Extend Mirrored logical volume

Nedved — Wed, 01 Jun 2011 03:44:48 GMT

HI,

In my database vg i am having a dblv for 100 GB.

The physical volumes are presented from 2 storage and both or mirrored.

From storage 1 - 2*50 GB disks
From storage 2 - 2*50 GB disks

My dblv size is 100 GB and mirrored with the second storage disks.
Now i need to increase the lvsize 200 GB so my storage presented 4 disks each 2 storages.

Please tell me how to extend the lv to the storage 1 disks and mirror that to the storage 2 disks. in my system online JFS product also installed.

It would be helpful to know your OS version and the output of vgdisplay -v and lvdisplay -v of the items in question.

Question is if the lvol is striped or if there are some other specials - wait for your details.
