Hi,
I have a problem fully utilizing some disks with cephadm service spec. The
host I have has the following disks:
4 SSD 900GB
32 HDD 10TB
I would like to use the SSDs as DB devices and the HDD devices as block. 8
HDDs per SSD and the available size for the DB would be about 111GB
(900GB/8).
The spec I used does not fully utilize the SSDs though. Instead of 1/8th of
the SSD, it uses about 28GB, so 1/32th of the SSD.
The spec I use:
spec:
objectstore: bluestore
filter_logic: AND
data_devices:
rotational: 1
db_devices:
rotational: 0
I saw "limit" in the docs but it sounds like it would limit the amount of
SSDs used for DB devices.
How can I use all of the SSDs‘ capacity?
Best,
Christian
