[libvirt-users] pool-refresh on iSCSI pools does not actually rescan the bus

[Guido Winkelmann]

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'>
  <name>iscsi01</name>
  <uuid>52eb9c59-a7ac-a4e8-a26e-7ca112f0dd70</uuid>
  <capacity>85899345920</capacity>
  <allocation>85899345920</allocation>
  <available>0</available>
  <source>
    <host name='10.3.1.15'/>
    <device 
path='iqn.1984-05.com.dell:powervault.md3200i.6782bcb0000859f3000000004d3eec7d'/>
  </source>
  <target>
    <path>/dev/disk/by-id</path>
    <permissions>
      <mode>0700</mode>
      <owner>-1</owner>
      <group>-1</group>
    </permissions>
  </target>
</pool>

If I add a new LUN on the iSCSI array, and then issue the command "pool-
refresh iscsi01", followed by "vol-list iscsi01" in virsh, the list does not 
contain the new volume. The only workaround I have found so far for this is to 
manually log in to the host server as root, do "iscsiadm -m discovery -t 
sendtargets -p 10.3.1.15" and then issue the pool-refresh command in libvirt.

Libvirt is libvirt-0.8.3-4.fc14.x86_64 on Fedora 14.

Is this supposed to work like this? If not, will a newer version fix that 
problem?
