Hello list,
i have a strange issue creating cephfs subvolumegroup with dedicated pools....
We have four fs (volumes); one is "backup" I would like to set up two subvolumegroup "veeampool" and "bareospool" each with dedicated data pools "cephfs.backup.veeam.data" and "cephfs.backup.bareos.data". Both EC42 with overwrites enabled and application cephfs. Pls see below.
isceph@ceph-deploy:~$ sudo ceph fs subvolumegroup create backup veeampool --pool_layout cephfs.backup.veeam.data
...First one is ok.
isceph@ceph-deploy:~$ sudo ceph fs subvolumegroup create backup bareospool --pool_layout cephfs.backup.bareos.data Error EINVAL: Invalid pool layout 'cephfs.backup.bareos.data'. It must be a valid data pool
Did you forget to add the data pool to the volume (file system)? https://docs.ceph.com/docs/master/cephfs/administration/#file-systems See "add_data_pool". -- Patrick Donnelly, Ph.D. He / Him / His Principal Software Engineer Red Hat Sunnyvale, CA GPG: 19F28A586F808C2402351B93C3301A3E258DD79D
