Hi list,
I tried to understand the output of "CEPH DF" , finally I got it but it's
really confusing in the POOLS section, so I sent out the mail and see if any
good suggestion to make it better.
Here is an example from my cluster
GLOBAL:
SIZE AVAIL RAW USED %%RAW USED
8153G 5962G 2191G 26.88
POOLS:
NAME ID USED %%USED MAX AVAIL SIZE
base_tier 1 960G 11.77 2647G
245793
cache_tier 2 134G 1.65 212G 34526
Currently, the
USED = how many data in particular pool , so my base_tier has 960G
data and cache_tier has 134G data
%%USED = USED /GLOBAL.SIZE, this is really strange, users are likely
to think the %%USED should be USED/ POOL.CAPACITY
%%MAX_AVAIL = how many available space in particular pool ,calculated
by max( osdi.avail / osdi. weight)
OBJECTS = how many objects in the pool
I think it would be better to have
POOLS:
NAME ID SIZE OBJECTS USED
%%USED MAX_AVAIL
base_tier 1 7878G 245793
960G 12.29 2647G
cache_tier 2 346G 34526 134G
38.72 212G
What do you think? Any impact to other tools?
