Hey folks, CentOS / PostgreSQL shop over here. I'm hitting 3 of my favorite lists with this, so here's hoping that the BCC trick is the right way to do it :-) We've just discovered thanks to a new Munin plugin http://blogs.amd.co.at/robe/2008/12/graphing-linux-disk-io-statistics-with-munin.html that our production DB is completely maxing out in I/O for about a 3 hour stretch from

Hey folks, I'm setting up some kickstart files for our standard configs, and need to install munin-node, which of course does not come from you folks, So I set up the Dag Wieers repository but in the repo file I set it to "disabled" so that it will never get used by mistake. Then when adding munin-node I do : yum --enablerepo=dag -y install munin-node But that pulls in a bunch

Hey folks, I've got a RHEL 4.3 system (one of the few I have not yet converted to CentOS) that is running DB2 ... looks like 8.1 Just noticed that committed memory on my Munin graphs has been steadily climbing on a constant curve - yikes! There are 16G of physical ram and the commit is up to 80G now. Fortunately this is evidently not being accessed because I am not doing any swapping.

Hey folks, I posted this as part of another old thread but am starting a new thread for it because I got no response. I've also since found the nfdump mailing list but it seems to be dead. I was not able to find either of these guys in a CentOS repository anywhere, so I'm building them manually. Below was on CentOS 5.2. ---snip--- I'm going to kick this old thread because I'm

Hi, we run an "old" mailserver system which was set up a couple of years ago. The systme dose "everything" what we need(ed). Over the last days I noticed an unnormal increase of the system load up to 10 and lots of users told me that there mailclient connections (sending and receiving) are dropped from time to time. I was planing to exchange the server respectively distribut

Hey folks, We've got some new hardware and are trying to figure out what best to do with it. Either run CentOS right on the bare metal, or virtualize, or several combination options. Mainly looking at : - CentOS on bare metal - CentOS on ESXi 4.0 with local disk - CentOS on ESXi with 1 VM running Openfiler to serve disk to other VMs And want to benchmark these 3 scenarios So far all we

Hi folks, I''m having an issue with rsync between my firewall and an internal box. It seems to be a shorewall issue (or correctly speaking, an issue with my shorewall config) because if I disable shorewall my rsync works fine. And I just can''t find it documented anywhere what I need to do. I have rules like this : root@userver:/etc/shorewall# grep -i Rsync rules

Dear list, as my Xen3 server is finaly becomming ready for production I was wondering if anyone has written a xen usage monitoring/logging tool? Something like xm top, but with continuose logging to a (rr)database. Or a munin plugin? I can''t remember seeing anything simmilar on the list. BTW: where does xm top get the NETTX(k) and NETRX(k) from? For a munin plugin I''d

Hey folks, Is there any way to fake a "yum update" just to get yum to force a download of all the files it needs, without actually installing them. I finally have a RPM cache/proxy working and I just want to populate it. The server I want to actually update cannot be updated until tomorrow but I'd like to do a fake update just to force the RPMs into my cache so they will all be

Hey folks, I created a DomU, installed Linux, and then realized I''d only given it 1 NIC so brought it down to edit the cfg file to give it another NIC. Originally I just had : vif = [''''] And so I guess the defaults worked for the 1 NIC. So I changed it to : vif =

Hey folks, I'm trying to use a 5.3 box to run some JNLP apps, but all I get is a view of XML. I try doing some googling and don't come up with much other than this one thread that says I may need both 32 and 64 bit Java to run JNLP. But it is not clear to me how to do that. thanks, -Alan -- ?Don't eat anything you've ever seen advertised on TV? ? ? ? ?? - Michael Pollan,

Hey folks, I've got a CentOS / RHEL (5.x) environment and am in the process of migrating the 5.3 file server over to an Oracle/Sun 7120 appliance. I want to keep my main 5.3 server as our NIS server but am moving NFS and Samba functions over to the appliance. NFS was a no brainer as one can imagine. Samba seems a bit trickier because of the authentication requirements in the ZFS server.

Hey folks, I have a Sun J4400 SAS1 disk array with 24 x 1T drives in it connected to a Sunfire x2250 running 5.8 ( 64 bit ) I used 'arcconf' to create a big RAID60 out of (see below). But then I mount it and it is way too small This should be about 20TB : [root at solexa1 StorMan]# df -h /dev/sdb1 Filesystem Size Used Avail Use% Mounted on /dev/sdb1 186G 60M

Hey folks, Is there a Linux tool that will monitor a disk and tell me which directories are growing over time? I could cobble something together myself of course, but if there is already a good off-the-shelf solution, why bother? Even if it only checks once per day that would be fine. Graphs would be pretty too :-) cheers, -Alan -- ?Don't eat anything you've ever seen advertised on

Hey folks, I looked at the man page and don't see any way to do this - maybe it is a function of the compression program used I dunno. Is there any way to get gtar to report on the compression it achieved? I can't just check file sizes because I'm writing data to tape. The basic problem is that I know how much data is there to begin with but I don't know how much room it took

Hey folks, I'm at colocaiton in the middle of a big rebuild and it seems I have a faulty CD rom in the server that I need to put Centos on via Kickstart. So I cannot boot the Centos 5.4 net install CD. Is PXE kickstart easy to set up? I have a laptop here with DHCP already going. I google and a bunch of stuff comes up but it does not look simple. I'm just shooting htis out ther eon

Hey folks, I am sure there must be an easy way to do this. I am currently running 5.3 and "yum info db4" tells me that they have version 4.3.29. Is that telling me that this is the version in 5.3? Or that this is the latest version in the 5.x stream? If the former, then how do I find out what release of the db4 software (sleepcat berkeley db) is in 5.7? I don't want to

Hey folks, It looks to me like the httpd on CentOS is stuck at 2.2.2 - what's up with that? Even after a yum upgrade. I need 2.2.10 or greater, and would prefer to get it via yum or at very last an RPM if at all possible. But I cannot even find an RPM out there. For some reason both EPEL and Dag Wieers do not even seem to have an httpd RPM for RHEL5 Any idea where to look? Why are we

Hey guys and gals, Yesterday I had one of my scientists kill one of my servers when his program ran amok and gobbled up all the memory, or forked too many processes, or I'm just not exactly sure what to be honest. Is there something I can run manually in cron to look for rampant programs and kill them? I know that may be hard to discern but I could also include a list if "known
