UNIX Solaris

Hi guys.

We have filesystems resources taken from tha NAS nettap ; but the filesystem inside the solaris zone with some frecuency is unable.This filesystems are critical and we need constantly remount them.

Someone know if there are problems with the NFS resources in zones?

Where are the logs that save the reason of the issue ?.

Thanks in Advance.

ANGGAD.

How your NFS file system mounted? you can get the detail in /var/adm/message or dmesg

some thing like below

The following:
Zones and Containers FAQ at OpenSolaris.org
says that a non-global zone cannot be a NFS server, so it appears it is not supported.

The OP is having a non-global zone being a NFS client which is definitely supported.
