You didn't indicate that you updated your dasd= parameter in your parmfile and re-ran zipl. Take a look at this: http://linuxvm.org/info/howtos/mkinitrd-notes.html

My root file system and swap space are on unit 150e. I am using LVM to manage two other units 1611, and 1242 and I have /home, /var/and /opt filesystems mounted on volume group "system" in my /etc/fstab < snip > /dev/system/home /home reiserfs defaults 1 2 /dev/system/opt /opt reiserfs defaults 1 2 /dev/system/var /var reiserfs defaults 1 2 < snip > I am trying to extend the logical volumes assigned to /var, /home/ and /opt to get more space I was assigned a drive unit by my storage administrator, and I made sure the unit was varied offline on all LPARs I use the 'echo "add device range=113e" >>/proc/dasd/device' command to assign another unit to my system The "cat /proc/dasd/devices" shows the unit available. I ran dasdfmt, dasdfmt, and mkreiserfs, to prepare the new drive I ran "pvcreate /dev/dasdd1" sans quotes to create physical volume to LVM I ran "vgextend -v system /dev/dasdd1" sans quotes to get the disk defined to LVM I ran "lvextend /dev/system/opt +200" sans quotes to extend the file system (also ran it for /var and /home) I ran ""resize_reiserfs -f /dev/system/opt" to resize the filesystem (also ran it for /var and /home) When I ran df -k everything looks great until I cycle Linux, Then I receive the following message on the HMC and I cannot continue >>> Scanning for LVM volume groups... >>> lvm-mp: allocating 42 lowmem entries at 01316000 >>> LVM version 1.0.5+(mp-v6c)(22/07/2002) module loaded >>> vgscan -- reading all physical volumes (this may take a >>> while...) >>> vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of >>> volume group "system" from physical volume(s) >>> Unable to find swap-space signature >>> vgscan -- "/etc/lvmtab" and /etc/lvmtab.d" successfully created >>> vgscan -- WARNING: This is program does not do a VGDA backup of >>> your >>> volume group >>> Activating LVM volume groups... >>> vgchange -- no volume groups found >>> ..done >>> Activating swap-devices in /etc/fstab... >>> ..failed >>> Checking file systems... >>> fsck 1.28 (31-Aug-2002) >>> /dev/dasda1: clean, 82746/840320 files, 395657/1679988 blocks >>> fsck failed.

My attempts to run 'fsck' manually have not been successful. What I end up doing is doing a full image restore from backups I took before I tried to expand the filesystem and trying something else. Can someone point me in the right direction, or identify the step that I am missing.
