<font size=2 face="sans-serif">Right, Bryan. To expand on that a
bit, I'll make two additional points. (1) Only a node in the cluster
that owns the file system can be appointed a file system manager for the
file system. Nodes that remote mount the file system from other clusters
cannot be appointed the file system manager of the remote file system.
(2) A node need not have the manager designation (as seen in mmlscluster
output) to become a file system manager; nodes with the manager designation
are preferred, but one could use mmchmgr to assign the role to a non-manager
node (for instance).</font>

Based on my reading of the code, when a softQuotaExceeded event callback
is invoked with %quotaType having the value "FILESET", the following
arguments correspond with each other for filesetLimitExceeded and softQuotaExceeded:</font><font size=2 face="Calibri"><br>
</font><font size=2 face="Arial"><br>
- filesetLimitExceeded %inodeUsage and softQuotaExceeded %filesUsage<br>
- filesetLimitExceeded %inodeQuota and softQuotaExceeded %filesQuota<br>
- filesetLimitExceeded %inodeLimit and softQuotaExceeded %filesLimit<br>
- filesetLimitExceeded %filesetSize and softQuotaExceeded %blockUsage<br>
- filesetLimitExceeded %softLimit and softQuotaExceeded %blockQuota<br>
- filesetLimitExceeded %hardLimit and softQuotaExceeded %blockLimit</font><font size=2 face="Calibri"><br>
</font><font size=2 face="Arial"><br>
So, terms have changed to make them a little friendlier and to generalize
them. An inode is a file. Limits related to inodes and to blocks
are being reported.</font><font size=2 face="Calibri"><br>

We were looking at adding some callbacks to notify us when file-sets go<br>
over their inode limit by implementing it as a soft inode quota.<br>
<br>
In the docs:</font><font size=2 color=blue face="Calibri"><u><br>
</u></font><a href=https://www.ibm.com/support/knowledgecenter/en/STXKQY_4.2.3/com.ibm.spectru><font size=2 color=blue face="Courier New"><u>https://www.ibm.com/support/knowledgecenter/en/STXKQY_4.2.3/com.ibm.spectru</u></font></a><font size=2 face="Courier New"><br>
m.scale.v4r23.doc/bl1adm_mmaddcallback.htm#mmaddcallback__Table1<br>
<br>
<br>
There is an event filesetLimitExceeded, which has parameters: %inodeUsage<br>
%inodeQuota, however the docs say that we should instead use<br>
softQuotaExceeded as filesetLimitExceeded "It exists only for<br>
compatibility (and may be deleted in a future version); therefore, using<br>
softQuotaExceeded is recommended instead"<br>
<br>
However.<br>
<br>
softQuotaExceeded seems to have no %inodeQuota of %inodeUsage parameters.<br>
Is this a doc error or is there genuinely no way to get the<br>
inodeQuota/Usage with softQuotaExceeded? The same applies to passing<br>
%quotaEventType.<br>
<br>
<br>
Any suggestions?<br>
<br>
Simon<br>
