Dear List

In the case where a the MDS and MGS are configured separately, what size
does the MGT have to be?  Reason would suggest it could be quite small, say
32MB.  What would be a sensible minimum? Are there factors which would
indicate a move away from the minimum? For example if it is planned to
configure 2000 lustre filesystems, or the filesystem will consists of 20 000
servers.

In short, are there guidelines for suggesting MGT size?

Regards

Geoff Carrier
