      "message": "libceph: for chooseleaf rules, retry CRUSH map descent from root if leaf is failed\n\nAdd libceph support for a new CRUSH tunable recently added to Ceph servers.\n\nConsider the CRUSH rule\n  step chooseleaf firstn 0 type \u003cnode_type\u003e\n\nThis rule means that \u003cn\u003e replicas will be chosen in a manner such that\neach chosen leaf\u0027s branch will contain a unique instance of \u003cnode_type\u003e.\n\nWhen an object is re-replicated after a leaf failure, if the CRUSH map uses\na chooseleaf rule the remapped replica ends up under the \u003cnode_type\u003e bucket\nthat held the failed leaf.  This causes uneven data distribution across the\nstorage cluster, to the point that when all the leaves but one fail under a\nparticular \u003cnode_type\u003e bucket, that remaining leaf holds all the data from\nits failed peers.\n\nThis behavior also limits the number of peers that can participate in the\nre-replication of the data held by the failed leaf, which increases the\ntime required to re-replicate after a failure.\n\nFor a chooseleaf CRUSH rule, the tree descent has two steps: call them the\ninner and outer descents.\n\nIf the tree descent down to \u003cnode_type\u003e is the outer descent, and the descent\nfrom \u003cnode_type\u003e down to a leaf is the inner descent, the issue is that a\ndown leaf is detected on the inner descent, so only the inner descent is\nretried.\n\nIn order to disperse re-replicated data as widely as possible across a\nstorage cluster after a failure, we want to retry the outer descent. So,\nfix up crush_choose() to allow the inner descent to return immediately on\nchoosing a failed leaf.  Wire this up as a new CRUSH tunable.\n\nNote that after this change, for a chooseleaf rule, if the primary OSD\nin a placement group has failed, choosing a replacement may result in\none of the other OSDs in the PG colliding with the new primary.  This\nrequires that OSD\u0027s data for that PG to need moving as well.  This\nseems unavoidable but should be relatively rare.\n\nThis corresponds to ceph.git commit 88f218181a9e6d2292e2697fc93797d0f6d6e5dc.\n\nSigned-off-by: Jim Schutt \u003cjaschut@sandia.gov\u003e\nReviewed-by: Sage Weil \u003csage@inktank.com\u003e\n"
