zfs discuss - Apr 2007 - CAD application not working with zfs

Hello,

was use several cad applications and with one of those we have problems using
zfs.

OS and hardware is SunOS 5.10 Generic_118855-36, Fire X4200, the cad application
is catia v4.

There are several configuration and data files stored on the server and shared
via nfs to solaris and aix clients. The application is crashing on the aix
client except the server is sharing those files from a ufs filesystem. Has
anybody informations in this?

Regards.

What are the sizes of the filesystems being exported?  Perhaps the AIX
client cannot cope w/ large filesystems?

A snoop trace would be helpful to diagnosis this.  Do you know why  
the app on the AIX client is crashing (a particular error)?

Hello Basrt,

tanks for your answer. The filesystems on different projects are sized between
20 to 400 gb. Those filesystem sizes where no problem on earlier installation
(vxfs) and should not be a problem now. I can reproduce this error with the 20
gb filesystem.

Regards.

Are you using nfsv4 for the mount?  Or nfsv3?

Some idea of the failing app''s system calls just prior to failure
may yield the answer as to what''s causing the problem.  These
problems are usually mishandled error conditions...

Hello Bart,

we?re using nfsv3 by default but also tried version 2. There is no difference
between the two. Version 4 ist not possible with the aix 4.3.3 clients.
