s per my knowledge the hpux file systems are mostly of vxfs.
and this vxfs is linked with Journaled filesystems.
JFS versions vary from releases to releases.
I need some deep data about this [ its for my learning.. since I face frequent file system size related issuses from my end users.]
thnx for your help.
mean for example i need to confrin the given file system ,say /u01 will support large files?
if so what is the jfs version it is having?
{ I remember to check the /etc/defaults/fs]

Re: jfs version info
The fstab file will show it for example, fsadm too.
Hope this helps!

SolutionI guess all JFS versions supports "large files"but max limit varies & you need to mount the fs with the option as below.
fsadm -o largefiles
yes /etc/fstab will help for sure.
The following are Maximum file size of individual hp-ux operating system.
It depends on which system you are running.
Hope this will help ..limit has increased
much for later versions and OS series
HP-UX JFS Disk Layout Maximum Maximum
Release Version Version Supported File Supported File System

Re: jfs version info
# swlist -l product |grep -i jfs
should tell you whether online JFS is installed in your system or not.
# cat /etc/fstab - check largefiles supported or not
# refer man pages ( lot of information you can see)
