•
Offline Update (Recommended)
– This is the fastest option as all nodes are updated
simultaneously. The SnapScale will be offline (restarted) and unavailable during the
entire update process.
•
Online (or Rolling) Update
– This is a slower option as each node is updated in
sequence. The SnapScale will still be online and available during the entire update
process. However, performance will be reduced and some administrative features
will not be available. See
Online/Rolling Updates Notes on page 215
for caveats.
CAUTION:
With an Online/Rolling Update, all snapshots are deleted and your data has
reduced redundancy during the update.
After an upgrade and reboot, the
OS Update Status
page displays the success or failure of the
last update performed for each node.
