Hi! Is there a good reason why deleting lots of small files (io500 test md_easy/hard_delete) with the files on OSTs are up to two times faster then when using DoM with the whole file(s) on the MDT?
Using server/client 2.13.0 DoM up to 64k, test files < 4k I can see that the actual data deletion with the data on OST is asynchronous, but I see no reason for it to be almost two times faster. Both MDT's and OSTs are SSDs. The situation is basically the same for a single task and for multiple clients with multiple tasks/client. -- Ake Sandgren, HPC2N, Umea University, S-90187 Umea, Sweden Internet: [email protected] Phone: +46 90 7866134 Fax: +46 90-580 14 Mobile: +46 70 7716134 WWW: http://www.hpc2n.umu.se _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
