Subject: [NFS] NFS limits?

Hi all,
I've a 4246 GB (above 4TB) using NFSv2 to export it. Some application=20
are generating estrange errors, so it's possible I'm facing a NFS limit=
?=20
How large can a be to be exported without problems?

I'm using a 32bits architecture.

Thanks!
Jordi

NFSv2 is a 32 bit file access protocol, so don't be surprised
if you see EFBIG sorts of errors on operations such as FSSTAT.

In particular, that file system size is too large to represent,
I am sort of surprised that it would even be mountable.

Why not use NFSv3 or NFSv4?

Hi Peter,
My boss is reluctant to upgrade this server, so I'm stuck to NFSv2 :( I=

hope this will convince him !

Thanks,

You need NFSv3, at least. NFSv2 has various 2GiB limitations.
