Fadia Almarei — Tue, 01 Nov 2005 15:41:34 GMT

Dear All
when i try to extend my logical volume i get the following error
"The command used to extend logical volumes, /sbin/lvextend, has ^
failed. The stderr output from the command is shown below. The
logical volume has not been extended.

lvextend: Warning: couldn't query physical volume "/dev/dsk/c4t12d0":
The specified path does not correspond to physical volume attached to

this volume group
lvextend: Warning: couldn't query all of the physical volumes.
lvlnboot: Warning: couldn't query physical volume "/dev/dsk/c4t12d0":
The specified path does not correspond to physical volume attached to

this volume group
lvlnboot: Warning: couldn't query all of the physical volumes.
vgcfgbackup: Warning: couldn't query physical volume
"/dev/dsk/c4t12d0":"
what is the cause and solution for this problem.

Hi:

It sounds like the physical disk may not be viable. Do:

# dd if=/dev/rdsk/c4t12d0 of=/dev/null bs=1k count=10

Regards!

Fadia:
It appears that your disk c4t12d0 may be offline. You can check by running an ioscan -fnC disk to verify that the disk is claimed. If it is, try a diskinfo -v /dev/rdsk/c4t12d0 for infomation about the disk.

Did you just add the disk to the box? you may need to do a insf -e and a pvcreate if you just added the disk.

more info please...

Hi Fadia

Looks like there is some issue with the disk "/dev/dsk/c4t12d0":
you can run a diskinfo on that
#diskinfo /dev/rdsk/c4t12d0 and check you can also run a pvdisplay and see what it returns if this was not added you need to do a pvcreate..if that fails and still the disk is online and if you are sure that this disk in not used anywhere else you can do a pvcreate -f (make sure bware ***)

the amazing thing that the vg01 that u02 found in does not have this disk on it and this disk is unused,but why this happened i do not know ,another thing that the logical volume increase but the used size still the same ,i try to do extenfs command to this file system and then i intarupt it i try then to mount it it does not work i do the fsck command and it give me the following error;
#
# fsck /dev/vg01/ru02
vxfs fsck: invalid device config entry found

#
another problem

Hi,

This shall not happen unless the VG has been extended to this disk. For the LVOL and the file system part what does the "vgdisplay -v /dev/vg01" and "lvdisplay -v /dev/vg01/lvol1" say ?

Also post "strings /etc/lvmtab"?

HTH,
Devender

Try vgchange -a y /dev/vg01 and then see if the problem still persists
