Hey, I recently updated to luminous and started deploying bluestore osd nodes. I normally set osd_max_backfills = 1 and then ramp up as time progresses.
Although with bluestore it seems like I wasn't able to do this on the fly like I used to with XFS. ceph tell osd.* injectargs '--osd-max-backfills 5' osd.34: osd_max_backfills = '5' osd.35: osd_max_backfills = '5' rocksdb_separate_wal_dir = 'false' (not observed, change may require restart) osd.36: osd_max_backfills = '5' osd.37: osd_max_backfills = '5' As I incorporate more bluestore osds not being able to control this is going to drastically affect recovery speed and with the default as 1, on a big rebalance, I would be afraid restarting a bunch of osd. Any advice in how to control this better? Thanks, Scott
