 Description   

Not all files that are stored in CONFIGS directory should be processed. For example there are ".bak" files which created during change_nids operation and used to store non-modified copy. Currently blacklist is used to process CONFIGS directory (".bak"s are excluded), but using whitelist looks more robust.

Here is example of some MDT CONFIG directory list

# ls /mnt/fs2mdt/CONFIGS/
lustre-client   lustre-MDT0000  lustre-MDT0001  lustre-MDT0002  lustre-MDT0003  lustre-OST0000  lustre-OST0001  lustre-OST0002  lustre-OST0003  mountdata       nodemap         params      

params, node map, mountdata, client, *-MDT, -OST are allowed. What else?

I would say not all *OST* and *MDT* files, only ones that end with *-OSTxxxx and *-MDTxxxx.
