I need to replace a slow HP MSA20 that's a bottleneck right now (We are an HP shop). HP's only option with 3.5" SATA drives is stuck at SATA I behind a SAS controller. Dell makes an MD1000 that claims SATA II speeds behind a SAS Perc 5/E (Don't know anything about dell). Anyone got any real world info they can share? I need 3.5" SATA II at least 12 drives behind SAS, I am

Hi Group ... havin'' read whatever I could "google" on this topic, I didn`t find any solution: openSuSE 10.2 (out of the box), xenkernel, running on HP Proliant DL360G5 (dual internal networking, plus additional 4-port adapter) gives me eth0 - eth5, but only peth0 - peth3 (as well as vif0 - vif3 and consequentely xenbr0 - xenbr3). I increased the number of loopback-devices

Hi all, I'm running OCFS2 on two system with OpenSUSE 10.2 connected on fibre channel with a shared storage (HP MSA1500 + HP PROLIANT MSA20). The cluster has two node (web-ha1 and web-ha2), sometimes (1 or 2 times on a month) the OCFS2 stop to work on both system. On the first node I'm getting no error in log files and after a forced shoutdown of the first node on the second I can see

Thanks to debugging information from Thomas Mieslinger, I have root-caused the failure of chain.c32 in Syslinux 3.85. I have put out Syslinux 3.86-pre1 and Syslinux 4.00-pre33 which fix the problem. I expect to release a Syslinux 3.86 relatively shortly (ideally in the next two weeks), with bug fixes only. I would like to figure out if there are other bug fixes we can get in in reasonable time,

Hi, folks, Since I've gotten a total of one response in days on the HP forum, maybe the collective mind here has an answer.... As I've mentioned in other posts, we have an HP dl580 g5 that started throwing ECC errors. But wait, it's worse: memory is mirrored.... And the thing is fully populated with 32 DIMMs. I took my best guess, pulled the matching set of DIMMs, and took two

We just installed a new cluster with 6 HP DL380g5, dual single port Qlogic 24xx HBAs connected via two HP 4/16 Storageworks switches to a 3Par S400. We are using the 3Par recommended config for the Qlogic driver and device-mapper-multipath giving us 4 paths to the SAN. We do see some SCSI errors where DM-MP is failing a path after get a 0x2000 error from the SAN controller, but the path gets puts

Hi folks, is it possible to monitor and gather statistics in realtime (CPU, memory, HDD, network, ... - something like dstat) of guest systems with libvirt through console from host system (KVM based)? If yes, do those guests need to be created through libvirt? Thanks for your help and time.

Hi, I am trying to boot a server via PXE with following configured for its PXE. LABEL IMP MENU LABEL IMP LINUX memdisk INITRD linuxIso.iso APPEND iso I haven't been able to get this work, probably only because of network speed. PXE server is on RHEL 5.8 and syslinux 5.x While I was booting the server, I ran dstat on PXE server and saw the outgoing network speed was 400-500Bytes. So looks

I am using Xen 3.1.0 in centos 5.4 I have one VM consuming 100% cpu  and all other VM (linux) become very slow (no ssh and vnc access). I could access host via ssh but not VM. host cpu is about 95% idle using dstat. Pls advise how to avoid this. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I'm trying to do an fsck on an ext3 partition but I'm seeing abysmally slow disk throughput; monitoring with "dstat" (like vmstat) shows ~1200-1500KB/s throughput to the disks. Even with 24hrs of fsck-ing I only get ~3% (still in pass1). The filesystem is ext3 running "e2fsck -C0 /dev/sda3" and about 3.7TB on an x86_64-based system with 4GB RAM. e2fsprogs is 1.41.9.

Hi List, Is there an easy way to get a count of the number of active socket connections, or even better, number of socket connections in the time_wait state? (Something lightweight... under /proc/sys/net/ipv4/? I'd like to avoid the impact of listing out all the connections a-la netstat.) Thanks! -Jeff

Hello! Please, help me, I''m totally lost choosing basic budget server for XEN. The variants are Sun (X2200 M2 or Sun X2250 M2) or maybe HP Proliant DL160 G5p. Or maybe some IBM server? Which X2200 configuration will perform better, two Opteron dual-core 22xx or single quad-core 23xx? Which one performing better nowadays, Opteron or Xeon? I know that 2-3 years ago Opteron was the

Reading the "waiting IOs" thread made me remember I have a similar problem that has been here for months, and I have no sulution yet. A single CentOS 5.2 x86_64 machine here is overloading our NetApp filer with excessive NFS getattr, lookup and access operations. The weird thing is that the number of these operations increases over time. I have an mrtg graph (which I didn't
