To modify file metadata synchronization settings:
1.In the Synchronize File Security Information section, select when you want the metadata replicated (you can select the first or second options, or both):
•Enable synchronizing file security information in real-time - Select this option if you want the metadata replicated in real-time. If enabled, changes to the selected access controls (Owner, Group, Linux Permissions, and ACL) will be transferred to the target host file(s) as they occur.
•Enable synchronizing file security information with master host during initial scan - Select this option if you want the metadata replicated during the initial scan. If enabled, changes to the selected access controls (Owner, Group, Linux Permissions, and ACL) will be synchronized during the initial scan.
Note: Nutanix does not support Access Control Lists (ACL) in the Network File System (NFS) version 4 (NFSv4) or POSIX formats.
2.If you selected either of the first two options in the Synchronize File Security Information section, click OK in the message that appears.
3.Select Enable prevention or corrupt or blank Owner or ACLS on source or master host from being applied to any target host if you want to ensure that if there are any issues with the ownership or ACLs on the source or master host (such as corruption or being blank), these issues will not propagate to the target host. Instead, the replication process will either skip or correct these problematic ownership or ACL entries to maintain data integrity and security on the target host.
4.Select the access controls (Owner, Group, Linux Permissions, and ACL) to be synchronized.
Note: To synchronize Owner or ACLs, the user that a Peer Agent service is run under on each participating host must have permission to read and write Owner and ACLs.
5.If you selected the option for metadata synchronization during the initial scan, in the Metadata Conflict Resolution section, select the host to be used as the master host in case of file metadata conflict. This option is only available when both of the first two options in the Synchronize File Security Information section are enabled, and Owner is selected under Synchronize Security and ACL Options.
If a master host is not selected, then no metadata synchronization will be performed during the initial scan. If one or more security descriptors do not match across participants during the initial scan, conflict resolution will use permissions from the designated master host as the winner. If the file does not exist on the designated master host, a winner will be randomly picked from the other participants.
6.Select Enable enhanced metadata conflict resolution if you want to prevent the Peer Agent service account from being assigned as the owner of that file or folder when a metadata conflict occurs, and a file or folder is written to a target. If the Peer Agent service account were to be assigned as the owner, the user may not have permission to access the file or folder.
Note: The Peer Agent service account cannot be a local or system administrator. As described in Peer Global File Service - Environmental Requirements, the Peer agent service account should be an actual user.
7.In the File Timestamps Transfer section, select Use source last accessed time if you want to preserve the last accessed time of the source file during the transfer process. This option ensures that the destination file inherits the same last accessed time as the source file after the transfer is complete.
8.Click OK to close the Edit wizard or select another configuration item to modify.
