lvm problem ... can´t describe it shortely

Hello,
I am using 2.4.14 with lvm and xfs patched.

I used
/dev/hda2 [20GB]
/dev/hdb1 [8.5GB]
/dev/hdd1 [10,5GB]
/dev/sdb1 [9GB]
/dev/sdc1 [4,5GB]

In a volume group vg01 with 3 lv´s.

Now I added another SCSI disk as /dev/sdd5 to my system, created the partition with 8e type, did a "pvcreate /dev/sdd5", "vgextend vg01 /dev/sdd5", "pvmove /dev/sdc1 /dev/sdd5", "vgreduce vg01 /dev/sdc1". Same procedure with /dev/hdb1.

Then I shutdown my PC, removed the 2 disks and added a new IDE HD as /dev/hda2 [80GB]
/dev/hdb2 [the old /dev/hda2]
/dev/hdd1
/dev/sdb1
/dev/sdc5 [the new SCSI disk instead of the old one, was /dev/sdd5]

I rebooted and created a new pv with my new HD (/dev/hda3), created a new vg called store and a new lv called data. Then I copied all my data stored on a non-lvm volume (/dev/hdc1) to the new lvm drive (/dev/store/data), created a new pv (pvcreate /dev/hdc1), extended the vg store and extended the lv.

Now I want to activate my old vg01 and vgscan only finds the new volume group store.

I used uuid_fixer on every device
" uuid_fixer /dev/hdd1 /dev/hdb2 /dev/sdb1 /dev/sdc5 /dev/sdb1 - Success"

$# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/hdc1" of VG "store" [57.25 GB / 0 free] #correct
pvscan -- inactive PV "/dev/hdd1" is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/hda3" of VG "store" [76.07 GB / 0 free] #correct
pvscan -- inactive PV "/dev/hdb2" is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/sdb1" is in no VG [8.51 GB] #
pvscan -- inactive PV "/dev/sdc5" is associated to an unknown VG (run vgscan) pvscan -- total: 6 [187.49 GB] / in use: 5 [178.98 GB] / in no VG: 1 [8.51 GB]

vgscan still only finds the vg store, so I tryed to use vgcfgrestore to get my vg01 back:

$# vgcfgrestore -n vg01 -l
--- Volume group ---

VG Name               vg01
VG Access             read/write
VG Status             NOT available/resizable
VG #                  0
MAX LV                256
Cur LV                3
Open LV               0
MAX LV Size           255.99 GB
Max PV                256
Cur PV                4
Act PV                4
VG Size               53.51 GB
PE Size               4.00 MB
Total PE              13698
Alloc PE / Size       12583 / 49.15 GB
Free  PE / Size       1115 / 4.36 GB
VG UUID               p8KJS0-eei7-s10H-61hT-7uJS-Euiq-bXhlNs

This seems to be correct for me.
So I tryed the restore:

$# vgcfgrestore -f /etc/lvmconf/vg01.conf -n vg01 /dev/sdc5 vgcfgrestore -- physical volume "/dev/sdc5" doesn't belong to volume group "vg01"

$# vgcfgrestore -f /etc/lvmconf/vg01.conf -n vg01 /dev/sdb1 vgcfgrestore -- physical volume "/dev/sdb1" doesn't belong to volume group "vg01"

$# vgcfgrestore -f /etc/lvmconf/vg01.conf -n vg01 /dev/hdb2 vgcfgrestore -- physical volume "/dev/hdb2" doesn't belong to volume group "vg01"

$# vgcfgrestore -f /etc/lvmconf/vg01.conf -n vg01 /dev/hdd1 vgcfgrestore -- ERROR "vg_write(): open" storing VGDA of "vg01" on disks

Do you have any ideas what I can do?

vgscan scans drives in sequence. It takes the first drive mentioning a vg to get the list of pvs for that vg. If you have stale pv info on a drive that gets scanned early, you won't be able to activate the vg. I ran into this before.
I used pvdisplay on drives/partitions to see the info. Then I nuked the stale pv info.

	dd if=/dev/zero of=/dev/<pv> bs=512 count=1

does the trick.
Be careful not to run that on the whole disk, but on the partition if you have partitions, you'd loose them.
Be careful also not to run that on any current pv.
AFAIK IDE drives get scanned before SCSI drives, so old /dev/hdb1 might be the culprit.
You definitely should have no pv info on old /dev/sdc1 nor old /dev/hdb1 (Not sure what their names are now).
If pvdisplay on old, phased out pv, complains, you may want to try (assuming you run 1.0.1rc4):

	dd if=/dev/<pv> bs=512 count=1|od -c
If the output looks like
	0000000   H   M
	... (snip 5 lines)
	0000240   (snip 12 positions) v   g   0   1
	0000260   \0 (snip rest of line)

Then you need to nuke the pv info.
Still new to this, somebody correct me if I'm wrong.

Good luck,
Yves

Hello,
the problem is solved. I mistyped a command and removed the wrong disk. Sorry.
