Hello, I'm testing the 0.72 release and thought to give a spin to the zfs support. While I managed to setup a cluster on top of a number of zfs datasets, the ceph-osd logs show it's using the "genericfilestorebackend": 2013-11-06 09:27:59.386392 7fdfee0ab7c0 0 genericfilestorebackend(/var/lib/ceph/osd/ceph-0) detect_features: FIEMAP ioctl is NOT supported 2013-11-06 09:27:59.386409 7fdfee0ab7c0 0 genericfilestorebackend(/var/lib/ceph/osd/ceph-0) detect_features: FIEMAP ioctl is disabled via 'filestore fiemap' config option 2013-11-06 09:27:59.391026 7fdfee0ab7c0 0 genericfilestorebackend(/var/lib/ceph/osd/ceph-0) detect_features: syncfs(2) syscall fully supported (by glibc and kernel) I noticed however that the ceph sources include some files related to zfs: # find . | grep -i zfs ./src/os/ZFS.cc ./src/os/ZFS.h ./src/os/ZFSFileStoreBackend.cc ./src/os/ZFSFileStoreBackend.h A coupel of questions: - is 0.72-rc1 package currently in the raring repository compiled with zfs support ? - if yes - how can I "inform" ceph-osd to use the ZFSFileStoreBackend ?
