Re: [Linux-cluster] Newbie question - why the 16 node limit on Cluster Suite and does this also apply to GFS?


I'm also interested in this (just curious). When not using a quorum disk, but
when using GFS/GFS2, would it be possible to create a cluster with more than
16 nodes with actual releases of the cluster suite, or would the software not
allow it?

Maybe GFS would also refuse to create >16 journals or something?

Redhat it mentions a 16 node limit - I just wondered why this limit
was so low, if it's likely to change anytime soon, and whether this
limit also applies to GFS alone?

Currently, the number is limited by qdiskd, which supports 16 slots, only.

Even though GFS is not limited to 16 nodes, this is what Red Hat currently
