Nothing technically wrong with it, but as was discussed previously, not
much benefit to lustre over other filesystems when using only one OSS/OST.
Any parallelism by lustre by using multiple OSTs in a single box can be
had with other filesystems (such as ZFS). The main beauty of a
distributed filesystem is the parallelism among */multiple destination
servers/*. That's what makes it so scalable.
So, yes, not recommended, but yes can be done. I did it that way just to
learn lustre long ago.

Hello
I know this is not lustre recommended architecture. But the vendor has
proposed us to use single server as mds and oss with one ib card
connecting to storage of 120 tb.
Is it even possible ? The performance will go down but beside
performance doea lustre 2.x support this kind of configuration?
