Avamar: Linux backups complete with Exception with Avtar Error linuxsecurity init("/mnt/xx") llistxattr() failed

A new Common Internet File System (CIFS) share mount point was added to the dataset.

Avamar Linux backups complete with Exception with Avtar Errors. 

The following errors are seen in the client logs (/usr/local/avamar/var/clientlogs/):

The Errors coming from this partition: /mnt/xxxxx/bulletin/

The output of the "df -h" command shows that the mount point is a is CIFS share //storage-xxxxx/xxxxx-xxxxx  8.0E     0  8.0E   0% /mnt/xxxxxxxxx

The affected mount point appears to be a CIFS share which is causing the avtar issue.

To resolve this issue, perform one of the following steps:

1.The commended solution is to backup the CIFS shares at the source rather than the mount point:

• Remove this CIFS from the dataset.
• Backup the data at the source and exclude it from the backup list on the system.

2. Add the following switch to the avtar command to address the Access Control Lists (ACL):

--ignoreacls
