In many ways it is more convenient to use than KVM and very, very stable.

I'd also add that the o/p said this was what they used at his job, and I find it highly unlikely that he's going to be able to convince management to move to a VM system that they're not familiar with, esp. when all of his co-workers, and presumably management, run Windows. Given that, I think the answers he needs are how to deal with VMware ESXi as it is. And yes, I'm well aware that ESXi is a modified version of, mmm, is it still RHEL 3, or have they gone up yet? mark

large SCSI RAID, replacing server
by Joseph Spenner 10 Sep '13

10 Sep '13

I have a system running CentOS 6.3, with a SCSI attached RAID: http://www.raidweb.com/index.php/2012-10-24-12-40-09/janus-ii-scsi/2012-10-… For disaster recovery purposes, I want to build up a spare system which could take the place of the server hosting the RAID above. But here's what I see: # fdisk -l /dev/sdc WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sdc: 44004.7 GB, 44004691814400 bytes 255 heads, 63 sectors/track, 5349932 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 524288 bytes / 524288 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 1 267350 2147483647+ ee GPT Partition 1 does not start on physical sector boundary. # But here's the partitions I have: # df -k |grep sdc /dev/sdc1 15379809852 8627488256 6596071608 57% /space01 /dev/sdc2 6248052728 905001184 5279574984 15% /space02 /dev/sdc5 8175038780 2418326064 5673659088 30% /space03 /dev/sdc4 6248052728 1444121916 4740454252 24% /space04 /dev/sdc3 6248052728 1886640284 4297935884 31% /space05 # How can I build up a new system to be ready for this existing RAID?

Getting a do_IRQ: xx.xxx No irq handler for vector (irq -1), any ideas?
by Howard Leadmon 10 Sep '13

10 Sep '13

I setup a CentOS 6 server to use with KVM/QEMU, and I am getting the following error a good bit, granted it doesn't seem to be causing any trouble. I figured I would post and see if anyone has any ideas on the issue, or if I can just dismiss it. If I look at my logging/dmesg, I see: do_IRQ: 19.217 No irq handler for vector (irq -1) do_IRQ: 3.178 No irq handler for vector (irq -1) do_IRQ: 19.179 No irq handler for vector (irq -1) do_IRQ: 3.220 No irq handler for vector (irq -1) do_IRQ: 18.213 No irq handler for vector (irq -1) do_IRQ: 18.79 No irq handler for vector (irq -1) do_IRQ: 3.144 No irq handler for vector (irq -1) do_IRQ: 18.201 No irq handler for vector (irq -1) do_IRQ: 18.124 No irq handler for vector (irq -1) do_IRQ: 18.160 No irq handler for vector (irq -1) do_IRQ: 19.208 No irq handler for vector (irq -1) do_IRQ: 3.147 No irq handler for vector (irq -1) do_IRQ: 18.117 No irq handler for vector (irq -1) do_IRQ: 3.103 No irq handler for vector (irq -1) do_IRQ: 3.169 No irq handler for vector (irq -1) do_IRQ: 18.201 No irq handler for vector (irq -1) The machine is an HP ProLiant DL580-G5 series with 4x Xeon hexacore processors installed, along with 32G of RAM at this time. I am happy to post more dmesg output if it's of any help. Kernel version is: 2.6.32-358.18.1.el6.x86_64 --- Howard Leadmon

mouse "stuck"
by Michael Hennebry 08 Sep '13

08 Sep '13

Sommetimes, for no apparent reason, my mouse cursor will become four arrows and suddenly I cannot do anything with my desktop. I can move the cursor and that is it. Clicking has no effect. cnrtl-alt-F6 gave me another virtual console from which I could post this. Other rebooting, how do I fix this? I'm running xfce on 6.2. -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "On Monday, I'm gonna have to tell my kindergarten class, whom I teach not to run with scissors, that my fiance ran me through with a broadsword." -- Lily

yum problem
by Phil Dobbin 08 Sep '13

08 Sep '13

Hi, all. I'm experiencing a problem with Yum. When I call 'sudo yum update' it tells me that it can't find any mirrors & after doing a 'sudo yum clean all' it just informs me it can't find any base repo & quits. This is on a brand new installation of CentOS 6.2 x86_64. I suffered the same problem with Fedora 19 too. I have several Ubuntu & Mac OS X machines that suffer no network connection problems & I can connect to the InterWeb just fine (via two HP Procurve 2426s). Any help appreciated. Cheers, Phil...
