which currently owns the resource actively journals the shared resourcewhile other journal services on workstations in the cluster which do notown the resource must defer journaling until the resource becomesavailable (or is moved to that workstation). The configuration settingsdeferFSMonStart, deferRetryInterval, and logFSErrors allows deferment for afile system until the file system is available and accessible.A value of 1 specifies that the journaled file system journal database is notdeleted when the journal file system goes offline. The database is also validwhen the journal file system comes back online. This value should be usedwith caution because any file system change activity which occurs whilethe journaled file system is offline is not reflected in the journal database.The default setting of 0 deletes the journaled file system journal database.Note: The journal is only preserved when a journaled file system comesoffline normally or is brought offline when the resource is no longeravailable and you specify the deferFsMonStart setting. If a file systemcomes offline due to an error such as a notification buffer overrun, thejournal is not preserved.An example for not deleting the journal database upon exit is:[JournaledFileSystemSettings.D:\];; Do not delete the journal when D:\ goes offline;PreserveDbOnExit=1deferFSMonStart settingThis setting defers an attempt to begin monitoring a file system in thefollowing cases:v When the specified journaled file system is not valid or availablev The journal directory for the specified journaled file system cannot beaccessed or createdResources are checked at the interval you specify using thedeferRetryInterval setting.The deferFSMonStart setting is most commonly used in a clusterenvironment where shared resources might move to different workstationsin the cluster.A value of 1 indicates that the setting is on. A value of 0 indicates that thesetting is off. The default value is off (set to 0) .deferRetryInterval settingThis setting specifies the value in seconds that a deferred file systems withthe deferRetryInterval setting enabled are checked for availability andbrought online. The default value is 1 second.logFSErrors settingThis setting specifies whether errors encountered while accessing ajournaled file system or journal directory are logged in thejbberror.logand the event log.Use the logFSErrors setting with the deferFSMonStart setting to preventexcessive File System unavailable messages from being logged whenbringing a journaled file system online is deferred. The first error whichcauses the file system to be deferred is logged. Subsequent errors are notlogged. A value of 1 indicates that the setting is on. A value of 0 indicatesthat the setting is off.Chapter 2. Configure the Tivoli Storage Manager client 37
