Resizing Partition in AIX

[ronfarris]

Hi Everyone!
Is it possible to resize the partition in aix without losing data. For instance when running the df command(which tells me space usage information), I see that on one partition I have 95% used space and on all of the others I have like, 14%, 45%, 65% etc. Is it possible to make the 95% usage partition larger by using the smaller partition's empty space. I thought I saw someone do this before, but I don't remember how he did it. I thought he was using smit.
Thank you in advance for your help.

ron,

Simply no.

You cannot decrease space in one filesystem and use it for another, once it is allocated you can if part of rootvg take a mksysb and restore selecting the shrink filesystem option to decrease the sizes or set up a new smaller filesystem and copy the data across and then change the mount points.

You can increase the size of a filesystems via the AIX dynamic kernel if you have free space via:

chfs -a size=<new size in 512 byte blocks> /filesystems

Thank you for the information. I thought I had seen someone do this before, but maybe not. Thank you again.

Try [tt]chfs -a size=+1 /filesysname[/tt], may be is what you want!

I hope it works...
