Hobbit server doesn't start on CentOS 5 with hobbit-4.2.0-7.el5.re.i386.rpm installed
by spa＠syntec.co.uk 01 Dec '07

01 Dec '07

I installed an RPM of hobbit-4.2.0 called hobbit-4.2.0-7.el5.re.i386.rpm, which I probably got from here: http://rpm.razorsedge.org/centos-5/RE/repodata/repoview/hobbit-4-4.2.0-7.el5 .re.html It includes the All-in-one patch. So I configured the cfg files and started hobbit, but I get this in hobbitlaunch.log: 2007-11-29 17:33:47 hobbitlaunch starting 2007-11-29 17:33:47 Loading tasklist configuration from /usr/libexec/hobbit/server/etc/hobbitlaunch.cfg 2007-11-29 17:33:47 Loading hostnames 2007-11-29 17:33:47 Loading saved state 2007-11-29 17:33:47 Cannot access checkpoint file /usr/libexec/hobbit/server/tmp/hobbitd.chk for restore 2007-11-29 17:33:47 Setting up network listener on 0.0.0.0:1984 2007-11-29 17:33:47 Setting up signal handlers 2007-11-29 17:33:47 Setting up hobbitd channels 2007-11-29 17:33:47 Could not get shm of size 262144: No space left on device 2007-11-29 17:33:47 Cannot setup status channel 2007-11-29 17:33:47 Task hobbitd terminated, status 1 This is the first time I've started it, so I presume that this is normal: "Cannot access checkpoint file /usr/libexec/hobbit/server/tmp/hobbitd.chk for restore". The problem looks like this: "Could not get shm of size 262144: No space left on device". I see that there are two similar issues listed on http://www.hswn.dk/hobbit/help/known-issues.html that relate to FreeBSD, but none of the sysctl keys listed are in this version of Linux: # cat /proc/version Linux version 2.6.18-8.1.15.el5.centos.plus (mockbuild at builder6.centos.org) (gcc version 4.1.1 20070105 (Red Hat 4.1.1-52)) #1 SMP Thu Oct 25 06:49:40 EDT 2007 Google returns 1 result for "Could not get shm of size" "No space left on device" and that was the Known Issues page I've already checked. Any ideas? Also, I noticed that the hobbitd.pid file did not get deleted when hobbitd terminated. It seems like it should have been. Many thanks, Sebastian

Monitoring HP StorageWorks EVA disk array

I checked Deadcat.net and didn't find anything. Does anyone have a script to monitor a HP StorageWorks EVA disk array with Hobbit? Just checking before I start working on it myself. Thanks. -- Robert Herron robert.herron at gmail.com

security hole? server masquerade
by yf.liang＠yahoo.ca 30 Nov '07

We have 2 servers: 1.2.3.4 servera 4.5.6.8 serverb During DR(discovery test), we changed the local name of serverb to servera, to perform test to see that servera applications have been recovered. So, externally both return pings to their original name. However, when logging into serverb, the uname -a returns servera. The change was done by changing /etc/hosts and uname. 4.5.6.8 serverb servera When the hobbit client is running on serverb, all processes have servera in them. Hobbit server starts to report serverb status as servera !! Doesn't the hobbit server check that the ip of the reporting server (serverb) and reject it, since it does not match the ip address of servera? --------------------------------- Be smarter than spam. See how smart SpamGuard is at giving junk email the boot with the All-new Yahoo! Mail

CPU Utilization, Not Good
by jkwade＠futurefrontiers.com 30 Nov '07

Hi, I've asked this several times, but I really have not received a good answer. Hobbit doesn't really seem to monitor cpu utilization correctly. For example, I can look at the load, login to the box, and then run top. Top shows that cpu utilization is at 100%, 0% idle time. However, the "trends" utilization graph shows 20% cpu utilization. Can someone tell me why? Thanks..James James Wade
