<p><span style="font-size:12.0pt;color:black">Hi,<o:p></o:p></span></p>
<p><span style="font-size:12.0pt;color:black"><o:p> </o:p></span></p>
<p><span style="font-size:12.0pt;color:black">I have a filesystem holding many projects (i.e., mounted under /projects), each project is managed with filesets.
<o:p></o:p></span></p>
<p><span style="font-size:12.0pt;color:black">I have a new big project which should be placed on a separate filesystem (blocksize, replication policy, etc. will be different, and subprojects of it will be managed with filesets). Ideally, this filesystem should
be mounted in /projects/newproject.<o:p></o:p></span></p>
<p><span style="font-size:12.0pt;color:black"><o:p> </o:p></span></p>
<p><span style="font-size:12.0pt;color:black">Technically, mounting a filesystem on top of an existing filesystem should be possible, but, is this discouraged for any reason? How GPFS would behave with that and is there a technical reason for avoiding this
setup?<o:p></o:p></span></p>
<p><span style="font-size:12.0pt;color:black">Another alternative would be independent mount point + symlink, but I really would prefer to avoid symlinks.<o:p></o:p></span></p>
<p><span style="font-size:12.0pt;color:black"><o:p> </o:p></span></p>
<p><span style="font-size:12.0pt;color:black">Thanks a lot,<o:p></o:p></span></p>
