Hm at the moment not, we have urgent jobs running all arround the day.
All heavy writing tasks we have done to local disks now, none of the error 
messages occoured since.

But its worth to think about that. Updating the clients alone should be 
possible much earlier than updating all machines, and of course can be done 
machine by machine.

But I would assume, that to be sure that no serious file system corruption 
will happen, I should also make a file system check on all the ost and maybe 
also mdt?

But you are right, because 1.6.0.1 servers with 1.6.1 clients is a supported 
configuration right? And therefore updating the clients asap would be a good 
idea!
Any objections about that?
