Hmmm unfortunately it looks like the public functions got changed and so there isn't the standard ceph_stat any more. Fixing the wiring wouldn't be that complicated if you can hack on the code at all, but there are some other issues with the Samba VFS implementation that have prevented anyone from prioritizing it so far. (Namely, smb forks for every incoming client connection, which means every smb client gets a completely independent cephfs client, which is very inefficient.) -Greg > > thanks for your help, > Ansgar > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
