Let's say that in some previous discussion one of the Sun/CFS people mentioned storing collections of small files into 'ext2' image files on Lustre and then loopback mounting those on clients. While I have mentioned using DB4 or similar indexed databases. > - what would be the main options to tune in order get the best > out of Lustre for small files? [ ... ] That depends a lot on the specific access patterns, and what you mean by "small". I guess, also from reading some previous comments on the topic, that the first thing to consider is appropriate storage backends (e.g. SSD, and Sun/CFS otherwise recommend RAID10) for the MDTs, and maybe even for the OSTs. Lots of small files, lots of IOPs (usually). _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
