NFS filesizes in 10.20

Hi!
What is the max filesize for a NFS filesystem in 10.20?

and is ftp affected by these limitations-- ..can ftp transfer files > 2GB

Re: NFS filesizes in 10.20

Both 9.X and 10.X NFS clients can mount filesystems
larger than 4Gb and are supported by HP. This is
documented in the Release Notes for 10.10:

Large File Systems
------------------

For 10.10, the maximum size of HFS and JFS file systems has
been increased from 4 Gb to 128 Gb. (The maximum size of
files continues to be 2 Gb.)

Large file systems can be exported through NFS to other
clients, who are be on any other supported version of HP-UX.
NFS clients do not have to be on 10.10 to read/write an
exported file system. For example, a 10.10 server can
export a 20 Gb file system to 9.x clients through NFS and
each of the clients can read/write to the 20 Gb file
system. Non-HP NFS clients can also access an LFS on an
HP server.

The filesize limitation is therefore, specific to the client.
A 9.X client cannot create a file larger than 2Gb. In fact,
even a 10.20 NFS client cannot create a file larger than 2Gb
over an NFS mountpoint. A 10.20 system can create a local
file as large as 128Gb, but NFS large file support is not
available.

HP Only Info

NFS version 3 will now allow an HP-UX 10.30 (or higher)
system to create and access files as large as 128Gb on an
NFS mounted filesystem.

I have not encountered any size limitations on my servers, but nfs and ftp. It is just that ftp takes very long time to get through and hugs your network traffic.

As to ftp ....I think at HP-UX 10.20 ftp does support large file systems so yes it will be able to cope.

This is just a reminder that Release Notes can be found under /usr/share/doc

There is also numerous other useful and interesting white papers and documentation regarding NFS, patches, euro, sendmail, etc.
