Specific Subnet Clients Cannot Access The Powervault Nx3500 System; Strange Uid And Gid Numbers On Dell Nas System Files - Dell PowerVault NX3500 Administrator's Manual

Specific Subnet Clients Cannot Access the
PowerVault NX3500 System
Description Users (new or old), accessing from specific network(s), cannot
access the PowerVault NX3500 system.
Cause This issue is due to a conflict between the users' subnet addresses
and the NAS system internal network's address. The NAS system
routes the response packets to the wrong network.
Workaround
Strange UID and GID Numbers on Dell NAS
System Files
Description New files created from ubuntu 7.x clients get the UID and GID of
4294967294 (nfsnone).
Cause By default, ubuntu 7.x nfs clients do not specify rpc credentials on
their nfs calls. As a result, files created from these clients, by any
user, are owned by 4294967294 (nfsnone) UID and GID.
Workaround To force UNIX credentials on nfs calls, add the sec=sys option to
the PowerVault NX3500 mounts in the ubuntu fstab file.
Check the internal network addresses of the NAS system and
1
verify if there is a conflict with the problematic client network
addresses.
If a conflict exists, manually change the conflicting NAS internal
2
network address using either the NAS Manager or CLI.
