Description
In BlueFS::_estimate_log_size_N, the total size of the dir was calculated incorrectly.
It should be the number of dirs multiplied by (avg_size+1).
- Status changed from New to In Progress
- Backport set to squid, reef, quincy
Does avg_dir_size or avg_file_size represent the meaning of the bytes occupied by the name? Or does it have other meanings? @ Igor Fedotov

Yeah, looks like they represent bytes occupied for names. Not sure I understand why we sum avg_dir_size and avg_file_size for the following line though:
size += nodes.file_map.size() * (1 + avg_dir_size + avg_file_size);
What is calculated here should be the total bytes occupied by the names of all files.@ Igor Fedotov
