Subject: CEPH_FEATURE_OSD_CACHEPOOL always required when osd cache pool exist ?
Date: Tue, 21 Jan 2014 09:28:00 +0100 [thread overview]
Message-ID: <52DE2F90.9030201@ksperis.com> (raw)
Hi all,
About 0.75, when I created cache pool, kernel client like rbd or cephfs
make error "feature set mismatch". (Even if the device is not on the
cached pool)
$ rbd map rbd/myrbd => OK
$ ceph osd pool create otherpool1 100 100
$ ceph osd pool create otherpool2 100 100
$ ceph osd tier add otherpool1 otherpool2
$ ceph osd tier cache-mode otherpool2 writeback
$ rbd map rbd/myrbd
kern log >> libceph: mon2 10.2.0.90:6789 feature set mismatch, my
4a042a42 < server's 84a042a42, missing 800000000
Does the commit
https://github.com/ceph/ceph/commit/431a13eb370310a383abceeb509fe204a519e087
fix this ?
Regards,
Laurent Barbe
