Cluster configuration scst

[Roman Drovalev]

Hello.

I want to configure cluster scst. I do the configuration according to the instructions - https://github.com/quantum/esos/wiki/42_Cluster_Configuration

When entering the command: 

crm configure primitive p_scst ocf:esos:scst params alua="true" device_group=”esos” local_tgt_grp=”local” remote_tgt_grp=”remote” op monitor interval=”10” role="Master" op monitor interval=”20” role="Slave" op start interval="0" timeout="120" op stop interval="0" timeout="90"

this error comes out:

ERROR: Relax-NG validity error : Element op failed to validate attributes

Relax-NG validity error : Extra element operations in interleave

       operations (6): Element primitive failed to validate content

       primitive (9): Element resources has extra content: primitive

Errors found during check: config not valid

WARNING: p_scst: interval in monitor_Slave must be unique

Do you still want to commit (y/n)? n

Why does the error appear? How to configure this cluster scst for FC target?

Thank.

Hi,

Do you get that message when attempting to commit a shadow CIB? Or are
you editing the cluster config manually (eg, crm configure edit)?
Cluster configuration is really dependent on your desired setup and
back-end storage topology.

Hello. 

I do these actions as described in the instructions (I substitute my wwn)

On the first host, using the shell (Interface -> Exit to Shell):

/etc/rc.d/rc.scst start
scstadmin -add_dgrp esos
scstadmin -add_tgrp local -dev_group esos
scstadmin -set_tgrp_attr local -dev_group esos -attributes group_id=1
scstadmin -add_tgrp_tgt 21:00:00:e0:8b:9d:74:49 -dev_group esos -tgt_group local
scstadmin -set_ttgt_attr 21:00:00:e0:8b:9d:74:49 -dev_group esos -tgt_group local -attributes rel_tgt_id=1
scstadmin -add_tgrp remote -dev_group esos
scstadmin -set_tgrp_attr remote -dev_group esos -attributes group_id=2
scstadmin -add_tgrp_tgt 21:00:00:1b:32:01:6b:11 -dev_group esos -tgt_group remote
scstadmin -set_ttgt_attr 21:00:00:1b:32:01:6b:11 -dev_group esos -tgt_group remote -attributes rel_tgt_id=2
/etc/rc.d/rc.scst stop

On the second host, using the shell (Interface -> Exit to Shell):

/etc/rc.d/rc.scst start
scstadmin -add_dgrp esos
scstadmin -add_tgrp local -dev_group esos
scstadmin -set_tgrp_attr local -dev_group esos -attributes group_id=2
scstadmin -add_tgrp_tgt 21:00:00:1b:32:01:6b:11 -dev_group esos -tgt_group local
scstadmin -set_ttgt_attr 21:00:00:1b:32:01:6b:11 -dev_group esos -tgt_group local -attributes rel_tgt_id=2
scstadmin -add_tgrp remote -dev_group esos
scstadmin -set_tgrp_attr remote -dev_group esos -attributes group_id=1
scstadmin -add_tgrp_tgt 21:00:00:e0:8b:9d:74:49 -dev_group esos -tgt_group remote
scstadmin -set_ttgt_attr 21:00:00:e0:8b:9d:74:49 -dev_group esos -tgt_group remote -attributes rel_tgt_id=1
/etc/rc.d/rc.scst stop

Hello.

I also don’t understand! To configure ALUA correctly, should the local and remote groups with the same name or not? 

According to the documentation - with the same name. 

But in my opinion it does not work!

Tanks.

Hi Roman,

Read through this document for more detailed information than what's
available on the ESOS wiki page:
https://sourceforge.net/p/scst/svn/HEAD/tree/branches/3.3.x/scst/README

In particular, start reading at the section beginning with "ALUA Support".

Hello.

Thanks, read it. I configured everything through TUI works. BUT not a single example from the documentation for a cluster does not work!

1.) I liked the idea from Zachlod.

What kind of cluster commands does he mean by the following?

crm_attributes ?

node 1: alpha

attributes nodetype=fctarget targetports="21:00:00:24:ff:60:d0:10,21:00:00:24:ff:60:d0:11" 

node 2: beta 
attributes nodetype=fctarget targetports="21:00:00:1b:32:0b:52:75,21:01:00:1b:32:2b:52:75"

2.) An example of my configuration in the picture.

Is it possible to implement this and how?

There are no specific examples in the documentation for clusters.

Please, help.
