Extending filesystems

UNIX AIX

Hi to all

i want to increase the /usr size.
but, it is mirrored on hdisk0 and hdisk1.

i know that chfs will work, but i am not confident about mirroring.

can anyone tell me the procedure.

thanks

"chfs" will automatically take into account if the filesystem is mirrored or not and where to claim the PPs for the extension of the LV. It will also honor the set inter-policy and intra-policy of the LV. In this respect you have nothing to fear.

If you want more control abot where the additional PPs are being placed you can use "extendlv" first to resize the the LV and only then use "chfs" to grow the FS. (When calling chfs alone it does the same automatically using defaults for extendlv.)

For a detailed description of the process you might want to read this and this.

I hope this helps.
