Update - also tested with 5.3.1, 22.214.171.124.
Stop and uninstall current 4.x version
service cvfs fullstop rpm -qa | grep -i snfs rpm -e snfs-server rpm -e snfs-client rpm -e snfs-common
Then install 5.x using rpm -ivh or -Uvh, Quantum instructions is missing the install of the snfs-server rpm! This should be installed after install the snfs-common rpm.
Using these Quantum documents as the guides, they are in the 5.2.0.zip from the Knowledge Base download (only available for internal staff).
Section: Upgrading HA Systems To StorNext 5 with .RPM Files, page 27.
Section: Installing StorNext File System-Only from RPMs, page 60
The guides are missing some steps, here is the updated and tested outline containing the pertinent steps.
This example tested with a 3u MDS, RHEL 6.2, upgrading from StorNext 4.2.2.
Quoting the guide: You can upgrade directly from StorNext 4.1 if you are using RPM files to upgrade the MDC.
It does not say StorNext 4.1 OR ABOVE, I will assume they meant that.
License and install file
Make sure you have a valid StorNext 5 license.dat before the upgrade, backup the previous license.dat file and put new one in place.
Copy and extract the .zip to folder in /usr/local/src/snfs/5.2.0, this is the default path where all software installs should live.
Change to the directory and expand the appropriate .bin, .rpm and related files are expanded to /tmp/stornext
cd /usr/loocal/src/snfs/5.2.0./ chmod 777 RedHat60AS_26x86_64_5.2.0_51843E.bin ./RedHat60AS_26x86_64_5.2.0_51843E.bin cd /tmp/stornext
The .cfgx gets updated, the original is backed up in /usr/cvfs/data/……. should you ever need to go back.
cd /tmp/stornext/stornext_full/RedHat60AS_26x86_64/DSM rpm -Uvh snupdate-<version>.rpm rpm -ivh quantum_protobuf-<version>.rpm rpm -ivh quantum_zeromq-<version>.rpm rpm -ivh quantum_jansson-2.4.0-2.x86_64.rpm rpm -ivh snfs-common<platform/revision>.rpm rpm -ivh snfs-server-<platform/revision>.rpm (for client installation, omit this) rpm -ivh snfs-client-<platform/revision>.rpm rpm -ivh snfs-compat-<version>.rpm
Verify and start
service cvfs start
The first time start after upgrade will take a little longer than normal at the
Waiting for CVFS mounts to complete.
