to set?</font><br><font size=3>HI All,<br></font><br><font size=3>We have a system where all users have their own private
group as well. However, for a given fileset (we are using --perfileset-quota),
we would like to ONLY allow users who also belong to just a few central
groups to be able to write to the fileset. <br><br>That is, user "userA" has its own "groupA", but we
only want the user to be able to write to the fileset if:</font><br><font size=3> - userA belongs to one of the groups (e.g. group1,
group2, group3) that have explicitly set quotas</font><br><font size=3> - The group(s) in question are within quota/limits.<br></font><br><font size=3>In general, we do not want any users that do NOT belong
to one of the three groups with enabled quotas to be able to write anything
at all to the fileset.<br></font><br><font size=3>Is there a way to set a ZERO quota for block/file in GPFS,
that means what it actually should mean? i.e. "Your limit is 0 file
= you cannot create files in this fileset". Creating some kind of
"supergroup" owner of the fileset (with entitled users as members
of the group) could work, but that will only work for *one* group. <br></font><br><font size=3>If we cannot set the block and file limits to zero, what
*are* the smallest block and fie limits? In GPFS 3.5, they seem to be 1760MB
for block. Is there a smallest quota for files? (blocksize is 16MB, which
will be reduced to 4MB probably, in a subsequent cluster).<br></font><br><font size=3>Many Thanks,</font><br><font size=3> Keith <br><br><br><br>-- <br>Keith D.
