RHBA-2015:1527 - Bug Fix Advisory

Topic

Updated Ceph packages that fix one bug are now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.

Description

Ceph is a massively scalable, open-source, distributed
storage system that runs on commodity hardware and delivers object,
block and file system storage.

This update fixes the following bug in Ceph:

• When reopening log files, Ceph's OSD could end up writing data to the wrong file descriptor. This could result in lost log entries, or it could result in the log being written to a file descriptor which has been opened by the filestore. The latter case could cause data corruption. (rhbz#1246694, rhbz#1247752)
