Administrator Guide

smbclient //<FluidFS_cluster_name>/<SMB_share> -U user%password -c ls
Workaround It is recommended that you use the NFS protocol interfaces to access the FluidFS cluster le system
from UNIX/Linux clients. To work around this issue:
1. Ensure that the administrator creates NFS exports to the same locations that you use to access
using SMB and connect to them using the mount command from UNIX/Linux clients.
2. Use NFS-based interfaces to access the FluidFS cluster. 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 les 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, les
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 FluidFS cluster mounts in the
Ubuntu fstab le.
Troubleshoot Networking Problems
This section contains probable causes of and solutions to common networking problems.
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 the FluidFS cluster subnet and verify that it responds.
2. Issue a request to the server from a client on the FluidFS cluster subnet and verify that it responds.
3. Check the server logs to see what is causing the server not to respond to requests.
Troubleshooting DNS Congurations
Description
Clients are unable to connect to the FluidFS cluster using the system name and/or unable to resolve host
names.
Cause Probable causes might be:
• Client IP address information is not set correctly.
• The FluidFS cluster is not congured to use the correct DNS server.
• DNS records are incorrect.
Workaround
1. Verify that the client IP address information is set correctly.
2. Verify that the FluidFS cluster is congured to use the correct DNS server.
3. Contact the DNS server administrator to verify the DNS record creation.
