This Firefly point release fixes an potential data corruption problem when ceph-osd daemons run on top of XFS and service Firefly librbd clients. A recently added allocation hint that RBD utilizes triggers an XFS bug on some kernels (Linux 3.2, and likely others) that leads to data corruption and deep-scrub errors (and inconsistent PGs). This release avoids the situation by disabling the allocation hint until we can validate which kernels are affected and/or are known to be safe to use the hint on.
We recommend that all v0.80.x Firefly users urgently upgrade, especially if they are using RBD. Notable Changes --------------- * osd: disable XFS extsize hint by default (#8830, Samuel Just) * rgw: fix extra data pool default name (Yehuda Sadeh) For more detailed information, see: http://ceph.com/docs/master/_downloads/v0.80.4.txt Getting Ceph ------------ * Git at git://github.com/ceph/ceph.git * Tarball at http://ceph.com/download/ceph-0.80.4.tar.gz * For packages, see http://ceph.com/docs/master/install/get-packages * For ceph-deploy, see http://ceph.com/docs/master/install/install-ceph-deploy _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
