Hardware raid LSI Megaraid not working since Centos 6.6
Happy new year ! We have a SuperMicro server with a LSI MegaRAID 9260-4i controller. Since Centos 6.6 update (kernel 2.6.32-504), the controller doesn't initialize at boot. Reverting to kernel 2.6.32-431 allows server to boot fine. The server can't boot due to a bug in LSI megaraid module. Boot log ends by a lot of lines: RESET_GEN2: retry=xxx, hostdiag=a4 I tried Centos 6.6

Experience with Centos running off usb-stick(s)
Hi, I'm trying to build a redundant duo of firewalls/routers/gateways and I'm thinking about not putting any disks in them and instead using a usb-stick raid-1 as storage. Has anyone any experience with this? Since the machines will be running pretty much only iptables, conntrackd and keepalived there is not going to be a lot of disk activity going on and the plan is to do all the

Any alternatives for the horrible reposync
Hi, I'm currently trying to mirror a couple of yum repositories and the only tool that seems to be available for this is reposync. Unfortunately reposync for some inexplicable reason seems to use the yum config of the local system as a basis for its work which makes no sense and creates all kinds of problems where cache directories and metadata gets mixed up. Are there any alternatives? Some

VLAN issue
Do you need the whole configuration? On the switch end, we have the relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN. Seems - and acts - like a legitimate setup and works fine, except for this particular instance. Thanks. Boris. On Fri, Jan 23, 2015 at 8:54 PM, Dennis Jacobfeuerborn < dennisml at

VLAN issue
Andrew and Dennis are spot on. Their conclusions about your server being connected to an access port and not a trunk port would be my conclusion as well.

Kickstart and volume group with a dash in the name
Hi, I'm trying to setup the provisioning of new OpenStack hypervisors with cinder volumes on them. The problem is that kickstart doesn't allow dashed in volume group names? I tried this: volgroup cinder-volumes --pesize=4096 pv.02 and this: volgroup cinder--volumes --pesize=4096 pv.02 but in both cases I end up with a volume group named "cindervolumes" on the system.

Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
The HBA is an HP H220. We haven?t really benchmarked individual drives ? all 12 drives are utilized in one RAID-10 array, I?m unsure how we would test individual drives without breaking the array. Trying ?hdparm -tT /dev/sda? now ? it?s been running for 25 minutes so far? Kelly On 2016-05-25, 2:12 PM, "centos-bounces at centos.org on behalf of Dennis Jacobfeuerborn"

[OT/HW] hardware raid -- comment/experience with 3Ware
Greetings, I am looking for a hardware raid card that supports up to 4 SATA II hard disks with hot swap (compatible raid cage) I have short listed two LSI/3Ware cards: 1. 9750-4i 2. 9650SE-4LPML Both appear to be well supported in Linux. I would appreciate your personal experience with the CLI tools provided by LSI. Can they be configured to send email for disk failures or SMART errors? Is

Hardware raid health?
I just had an IBM in a remote location with a hardware raid1 have both drives go bad. With local machines I probably would have caught it from the drive light before the 2nd one died... What is the state of the art in linux software monitoring for this? Long ago when that box was set up I think the best I could have done was a Java GUI tool that IBM had for their servers - and that seemed like
