Release Notes— Fluid Cache for SAN for Linux Systems
Known Issues in Fluid Cache for SAN 2.0.0
The following are known issues in Fluid Cache for SAN 2.0.0
Removing a Server from a Cluster
ISSUE: If you try to remove a server from a cluster before shutting down the server, Enterprise
Manager displays a message saying that the action is not allowed.
WORKAROUND: Shut down the server: In Enterprise Manager, locate the server, right-click,
and select Shut Down. Then continue with the Deployment Guide procedure “Removing a
Server from a Cluster.”
Removing Multiple Servers from a Cluster
ISSUE: Under some circumstances, remove more than one server at a time from a cluster may
cause I/O to hang or data to be lost.
WORKAROUND: Avoid removing more than one server at a time from a cluster.
Shutting Down Multiple Servers from an FLDC cluster
ISSUE: Shutting down more than one server (host) from an FLDC cluster for maintenance
purposes may cause potential performance issues and data loss.
WORKAROUND: Dell recommends not shutting down multiple FLDC Cluster hosts at the same
time to perform the updates.
To add new hardware, update BIOS, firmware version, OS level patches, or driver version on an
FLDC cluster host, you must perform one of the following steps:
• Shut down a single FLDC Cluster host at a time and perform the updates
• Shut down the entire cluster during a scheduled maintenance period and perform the
updates
Replacing a Failed Node on a Three Node Cluster
ISSUE: If one of the nodes in a three node cluster fails, Enterprise Manager does not allow
removal of the failed node, and displays a message that removing the node would result in
fewer than the minimum of three nodes required. If the node is manually removed and
returned to an operational state, Enterprise Manager does not allow it to rejoin the cluster,
displaying a message that the node already belongs to the cluster.
