Hi Sage,
Regarding the replay assert I posted yesterday , it seems it is happening only with Stupid and *not* with bitmap allocator.
Thread 1 "ceph-osd" received signal SIGABRT, Aborted.

Debugging further and printing some extra log , I found this..

/root/ceph-master/src/os/bluestore/StupidAllocator.cc: 306: FAILED assert(rm.empty())
So, for inode 0 it is not entering in the following loop from where rm is freed.
for (unsigned i = 0; i < free.size() && !rm.empty(); ++i) {
So, it seems free.size is 0 at this point , not sure why though ?
I have full verbose log , let me know if you need that.
Thanks & Regards
Somnath
