similar to: machine responsiveness with centos 5.1

Hi all, I used to use centos 4.5 on an AMD 4800+ with 2GIG ram. Now I use centos 5.1 on AMD 6400+ with 4GIG RAM. The system responsiveness is different between the two. I noticed that centos 5.1 seems to be swapping programs out of memory at times resulting in slowness (perceived by me). I played with swappiness (/proc/sys/vm/) setting to 10, then 1 then 0. Still resulted in the same perceived

Dear list, I thought I'd just share my experiences with this 3Ware card, and see if anyone might have any suggestions. System: Supermicro H8DA8 with 2 x Opteron 250 2.4GHz and 4GB RAM installed. 9550SX-8LP hosting 4x Seagate ST3250820SV 250GB in a RAID 1 plus 2 hot spare config. The array is properly initialized, write cache is on, as is queueing (and supported by the drives). StoreSave

Hi, after one month with gmirror and gjournal running on a 7.0-RELEASE #p2 amd64 (built from latest CVS source), the box hung a couple of times when on high disk load. Finally, while building some port it won't boot for no reason obvious to me. This is what I get with kernel.geom.mirror.debug=2: ata2-master: pio=PIO4 wdma=WDMA2 udma=UDMA133 cable=40 wire ad4: 476940MB <SAMSUNG HD501LJ

Hi, what would be a good value for /proc/sys/vm/min_free_kbytes on a Dual-CPU EM64T System with 8 GB of memory. Kernel is 2.6.9-42.0.3.ELsmp. I know that the default might be a bit low. Unfortunatelly the documentation is a bit weak in this area. We are experiencing responsiveness problems (and higher than expected load) when the system is under combined memory+network+disk-IO stress.

Hi folks. I'm posting this to both the Fedora as well as the CentOS lists in hopes that somewhere, someone can help me figure out what's going on. I have a dual Xeon 3GHz server that's performing rather slow when it comes to disk activities. The machine is configured with a single 160 GiB OS drive (with CentOS 5.0) and 4x500 GiB drives setup in a RAID-5 configuration.

Hello, while reading/writing dvd on 6-STABLE (can't remember on 7-STABLE right now), I'm getting the message buffer filled by errors. This is my dvd-rw $ sysctl dev.acd.0.%desc dev.acd.0.%desc: PIONEER DVD-RW DVR-109/1.58 attached to $ sysctl dev.atapci.1.%desc dev.atapci.1.%desc: VIA 8237A UDMA133 controller And the followings are some examples of the error:

I have 2 gluster servers in replicated mode on EC2 with ~4G RAM CPU and RAM look fine but over time the system becomes sluggish, particularly networking. I notice when sshing into the machine takes ages and running remote commands with capistrano takes longer and longer. Any kernel settings people typically use?

Hello, I'm building a new system for a friend and I bought a Pioneer DVD-120s drive for him because it was a newer version of the drive I use (DVD-116) and my friend uses (DVD-106s) with FreeBSD. The problem is that FreeBSD cannot probe the drive for some reason. I've tried twiddling the ATAPI_DMA bit, rescanned the drive, and toyed with the cable, but nothing seems to work. The

i cannot read or write any disk inserted in my acd0 <PIONEER DVD-RW DVR-111D/1.29> when this device in udma mode. kernel endlessly repeat that acd0: setting up DMA failed and I can access my data on dvd or cd only if I set atacontrol mode acd0 pio4 Does anybody have such a problem too? is there any ways to bring this device into udma mode again? dmesg: ... atapci1: <ATI IXP600

I'd like to know what the cause of a particular DB server's slowdown might be. We've ruled out IOPs for the disks (~ 20%) and raw CPU load (top shows perhaps 1/2 of cores busy, but the system slows to a crawl. We're suspecting that we're simply running out of memory bandwidth but have no way to confirm this suspicion. Is there a way to test for this? Think: iostat but for

A couple years ago, we moved to Oracle RAC on Linux using ocfs that is SAN attached to an EMC CLARiiON. At the time, there was a reason that we did NOT use EMC's Powerpath (I just can't recall what that reason was). What I'd like to know is if there are any issues with introducing Powerpath now. * RHEL 2.1 AS * 2.4.9-e.38enterprise * ocfs-2.4.9-e-enterprise-1.0.13-1 * EMC

I''m not a windows person, so I am hoping someone can help me with this... I''ve just installed a Windows 2003 Server VM and I would like to make sure that the average disk IO wait is acceptable. In Linux and other *nixes I would normally use sar or iostat for this. I have found perfmon in windows. Will this give me the numbers I need? Thanks, Matt.

Hi, I've been using Conky for some time, a nifty utility to monitor just about anything on the PC. Vital things like CPU, RAM, swap, disks, current song playing in MPD :o) Here's what it looks like : http://www.microlinux.fr/images/bureau_conky.png And with more detail : http://www.microlinux.fr/images/conky_zoom.png Now I wonder... I'd really like to use that to monitor my

Folks I use "yum list installed" to determine if a package has been installed. In particular, I was interested in the "man" program, installed with the command "yum install man". In Centos6, if I look at the results, I see that "man" was installed. This is good. In Centos7, if I look at the results, I see that "man-db" was installed. This

We have 1 system ruining Centos7 that is the NFS server. There are 50 external machines that FTP files to this server fairly continuously. We have another system running Centos6 that mounts the partition the files are FTP-ed to using NFS. There is a python script running on the NFS client machine that is reading these files and moving them to a new dir on the same file system (a mv not a cp).

Hello, I've got a (P)ATA disk in a special frame. The disk itself supports UDMA-100 (and has an 80-ribbon cable), but the frame isn't compatible with that. By default, FreeBSD negotiates UDMA-100, and the console starts to fill with ICRC errors. In the past, I used a patch to ata-all.c that enabled the following entry in loader.conf to force the disk to UDMA-33, so it worked fine:

Hi Matt- Thank you for this very detailed and thoughtful reply.

Hi All, What is the best way to remotely monitor/administer a group of xen domUs across a network? We''re planning to deploy a few H/W servers with paravirtualized domUs. What are the best alternatives? What works and What doesn''t? Share your experiences. Cheers Rajan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com
