Description
Currently, luminous has introduced new purge queue journal whose inode number is 0x500
but cephfs-journal-tool does not support this journal type.
we have encounter a purge queue journal corruption in our cluster, and mds can not consume purge queue journal.
this makes delete operation can not take real effect, and eventually our osd almost reached 100% full.
then i have simply modified the code in cephfs-journal-tool to support purge queue, and it saved us 50% space.
