Supported Update Paths
For the supported update paths to FluidFS version 6.0, see the Dell Fluid File System Version 6 Support Matrix. This matrix is
available from dell.com/support.
Update Considerations
The internal storage reservation for the cluster-wide data reduction dictionary was increased to 20 GB for the entire cluster.
Performing Pre-Update Tasks
Complete the tasks in the following list before updating to the latest version of FluidFS version 6.0.
● Change the FluidFS cluster name and NetBIOS name to match.
Make sure the cluster name contains 15 or fewer characters and does not begin with a number.
● Delete local user names that have a period as the last character. Recreate these accounts with different names.
● Stop all NDMP backup sessions.
If an NDMP backup session is in progress during the update, the temporary NDMP snapshot is left in place.
● Open additional ports on your firewall to allow replication between replication partners.
● Make sure SMB shares and NFS exports have only alphanumeric characters in the Comment field.
● Make sure all the defined DNS servers are accessible using ping and dig (DNS lookup utility).
● Make sure the Active Directory domain controller is accessible using ping, and that the FluidFS cluster system time is in sync
with the Active Directory time.
● Make sure the NAS controllers are running, attached, and accessible using ping, SSH, and rsync.
Although only one NAS controller is required to be running in each NAS appliance, Dell recommends that all NAS controllers be
running.
