Hi @all, I'm using ceph Infernalis (9.2.0) in the client and cluster side. I have a Ubuntu Trusty client where cephfs is mounted via ceph-fuse and I would like to put a sub-directory of cephfs in a specific pool (a ssd pool). In the cluster, I have: ~# ceph auth get client.cephfs exported keyring for client.cephfs [client.cephfs] key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX== caps mds = "allow" caps mon = "allow r" caps osd = "allow class-read object_prefix rbd_children, allow rwx pool=cephfsdata, allow rwx pool=poolssd" ~# ceph fs ls name: cephfs, metadata pool: cephfsmetadata, data pools: [cephfsdata poolssd ] Now, in the Ubuntu Trusty client, I have installed the "attr" package and I try this: ~# mkdir /mnt/cephfs/ssd ~# setfattr -n ceph.dir.layout.pool -v poolssd /mnt/cephfs/ssd/ setfattr: /mnt/cephfs/ssd/: Operation not supported ~# getfattr -n ceph.dir.layout /mnt/cephfs/ /mnt/cephfs/: ceph.dir.layout: Operation not supported Here is my fstab line which mount the cephfs: id=cephfs,keyring=/etc/ceph/ceph.client.cephfs.keyring,client_mountpoint=/data1 /mnt/cephfs fuse.ceph noatime,defaults,_netdev 0 0 Where is my problem? Thanks in advance for your help. ;) -- François Lafont _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
