I read some basic information from homepage and Wikipedia.
Looks like 2.0, 2.1, 2.2 versions have been released in last years.
Shouldn't Debian package been updated to 2.x as well?
If staying on 1.8, 1.8.6 and later clients can interoperate 2.x servers.
But Debian package is still at 1.8.5 with some bugs that are fixed in later
versions.
Maybe you should ask wider opinion what to do with Lustre in Debian.
