RE: [Xen-users] XCP - GFS - ISCSI

[Dave Scott <Dave.Scott@xxxxxxxxxxxxx>]

Hi,

Instead of creating an SR with ‘type=iscsi’, use ‘type=lvmoiscsi’ instead. This will create an LVM volume group on the iSCSI LUN where guest disks (VDIs) will be LVs.

The ‘iscsi’ SR type is intended for ‘LUN per VDI’ e.g. in a situation where you have data already on a LUN and you want to attach it directly to a guest. Normally XCP uses LVM to share one LUN amongst many guests.

Consider also setting your Pool default SR to point to the new shared storage:

# xe pool-param-set uuid=<uuid> default-SR=<sr-uuid> suspend-image-SR=<sr-uuid>

Cheers,

Dave

Hi everyone!

I have 2 hosts + 1 ISCSI device.

I want to create a shared storage repository and both hosts use together. I wont use NFS.

prepared  sr:

xe sr-create host-uuid=xxx content-type=user name-label=NAS1 shared=true  type=iscsi device-config:target=xxxx device-config:targetIQN=xxxx

hosts see the iscsi device:

scsi4 : iSCSI Initiator over TCP/IP
scsi 4:0:0:0: Direct-Access     NAS      iSCSI-VDISK      0    PQ: 0 ANSI: 4
sdb: unknown partition table

next step:

Should i make a GFS filesystem? (XCP doesn't include the GFS and clustering services)

 

Best Regards,

Menox
