On Hi Cephers,
I'm building a new Squid cluster with cephadm on Ubuntu 24.04.
After expanding my cluster in the Dashboard (adding my 7 hosts),
I choose throughput_optimized proflie wich create a generic spec for
hybrid HDD/SSD :
service_type: osd
service_id: throughput_optimized
service_name: osd.throughput_optimized
placement:
host_pattern: '*'
spec:
data_devices:
rotational: 1
db_devices:
rotational: 0
encrypted: true
filter_logic: AND
objectstore: bluestore
The cluster is for a LAB environment, on each of the 7 nodes, I have 17
HDD SAS 1.2TB drives and 1 SSD SAS Enterprise 400GB drive.
On my first try, only 28 OSD where created (out of the 119), the others
appeared as down, but they won't start, I didn't find systemd units
created on the hosts.
But, the VGs and LVs where created, there are 17 LVs on the SSD for
WAL/DB of the 17 HDD (yes, small : 29GB).
On my second try, it creates 72 OSDs, still it stops, and never tries to
continue, or re-create the down OSDs.
I didn't manage to find them, but it seems I saw some OSD creation
timeout in the logs...
What can I do to have my missing OSD created ?
I tried restarting, redeploying the orch OSD service, but it only
restart/redeploy le OSDs it has already created...
