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

Package: xen-hypervisor-3.4-amd64 and linux-image-2.6.32-5-xen-amd64 Version: 3.4.3-1 and 2.6.32-15 Hello all, GRUB-PC does not automatically populate Xen related parameters in /boot/grub/grub.cfg so I added them manually (see below). All the packages involved on my Dell PowerEdge R710 running Debian GNU/Linux Squeeze AMD64 are from the Squeeze repository. There are four (4) 1TB SATA HDD

I may have asked about this before, but I can't find any records of so doing in my saved mail (which includes almost everything I ever read or write): All of a sudden, I am not getting flash drives automatically mounted in CentOS 5.3 with GNOME - they are recognized by the hardware, but there seems to be a (new?) problem with the maps. Here's the tail end of dmesg: usb 1-10: new high

Basically the issue comes down to my Volume Groups not being found by this initrd, causing good ole kernel panic. initrd-2.6.12.6-xen3_12.1_rhel4.1.img [root@xen01 lvm]# uname -a Linux xen01.inside.***.com 2.6.9-22.0.2.ELsmp #1 SMP Thu Jan 5 17:13:01 EST 2006 i686 i686 i386 GNU/Linux [root@xen01 lvm]# cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 2) Everything

Hi, I just came across this box [0] (McKay Creek). Seems to be exceptional building material for ZFS based NAS/iSCSI unit. I especially liked the two extra system disks hidden inside the box ! Any one have an experience with these ? [0] http://www.intel.com/design/servers/storage/ssr212mc2 -- Regards, Cyril

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

I've been having an extremely hard time using the on board SATA controller on my nvidia based board. I have two 160gig Maxtor SATA drives attached to the on board controller, setup as software raid0. The problem is the array is extremely unreliable, where I'm getting constant I/O errors like: sd 0:0:0:0: SCSI error: return code = 0x00040000 end_request: I/O error, dev sda, sector

Hi, we are currently working on getting windows working on your xen servers. but we are facing a severe problem where dom0 and all domus hang for 1-5 seconds from time to time. we think it is probably because of disk i/o, because top sometimes says 100% wa (waiting on io) during the hang. dom0 has cpu 0 for exclusive use and the windows vms use cpu 1 to 7. should we give dom0 more than once

I just installed CentOS 5 on a computer. On boot, I get the a error message, related to 2 SATA disks. These errors did NOT appear on version 4.4 with the EXACT same hardware. Despite the error messages, the disks seem to be working with no problems. Could someone please tell me what these error are and if there is some known way to prevent them? I searched the Net for these errors and they seem

So I'm working with the iSCSI Initiator and an EqualLogic SAN. I'm not sure when this might have happened, but it appears that the /dev/sdc device is missing, yet the /dev/sdc1 partition exists AND is mountable. Is there a method to re-create the /dev/sdc device? I cannot dd or fdisk it, obviously, but I can mount the /dev/sdc1 partition and it works just fine. Not having the /dev/sdc

Hi, all! I want to change current RHEL 4.0 ES into CentOS 4.2 on Sun X4100 server. The server has SAS SCSI based two 2.5" hard disks. I could only install RHEL 4.0 Update 1 because the server is equipped with RHEL 4.0 Update 1's device driver only. I've included below the boot process messages concerned with SCSI controller. If it's possible for me to install CentOS 4.0 on my

Hi Alex, I've been playing around with VFIO and megasas (of course). What I did now was switching between VFIO and 'normal' operation, ie emulated access. megasas is happily running under VFIO, but when I do an emergency stop like killing the Qemu session the PCI device is not properly reset. IE when I load 'megaraid_sas' after unbinding the vfio_pci module the driver
