Hi,
I have a filesystem holding many projects (i.e., mounted under
/projects), each project is managed with filesets.
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.
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?
Another alternative would be independent mount point + symlink, but I
really would prefer to avoid symlinks.
This has all the hallmarks of either a Windows admin or a newbie
Linux/Unix admin :-)
Simply put /projects is mounted on top of whatever file system is
providing the root file system in the first place LOL.
Linux/Unix and/or GPFS does not give a monkeys about mounting another
file system *ANYWHERE* in it period because there is no other way of
doing it.
JAB.
