Hi all, Today I'm testing CephFS with client-side kernel drivers. My installation is composed of 2 nodes, each one with a monitor and an OSD. One of them is also MDS. root@test2:~# ceph -s cluster 42081905-1a6b-4b9e-8984-145afe0f22f6 health HEALTH_OK monmap e2: 2 mons at {0=192.168.0.202:6789/0,1=192.168.0.200:6789/0}, election epoch 18, quorum 0,1 0,1 mdsmap e15: 1/1/1 up {0=0=up:active} osdmap e82: 2 osds: 2 up, 2 in pgmap v4405: 384 pgs, 5 pools, 16677 MB data, 4328 objects 43473 MB used, 2542 GB / 2584 GB avail 384 active+clean I added data pool to MDS : ceph mds add_data_pool 4 Then I created keyring for my client : ceph --id admin
--keyring /etc/ceph/ceph.client.admin.keyring auth get-or-create
client.test mds 'allow' osd 'allow * pool=CephFS' mon 'allow *'
>
/etc/ceph/ceph.client.test.keyring And I mount FS with : mount -o name=test,secret=AQC9YhBT8CE9GhAAdgDiVLGIIgEleen4vkOp5w==,noatime -t ceph 192.168.0.200,192.168.0.202:/ /mnt/ceph Mount is OK. I can write files to it. I can see files on every clients mounted. BUT... Where are stored my files ? My pool stays at 0 disk usage on rados df Disk usage of OSDs never grows... What did I miss ? When client A writes a file, I got "Operation not permitted" when client B reads the file, even if I "sync" FS. That sounds very strange to me, I think I missed something but I don't know what. Of course, no error in logs. |
