[Pkg-libvirt-maintainers] Bug#885334: libvirt-daemon: Cannot start iSCSI storage pool : "iscsiadm failed new mode for target"

[Gilles Mocellin]

Package: libvirt-daemon
Version: 3.10.0-1
Severity: normal

Dear Maintainer,

I always had problems with iSCSI storage and virt-manager /  libvirt.
I have storage pool, which are not auto-started, because I dont't use
them everytime.

There is :
- an iSCSI storage pool
- a LVM storage pool, based on the previous iSCSI device
VMs drives are thin LV.

Until last open-iscsi update, I had to start the pool twice : error on
first try, then it works.
Now, it doesn't start anymore.

I have a new error, which is also visible in the logs :

$ grep libvirt /var/log/syslog
Dec 26 10:59:48 guitare libvirtd[1495]: 2017-12-26 09:59:48.721+0000:
1623: error : virISCSINodeNew:489 : internal error: iscsiadm failed new
mode for target 'iqn.2000-01.com.synology:batterie.vms' with status '6'

Idem with virsh :

virsh # pool-list --all
 Name                 State      Autostart 
-------------------------------------------
 default              active     yes       
 iscsivms             inactive   no        
 iso                  inactive   no        
 vgvms                inactive   no        

virsh # pool-start iscsivms
error: Failed to start pool iscsivms
error: internal error: iscsiadm failed new mode for target 'iqn.2000-01.com.synology:batterie.vms' with status '6'

Some informations on my pool :

virsh # pool-info iscsivms
Name:           iscsivms
UUID:           18c88798-0eb1-4500-a0e7-04e563019af8
State:          inactive
Persistent:     yes
Autostart:      no

virsh # pool-dumpxml iscsivms
<pool type='iscsi'>
  <name>iscsivms</name>
  <uuid>18c88798-0eb1-4500-a0e7-04e563019af8</uuid>
  <capacity unit='bytes'>0</capacity>
  <allocation unit='bytes'>0</allocation>
  <available unit='bytes'>0</available>
  <source>
    <host name='batterie' port='3260'/>
    <device path='iqn.2000-01.com.synology:batterie.vms'/>
  </source>
  <target>
    <path>/dev/disk/by-path</path>
  </target>
</pool>

If I log manually, it works :

# iscsiadm --mode node --targetname iqn.2000-01.com.synology:batterie.vms --portal batterie --login
Logging in to [iface: default, target: iqn.2000-01.com.synology:batterie.vms, portal: 10.0.0.3,3260] (multiple)
Login to [iface: default, target: iqn.2000-01.com.synology:batterie.vms, portal: 10.0.0.3,3260] successful.

Thanks for your attention,
Gilles.
