Hi Experts I'm trying to determine whether SQLite will properely work on Lustre. From a quick search it seems that some people use it successfully using flock/localflock mount option. But I have doubts. I'm interested in 2 scenarios: - SQLite works properely for single Lustre node. - SQLite files are accessed simultanously by processes on more than one node.
In SQLite documentation (http://www.sqlite.org/lockingv3.html) there is statement that this db engine uses advisory locks to protect shared date. I know Lustre doesn't implement this yet. So my questions are: - Am I right suspecting that for current Lustre version (1.6.6) there is real risk of SQLite files corruption (in a sense of their integrity - not from fs point of view) even if using flock option? - Are advisory locks still planned to come with 1.8 version (as it is indicated in current Lustre Operation Manual, but there is no such feature in November Roadmap slide on wiki.lustre.org site)? Thanks in advance.
