Release Notes

Release Notes— Fluid Cache for SAN for Linux Systems
Root File System Fills Up
ISSUE: Fluid Cache may fail and require manual intervention if the root file system on a node
becomes full. The cluster may still be operational, but error messages are generated and Fluid
Cache is not fully functional.
WORKAROUND: Please contact Dell Customer Support for the steps required to return the
node to full functionality.
Configuration Errors after Mapping Volume Fails
ISSUE: When mapping a volume to a Fluid Cache node, if the operation times out or fails to
complete normally, under some circumstances a partial configuration is created on the node,
and Enterprise Manager mistakenly shows an apparently normal volume mapping. When the
mapping is later completed normally, this partial configuration remains, and may interfere with
administrative actions. For instance, deleting the cluster may fail because Storage Center has a
record of a volume still in use by the cluster.
WORKAROUND: Contact Dell Customer Support for assistance in resolving this issue.
Timeouts on PowerEdge R820 Servers
ISSUE: On SLES 11 SP3, under some circumstances, I/O loads could cause CPU usage spikes that
decrease performance on PowerEdge R820 Servers.
WORKAROUND: None available.
GPT Partition Table Corruption
ISSUE: Partprobe reports GUID Partition Table (GPT) corruption and device mapper errors on all
other nodes after making partition table changes to cached LUNs on one node.
WORKAROUND: Do not modify partition tables on cached LUNs. Modifying partition tables on
shared volumes is not supported.
