Dear all,
I am building a small Lustre installation (3 storage nodes, 20
clients). I have been wondering whether it is safe to have MDS and OSS
on the same node? I am mostly concerned about data integrity /
deadlocks during a normal Lustre operation.
Regards,
Sebastian

The deadlock issues are between server and client, so co-locating the OSS
and MDS should not result in a deadlock, or data integrity issues.
There might be a performance impact, you should look at memory consumption
as well.
