You can check linux source code to see the feature supported by kernel client.
e.g. linux 4.13-rc5 (https://github.com/torvalds/linux/blob/v4.13-rc5/drivers/block/rbd.c) in drivers/block/rbd.c: /* Feature bits */ #define RBD_FEATURE_LAYERING (1ULL<<0) #define RBD_FEATURE_STRIPINGV2 (1ULL<<1) #define RBD_FEATURE_EXCLUSIVE_LOCK (1ULL<<2) #define RBD_FEATURE_DATA_POOL (1ULL<<7) #define RBD_FEATURES_ALL (RBD_FEATURE_LAYERING | \ RBD_FEATURE_STRIPINGV2 | \ RBD_FEATURE_EXCLUSIVE_LOCK | \ RBD_FEATURE_DATA_POOL) So far only supports layering, striping, exclusive lock, data pool. > On Aug 15, 2017, at 9:34 PM, moftah moftah <moft...@gmail.com> wrote: > > I dont think so , > I tested with with kernel-4.10.17-1-pve which is proxmox5 kernel and that one > didnt have object-map support > > had to disable the feature from the rbd image in order for the krbd rbd > module to deal with it and not complain about features > > > Thanks > > > > On Tue, Aug 15, 2017 at 9:25 AM, David Turner <drakonst...@gmail.com > <mailto:drakonst...@gmail.com>> wrote: > I thought that object-map, introduced with Jewel, was included with the 4.9 > kernel and every kernel since then. > > > On Tue, Aug 15, 2017, 7:26 AM Shinobu Kinjo <ski...@redhat.com > <mailto:ski...@redhat.com>> wrote: > It would be much better to explain why as of today, object-map feature > is not supported by the kernel client, or document it. > > On Tue, Aug 15, 2017 at 8:08 PM, Ilya Dryomov <idryo...@gmail.com > <mailto:idryo...@gmail.com>> wrote: > > On Tue, Aug 15, 2017 at 11:34 AM, moftah moftah <moft...@gmail.com > > <mailto:moft...@gmail.com>> wrote: > >> Hi All, > >> > >> I have search everywhere for some sort of table that show kernel version to > >> what rbd image features supported and didnt find any. > >> > >> basically I am looking at latest kernels from kernel.org > >> <http://kernel.org/> , and i am thinking > >> of upgrading to 4.12 since it is stable but i want to make sure i can get > >> rbd images with object-map features working with rbd.ko > >> > >> if anyone know please let me know what kernel version i have to upgrade to > >> to get that feature supported by kernel client > > > > As of today, object-map feature is not supported by the kernel client. > > > > Thanks, > > > > Ilya > > _______________________________________________ > > ceph-users mailing list > > ceph-users@lists.ceph.com <mailto:ceph-users@lists.ceph.com> > > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > > <http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com> > _______________________________________________ > ceph-users mailing list > ceph-users@lists.ceph.com <mailto:ceph-users@lists.ceph.com> > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > <http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com> > > _______________________________________________ > ceph-users mailing list > ceph-users@lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
