[Lustre-discuss] Is it safe to run MDS, MGS & OSS on the same machine ?

We're running low on physical machines, and want to deploy MGS, MDS and OSS on the same machine, is it officially supported ?
I know that MGS and MDS can be put on the same machine, but not sure about OSS and MDS.

This will work, but if the node fails then there is no recovery for operations in progress and the clients can get an IO error for operations in progress.

Cheers, Andreas
