2.4.3. Upgrading from Version 2.5

Version 2.5 Red Hat installations can upgrade to 2.6 by stopping all services, installing the new

version and then restarting services. After copying the 2.6 distribution file to the server and

unzipping it, run the following commands as root:

Note

Any configuration file backups previously taken for disaster recovery purposes must be

discarded and a new backup taken, as previous configuration files are not compatible

with the new software version.

Stop all client activity on the server. Stopping remote Samba or NFS access to the share is an

easy way to do this.

Monitor the local spooler cache draining to zero by using the following script:

./cfs-checkspool

The script will monitor the spool cache and any active writes for all configured shares in a loop

and print a statement when all activity has completed and it is safe to shutdown CFS.

Stop CFS: /etc/init.d/caringo-cfs stop

Stop CNS: /etc/init.d/caringo-cns stop

Install the new software: ./installCFS.sh

Start CNS: /etc/init.d/caringo-cns start

Start CFS: /etc/init.d/caringo-cfs start

2.5. Removing CFS and CNS

The following commands should be run to remove CNS and CFS if the data and metadata are no

longer needed:

Prior to removing CFS, the timescape horizon for all shares should be set to 0 days and then

all files and folders should be manually deleted from all mountpoints to ensure content is not

orphaned in DX Storage. This will trigger the namespace garbage collection process to delete

the associated content from DX Storage. When the CNS log at debug level consistently shows

that no files have been deleted as part of the garbage collection process, it is safe to proceed

with removal of the software.

Stop CFS: /etc/init.d/caringo-cfs stop

Stop CNS: /etc/init.d/caringo-cns stop

To remove all mounts, do the following for each mount: cfs-admin mkfs --delete --

cfs-id=testMount1 (where 'testMount1' equals the name of the mountpoint to be deleted)

Purge CFS code: yum remove caringo-cfs

Note

Removing CFS without first unmounting will not succeed and will print a scriptlet error

to the command line. Due to a defect in the Red Hat 6 package manager (yum) a more
