Always on linux-image-3.5.0-41-generic Always on linux-image-3.8.0-35-generic I tried to interrupt init by inserting the following code: /bin/sh in '/usr/share/initramfs-tools/scripts/local' # FIXME This has no error checking # Mount root mount ${roflag} ${FSTYPE:+-t ${FSTYPE} }${ROOTFLAGS} ${ROOT} ${rootmnt} mountroot_status="$?" /bin/sh #I added this code here if [ "$LOOP" ]; then if [ "$mountroot_status" != 0 ]; then if [ ${FSTYPE} = ntfs ] || [ ${FSTYPE} = vfat ]; then and of course update initramfs after this. dmsetup is correctly show logical volumes, by command `dmsetup ls` sysraid-winxp (252, 5) sysraid-lxc_redmine_aptarchives (252, 12) sysraid-zeus--datafs (252, 11) sysraid-lxc_redmine--dev_aptarchives (252, 14) sysraid-lxc_redmine_datafs (252, 10) sysraid-lxc_redmine--dev_datafs (252, 13) sysraid-zeus--home (252, 8) sysraid-zeus--tmp (252, 2) sysraid-squiddebproxy (252, 6) sysraid-zeus--swap (252, 1) sysraid-zeus--rootfs (252, 0) sysraid-backups (252, 7) sysraid-lxc_redmine_rootfs (252, 9) sysraid-zeus--var--log (252, 3) sysraid-zeus--iso--images (252, 4) sysraid-lxc_poseidon (252, 15) sysraid-lxc_pdc (252, 16) But manual mount of root to /root of initram filesystem is break down by error that fs driver cannot find superblock. I tried to mount all other existing partitions from volume group sysraid, but they also could not be mounted because of `bad superblock` Then I tried to mount existing (/boot) partition from mdadm device (md0) and it was succesful. After that i tried to refresh logical volume's by a command `/sbin/lvm vgchange --refresh` and then mount root succefull. I decided to improve init script by following code in mountroot function in file `/usr/share/initramfs-tools/scripts/local`: # Refresh volume group's if prev attempt failed # dmsetup -v info $ROOT | grep -q 'UUID: LVM' if [ "$?" != "1" ] && [ "$mountroot_status" != 0 ] && [ -x /sbin/lvm ] then /sbin/lvm vgchange --refresh && mount ${roflag} ${FSTYPE:+-t ${FSTYPE} }${ROOTFLAGS} ${ROOT} ${rootmnt} fi It must be inserted after: ... # FIXME This has no error checking # Mount root mount ${roflag} ${FSTYPE:+-t ${FSTYPE} }${ROOTFLAGS} ${ROOT} ${rootmnt} mountroot_status="$?" #INSERT CODE HERE if [ "$LOOP" ]; then if [ "$mountroot_status" != 0 ]; then ... What do you think about this hook?
