Hello all,

I got it working just fine so far on all lab tests, but one thing a couldn't find in here or other post related to using a dedicated storage network other then managemente network. Can it be modified? In this lab, we have 2 hosts with 2 network cards each, one for mgmt and vm external traffic, and the second should be exclusive for storage, since is way faster.

We are using a separate network in our lab. What we do is this:

1. get the node list from the running controller via

linstor node list

2. take a look at the node interface list via

linstor node interface list <node name>

3. modify each nodes interface via

linstor node interface modify <node name> default --ip <ip>

4. check addresses via this

linstor node list

Hope that helps!

Another option:

1. Create additional interface

linstor node interface create <node name> storage_nic <ip>

2. Set preferred interface for each node

linstor node set-property <node name> PrefNic storage_nic

hosts previous was used with VMware VSAN,
I have nvme and HDD disks in the same hosts.

I am new in LINSTOR/DRBD/XOSTOR.

What will be better, use LVM on top of mdm software raid or not?

If a disk fails on one of the servers, will there be an automatic failover to the remaining replica?
Will there be a break in this case?
Will it start writing a new replica to the remaining host?

Hi,

1. is it possible to create more then one linstor SR in pool?

I have this error:
Error code: SR_BACKEND_FAILURE_5006
Error parameters: , LINSTOR SR creation error [opterr=LINSTOR SR must be unique in a pool],

2. Also, is it possible to have hybrid volume ssd+hdd (cache/autotiring) ?

If delete CloudConfigDrive, then it will try to search configuration disk every time and break network config.
You can just remove drive and create empty file /etc/cloud/cloud-init.disabled
It will disable cloud-init.

@Danp I will try to install latest updates

@stormi yes.

@stormi
fixed memory

@Danp

thank you for your reply.
this is test environment is working on vmware virtual machines with virtualization support enabled.
XCP configuration attached.

VM - Debian 10. Tools installed.

Every time during migration between 2 similar hosts in the same pool, VM is restarted.
How to fix it?
