64bit inodes and IA32 apps over NFS

[Lukas Hejtmanek <xhejtman@ics.muni.cz>]

Hello,

is there any workaround for NFSv4 when exporting XFS with 64bit inodes?

IA32 apps receives:
getdents(3, 0xb7571008, 1000)           =3D -1 EOVERFLOW (Value too lar=
ge for defined data type)

when compiling on x86_64, I got not error.

=46rom the XFS man page:
By default, with 32bit inodes, XFS places inodes only in the first 1TB =
of
a disk. If you have a disk with 100TB, all inodes will be stuck in the =
first
TB. This can lead to strange things like "disk full" when you still hav=
e
plenty space free, but there's no more place in the first TB to create =
a new
inode. Also, performance sucks.

To come around this, use the inode64 mount options for filesystems >1TB=
=2E
Inodes will then be placed in the location where their data is, minimiz=
ing
disk seeks.

Beware that some old programs might have problems reading 64bit inodes,
especially over NFS.


So, is there any workaround in NFS for IA32 apps?
