How to get large file systems in HPUX 11

[Rashid Hamid]

Hi all
I just want to know about vxfs file systems. As I know normal vxfs for one file size can go not more than 2GB. How to increase to maximum? and what is the maximum? As i know standard jfs in AIX 5L can support up to 64GB for one file . What about HPUX11. What are the method to use large file systems? Is it possible to specify large file system during installation?

Thanks in advance

You can convert a file system to use largefiles very simply using the fsadm command:

fsadm -o largefiles /dev/vg02/lvol1

For new file-system.

# /usr/sbin/mkfs -F vxfs largefiles ...

For changing the old file-system.

# /usr/sbin/fsadm -F vxfs -o largefiles ...

This is supported 10.20 & above.

Hi Rashid,

see my answer from thread http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=748474

max size is 1Tb for HPUX 11.x

Also don't forget to check ulimit.

You can use 'sam' to change a file system to support large files. Also, I think it the max is larger than a TB with 11.23PI. The max file is 2TB and max file system size is 32TB at the latest release. I think for 11.11 it is 2TB for both file size and file system size. Naturally, you can have more than one file system.
