Hey All,
I'm running a test of bluestore in a small VM and seeing 2x overhead
for each object. Here's the output of df detail:
GLOBAL:
SIZE AVAIL RAW USED %RAW USED OBJECTS
20378M 14469M 5909M 29.00 772k
POOLS:
NAME ID CATEGORY QUOTA OBJECTS QUOTA
BYTES USED %USED MAX AVAIL OBJECTS DIRTY
READ WRITE RAW USED
rbd 0 - N/A N/A
0 0 14469M 0 0 0
0 0
cephfs_data 1 - N/A N/A
2446M 14.46 14469M 788850 770k 408
2490k 2446M
cephfs_metadata 2 - N/A N/A
44838k 0.30 14469M 1744 1744 3335
295k 44838k
This is on a VM with all daemons & 20gb disk, all pools are of size 1.
Is this the expected amount of overhead per object? Is there anyway to
tweak bluestore settings?
Thanks,
Pavel
