Description Ken Dreyer (Red Hat) 2015-08-05 19:31:53 UTC

This bug tracks the fix of bz 1247752 for Ubuntu 12.04 and 14.04 platforms.

Description of problem:

Log::reopen_log_file() does not take a lock, and _flush() might continue writing to m_fd after it has been closed.  This could result in lost log entries, or it could result in the log being written to an fd which has been opened by the filestore.  That latter case could cause data corruption.

Comment 1 Ken Dreyer (Red Hat) 2015-08-05 20:45:55 UTC

For non-RHEL, the fix will be in the Ceph v0.80.8.4 packages.
