After several months, we have an important update for the argonaut v0.48.x
series. This release contains a critical fix that can prevent data loss or
corruption in a power loss or kernel panic situation. There are also
several fixes for the OSDs and for the radosgw. We recommend all v0.48.x
users upgrade.
Notes on upgrading:
* If you are using the undocumented ceph-disk-prepare and
ceph-disk-activate tools, they have several new features and some
additional functionality. Please review the changes in behavior
carefully before upgrading.
* The .deb packages now require xfsprogs.
Notable changes since v0.48.2:
* filestore: fix op_seq write order (fixes journal replay after power
loss)
* osd: fix occasional indefinitely hung slow request
* osd: fix encoding for pool_snap_info_t when talking to pre-v0.48
