I'm using Ubuntu 12.04.2 and I'm facing same problem. I did a fresh install from alternate cd (amd64). Raid 1 and lvm volumes were created before installation.
With kernel 3.5.0-23-generic everything is working but it isn't with 3.5.0.31-generic. I'm getting those lines : md1: unknwon partition table device-mapper: table: 252:0: linear : Device lookup failed 1) I've noticed I could activate volume by doing vgchange -ay on busybox prompt. 2) Adding this to /etc/udev/rules.d/85-lvm2.rules solved the problem. SUBSYSTEM=="block", ACTION=="add|change", ENV{ID_FS_USAGE}="raid", \ RUN+="watershed sh -c '/sbin/lvm vgscan; /sbin/lvm vgchange -a y'" How could I check ID_FS_USAGE value ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/147216 Title: LVM filesystems not mounted at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/147216/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
