Hi,
Could you please be more specific which version you are using that had a problem? The
2.8.5x builds are development builds and shouldn't really be used for anything except
testing. That said, if there is a compatibility problem then this needs to be fixed
before the 2.9.0 release.
There should definitely be compatibility between 2.8.0 and 2.9.0 clients and servers
(excluding new features), so something is definitely wrong.
Cheers, Andreas

Hello everybody,
Recently I noticed that something is changed inside the
lustre-client-master (2.8.xx)
The client is not able to read the data from OSTS.
It is able to mount filesystem and stat files from the server 2.7,
but unable to read any data looks like OSTS did not answer.
If I rollback client to 2.8.0
(
https://build.hpdd.intel.com/job/lustre-b2_8/arch=x86_64,build_type=clien...)
then everything is working as expected.
Are there some compatibility matrix which I missed?
Thanks,
Arman.
