yum install -y python3 podman chrony lvm2 wget wget -O /root/cephadm https://github.com/ceph/ceph/raw/octopus/src/cephadm/cephadm chmod +x /root/cephadm
./cephadm add-repo --release octopus ./cephadm install
mkdir -p /etc/ceph
Bootstrap monitor med egen IP
cephadm bootstrap --mon-ip 192.168.2.206
Installer basic ceph tools
cephadm add-repo --release octopus cephadm install ceph-common cephadm install ceph
Opret OSD'er med alle diske (få lige specifik kommando fra Hoerup)
ceph orch apply osd --all-available-devices ceph status
Lav ny regel der bruger failure domain på OSD (istedet for 3 hosts)
ceph osd crush rule create-replicated repl1 default osd ceph osd pool ls ceph osd pool set device_health_metrics crush_rule repl1
EC stuff, her med 4+1
ceph osd pool create rbdmeta replicated repl1 ceph osd erasure-code-profile get default ceph osd erasure-code-profile set ec41 k=4 m=1 crush-failure-domain=osd ceph osd pool create rbddata erasure ec41
Hint at denne pool skal bruges til block storage
ceph osd pool application enable rbddata rbd ceph osd pool application enable rbdmeta rbd
Tillad EC blok overwrites
ceph osd pool set rbddata allow_ec_overwrites true
rbd create --size 40G --data-pool rbddata rbdmeta/ectestimage1 rbd ls rbdmeta
Mapper et rbd image ind som blockdevice
rbd map rbdmeta/ectestimage1
Husk at rette /etc/ceph/rbdmap f.eks.
rbdmeta/ectestimage1 id=admin,keyring=/etc/ceph/ceph.client.admin.keyring
systemctl enable rbdmap.service
Mount and shit
