ceph pool compression lz4

[godfather007]

Hi,

to save some space on our ssd-pool i've enabled compression on the pool:

ceph osd pool set VMS compression_algorithm lz4
ceph osd pool set VMS compression_mode aggressive

with:

ceph df detail, i can get some details but cannot verify if it works.

Any hints? Is "ratio" needed as well?


Thanks in advance,

Martijn

changed aggressive to force which leads to some changes

deduplication would be nice :-D
