You could set an xattr on the dir of your choice to convert it to a subvolume. eg. # setfattr -n ceph.dir.subvolume -v 1 my/favorite/dir/is/now/a/subvol1 You can also disable the subvolume feature by setting the xattr value to 0 (zero) But there are constraints on a subvolume dir, namely: * you can't move/create one subvolume dir under another * you can't hard-link a file across subvolumes * you can't create snapshots on dirs below the subvolume dir, only at subvolume root * if subvolume xattr is set to 1 on parent dir of subvolume dir, then the parent dir now enforces all constraints On Tue, Jun 7, 2022 at 12:39 PM Stolte, Felix <f.stolte@xxxxxxxxxxxxx> wrote: > Hey guys, > > we are using the ceph filesystem since Luminous and exporting > subdirectories via samba as well as nfs.
