getting error in vgimport

Madan Kumar — Tue, 17 Mar 2009 03:42:26 GMT

Hi all,

I had added disks in VG in a cluster environment, it was added successfully. But now when I try to import the vg information to adoptive node I am getting these error "# vgimport -p -v -s -m /tmp/vgxp_d01_ODSPD.map vgxp_d01_ODSPD

"Beginning the import process on Volume Group "vgxp_d01_ODSPD".
Verification of unique LVM disk id on each disk in the volume group
/dev/vgxp_d01_ODSPD failed.". Please help

thanks
madan

Hi Madan,

Example:-

On the other node:
1. Export the VG
>>>vgexport /dev/vgxx

2. Recreate the directory
>>>>mkdir -p /dev/vgxx

3. Recreate the VG group file
>>>mknod /dev/vgxx/group c 64 0xMM0000
where MM is a unique identifier (ex 01 for vg01)

4. Preview the vgimport to check for any possible error
>>>>vgimport -pvs -m /dev/vgxx
where mapfile is the one copied from the first node

5. If no error, remove the preview mode
>>>>vgimport -vs -m /dev/vgxx

6. Activate in share mode
>>>>vgchange -a s /dev/vgxx

Thanks,
Johnson

Hi ,

The minor number of the volume group "vgxp_d01_ODSPD" should be same on both the nodes .

Example :-

# ls -l /dev/vg01/group
crw-rw-rw- 1 root sys 64 0x010000 Nov 15 09:41 /dev/vg01/group
#

In the above volume group vg01 the minor is "0x010000" , .For proper sharing with the second node I should create a group file using "0x010000".

Thanks,
Aneesh

ioscan -fnC disk

Tks,

>>adoptive node <<

can you compare the "lvmtab" on both primary node and adoptive Node

# strings /etc/lvmtab

looks like your lvmtab , give problem,

# cp -p /etc/lvmtab /etc/lvmtab.org

run vgscan -pva first, then if required run vgscan -a. Also backup old file first.

Thanks,
Johnson

As suggested by Johnson , first check the /etc/lvmtab consistency using vgscan â pva and resolve the issues before proceeding to the vgimport steps.

Sample steps:-

Node 1:-

# ls -l /dev/vg02/group
crw-rw-rw- 1 root sys 64 0x020000 Nov 29 05:30 /dev/vg02/group
# vgexport -v -s -p -f /tmp/vg02.out -m /tmp/vg02.map vg02
Beginning the export process on Volume Group "vg02".
/dev/dsk/c4t0d2
# cat /tmp/vg02.out
/dev/dsk/c4t0d2
# cat /tmp/vg02.map
VGID 30a2e08949995b37

Copy the files /tmp/vg02.out and /tmp/vg02.map to the node 2 using ftp or scp .

Node 2:-

oprtest2:root:/ =>mkdir /dev/vg02
oprtest2:root:/ =>mknod /dev/vg02/group c 64 0x020000
oprtest2:root:/ =>vgimport -v -f /tmp/vg02.out -m /tmp/vg02.map vg02
Beginning the import process on Volume Group "vg02".
Volume group "/dev/vg02" has been successfully created.
Warning: A backup of this volume group may not exist on this machine.
Please remember to take a backup using the vgcfgbackup command after activating the volume group.
oprtest2:root:/ =>vgchange -a r vg02
Activated volume group
Volume group "vg02" has been successfully changed.
oprtest2:root:/ =>vgcfgbackup vg02
Volume Group configuration for /dev/vg02 has been saved in /etc/lvmconf/vg02.conf
oprtest2:root:/ =>

Hi Madan

You can try this also

#xd -j 8200 -N16 -tu (/dev/rdsk/c?t?d? ) do this for all disks in VG & Check if VGID is same in all disks.
