Hi,
I'm seeing this crash on multiple OSDs while upgrading to Jewel:
0> 2016-08-10 19:41:40.686944 7f20d37f1700 -1 common/buffer.cc: In function 'void ceph::buffer::ptr::copy_in(unsigned int, unsigned int, const char*, bool)' thread 7f20d37f1700 time 2016-08-10 19:41:40.682052
common/buffer.cc: 977: FAILED assert(o+l <= _len)
It started to happen when the OSDs came under load due to a node failing (hardware) which brought a lot of PGs in a unclean state.
I already filed a tracker issue for it: http://tracker.ceph.com/issues/16982
All machines are running Ubuntu 14.04 with the 4.4 kernel.
Wondering if somebody has seen this before. This cluster is very down at the moment..
Wido
