Ok , I think I found out what is happening in my environment. This drive is formatted with 512 logical block size. BitMap allocator is by default is working with 4K block size and the calculation is breaking (?). I have reformatted the device with 4K and it worked fine. I don't think taking this logical block size parameter as user input may not be *wise*. Since OS needs that all devices is advertising the correct logical block size here. /sys/block/sdb/queue/logical_block_size Allocator needs to read the correct size from the above location. Sage/Ramesh ?

Mark/Sage, That problem seems to be gone. BTW, rocksdb folder is not cleaned with 'make clean'. I took latest master and manually clean rocksdb folder as you suggested.. But, now I am hitting the following crash in some of my drives. It seems to be related to block alignment. 0> 2016-06-07 11:50:12.353375 7f5c0fe938c0 -1 os/bluestore/BitmapFreelistManager.cc: In function 'void BitmapFreelistManager::_xor(uint64_t, uint64_t, KeyValueDB::Transaction)' thread 7f5c0fe938c0 time 2016-06-07 11:50:12.349722 os/bluestore/BitmapFreelistManager.cc: 477: FAILED assert((offset & block_mask) == offset) ceph version 10.2.0-2021-g55cb608 (55cb608f63787f7969514ad0d7222da68ab84d88) 1: (ceph::__ceph_assert_fail(char const*, char const*, int, char const*)+0x80) [0x5652219dd0a0] 2: (BitmapFreelistManager::_xor(unsigned long, unsigned long, std::shared_ptr<KeyValueDB::TransactionImpl>)+0x12ed) [0x5652216af96d] 3: (BitmapFreelistManager::create(unsigned long, std::shared_ptr<KeyValueDB::TransactionImpl>)+0x33f) [0x5652216b034f] 4: (BlueStore::_open_fm(bool)+0xcd3) [0x565221596683] 5: (BlueStore::mkfs()+0x8b9) [0x5652215d89b9] 6: (OSD::mkfs(CephContext*, ObjectStore*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, uuid_d, int)+0x117) [0x5652212776c7] 7: (main()+0x1003) [0x565221209533] 8: (__libc_start_main()+0xf0) [0x7f5c0c8f7830] 9: (_start()+0x29) [0x5652212588b9] NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this.

Hi Somnath, Did Sage's suggestion fix it for you? In my tests rocksdb wasn't building properly after an upstream commit to detect when jemalloc isn't present: https://github.com/facebook/rocksdb/commit/0850bc514737a64dc8ca13de8510fcad4756616a I've submitted a fix that is now in master. If you clean the rocksdb folder and try again with current master I believe it should work for you.
