Increasing size of a filesytem
hi
Im using AIX4.3. Through smit I tried to increase the size of a directory. I changed 10,000 blocks more but finally i got 524288 blocks more. That is

before change : 12582912 blocks
I have tried for change: 12592912 blocks
then i execute smit.
But finally I got: 13107200 blocks

I cannot understand the proper reason. Can anyone describe me about the actual technique of changing size.

Thanks
suman

It is not exactly adding the amount of blocks/Kilobyte etc. you want. It is extending the FS (Filesystem) at least by the size of 1 full PP (physical partition).
You can see how big a PP is with "lsvg <vgname>" on the VG (Volume Group) where you FS resides. If I am correct, in your case PP size seems to be ~524288 blocks == 256 MB on that VG.

I thought I explained it. What did you not understand?

I strongly recommend reading up on it when working with AIX:
IBM developerWorks: Wikis - AIX - LVM
