Hello, I made some changes to my LVM setup on my box and was surprised to
find that my volume group was gone when I turned on the computer this
afternoon. I don't know if this is a bug or if I did something wrong.
I'll try to list all the things that I did. I would appreciate if someone
could let me know if I did something wrong or if I uncovered a bug. I
would also appreciate if someone could tell me how I could correct this
problem.
I have a RedHat 6.2 system with kernel 2.4.2. I am using the lvm_mod
module directly from the 2.4.2 kernel. I am using the lvm-0_9-1 rpm.
I have a volume group called storage made up of two partitions /dev/hda5
and /dev/hdb1. Here is information about them:
[root@js /root]# pvdisplay /dev/hda5
--- Physical volume ---
PV Name /dev/hda5
VG Name storage
PV Size 20.49 GB / NOT usable 2.84 MB [LVM: 140 KB]
PV# 1
PV Status available
Allocatable yes (but full)
Cur LV 1
PE Size (KByte) 4096
Total PE 5246
Free PE 0
Allocated PE 5246
PV UUID dsQm1p-6sTR-Czku-d1eV-Wj6Y-R4al-QWVjA2
[root@js /root]# pvdisplay /dev/hdb1
--- Physical volume ---
PV Name /dev/hdb1
VG Name storage
PV Size 28.62 GB / NOT usable 3.7 MB [LVM: 149 KB]
PV# 2
PV Status available
Allocatable yes (but full)
Cur LV 1
PE Size (KByte) 4096
Total PE 7327
Free PE 0
Allocated PE 7327
PV UUID bsAfjN-20M6-tBcd-Zw1s-cb1B-SIO3-XktC1l
The physical volume /dev/hdb1 was 295 PE's smaller, so I extended it using
these commands:
umount /dev/storage/storage_lv
lvextend -l+295 /dev/storage/storage_lv
I then resized my ext2 file system:
resize2fs /dev/storage/storage_lv
mount /dev/storage/storage_lv /storage
This all worked great. When I turned off my computer, then turned it on
later, the volume group was gone.
When vgscan was run, it gave this output:
[root@js /root]# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- no volume groups found
I searched and found out about the vgcfgrestore command and I ran these
commands:
[root@js /root]# vgcfgrestore -n storage /dev/hda5
vgcfgrestore -- VGDA for "storage" successfully restored to physical
volume "/dev/hda5"
[root@js /root]# vgcfgrestore -n storage /dev/hdb1
vgcfgrestore -- VGDA for "storage" successfully restored to physical
volume "/dev/hdb1"
[root@js /root]# vgchange -ay
vgchange -- volume group "storage" successfully activated
Now my volume is back, but I'm afraid it will disappear if I run vgscan
again. I did the backup command to backup the configuration, but got
this:
root@js /root]# vgcfgbackup -v
vgcfgbackup -- finding all volume groups
vgcfgbackup -- volume group found: storage
vgcfgbackup -- locking logical volume manager
vgcfgbackup -- checking volume group name "storage"
vgcfgbackup -- checking existence of volume group "storage"
vgcfgbackup -- ERROR: volume group "storage" has an invalid number of
physical volumes
vgcfgbackup -- ERROR "vg_cfgbackup(): vg_check_exist" backing up volume
group "storage"
Any help fixing this would be greatly appreciated. This volume has 45.5GB
of data on it and I don't have a tape drive that big! I could restore it
if necessary, but really REALLY don't want to! :)
If this is a FAQ, please point me to the information. I searched and
couldn't find anything.
Thanks
Jay

Jay, this is a problem related to a previous version of 0.9.1
Please get the 0.9.1 Beta 6 tarball from www.sistina.com and follow the
instructions in the contained INSTALL and PATCHES/README to update your
LVM installation.
You might like to remove the rpm package before in order to avoid the wrong
LVM version in the rpm database.
Until you have successfully update your LVM configuration, stay with the
vgcfgrestore'd system and avoid running vgscan.
In general vgscan is not needed anyway in case you *didn't* change your
disk related hardware configuration.
BTW: you can use e2fsadm(8) contained in the LVM distribution to resize
a LV *and* the contained ext2 filesystem in a single step.

Heinz -- The LVM Guy --

I updated my system to Beta 6 and everything works fine if I don't run
vgscan. If I do run it, it wipes out the configuration data for my LV and
I have to do a restore to get it back.
Is this a bug in vgscan or is it a problem with my system? If it is a
problem with my system, can someone let me know how to fix it?
Thanks for the help!
Jay
