Tried to create a 167 gb file system on 11.0 N40000.
Error File too large.
Tried to create a 80 gb file system.

Hi
If I dont remember wrong there was a 128GB filesystem limit in 11.0 (with vxfs). I am quite sure I had larger filesystems then 80GB.

I'm guessing your getting this error in your vgcreate command ? If that's the case what actually happened is the default 4MB extent size is probably not enough to store the LVM data structure because you got such a huge number of physical extents that needs to be stored in the LVM data structure. Try to increase your pe_size in your vgcreate command .. start with 8 if it does not like it increase it to 16, 32, 64 and so on until it stop complaining (check man vgcreate)
# vgcreate -s 8 /dev/vgXX /dev/dsk/cXtYdZ

Answering the other question ..
Depending on your JFS version these are the limits ..
Version 3
- Supports 128GB FS and 128GB files on 10.20
- Supports 1TB FS and 1TB files on 11.0 & above
Version 4
- Supports 1TB FS and 1TB files on 11.0

Hello,

Look at this document.

You need to support largefiles in order to use the full 128Gb.

Robert,

Make sure if you're using SAM that you have the patch PHCO_23436. This is for the interaction between SAM and vxfs for the 1TB filesystem that S.K. mentioned.

HTH,

Dave
