largefiles

jedd — Wed, 02 Jul 2003 17:21:22 GMT

hello everybody, i have configured a filesystem to support largefiles. well at least that what it says when i run fsadm- F vxfs /mount, it gives me a largefile result. i am running the base veritas on this /mount. my problem now is that i'm using this a diskbackup. it is exported to another box. should i export it with a certain option. the client server still cannot backup files over 2 GB size to the server where /mount is. to make it clear server0 with /mount with largefiles option is exported to server1. server1 tries to backup a 8GB DB, but cannot backup over 2 GB file size. any solution? thanks for all the help out there

Need to know your OS.

If its 11.00, you need a largefiles parameter in /etc/fstab

If its 11i such a parameter will be rejected at mount time.

Example.

/dev/vg01/utmp /utmp vxfs,suid,nolargefiles,delaylog,detainlog 0 2

Changes to
vxfs,suid,largefiles,delaylog,detainlog 0 2

Only for 11.00 though.

What utility are you using for a backup?

You mention that the filesystem is exported. Ensure you are using NFSv3 as NFSv2 only supports files up to 2Gb.

How are you transfering the files.

Neither tar nor any native tools support >2GB.

You can either use fbackup or get the GNU tar from

I think we still need to know what utility you use to make the backup before go further, and please confirm the tool used support >2G, such GNU tar, fbackup...

As someone has already mentioned you need NFS version 3 to support files over 2GB.
I believe that by default 10.20 is NFS version 2 and 11.00 is version 3.
To check NFS version:
# nfsstat -m on client
OR
# rpcinfo -p | grep nfs on server
(Shows available versions of NFS)

You don't need any specific export options to enable largefiles on NFS.

If you're running 11.00 on both systems then I'd be looking at the backup utility and its support for files over 2GB.

Hi,
HP-UX 10.20 comes with NFS Version 2 which doesn't support largefiles.
But 11.0 supports NFS Version 3 which supports largefiles.
Have a look at this url:
