Hi, we would like to establish a small Lustre instance and for the OST planning to use standard Dell PE1950 servers (2x QuadCore + 16 GB Ram) and for the disk a JBOD (MD1000) steered by the PE1950 internal Raid controller (Raid-6). Any experience (good or bad) with such a config ? thanxs, Martin

Is anybody here monitoring Dell SAS6/iR RAID health? I have a mix of CentOS 5.9 and 6.3 installs on the PE1950s. I'm finding drivers and Megaraid Storage Manager downloads via LSI's site, but I'd prefer not to install a bunch of crapware. All I need is the proper LSI daemon which exports info via SNMP. I've used check_sasraid_megaraid Nagios script [0] in the past for PERC5i and PERC6i co...

Hi, I've installed CentOS 5 on a Dell pe1950 with 2 dual port NICS. One of the NIC is an Intel and use the e1000 module. The problem is when the server is rebooted it does no asign the ethx name to the NICs, instead the so assign something like _dev377362... so i dont have networking on the server. Any ideas what is happening and how to...

...t; net.ipv4.ip_forward = 1 > > Should explain why you IP on the bridge works but not on the vms. > First, thanks for the reply and excellent suggestion.? Yeah, I thought about that, and while it's not specifically defined in /etc/sysctl.conf or /etc/sysctl.d/*, if I: [root at c8-kvm-pe1950-1 ~]# cat /proc/sys/net/ipv4/ip_forward 1 It shows as being defined to 1.? I'm going to try adding to sysctl.conf and see if that makes any difference, though.

...ts. I am getting a pretty bad hum on the line during a call. I have checked the Telco side of the 66 block and there is no hum there so it's my problem to fix. I have tried to lower the gain but that reduces the call volume to much. Where else should I be looking?

We have a 3TB external USB drive that I am trying to attach to some CentOS5 servers. I have tried an older Dell PE1950 and a newer R310 but neither one seems to be able to read the drive. It works no problem on windows servers/workstations and I was able to format with NTFS. I know there are different methods for formatting large disks but this one doesn't even seem to show up as a /dev/ device. I supplied...

...eople's experiences are WRT systems becoming unresponsive (unable to ssh in, etc) for brief periods of time when a large amount of IO is being performed. It's really starting to cause a problem for us. We're on Dell PowerEdge 1955 blades - but this same issue has caused us problems on PE1950, PE1850, PE1750 servers. We're running Centos 4.5 right now. I know Centos 5 includes ionice, more io scheduler/elevator selections like deadlock/etc. Perhaps that would fix this issue. We're running the latest PERC firmware. The specific issue I'm referring to at this point is on a...

Hello gentlemen! I just experienced this weird thing: I have 2 machines (one is a Dell Pe1950 with 2 Xeon 5130, the other is a Fujitsu RX200S6 with 2 Xeon E5645), both run CentoOS 5.6, the DELL has the 2.6.18-238.9.1.el5 while the Fujitsu runs the 2.6.18-238.12.1.el5 kernel. But when I try to do a virsh create with this script <domain type='kvm'> <name...

The server is Dell PE1950 running dovecot (1.0.7-2.el5) as supplied with Centos 5.2 (~Redhat AS 5.2) in 64 bit mode. I've upgraded the server from 4 to 8GB of RAM, and from a dual core 1.5Ghz xeon, to a quad core 1.5GHz xeon, and this does not seem to help. The following settings were increased by me to try and stop...

Syslinux 3.85 is a bug fix and minor new feature release. The biggest change is undoubtedly that gPXELINUX is now considered feature complete, and should be able to be a drop-in for PXELINUX for all uses. Special thanks to Intel Corporation, my current employer, for their support for my Syslinux work. Changes in 3.85: * gPXELINUX: updated to gPXE 1.0.0. gPXELINUX can now do NBP

Dear all, I will setup soon an Infortrend iSCSI SAN device with a raid6 volume and a DELL PE1950 (8 VMs) with a Qlogic iSCSI HBA (server to be duplicated at later time for redundancy). My priorities are: 1) VMs on the iSCSI SAN in order to boot them also by another server if the first one fails 2) performances 3) live migration is a non mandatory option (i.e. I can suffer to shutdown ma...

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,

James' point isn't the hardware cost, it's the people cost for retraining. In many ways the Fedora treadmill is easier, being that there are many more smaller jumps than the huge leap from C6

Hey, everyone, I''m having some issues with a Xen DomU right related to performance. We have an application that cross-compiles a Linux distribution from scratch for embedded systems. We''re attempting to run this application inside a Xen DomU (paravirtualized, modified guest kernel), and the performance is really bad. The culprit seems to be high I/O wait times related to the
