Dell PowerVault NX3600 - Manual (Page 88)

Problematic SMB Access From A Linux Client
Description A Linux/UNIX client is trying to mount a NAS cluster
solution share using SMB (using /etc/fstab or directly
using smbmount).
A Linux/UNIX client is trying to access the file system
using the smbclient command, such as:
smbclient /// -U user
%password -c ls
Workaround It is recommended that you use the NFS protocol
interfaces to access the NAS cluster solution FluidFS
systems from Linux/UNIX clients. To workaround this
issue:
1. Ensure that your admin creates NFS exports to same
locations that you use to access using CIFS and
connect to them using mount command from Linux/
UNIX clients.
2. Use NFS based interfaces to access the NAS cluster
solution. For example, from the NAGIOS Linux
management system, use the /check_disk
command instead of the /check_disk_smb
command.
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 NAS cluster solution mounts in the Ubuntu
fstab file.
Troubleshooting Networking Issues
Name Server Unresponsive
Description All NIS, LDAP, or DNS servers are unreachable or not
responding.
Workaround For each server:
1. Ping the server from a client on NAS cluster solution
subnet and verify it responds.
2. Issue a request to the server from a client on the
NAS cluster solution subnet and verify it responds.
3. Check server logs to see what causes the server not
to respond to requests.
