One of our systems run Apache 2.0.52 (httpd-2.0.52-12.2.ent.centos4 rpm). The kernel we're running is 2.6.9-11.ELsmp. After a few weeks of uptime, Apache refuses to start with the following error in error.log: [crit] (28)No space left on device: mod_jk: could not create jk_log_lock With Apache not running, there're a lot of semaphores left behind by Apache, e.g.: ------ Semaphore

Hey All, I’m attempting to gather stats on usage of the “metal”, by which I mean the physical host’s hardware. I would like to know the CPU, IO, and network stats for the hardware. Normally I would get these from /proc/stat, /proc/diskstat, and ifconfig respectively. However, because of the segregation of VMs and Dom0’s special relationship as a paravirtualized I don’t know if I can trust this

In CentOS 4.1/2, what package contains this library: libstdc++-libc6.2-2.so.3? I installed a couple of the compat- packages, but this library is still missing.

Hello, I noticed that the CPU% reported by xentop appears to be too high. With dom0 idle xentop is reporting between 14-17% CPU utilization while at the same time top in dom0 is reporting 1-4% CPU utilization. I see that the TODO for xentop includes a task to make CPU% more accurate but looking at the code for xentop and libxenstat I''m not sure how to go about this. Assuming the CPU

I read that XFS has problems with 4K Stack size for Linux on 32-bit systems. How did we address this in the centosplus kernel? Since what release of CentOS was this problem resolved? Is there a quick way to know what size the Linux stack is configured to be in a system's that's running?

I tried netperf / netserver with Dom0 / DomU, but I could''nt get a correct NW traffic with xentop. Is there anybody could help me? At Host1''s Dom0, run netperf -H VMIP At Host2''s DomU (with VMIP named TTVM), run netserver At Host1, run xentop this way ->"xentop -n -b -d 1" At Host2, run xentop this way->"xentop -n -b -d 1" In Host2''s

Is there a way to determine what package changed from CentOS 4.1 to 4.2 (or between any two versions)? I need to create a yum repository to upgrade some machines that cannot talk to the Internet. Thanks for any help. ID:FONGVANG

I'm getting a couple of systems that are arriving with the new 3ware 9550sx controller. Does anyone know when this will be natively supported by CentOS? Has anyone built an RPM of the driver/module for this new controller?

I have a total of 20 CentOS 4.1 systems running on fairly new hardware. About 6 of them are experiencing strange hangs without any indication -- nothing in /var/log/messages nor on the console -- sometime within 10-30 minutes after a reboot. The systems still responds to ping but you can't ssh to it. At the console, you could type "root" at the user prompt but it hangs immediately

What's the easiest way to disable a kernel module during kickstart? Is there a syslinux command that could be passed in to prevent a module from loading? TIA!

In our environment, we have a mixture of 32 and 64 bit systems. Would the 64-bit CentOS flavor work 32 bit systems? What kind of impact would this have on performance if the 64-bit OS on 32-bit hardware?

Hi guys, First of all, sorry to send this one here on the centos ml. I know it's kind of off-topic, but the xen-users list seems a dead end, I was hoping some of you guys are experienced in this. I have a problem with a xen 3.4.2 on Centos 5 x86_64 installation, I need to see the total/used/available memory of dom0 when using xentop, however in batch mode it doesn't seem to work. If I use

Hi Asterisk Users, We've been experiencing some tough time regarding a new Asterisk installation connected to the PSTN via an ISDN PRI with a Digium TE121 with the optional VPMADT032 echo cancellation module. For now, I'll focus on something very specific which is summarized on this email's subject. However, here are some general facts for the context: - System pbxfri went

I've read in many places that file systems on Linux do not suffer the same fragmentation problems of Windows systems. No one has provided a clear explanation as to why fragmentation is not an issue for file systems such as ext2/3, reiserfs, xfs, etc. Just curious.

Hello, I would like to determine overall CPU utilization on a server that''s running xen, and log this information to a file - such as sar can do when run in a non-xen environment. I understand that xenmon shows utilization for each domain, but how can I massage this data to get an overall host server utilization? I''m looking for a single value that describes how much of the host

Hi all, sorry to intrude on xen-devel, but I think I need direction from the expertise here. I''ve admin''d Xen servers of various flavors for a couple years, but never seen this before. After a period ranging from several hours to several days, my primary database and development DomU completely locks up. Net disconnects, but CPU(sec) continues to tick in xentop. No errors, and

Hi, Me and another sysadmin has independently been researching a problem where DomU randomly locks (Can’t reach it via xl console, no ping / SSH connection, shown as stuck in running-state in xentop) on two of our separate machines (installed completely independently): Dom0: Debian 7.0 with Xen version: 4.1.4 and xen-utils 4.1.4-3+deb7u1 Debian 7.1 with Xen version: 4.1 DomU: 7.0 7.1(.3)

Hi all, Wondering if anyone knows of any tools I can run on my Dom0 to log various stats (like CPU usage, memory usage, etc) for each guest domain for analysis over a period of time? I can see that xentop displays that information anyway but would be nice to be able to present that information on a web based interface for day to day administration. Also any tools that send out email
