    Description

      In attempt to create a large stripe system with lvm I ran into a issue that prevented the MGT from mounting. The system has 4 OSS with 28 real disk but I used lvm to create 56 OST per OSS thus slicing the disk into 8 partitions to use. When I went to mount the file system the MGT refused to mount and gave the following error.

      LustreError: 19657:0:(mgs_llog.c:1540:add_param()) params are too long:

                LU-3004 mgs: don't add duplicated param
    
    mgs target info param does not need contain duplicated key val pair.
    It is the same case for lustre disk data params member.
