[Lustre-discuss] read-only on certain client versions

[John White]

Hello Folks,
	Are there client/server version combinations that would lead to read-only file systems on the client?  We have 2.1.6.0 servers with 1.8.9 clients and it seems every 1.8.9 client just flips mounts to read-only (with no actual message until a write is attempted) yet when the OSSs (at 2.1.6.0) mount, they can write all day long.  

	On write, the 1.8.9 clients log: LustreError: 25284:0:(mdc_locks.c:672:mdc_enqueue()) ldlm_cli_enqueue error: -30 

	Any ideas?
