This looks good to me. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. This should be resolved in mkinitrd-5.1.19.6-56 . VERIFIED with mkinitrd-5.1.19.6-56
lvm.conf has:
tags { hosttags = 1 }
lvm_dhcp70-248.rhts.bos.redhat.com.conf has:
activation { volume_list=["VolGroup00", "@dhcp70-248.rhts.bos.redhat.com"]}
After running mkinitrd the system was able to boot into runlevel 3 without a kernel panic.
An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.

Description of problem: RHEL5 will no longer boot, because it will not be able to activate the root VG/LV, if lvm is configured to use host tags with the configuration below inside /etc/lvm/lvm.conf tags { host_tags = 1 } The problem happens because mkinitrd copies lvm.conf verbatim inside the initrd without parsing it properly. tags { host_tags = 1 } is not suitable inside initrd time even because hostname is not set. Version-Release number of selected component (if applicable): rhel 5.3 How reproducible: with lvm Steps to Reproduce: 1- Pick a pristine RHEL5 machine recently installed with a root filesystem on LVM 2- insert the configuration onto lvm.conf tags { host_tags = 1 } 3- create the file /etc/lvm/lvm_`hostname`.conf and add the activation entries in there: activation { volume_list=[ "VolGroup00", "@myhostname.localdomain"] } 4- Rebuild initrd mkinitrd -f /boot/initrd-`uname -r`.img `uname -r` 5- Reboot with new initrd 6- Notice a kernel panic because root vg was not activated. Actual results: kernel panic because root vg was not activated. Expected results: normal boot Additional info: A few options are available. 1- creating an lvm.conf from lvm dumpconfig lvm dumpconfig > initrd/etc/lvm/lvm.conf 2- Another option is to use lvm dumpconfig and cherry pick what is more suitable. lvm dumpconfig global > initrd/lvm/lvm.conf 3- Another option entirely is to bypass having lvm.conf inside the initrd/init and doing: # lvm vgscan --config 'devices{ filter = [ "a/mapper/", "r/.*/" ] }' # lvm vgchange -ay VolGroup00 --config 'devices{ filter = [ "a/mapper/", "r/.*/" ] }' This is similar to what is done in the article below: http://kbase.redhat.com/faq/docs/DOC-10146
