Creo un client per ogni "top level directory" per questo filesystem:
| Code Block |
|---|
[root@c-mon-1 almalinux]# ceph fs authorize cephfs client.allfs / |
...
rwp | tee /etc/ceph/ceph.client.allfs.keyring [client.allfs] key = AQCnHolnBCOgNBAA9Vn36INaHCF5u599JMjtuQ== |
| Code Block |
|---|
[root@c-mon-1 almalinux]# ceph fs authorize cephfs client.terabithome /terabithome rwrwp | tee /etc/ceph/ceph.client.terabithome.keyring [client.terabithome] key = AQA9FIlnaJ5SFBAAdT8gzFgfOp9jq3meON0o+g== [root@c-mon-1 almalinux]# ceph fs authorize cephfs client.slurmctrl /slurmctrl rwrwp | tee /etc/ceph/ceph.client.slurmctrl.keyring [client.slurmctrl] key = AQB4FIlng39/JhAAloEnVIZDpfMz/Zijwjou5Q== |
Il 'p' serve per poter settare le quote
A questo punto devo creare le top level directory. Configuro una macchina di servizio come client (vedi How to mount a ceph file system) e li' monto l'intero filesystem usando il client allfs. Quindi il comando di mount sara' qualcosa tipo:
| Code Block |
|---|
mkdir /cephfs |
...
mount -t ceph allfs@.cephfs=/ /cephfs -o mon_addr=10.70.42.10:6789/10.70.42.9:6789/10.70.42.8:6789,secretfile=/etc/ceph/cephfs.allfs.secret |
A questi punto creo le top level directory e poi posso fare l'umount:
...
| Code Block |
|---|
mkdir /cephfs/terabithome mkdir /cephfs/slurmctrlslurmct umount /cephfs |
Il file /etc/ceph/ceph.client.xyz.keyring serviranno poi nei nodi dove si monta la top level directory xyz
