Couldnt Querry Volume "." in LVM

Hi,

I am getting the following error before the vg/lvdisplay output.

Couldn't querry volume ".". The specified path doesnt corresponding to pv attached to this volume group.

But the pvdisplay and vgdisplay outputs are satisfactory, all volumes and mirrors are ok.


the lvmtab is also proper only.

But vgcfgbackup command is failing with an error.

/etc/lvmtab is out of date with the running kernel. Kernel indicates 3 disks for /dev/vg02; /etc/lvmtab has 2 disks.

I have tried vgscan also.

Please get your valuable suggestions..

Jaison.

Re: Couldnt Querry Volume "." in LVM

How many disks are supposed to be in vg02?

The kernel knows of three disks, but /etc/lvmtab knows of only two disks.

If only two disks should be there, use vgexport -m to create a map, and vgimport, specifying the correct two disk names.

See the man page for correct syntax.

Re: Couldnt Querry Volume "." in LVM

I would do something like this:
Try going to /etc/lvmconf.

strings vg02.conf ( Just consider latest file, what is the date this is created). If this is latest, see what disks it mentions. If you see three disks.

pvdisplay -v , if it says they belong to vg02.

cp /etc/lvmtab /etc/lvmtab.`date +'%m%d%Y'`
vgscan -p -v >> /tmp/vgscan$$
study the above file, if you feel satisfied, do the vgscan.
then do vgcfgbackup -u /dev/vg02.

Hope the above helps in getting to resolution

Thanks

Re: Couldnt Querry Volume "." in LVM

Thank you friends,

The VG is supposed to have only two disks, which are mensioned in lvmtab. that means the current lvmtab is right. (this is a new one I have created by a new vgscan).

I have tried vgreduce -f also.

now the thing remaining is vgexport and vgimport. the HP Document id: KBRC00000632
also stating it as a right procedure. Once I get a downtime, I will try and update you all..

Thanks,

Jaison.
