NFS Question

Karen Pelosi_1 — Wed, 05 Jul 2006 04:27:09 GMT

I have a 5TB filesystem I've crossmounted on N4000 HP11.00 system and although it mounts o.k, bdf shows it as a 2TB file system.

HPUX 11
panasas1:/pan1 2147483647 2147483647 2147483647 42% /auto/panasas1/pan1

Linux
panasas1:/pan1 5078125000 2156743232 2921381768 43% /auto/panasas1/pan1

Does anyone know if HPUX supports file systems above 2TB?
Thanks,
Karen.

Shalom,

HP-UX supports filesystems up to 128 TB.

NFS may need to be upgraded on the server to support more than 2 TB. I don't recall 2 TB being an important number, like 2 GB is.

Hopefully NFS for 11.00 can be upgraded to support this.

We are using NFS v3 and have the latest NFS patches installed. Just seems very strange the bdf display is incorrect.

how does following look like?

mount -p

What options the nfs mount has been mounted with?

From http://docs.hp.com/en/1435/NFSPerformanceTuninginHP-UX11.0and11iSystems.pdf

The max file size supported from nfs client in nfs pv3 is 2TB for 11i, 1TB for 11.0. (2GB for nfs pv2).

mount -p shows
/etc/auto.local /auto/panasas1/pan1 autofs ignore,direct,rw,bg,intr,suid,timeo=50,rsize=32768,rsize=32768,tcp 0 0

It makes no difference if it's hard mounted or not. All our HP systems display the incorrect values.
