NethServer Version: 6.8
I’m facing problems configuring the HA setup in Nethserver v6, I have found some inconsistencies regarding the commands and after (fixing them?) then my HA cluster cannot communicate with the members.
I’m following this guide:
In the steps of pcs commands, this one is stating error:
/usr/sbin/pcs -f /tmp/mycluster resource group add mysqlha drbdFS VirtualIP sym_var_lib_mysql sym_etc_my.pwd sym_root_.my.cnf var_lib_nethserver_secrets mysqld
After closer inspection I see some resources were not created in the guide, and other resources are not grouped in the mysqlha group:
sym_var_lib_mysql and var_lib_nethserver_secrets
Created but not included in group
After removing the resources not created from the command and including the sym_var_lib_asterisk, the group was created but members could not communicate with each other, were giving some “authentication refused” so I went and run:
passwd hacluster (to change the passwd of the hacluster of corosync)
pcs cluster auth ns1 ns2
after that corosync became online:
But ns2 could not sync with ns1 and resources were 0 in ns2, resources in ns1 were 8, those defined in the guide.
ns2 from ns1 status was UNCLEAN(OFFLINE)
I tried many different ways to manually sync the members but I couldn’t even find the corosync.conf file in /etc/corosync, maybe another file is being used for nethserver ha setup.
Any help at this point would be wonderful or at least any other guide for HA setup.
PD: at which point is the /dev/vdb1 partition referenced by DRBD?? the guide points to /dev/drbd/by-res/drbd00 but that doesn’t exist neither
