Re: lvextend

Hi,

Don't bother about the processes running on the filesystem since you have online JFS product installed. Just run the below commands to extend the filesystem.

#lvextend -L 32768 /dev/vg00/lv-oracle-u01
#fsadm -F vxfs -b 32768M /u01

#bdf /u01

In the examble we are extending the mount point u01 to 32GB total.

Best wishes,

Ganesh.

Re: lvextend

Hi,

It is not preferred to have data lv's on vg00 though nothing is blocking.

vg00 should be used for only operating system for better managablity
Best wishes,

Re: lvextend

Hi Ganasen

He needs to extend Filesystem by 32 Gig more,
so old+new (16+32) size is required not only new size
while lvextend.( may be typo ) :-)

Sanjeev

Re: lvextend

Urgent reply needed please.
I know one disk is removed from the VG. I think the problem I am facing is due to the strict allocation policy. How to overcome this now?

rc85odb2:/ # lvextend -L 32768 /dev/vg00/lv-oracle-u01
lvextend: Warning: couldn't query physical volume "/dev/dsk/c2t0d0s2":
The specified path does not correspond to physical volume attached to
this volume group
lvextend: Warning: couldn't query all of the physical volumes.
lvextend: Not enough free physical extents available.
Logical volume "/dev/vg00/lv-oracle-u01" could not be extended.
Failure possibly caused by strict allocation policy

Re: lvextend

As said earlier, as long the disk is missing you cannot extend it, because it want to mirror the LVOL to the missing disk.

Fix your missing disk problem and it will work.

Hope this helps!
Regards
Torsten.

Re: lvextend

Ah..Torsten thanks for responding... we intentionally removed ther disk a few days ago and presented it to the other vPar.
Now there is only this disk remaining.
Now I think I should break the mirror and tell the VG/LV that there is no mirror disk.
And then I should proceed with the lvextend.

Also, vgdisplay shows me the enough free PE.

Am I correct?
