[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We have resolved a number of issues that v0.61.x Cuttlefish users have 
been hitting and have prepared another point release, v0.61.4. This 
release fixes a rare data corruption during power cycle when using the XFS 
file system, a few monitor sync problems, several issues with ceph-disk 
and ceph-deploy on RHEL/CentOS, and a problem with OSD memory utilization 
during scrub.

Notable changes include:

 * mon: fix daemon exit behavior when error is encountered on startup
 * mon: more robust sync behavior
 * osd: do not use sync_file_range(2), posix_fadvise(...DONTNEED) (can 
   cause data corruption on power loss on XFS)
 * osd: avoid unnecessary log rewrite (improves peering speed)
 * osd: fix scrub efficiency bug (problematic on old clusters)
 * rgw: fix listing objects that start with underscore
 * rgw: fix deep URI resource, CORS bugs
 * librados python binding: fix truncate on 32-bit architectures
 * ceph-disk: fix udev rules
 * rpm: install sysvinit script on package install
 * ceph-disk: fix OSD start on machine reboot on Debian wheezy
 * ceph-disk: activate OSD when journal device appears second
 * ceph-disk: fix various bugs on RHEL/CentOS 6.3
 * ceph-disk: add 'zap' command
 * ceph-disk: add '[un]suppress-activate' command for preparing spare 
   disks
 * upstart: start on runlevel [2345] (instead of after the first network 
   interface starts)
 * ceph-fuse, libcephfs: handle mds session reset during session open
 * ceph-fuse, libcephfs: fix two capability revocation bugs
 * ceph-fuse: fix thread creation on startup
 * all daemons: create /var/run/ceph directory on startup if missing
