Administrator Guide

• Ensure the client VIP is specied in the backup job.
• Check if a recent delete of a big volume (TB) was executed. If so, wait for some time and retry the activity.
Troubleshooting an NDMP Internal Error
Description Backup or restore fails with an internal error.
Cause NDMP internal errors are indicators of a le system not being accessible or a NAS volume not being available.
Workaround If the backup application cannot connect to a FluidFS cluster:
1 Verify that NDMP is enabled.
2 Verify that the backup application IP address is congured in NDMP.
If the backup appliance can connect to a FluidFS cluster, but cannot log in:
1 Use the default user name “backup_user” congured in Storage Manager for the NDMP client while
setting up the NDMP backup/restore in your backup application.
2 Use the password congured in Storage Manager for the NDMP client while setting up the NDMP
backup/restore in your backup application.
If the backup application can log into the FluidFS cluster, but no NAS volumes are available for backup, verify
that the FluidFS cluster has NAS volumes created on it.
Troubleshoot SMB Issues
This section contains probable causes of and solutions to common SMB problems.
Access to SMB File Denied Due to Unavailable AV Server
Description
When a le on an SMB share is opened by a client application, the FluidFS cluster sends the le to an anti-
virus server to be scanned.
If no anti-virus server is available, access to the le and to the whole SMB share is disallowed.
Cause Because the anti-virus servers are not available on the FluidFS cluster, les cannot be opened on an anti-virus
enabled SMB share.
Workaround Ensure that the problem appears only on anti-virus enabled SMB shares, while clients accessing other SMB
shares do not experience such problems.
Check the status of the anti-virus servers and the network path between the FluidFS cluster and the anti-
virus servers.
Access to SMB File/Folder Denied Due to Permissions
Description
SMB access to a le or folder is denied.
Cause A client without sucient permissions performs an operation on a le/folder.
Workaround Check the permissions on the le/folder and set the required permissions.
SMB ACL Corruption
Description
SMB ACLs are corrupt.
Cause
• ACLs were accidentally changed by a user or script.
