Thank you for the info.

I have an other question.

How can I disable az OSS from the cluster, so clisnt nodes do not want 
to make an access to it?

I mean the following:

The node get down, for example HW failure, its raid array has lost. I 
don't care, I just want to disable or remove it from the cluster, and 
the restore the missing (0 sized) files. The following day I repair the 
node, so I want to make it available again.

I know, there is lctl deactivate, but it is only for writing, I need a 
global set.

Thank you,
