pb extend mirror lv

[Gerald_13]

Hi again,
I can't increase a mirror lv (with cluster.
the error is :
lvextend: Not enough free physical extents available.
Logical volume "/dev/vg01/lvol6" could not be extended.
Failure possibly caused by strict allocation policy

how can I increase this lv in a other disk and is it possible? (with sam, the lv is in DLVM mode)
thanks very much again!!!!

regards,

Gerald

If you created the volume with the following lvcreate command.

lvcreate -C y -n newvg01 /dev/vg01

You have an issue.

You will need to back up the data remove the logical volume, put it back and restore.

On a standard 11.11 install lvol6 is /tmp

This file usually doesn't need to be huge.

If you are doing an oracle install and it requires a 500 MB /tmp filesystem the install manual and the GUI has instructions on how to redirect temporary install files to a different filesystem. I think its by setting an environment variable.

Hi Gerald:

You probabably don't have enough free physical extents on one or more physical volumes to allow allocation of of mirror copies on separate volumes. Depending on your configuration you may need simply to specify the pv_name in your 'lvextend'. Too, you might be able to 'pvmove' extents scattered accross several disks onto one physical volume leaving another free for mirroring. See the man pages for more information.
