Re: [Lustre-discuss] Lustre-discuss Digest, Vol 74, Issue 4

FYI.
I used to put everything (MGS/MDS/OSS/client) on one node for test
purpose. It worked fine and ran for many days without any issue. But you
might watch over when the load on the node goes high. And again, that
was a test system, not used for production.
Also, you may consider to use vm for separating at least MGS/MDS.

Yujun

If for some reasons you have to reboot, let's say a client where the MGS is, you may get into all sort of problems. Again, this is very odd and won't buy you anything.
