HP StoreAll OS 6.5.1 Release Notes

for system::size for hardlinkA show the larger size, but requests for hardlinkB’s system::size
still report the old (smaller) size.
To find all hard linked files in a directory tree, enter the following command:
find <path> -links +1 -xtype f
Express Query treats soft links as “normal” paths. System metadata for the soft link is maintained
independently of the system metadata of the target. Custom metadata is also independent. You
can assign custom attributes to a soft link that differ from the custom attributes assigned to the
target of the link.
• The following Express Query audit event types are not yet audited when data validation scans
start and end, even when enabled.
◦ val_scan_started
◦ val_scan_ended
The audit event types are in place to support this functionality in the future.
• In the StoreAll REST API, the system::tier attribute is populated correctly when the file is first
created, or when it is first added to the metadata database if Express Query is enabled on an
existing file system. However, when the file system is moved to another tier by StoreAll file migration
utilities such as data tiering or rebalancer, that change does not yet update the system::tier
attribute available for query through the REST API.
• Root segment evacuation fails on a file system that has Express Query and retention enabled.
Before running segment evacuation, disable Express Query by entering the ibrix_archiving
–S command. You can re-enable Express Query after segment evacuation completes. To enable
Express Query, enter the ibrix_archiving –s command.
Failover
• If you need to make cluster configuration changes such as adding, extending, or deleting a file
system, be sure that at least two nodes in the cluster are UP and are not in nofmfailover mode.
If a configuration change is necessary and only one node is UP, save a copy of /usr/local/
ibrix/tmp/fmbackup.zip after each configuration change is completed. In the case where
only one node is UP, this copy can be used later if that node goes down before any of the other
nodes come up. In general, before you bring up cluster nodes that have been down for some
time, ensure that the cluster already has an active Fusion Manager running.
• When the active management console is moved to nofmfailover mode, a passive management
console will transition to active mode. Be sure that this transition is complete before you move the
previously active management console from nofmfailover mode to passive mode. (Use the
ibrix_fm -i command to check the mode of each management console.) If the passive
management console has not yet assumed active mode, the management console being moved
from nofmfailover to passive mode will become active again.
Fusion Manager
• In a cluster configuration, heavy load can impact the communication between nodes by increasing
the heartbeat response time and triggering failover. To avoid this issue, HP recommends that you
execute the ibrix_fm_tune commmand to increase the serverDownTimeout value based
on the load on the cluster. For example, change the value from 300sec to 500sec.
• The credentials management service (hpsp_credmgmt) will not allow adding a credential for a
new MSA storage array after the credential database is created. The workaround is to install the
credentials manually.
