What command did you use to disable the OST? There is a way to disable the OST on all the clients, but there is also a way to deactivate it on the MDS. The latter method should prevent the MDS from allocating any new files to the OST, but still allow clients to read and delete files on that OST. -- Rick Mohr Senior HPC System Administrator National Institute for Computational Sciences http://www.nics.tennessee.edu _______________________________________________ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
