Re: [CentOS] Auto-updates -- Bad Idea?
If you don't want your system to break unexpectedly, do not enable automatic updates; especially if you are running any packages with non-standard configurations. In some cases, with bare packages and stock configurations, automatic updates may prove to be a viable and SEMI-safe solution. But, if you wish to maintain the integrity of a production system, I would suggest that you do not use them.

I see some posts on the web encouraging the use of yum-cron, but I'd like to know what people feel about the use of automatic updates. That is, for a server (non-desktop) system, automatic updates could break things or have other unforeseen consequences, and that could happen at the worst of times, since the process runs regularly. On the other hand, for small businesses without highly trained sysadmins or ones with enough time to baby their servers, missing critical updates to, say openssl or some other mission-critical package could spell disaster.

Try to strace heartbeat process and check errno from shmget() and

Re: [CentOS] heartbeat package in extras trouble with 5.4
Ok, so for some reason, I had shmax set to 64GB. Prior to 5.4, I'm
guessing that i386 just ignored this absurd value, but now, it forces
the value to be 0:
r...@fc-fmcln02:/var/log$ ipcs -l
-- Shared Memory Limits
max number of segments = 4096
max seg size (kbytes) = 0
max total shared memory (kbytes) = 0
min seg size (bytes) = 1
I set kernal.shnmax back to it's default value and this seemed to fix
the heartbeat issues with allocating shared memory segments.

It looks like it's trying to find an existing shared memory segment?
From sysctl.conf:
# Controls the maximum size of a message, in bytes
kernel.msgmnb = 65536
# Controls the default maxmimum size of a mesage queue
kernel.msgmax = 65536
# Controls the maximum shared segment size, in bytes
kernel.shmmax = 68719476736
# Controls the maximum number of shared memory segments, in pages
kernel.shmall = 4294967296
$ ipcs

This seems to be the issue. Any other ideas?
Try to strace heartbeat process and check errno from shmget() and
compare it against shmget(2) `ERRORS' section. Maybe you need to set
some sysctls.

[CentOS] heartbeat package in extras trouble with 5.4
I just recently upgraded a box from i386 5.3 - 5.4. The box has heartbeat packages installed from extras: heartbeat-pils-2.1.3-3.el5.centos heartbeat-stonith-2.1.3-3.el5.centos heartbeat-devel-2.1.3-3.el5.centos heartbeat-2.1.3-3.el5.centos The heartbeat daemon no longer starts.. the init script reports a success, as well as the logs: May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: Enabling logging daemon May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: logfile and debug file are those specified in logd config file (default /etc/logd.cf) May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: Version 2 support: false May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: WARN: logd is enabled but logfile/debugfile is still configured in ha.cf May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: ** May 4 22:33:10 fc-fmcln02 heartbeat: [9344]: info: Configuration validated. Starting heartbeat 2.1.3 May 4 22:33:10 fc-fmcln02 heartbeat: [9345]: info: heartbeat: version 2.1.3 May 4 22:33:11 fc-fmcln02 heartbeat: [9345]: info: Heartbeat generation: 1208455492 However, the daemons never actually start. When I run the daemon interactively without the init script, the following error appears: heartbeat[8818]: 2010/05/04_22:23:37 ERROR: Cannot shmget for process status: Invalid argument This may suggest that some libs on the system may have been upgraded and heartbeat is trying to use the old ones? Does anyone have any suggestions on how to get heartbeat working again? Thanks, Josh ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
