Hi Every body,

I created Volume Group & FileSystem of type JFS2 with size 1.3 TB on AIX 5.2.
I want to import this VG on another system AIX 4.3. It is imported successfully & I can varyon the VG but unfourtantly I couldn't mount the FileSystem. Is it possible to mount a JFS2 FileSystem on AIX 4.3?

If it is not possible to do that, Is there any way to create a FileSystem with size 1.3 TB on AIX 4.3.

Thanks in Advance.

1: it's not possible to mmount jfs2 under AIX4.3

2: it is possible to generate a 1.3 TB FS on AIX 4.3, you can go till 2.199 TB

you need to set bytes per inode (NBPI) to 131072

jfs can handle 2^24 inodes, so you can have 2^24*131072 NBPI

Thank funksen,

I try to create filesystem with NBPI=131072, but when I invoke df -k I get the as below:
/dev/lv02 1073741820 1072617084 1% 17 1% /migdata

hm you are right, sorry

never tried this before, I've found out, that there is another limitation:

Fragment Size (bytes): 4096 * 2^28 which is 1T
