Thanx ALL, yes i followed the procedure to fix the initrd and worked. thanx again. <div class="gmail_quote">On Thu, Apr 21, 2011 at 2:59 PM, Tom Combs <<a href="mailto:combs@fsu.edu">combs@fsu.edu</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div><div></div><div class="h5">On 04/21/2011 03:15 PM, Jonathan Smith wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> On 04/21/2011 11:10 AM, Rogelio Bazan wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> hi All, I have rhel4.7 with lvm2 lvm2-2.02.42-9.el4. At boot time, when trying to mount the file systems, it can't find the devices/lv's which are on a different volume group. I have 2 VG's one for the OS file systems vgroot and other for Applications File systems vgapps. Those lv's which are on vgapps, cannot be mounted because the vgapps is not being activated at boot time. Once OS is up, i can do vgchange -ay vgapps and mount -a. </blockquote> Check/rebuild your initrd. smithj _______________________________________________ rhn-users mailing list <a href="mailto:rhn-users@redhat.com" target="_blank">rhn-users@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/rhn-users" target="_blank">https://www.redhat.com/mailman/listinfo/rhn-users</a> </blockquote> </div></div> Yeah, sounds like your initrd is broken. I've had somewhat similar problems on RHEL4. For guidance, I've included a procedure I've used for fixing another issue with the initrd. Note that this is a different problem then what you are having but the steps for getting in a fixing the initrd will be similar, you just need to fix a different part. Hopefully this will be enough to point you in the right direction. Problem ======== On xxx, once after upgrading the kernel and once after installing vmwaretools, the initrd gets broken. On booting, this error is generated: Checking root filesystem [FAILED] /dev/VolGroup00/LogVol00 is mounted. e2fsck : cannot continue, aborting. *** An error occurred during the file system check *** Dropping you to a shell; blah, blah, blah The problem is that the init file in the initrd image mounts /root in read,write and then tries to e2fsck /root. This can't be done on a mounted file system, thus the error. This has only happened on xxx and is most likely an issue with RHEL 4. Solution ======== Boot the system using an older kernel (hit return on the boot screen before booting occurs, select older kernel, hit return). If you don't have an older kernel, you'll have to boot off of CD and go into rescue mode and the go to were the disk is mounted, /mnt/sysimg (?) When the system is up, fix the broken initrd image with the following. Note that the kernel levels used are for example and will probably differe from what you have. 1) mkdir /tmp/initrd 2) cd /tmp/initrd 3) gzip -dc /boot/initrd-2.6.9-89.0.18.ELsmp.img | cpio -id 4) vi init change mount -o rw,acl --ro -t ext3 /dev/root /sysroot to mount -o defaults --ro -t ext3 /dev/root /sysroot save changes 5) mv /boot/initrd-2.6.9-89.0.18.ELsmp.img \ /boot/initrd-2.6.9-89.0.18.ELsmp.img.orig 6) find ./ | cpio -H newc -o > /boot/initrd-new.img 7) gzip /boot/initrd-new.img 8) cd /boot 9) mv -v initrd-new.img.gz initrd-2.6.9-89.0.18.ELsmp.img (over write = yes) 10) reboot using the 2.6.9-89.0.18 kernel with the fixed initrd. -- Tom Combs Systems Administrator Information Technology Services Florida State University <a href="tel:%28850%29%20645-8026" value="+18506458026" target="_blank">(850) 645-8026</a> <a href="mailto:combs@fsu.edu" target="_blank">combs@fsu.edu</a><div><div></div><div class="h5"> _______________________________________________ rhn-users mailing list <a href="mailto:rhn-users@redhat.com" target="_blank">rhn-users@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/rhn-users" target="_blank">https://www.redhat.com/mailman/listinfo/rhn-users</a> </div></div></blockquote></div>
