file size limit on HPUX 11.i

[massimo_38]

Hi everybody!

I'd like to know what is the file size limit on my hpux 11.i system.

Looking in the forum I found out this link

http://www.docs.hp.com/hpux/onlinedocs/5971-2383/5971-2383.html

And it tells me that 11.i with jfs supports 2TB file ONLY with version disk layout version 3 & 4.
Disk layout 2 supports 2Gb file instead.

So...how can I find out what disk layout version are we using?

If we don't support >2GB files...what can I do?

I read about the command
- fsadm -F vxfs -o largefiles mount point
but...should I reboot the system? should I loose the files on the filesystem or does the fsadm command do his work "on the fly"?

Thansk to anyone whop can help me!

Bye!

Hi,
Yes if you have online JFS then file's > 2GB are supported (upto 2TB) and you don't have to reboot the system for " fsadm -F vxfs -o largefiles mount point" command.
That will work on the fly.

Another question:

should I use the simple mountpoint or the raw device instead?

Thanks in advance!

Hi,

#fsadm -F vxfs -o largefiles /dev/vgnn/[r]filesystem

To know version and other activated options:
#fstyp -v /dev/vgnn/filesystem

f_flag: 16 indicates you that support large files!

Hi,

I have posted my answer here mistakenly, however there is a very light relationship with your question. There is not problem if points are not assigned.

Make sure that you also add the parameter in the /etc/fstab file...

Should look similar to:

/dev/vg15/lvol2 /mount_point vxfs largefiles,delaylog 0 2
