I'm trying to mound /dev/mapper/Volume01-lvusr on my fstab and found no such files and later found it was created as /dev/md-* After uncomment the 2 line on /etc/udev/rules.d/50-udev.rules KERNEL="dm-[0-9]*", NAME="" KERNEL="dm-[0-9]*", PROGRAM="/sbin/devmap_name %M %m", NAME="%k", SYMLINK="%c" It did help a bit the Logical Volume was created under /dev lrwxrwxrwx 1 root root 4 Apr 22 12:38 /dev/Volume00-lvroot -> dm-3 lrwxrwxrwx 1 root root 4 Apr 22 12:38 /dev/Volume00-lvusr -> dm-4 lrwxrwxrwx 1 root root 4 Apr 22 12:38 /dev/Volume00-lvvar -> dm-5 lrwxrwxrwx 1 root root 4 Apr 22 12:38 /dev/Volume01-lvroot -> dm-2 lrwxrwxrwx 1 root root 4 Apr 22 12:38 /dev/Volume01-lvusr -> dm-0 lrwxrwxrwx 1 root root 4 Apr 22 12:38 /dev/Volume01-lvvar -> dm-1 My Questions are 1) Why the link is not created under /dev/mapper/ ? 2) Why the Volume Group dir was not created? 3) When multipath-tools was emerge a new rules is added in udev does that change the way of 50-udev.rules playing, They seem to be doing the same jobs.

Find the Resolution. The file from multipath-tools /etc/udev/rules.d/40-multipath.rules Seem to be the problem. 1) If multipath-tools is not emerged /dev/Volume00/ will not be created because of lacking of /sbin/devmap_name 2) After multipath-tools is emerged the new rules apply and stop the Golume group to be working. Resolution Add one more line to the files. KERNEL="dm-[0-9]*", NAME="" before KERNEL="dm-[0-9]*", PROGRAM="/sbin/devmap_name %M %m", NAME="%k", SYMLINK="%c" A patch have been created.
Created attachment 56975 [details, diff] 40-multipath.rules Patch Different that will re create the Volume Group.
Please check with other and if there is any other reason for not using this. Checking this into sys-fs/multipath-tools will solve the problem.
Comment on attachment 56975 [details, diff] 40-multipath.rules Patch Not related...
Created attachment 56982 [details, diff] /etc/init.d/checkfs.diff Forget about comment 2 until 3. they are not related. What I do to solve the problem is to do more then once /sbin/vgchange then the /dev/Volumexx will be there. Don't know why maybe is a LVM bug. I've sys-fs/lvm2 static On /etc/portage/package.use Don't know if it is related... will reemerge later.
lvm issue, not a udev one.
What? Consider this solved and INVALID? I though this will be move to LVM2 BUG? Update... Reemerge lvm2 don't help.

reopened as bug 96405
*** Bug 96405 has been marked as a duplicate of this bug. ***
Reopened wrt Bug 96405.
Please note I also upgraded my baselayout to baselayout-1.11.12-r4 from baselayout-1.9.4-r7 The file /etc/init.d/functions.sh which seems to handle volume mouting has been changed. The old one: maurice@thewarehouse2 init.d $ grep -rs lvm functions.sh maurice@thewarehouse2 init.d $ [nothing found] The new one: maurice@thewarehouse4 /etc/init.d $ grep -rs lvm functions.sh for x in ${RC_VOLUME_ORDER-raid evms lvm dm}; do for x in $(reverse_list ${RC_VOLUME_ORDER-raid evms lvm dm}); do maurice@thewarehouse2 init.d $ I think the bug has something to do with this change and not with lvm2 or udev.
lvm code has been moved out of checkfs and into /lib/rcscripts/addons/lvm-start.sh the posted patch is a hack workaround, not a real fix
Seem to be fixed in the new version...
I am experiencing a similiar problem to this. My lvm volume groups fails to be activated and therefore mounted on boot (via fstab). I have to enter vgchange -a y and then mount -a and then its perfect.

I still see this problem device-mapper 1.01.04 lvm2 2.01.13 baselayout 1.11.13-r1 Should this bug be reopened? What else could be the cause? I have to manually activate my volume groups in local.start.
