Release Notes

Release Notes— Fluid Cache for SAN for Linux Systems
Use of Kpartx to Partition Volumes
ISSUE: When using the kpartx command to partition volumes, the partition table on shared
block devices is in an inconsistent state across the cluster. For instance, partitions created on a
LUN on one node may not be seen by other nodes.
WORKAROUND: Kpartx is not supported for partitioning a cached volume. Use the partprobe
command instead.
Syslog Error Messsages
ISSUE: The avahi-daemon writes numerous messages to syslog about receiving a packet from
an invalid interface when there is another mDNS stack (such as the one that Oracle RAC installs)
installed and running on the same node as Fluid Cache.
WORKAROUND: Move the other application’s mDNS stack to another node, if possible.
Otherwise, it is possible to patch and recompile the avahi-daemon to stop sending this
message. Contact Dell Customer Support for instructions on patching the avahi-daemon or to
obtain a replacement avahi-daemon.
Stopping the Fluid Cache Service Creates Segmentation Fault
ISSUE: On SLES 11 SP3, stopping the Fluid Cache service results in a segmentation fault because
of a conflict in the Avahi binary rpm.
WORKAROUND: Contact Dell Customer Support to obtain a patch with which to recompile the
Avahi binary rpm, or to obtain a pre-compiled version of the Avahi binary rpm. You may also
contact SLES to see whether a version of Avahi is available that is based on source version
0.6.24 or greater.
