Not sure if this has something to do with it, but right about the time I was creating the lv's and snapshot, this was getting spewed into /var/log/messages: Mar 17 12:09:57 debian kernel: invalidate: busy buffer Mar 17 12:10:00 debian last message repeated 66 times Mar 17 12:11:30 debian last message repeated 134 times Mar 17 12:14:53 debian kernel: invalidate: busy buffer Mar 17 12:15:56 debian last message repeated 268 times Mar 17 12:16:54 debian last message repeated 267 times Mar 17 12:26:08 debian kernel: invalidate: busy buffer Mar 17 12:27:21 debian last message repeated 536 times Mar 17 12:27:31 debian last message repeated 200 times Mar 17 12:34:05 debian kernel: invalidate: busy buffer Mar 17 12:34:26 debian last message repeated 535 times Mar 17 12:40:44 debian kernel: XFS mounting filesystem device-mapper(254,0) Mar 17 12:46:09 debian kernel: invalidate: busy buffer Mar 17 12:46:09 debian last message repeated 66 times Mar 17 12:47:15 debian last message repeated 402 times Mar 17 12:47:16 debian kernel: device-mapper: internal error adding target to table Mar 17 12:51:40 debian kernel: invalidate: busy buffer Mar 17 12:52:11 debian last message repeated 134 times Mar 17 12:53:26 debian last message repeated 201 times Mar 17 12:53:33 debian last message repeated 401 times Mar 17 12:53:34 debian kernel: device-mapper: internal error adding target to table Mar 17 12:53:59 debian kernel: invalidate: busy buffer Mar 17 12:54:24 debian last message repeated 535 times Mar 17 12:54:24 debian kernel: device-mapper: internal error adding target to table Mar 17 13:02:11 debian kernel: invalidate: busy buffer Mar 17 13:02:34 debian last message repeated 535 times That busy buffer error on google seems realated to LVM. To give you more info I need some instructions on how to get you the debug output.

An lvs shows it there, but it does not seem to appear in /dev/vg0/ and I cannot mount it. You don't say what version you are using: see if you can reproduce the problem using the current CVS LVM2 version. Look in kernel message log for a (slightly) better error message. Turn on debugging output (log to file) and see if the last set(s) of 'Adding target' lines before you got the error make sense. Assuming the problem is still present in CVS, if you'd like me to look into it, I need a copy of the complete debugging output and to know exactly which device-mapper patches you applied to your kernel.
