VGimport data inconsistent

zafar.rizvi — Fri, 20 Apr 2007 01:46:41 GMT

I am exporting disk from our Primary node and its shows the new disk exported successfully in th map file but when i am trying to import it on another machine, it shows only the previous harddrive details, not showing new updated partition. Although i can can see it in the IOSCAN of disk.

i did the following steps on secondary node.
mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000
vgimport -s -m /tmp/lvm_map /dev/vg01

Anybody help or suggestion how to check why new disk not updated in the lvmtab after importing.

regards
Zafar

hello zafar,

my manpage notes, that the -s option requires the use of the options -p -v and -m and it requires an S800 Server.

Can you try agaiin, using all four options.

can you have a look at
'
#ll /dev/vg*/group
whether the minor ID 01 is really unique.

This are my first suggestions. I hope, this will help a little.

Bye
Ralf

Dear

Tx for your help.

I export it with -p option already and i am importing it with -v -s -m option but no success, I also try to use -p with these option but not found any entry of importing system in the lvmtab. when i import it with -v -s -m option, it show the package drive details but not the updated thing.

Can you specify the command option sequence or any other solution which i can use to troubleshoot the problem

regards
zafar

Hi,

what does this mean:

"not showing new updated partition"

Have you tried to re-create the lvmtab ?

#mv /etc/lvmtab /etc/lvmtab.old
#vgscan -v
-look for errors

#strings /etc/lvmtab

By partition, I assume you mean "logical volume".

Take a look at your map file:

# cat /tmp/lvm_map

You should see a VG identifier, and a list of logical volume names, assuming they are different from the default "lvol1, lvol2, etc..) Do all 5 show up there?
If not, then there may be something wrong with your source VG.

You can try doing a vgexport -p -v -m WITHOUT the shared option, and reimporting on the second node again WITHOUT the shared option, but buy specifying a list of device files. For example:

vgimport -v -m /tmp/vgxx.map vgxx /dev/dsk/cxtydz /dev/dsk/cxtydz
