Problem extending lvol7 in VG00

[Feljav]

When I tried to extend the lvol7, I get the following error:

lvextend -L 4000 /dev/vg00/lvol7
lvextend: Warning: couldn't query physical volume "/dev/dsk/c3t6d0":

lvextend: Warning: couldn't query all of the physical volumes.
lvextend: Not enough free physical extents available.
Logical volume "/dev/vg00/lvol7" could not be extended.
Failure possibly caused by strict allocation policy

When I run vgdisplay -v vg00:

Any help please!!!

Hi,

looks like the disk /dev/dsk/c3t6d0 has failed. Fix this first.


Refer to
http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad.pdf
on how to proceed.

[Geoff Wild]

Well - it looks like you have lost /dev/dsk/c3t6d0

Try

diskinfo /dev/rdsk/c3t6d0

Come back?

How about ioscan -fnC disk

Get any NO_HW ?

Rgds...Geoff

[Berd]

Feljav,

It looks like you may have a failed disk. Use ioscan to see if you can still see /dev/dsk/c0t6d0.

If it is showing as NO HARDWARE then you will need to place a hardware call.

Regards,
Berd

[Feljav]

Whe I run a ioscan -fnC disk I get HW path and the status is claimed.
/dev/dsk/c0t6d0
/dev/dsk/c3t6d0

[Feljav]

Any other help!!!

I run
dd if=/dev/rdsk/c3t6d0 of=/dev/null bs=1024k count=64 and everything is ok.

I run ioscan and diskinfo and everything is ok. Any help!!

[John Waller · Accepted solution]

Just because an ioscan shows the disk as CLAIMED it doesn't mean it is good. Sometimes the electronics and disk controller are working but the disk itself has stopped spinning. A diskinfo -v command or check the /var/adm/syslog/syslog.log file for any EMS errors or LVM errors.

As for your lvextend command the reason you can't extend is because you have a strict allocation policy set and have additonal lvols on the disk after lvol7. Top get around this you will have to remove the extra lvols or I think a lvchange -s n /dev/vg00/lvol7 might fix the problem but I've never used this method before as I always try to keep all my lvols in vg00 contiguous.

[Torsten.]

If the status is CLAIMED and dd works, try to
vgchange -a y vg00
vgsync vg00
and check the status again.

[Court Campbell]

try

# lvextend -L 4000M /dev/vg00/lvol7

Also you might want to look to see if you have any lvols with data on /dev/dsk/c3t6d0. You can use lvdisplay to see that info. If you do not have any extents used on that drive for any of the lvols you can remove it from the volume group. Then you can look into the issue you have with that disk. I hope you have a backup of the data in vg00.

[Feljav]

Court, How Can I see that?

[Torsten.]

I'm not sure what you did and if this was supposed to be done.

Once you get the disk back and synced, you will probably have lvol1 to lvol8 mirrored, but the other lvols are not mirrored:

LV Name /dev/vg00/lvol11
LV Status available/syncd
LV Size (Mbytes) 1000
Current LE 125
Allocated PE 125
Used PV 0 ___!!!!!

Please post also
lvdisplay -v /dev/vg00/lvol7
(without all the extend information).

[Mridul Shrivastava]

There are two possibilities:

1. disk is dead.. but you have mentioned disk is fine and there are no hw issues on that.

2. someone has done pvcreate -f on that disk. If this is the case then you have to either bring down the system in lvm maintenace mode and restore the vg configuration then reboot... else you need to lvreduce and vgreduce the disk using the Key value and extend the vg and lv once again..

[Geoff Wild]

Yes - lvols 9, 10, 11 are in trouble...

Are they mounted? If yes - any data in them?

Do you have a good backup?

Rgds...Geoff

if the disk is showing CLAIMED in ioscan; then do the dd for that disk.
Definitely the disk has issue.
Thanks,
Vivek
