Hi,
I am not familiar with Robinhood internals. Is the client or server
side version that matters? I would guess its only the client version
that matters. The lustre client library should be able to abstract
any discrepancies with older versions.
We have two 2.1.0 systems (server side). Clients are at 2.4.
Thanks for your feedback.
I agree, in a perfect world, liblustreapi should abstract changes in
Lustre, but this is not the case... The defined structures change along
Lustre versions, so robinhood has to be able to manage all possible
structures from 1.8 to now
(it used to support 1.4 and 1.6 too, but this must be broken now :))
Also, robinhood receives changelogs in the server-size format, so it
also has to deal with the version of records its receives.
BTW, to read changelogs, it is recommanded to run robinhood on a client
which runs the same version as servers.

Thomas
