[pve-devel] [PATCH ceph 0/2] Build rocksdb in non-debug mode

[Alexandre Derumier]

They are a bug in current debian packaging,
where rocksdb is build in debug mode (not inheriting from cmake flags)

patch 1 already exist in ubuntu
patch 2 is a newer patch commited in ceph recently

(patch 2 should be enough, but I'm keeping patch1 by security).


I have tested it, 4k randwrite iops x2, 

fio: 4k randwrite:queue depth=64:sync write:  cache=none:
before:  16000 iops
