PG的全称为Placement Group(放置组),放置顾名思义放置Object的载体。PG的创建是在创建Pool的时候根据指定的数量进行创建。PG的数量与副本数也有关系,比如是3副本的则会有3个相同的pg存在于3个不同的osd上,以filestore为例pg其实在osd的存在形式就是一个目录。其目录的命名规则为 {pool-id}.{pg-id}_head 和 ...

Autolysis, like PG turnover, can release PG breakdown products from bacterial cells; however, PG turnover is a controlled process in normal PG synthesis of live cells (10, 12, 13), whereas autolysis results in cell death. Fratricidal PG lysis of noncompetent pneumococcal cells is pronounced in biofilms, which were studied and are discussed below.
