RHBA-2010:0596 - Bug Fix Advisory
Synopsis
cman bug-fix update
Type/Severity
Bug Fix Advisory
Topic
Updated cman packages that fix bugs are now available for Red Hat Enterprise
Linux 5.
Description
The Cluster Manager (cman) utility provides user-level services for managing a
Linux cluster.
These updated packages fix the following bugs:
- previously, when the clvmd lockspace got assigned the groupd id ZERO,
dlm_controld rejected it.This caused the groupd to be blocked on systems with
large amounts of scsi devices. With this update, id ZERO is not anymore assigned
to clvmd. clvmd can now join the domain with a valid id and correctly interact
with dlm_controld. (BZ#567317)
- previously, running the get_scsi_devices() subroutine caused the fencing agent
fence_scsi to be blocked. With this update, the open3 calls are replaced by qx
and fence_scsi works now without delays. (BZ#580157)
All cman users are advised to upgrade to these updated packages, which resolve
these issues.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
