buffer_anon leak during deep scrub (on otherwise idle osd)
Added by Sage Weil over 6 years ago.
Updated over 6 years ago.
Description
observed gobs of ram (11gb rss) and most of it buffer_anon (~8gb) on a basically idle cluster with replication, ec, and cache tiering. 12.2.0
- Subject changed from buffer_anon leak on mostly-idle osd to buffer_anon leak during deep scrub (on otherwise idle osd)
definitely happens from an ec pool.
- Priority changed from Urgent to Immediate
- Status changed from Need More Info to Fix Under Review
- Backport set to luminous
ok, the problem is that as scrub (or whatever) happens, the bluestore cache is populated, but the attrs weren't in the right mempool, which mean we bloated the overall process footprint.
- Status changed from Fix Under Review to Pending Backport
- Copied to Backport #21650: luminous: buffer_anon leak during deep scrub (on otherwise idle osd) added
- Status changed from Pending Backport to Resolved
