[gpfsug-discuss] Mounting filesystem on top of an existing filesystem

[Caubet Serrabou Marc (PSI)]

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.


Thanks a lot,

Marc
