reduce space on filesystem to reallocate on other filesystem
I want to reduce space on filesystem to reallocate on other filesystem.
All the file system belongs to the sam volume group.

Re: reduce space on filesystem to reallocate on other filesystem
u mean u like to perform lvreduce? please bear in mind that lvreduce will "wipe out" all info from that logical volume.
or do u mean u like to do a rm first before mv to another file system?
regards.
(p.s. by the way, i believe u have not assign points for a number of posts)

Re: reduce space on filesystem to reallocate on other filesystem
If you have onlineJFS you can do this online by first reducing the filesystem with "fsadm". Then you reduce the logical volume wiht "lvreduce". Then increase the second logical volume with "lvextend" and then increase it's filesystem with "fsadm".
If you do not have onlineJFS then you can not decrease the filesystem even though you can reduce the logical volume. If, by chance, you have space at the end of you filesystem then you are OK. Otherwise, as Pete says, you need to recreate the logical volume and filesystem to the new size.

Re: reduce space on filesystem to reallocate on other filesystem
Is this filesystem you want to reduce on maybe in the same volume group as the one you want to add to...???
Maybe you could look at doing pvmove to simply move the data on one lvol (in first fs) to another lvol (in second fs).
Just a thought, may not apply in your case...but you never know...
Rgrds,
Rita

Re: reduce space on filesystem to reallocate on other filesystem
fsadm -F vxfs -d -D -e -E /mountpoint
then fsadm -b
then lvreduce -L
