, logical block 3 > [346554.917529] Buffer I/O error on device sdb104, logical block 4 > [346554.917532] Buffer I/O error on device sdb104, logical block 5 > [346554.917536] Buffer I/O error on device sdb104, logical block 6 > [346554.917539] Buffer I/O error on device sdb104, logical block 7 > [346554.951030] Buffer I/O error on device sdb104, logical block > 3906961152 > [346554.951051] Buffer I/O error on device sdb104, logical block > 3906961153 > > The current disk is /dev/sdd104 and sdb104 doesn't appear anywhere in > the kernel, despite the messages in dmesg. > > # cat /proc/partitions > major minor #blocks name > > 7 0 131072 loop0 > 8 0 488386584 sda > 8 1 204800 sda1 > 8 2 104384512 sda2 > 8 3 1 sda3 > 8 4 15471640 sda4 > 8 5 30403584 sda5 > 8 6 104391 sda6 > 8 7 117187584 sda7 > 11 0 1048575 sr0 > 8 64 1953481728 sde > 8 75 1953480687 sde11 > 8 80 312571224 sdf > 8 48 1953481728 sdd > 259 0 1953480687 sdd104 > > > > _______________________________________________ > xfs mailing list > xfs@xxxxxxxxxxx > http://oss.sgi.com/mailman/listinfo/xfs > -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJTY7QVAAoJECCuFpLhPd7gh8sP/3etms+dvasiiUX6dEwoGf4C uiZarjqYG6liwMgBgtsfBfHs35p5r70kab55kf6keAx0zIvFewQbyCGKZ931Ok1B c0XgXaBVrSCzEtgRAJjJMDnIguEOCn0E/duIkjRcq7Gp8lcb1C83yr9fJ16HMYaz xdYy1Gc3VeDmVAZ3Bf3ojXu1Uqeaa0QZjFSTx7cdUXtsftxtIO906snqU+xc8+pr BPwzneWntEYiR8Fy5ZyjFCwnhlLnfRwu/EivUkLCcNIBHANko12Uzf/0t0xvcTGQ z+VZzmZF5Us8ytFsTqfP6a55jQeWU5p2jr7flRSLnjDZ3RK3wUXIK1Yvngq+zTc6 57o2EhNNBTjqLkIzqDG5rAJYVNsv/9gIR3u7QzbdpzquwSHborfUDLS9Ss3saK8D Qk7FgyM72sNyI5KntO0/HFc443Qvj3ptWfgFengCSd8pDklnIGMC2ykT2MRVazm4 QmeX9XCQ40SZ6y/X67dMrR6hLMSbij7XXZkRjOAFTWkePLNvo2RjzHBW8gFEybHM d/uFP5HWGtKqUEgwUoQWQ+U/MENv878UqT1Hq7XRNtt+TCWNQQOzuAMbdUSniuCG V1WFVZEKsKqmzBJ5bdOLXmkUPXcV73Ou2vvTfRqDCHcPIKJTd9Yq/lNZAE5I6NiE mM4LhitVZUvUn/94NGvX =m/u5 -----END PGP SIGNATURE----- _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
