TOPIC: Add New Storage to Existing HA Lizard Cluster

Add New Storage to Existing HA Lizard Cluster 8 months 2 weeks ago #1617

Hi,
I am evaluating HA Lizard for my next setup. Can you explain how to add new storage to existing HA Lizard cluster?
Right now I am still running on my lab using KVM virtualization to run two XenServer 7.4 hosts using halizard_nosan_installer_2.1.4. Thanks.

The following files require changes to add additional storage:
Lvm-update filter
/etc/lmm/lvm.conf
/etc/lvm/master/lvm.conf

Iscsi target config - add new target
/etc/tgtd.conf

Drbd - add new resource
/etc/drbd.conf

Iscsi-ha - add new resource
/etc/iscsi;ha-iscsi-ha.conf

Also, you will need to initialize the new drbd resource for this to work. All of the steps are documented in the reference design document you can download from the Web site. Or, you can follow this post with specific examples from other users that are confirmed working.

Hi Salvatore,
Which is this the correct way for /etc/drbd.conf? Adding new volume to existing resource or adding new resource. My drbd.conf below is not working:
#############
global { usage-count no; }
common { syncer { rate 100M; } }
resource iscsi1 {
protocol C;
net {
after-sb-0pri discard-zero-changes;
after-sb-1pri consensus; cram-hmac-alg sha1;
shared-secret PUTyourSECREThere;
}
volume 0 {
device /dev/drbd1;
disk /dev/sda3;
meta-disk internal;
}
volume 1 {
device /dev/drbd2;
disk /dev/sdb;
meta-disk internal;
}
on masterxs {
address 10.10.10.1:7789;
}
on slavexs {
address 10.10.10.2:7789;
}
}

Add a new resource. You can copy the default resource "iscsi1" and change the relevant parts, ie. resource name, disk, device, etc..

Once done (assuming the other required changes to LVM, TGT and iSCSI-HA have been completed), you would add a new iSCSI SR in XenServer to introduce the new storage to the pool.
