Re: [Linux-cluster] FAQ: mounting another gfs fileystem under gfs



Thanks Robert,
i will go for it with RHEL 4 update 4.
It's a 2 node cluster, and my idea was that the risk is in situation when for some reason
the /gfs gets locked .. nested could get unaccessible as well.

Hi Jan,

AFAIK, what you've described is supposed to work just fine.
However, this and similar scenarios don't get a lot of testing.
A few weeks back, I uncovered some bugs in a beta version of RHEL5
doing just that, which we consequently fixed.  So I'd say:  Go ahead
and do it, and if you run into problems, open up a bugzilla.
