    Description

      The "lctl get_param seq.ctl-*.fldb" file stops printing lines after about 4KB is printed (OST0051 if there are two MDTs).  This appears to be a problem in the debugfs/seq_file handling in the kernel module, since lctl gets a short read on its 64KB buffer and retries the read again before stopping. 

      it may be that this is using seq_file instead of debugfs and is limited to 4KB of output?
