pool-refresh on iSCSI pools does not actually rescan the bus
Hi,
When I add a new LUN on an iscsi target and then issue a pool-refresh command
on the respective storage pool in libvirt, libvirt will not find the new lun
(or notice if luns have been removed).
I'm using a Dell PowerVault MD3200i iSCSI Array to hold the volumes for
virtual servers in libvirt. In libvirt, I have defined the storage pool as
this:
<pool type='iscsi'>

tgtadm and exported iscsi volumes
Out of haste I decided for the first time not to pull down and compile
iet to export a single volume to a windows machine so I just used tgtd.
Well, much more time later than otherwise would be the case had I used
iet, when I mount the volume on the windows ini, it can't find and install
a driver? WTF?
This have anything to do with the tgtd being a tech preview:)
Anybody seen this b4?

iSCSI Question
Hey everyone,
Is anybody aware of a /true/ active/active multi-head and multi-target
clustered iSCSI daemon?
IE:
Server 1:
Hostname: host1.test.com
IP Address: 10.0.0.1
Server 2:
Hostname: host2.test.com
IP Address: 10.0.0.2
Then they would utilize a CLVM disk between them, let's call that VG "disk"
and then directly map each LUN (1,2,3,4,etc) to LV's named 1,2,3,4,... and

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.

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.

This is pretty epic if true.
I'm installing some Fail 2008r2 now to check.
Is your hypervisor running CentOS 6 or 7?
