combine two vg spaces
Hello,
I'm a newbie on this AIX/Unix.
I'm trying to combine the space of /testing1/ to /testing2/, so that /testing2/ may have more space.
How do I accomplish this?
I guess I have to unmount /testing1/ from /apple26lv first...
but after that I'm not sure how this can be accomplished?

/dev/apple26lv 2097152 /testing1/
/dev/apple27lv 52428804 /testing2/

Any advise are helpful.

Thank you

In your post you mentioned that you were trying to combine spaces so I'm assuming that /testing1 and /testing2 are on different volume groups.

umount /testing1

varyoffvg </testing1 volume group>

exportvg </testing1 volume group>

extendvg </testing2 volume group> <hdisk(s) from /testing1 volume group>

chfs -a size='+<size of space in 512bytes>' /testing2

If you error out because your LV in /testing2 is MAX'ed out increase the MAX lv size by dividing the space from your /testing1 by the 'PP' size and increase by that amount.

That doesn't combine them, that deletes /testing1 completely and just extends the size of /testing2! Thats not what he's asking for and it results in complete data loss!
