Warning: couldn't query physical volume

[dictum9]

What does this mean?
I tried rebuilding /etc/lvmtab without success. The PV has been reduced from the VG. What else can I do?



biz:/etc#: vgdisplay -v vg00|more
vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c2t0d0":
The specified path does not correspond to physical volume attached to
this volume group
vgdisplay: Warning: couldn't query all of the physical volumes.

Also

ioscan -fnC disk
and diskinfo both look OK.

I am now running the "dd" test.

Hi:

Did you move the old 'lvmtab' aside before running 'vgscan'?, as:

# mv /etc/lvmtab /etc/lvmtab.old
# vgscan -v -a

It appears that you have a bad disk --- c2t0d0.

See if :

# diskinfo /dev/rdsk/c2t0d0

...returns a non-zero size (a good sign if yes' bad if the size is zero).

See if the physical disk shows errors:

# dd if=/dev/rdsk/c2t0d0 of=/dev/null bs=1024k

Regards!

Yes, I moved the file before vgscan.

ioscan, diskinfo and dd all look good thus far

(dd is still running)

[dictum9]

dd test passed without errors! What now?

[dictum9]

Things just get more interesting - now I am getting this, after vgscan -a


#: vgdisplay -v v00|more
vgdisplay: Volume group "/dev/v00" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "v00".

[dictum9]

Typo.... Never mind.

Still the same error about "couldn't query physical volume"

[James R. Ferguson]

Hi (again):

What event(s) led you to rebuilding the 'lvmtab' in the first place?

Regards!

I mirrored the filesystem using the standard Itanium mirroring instructions. I couldn't complete it and was getting errors about the mirror disk. I didn't save the original error.

[dictum9]

#: vgscan -a -v
vgscan: The physical volume "/dev/dsk/c2t0d0s2" is already recorded in the "/etc/lvmtab" file.
vgscan: The physical volume "/dev/dsk/c2t1d0s2" is already recorded in the "/etc/lvmtab" file.

Couldn't stat physical volume "/dev/dsk/c0t0d0":
Invalid argument
Physical Volume "/dev/dsk/c2t0d0s2" is not part of a Volume Group

vgscan: has no correspoding valid raw device file under /dev/rdsk.
Verification of unique LVM disk id on each disk in the volume group
/dev/vg00 failed.

Any other ideas what to do?

[Deoncia Grayson_1]

lets start from the beginning..
what does
vgdisplay -v vg00 shows? does it even show c2t0d0?

so if you do a strings /etc/lvmtab it actually shows c2t0d0 belonging to vg00? you did vgreduce of c2t0d0 from vg00, correct? did you try doing vgreduce -f c2t0d0 from vg00?

[dictum9]

It appears that

vgreduce -f vg00
rm /etc/lvmtab
vgscan -v

did the trick
