largefiles problem

[Murat SULUHAN]

Hi

I created a new logical volume, and I run mkfs command as following

mkfs -F vxfs -o largefiles /dev/vg00/mylvol

and I mount this volume as following

mount -t vxfs -o largefiles /dev/vg00/mylvol /mymountdir

I export this dir via NFS to linux and I mount this directory from Linux but I cannot copy a file which is larger than 2GB from linux to that directory

Why this process fail?

what is the version of nfs that your using?

[T G Manikandan · Accepted solution]

Just do a rpcinfo -p|grep nfs

Make sure you are using NFS v3

NFS v2 does not support large files

In your /etc/rc.config.d/nfsconf

MOUNTD=VER3
MOUNT=VER3

Restart nfs

/sbin/init.d/nfs.server stop & start

Murat, 2gb is maximum filesize that HFS suppors,
Exist tunable parameter "ulimit".
This parameter is the size of the largest file write (in blk of 512 kb).
See also sfnolim, hfnolim, sfszlim, hfszlim.

Both your HP-UX system *and* your Linux system must run NFS ver 3 or you'll never be able to access or create large files over NFS.

I use newfs instead of mkfs.

I don't think that is the problem, but I believe my methodology is recommended.

I think Bill's got the problem nailed with the NFS version issue.


run nfsstat and see if it helps you diagnose the issue.

Hi Suluhan,
I recommand you exec compress command before copying a file.
Compress command makes a file smaller.

Good day~~

Hi all

I added the following lines to the
/etc/rc.config.d/nfsconf file and restart the nfsd and remount the filesystem

MOUNTD=VER3
MOUNT=VER3

And now I can create file larger than 2GB

Thank u so much
