RHBA-2013:0337 - Bug Fix Advisory

Topic

Updated ctdb packages that fix various bugs and are now available for Red Hat
Enterprise Linux 6.

Description

The ctdb packages provide a clustered database based on Samba's Trivial Database
(TDB) used to store temporary data.

The ctbd packages have been upgraded to upstream version 1.0.114.5, which
provides a number of bug fixes over the previous version. (BZ#838885)

This update also fixes the following bugs:

• While running ctdb on the GFS2 file system, ctdb could ban a stable node when

another node was started or stopped. This bug has been fixed by the rebase and
stable nodes get no longer banned in the described scenario. (BZ#758367)

• Previously, on the Glusterfs file system, the ctdb lock file and configuration

files were shared. Consequently, the ctdbd daemon running on a node terminated
unexpectedly when another node in the cluster was brought down. This bug has
been fixed by the rebase and ctdbd no longer crashes in the described scenario.
(BZ#821715)

• After removing a ctdb node, the "ctdb status" command reported the same number

of nodes as before the node was removed. A patch has been provided to address
this issue and "ctdb status" now returns an accurate number of nodes after a
remove operation. (BZ#866670)

Users of ctdb are advised to upgrade to these updated packages, which fix these
bugs.
