erasure-code: lrc plugin workload Add a workload that uses the lrc erasure code plugin. Instead of adding it to suites/rados/thrash-erasure-code/workloads, a new suite is created at suites/rados/thrash-erasure-code-big because it needs more OSDs than other erasure code plugins. The alternative would be to increase the number of OSDs for all erasure code plugins, but that would needlessly increase the resources requirements. * cluster/12-osds.yaml creates a 12 OSDs, 3 MONs cluster * thrash-erasure-code-big/thrashers/.yaml are the same as thrash-erasure-code/thrashers/.yaml except they require that at least 8 OSDs are in at all times (instead of 4) because lrc PGs with k=4, m=2, l=3 are undersized if they do not have 8 OSDs. It is possible that crush fails to map 8 OSDs when only 8 OSDs are available, but that must not disturb the workload because min_size is 4. http://tracker.ceph.com/issues/11666 Fixes: #11666 Signed-off-by: Loic Dachary <ldachary@redhat.com> 2015-05-26 08:38:50 +00:00			`roles:`
