error trying to extend VG

NDO — Fri, 17 Jun 2011 06:33:08 GMT

Hi

I created VDISKS on EVA , present them to my server, then I sucessfully ioscan then: they are:
disk 136 0/4/2/1.2.2.0.0.0.5 sdisk CLAIMED DEVICE HP HSV200
/dev/dsk/c34t0d5 /dev/rdsk/c34t0d5

/dev/dsk/c34t1d1 /dev/rdsk/c34t1d1

I am tring to extend a VG I did the following:
mceldev[133]/ #umount /data1
mceldev[134]/ #pvcreate /dev/rdsk/c34t0d6
Physical volume "/dev/rdsk/c34t0d5" has been successfully created.
mceldev[135]/ #vgextend /dev/vg01 /dev/dsk/c34t0d6

this volume group
vgextend: Warning: couldn't query physical volume "/dev/dsk/c4t0d5":

and the list goes on... for more disks

So this is happening when I try to extend any disk apart from disk c34t0d5.

Please can you help

well my first question is whether the information supplied is correct:
mceldev[134]/ #pvcreate /dev/rdsk/c34t0d6
Physical volume "/dev/rdsk/c34t0d5" has been successfully created. <<<mceldev[135]/

Hi

Sorry, my mistake when copy and paste things, in fact initially when I did pvcreate for /dev/rdsk/c34t0d5 and /dev/rdsk/c34t0d6, all this commands were successfully runned, but when doing vgextend on disk c34t0d6 thats when I started to have those errors.

Sorry it was my mistake, I apologise

So compare now /etc/lvmtab with the output of vgdisplay -v vg01

I assume something has changed in the path, so some alternate paths are no longer there, but LVM complains about this. vgreduce -f could be an option.

Re: error trying to extend VG

NDO — Fri, 17 Jun 2011 11:14:08 GMT

Hi

vgreduce -f of what? disks or vg01? I have an old version of lvmtab, is that an option?

Fernando

Re: error trying to extend VG

NDO — Sun, 19 Jun 2011 15:33:07 GMT

Hi

what would be the impact of doing vgreduce -f /dev/vg01? Will I loose the disks/filesystems belonging to vg01? Because currently on vgdisplay -v /dev/vg01 I have 6 disks but on strings /etc/lvmtab and under vg01 I have lots of disks.

Please be nice to respond this post.

Fernando

Re: error trying to extend VG

NDO — Mon, 27 Jun 2011 07:16:58 GMT

Please can I have some inputs on this post:

I pvcreated the disk sucessfully, but when I try to vgextend, I get the following error:

this volume group

vgextend /dev/vg01 /dev/dsk/c34t0d6

vgextend: Warning: couldn't query physical volume "/dev/dsk/c4t0d4":

the specified path does not correspond to physical volume attached to this volume group.

And this message goes on and on for several other disks

So I did vgdisplay on the vg01, and this vg only came up 6 disks, but on strings /etc/lvmatb I have under vg01 almost 70 disks, so I decided to mv lvmtab to another file, them vgscan, but the newly created lvmtab has got again the same 70 disks.

So does the vgexport and vgimport will solve this problem? Please help

Re: error trying to extend VG

NDO — Fri, 01 Jul 2011 09:57:43 GMT

Hi I found a solution with the help of HP employee:

vgreduce -l all disks present in the warning given by vgdisplay, them I was able to lvextend logical volume.

regards

Fernando
