Hello,

Did you modify the /etc/security/limits and did you create the fs with the
large file enabled option ? I suggest to create a fs with allocation group
size of 64 MB and 131072 bytes per i-node.

I don't know any other limitation for AIX to create big files, except the
limitation of something like 1 TB which is far from your 50 GB

Anyway, why don't you create smallers volumes ? It's not a real problem
with TSM

We have just added 288GB raid 5 disk space on an F50 running AIX 4.3.3
running TSM 4.1.1  we created 2 fs at 133 GB each, we have tried creating a
new tsm volume starting at 100gb up to 133gb and all have failed about half
way thru  saying there isn't enough space.

any thoughts or are their any limitations as to the size we can go?

thanks
Paul
