Hi, im trying to add my third storage drive but it seems like something is wrong.
When i add it and have synced it up with drbd and i see it in sync on both servers (up to date) i try to restart my nodes and when they come back up they cant connect to eachother anymore and the pool is "gone" when i type ha-cfg status it reports nothing on the pool uuid line and i cant get it back up until i comment out my new changes i just made in all the config files and reboot it again.

/etc/iscsi-ha/iscsi-ha.conf
DRBD_RESOURCES=iscsi1:iscsi2:iscsi4


/etc/drbd.conf
resource iscsi4 {
protocol C;
net {
after-sb-0pri discard-zero-changes;
after-sb-1pri consensus; cram-hmac-alg sha1;
shared-secret PUTyourSECREThere;
}
on nfnode01 {

disk /dev/sdd;
address 10.10.10.1:7791;

}
on nfnode02 {
device /dev/drbd4;
disk /dev/sdd;
address 10.10.10.2:7791;

}
}


/etc/tgt/targets.conf

/etc/lvm/master/lvm.conf and /etc/lvm/lvm.conf
filter = [ "r|/dev/sdb|", "r|/dev/drbd1|", "r|/dev/sdc|", "r|/dev/drbd2|", "r|/dev/sdd|", "r|/dev/drbd4|" ]


it syncs fine (says up to date on it), i can detach and attach it manualy without any issues.
Have anyone had this issue before?


I also want to thank you all that works with HA-Lizard, we have used it for 2.5 years now (since i created my account here) and it still works flawless for us.
Is it possible to make a donation to HA-Lizard directly? would need an invoice for it, send me a PM if possible.

Hi Alexander,

If you are trying to manage 3 storage devices, it looks like the configuration files are missing some data (or maybe you truncated the files for posting here only??)

drbd.conf should have 3 resource sections.

also, targets.conf should have a backing store for each of the storage devices.. working example is below

<target iqn.2015.com.halizard:noSAN>
<backing-store /dev/drbdresource1>
lun 10
</backing-store>

<backing-store /dev/drbdresource2>
lun 20
</backing-store>
</target>

<backing-store /dev/drbdresource3>
lun 30
</backing-store>
</target>

Hi Salvatore,

Yes that is correct, i truncated it for the forums.
I do already run 2 storage devices with success.


/etc/tgt/targets.conf

<target iqn.2015.com.halizard:noSAN>
<backing-store /dev/drbd1>
lun 10
</backing-store>

<backing-store /dev/drbd2>
lun 20
</backing-store>
</target>

<backing-store /dev/drbd4>
lun 30
</backing-store>
</target>

All of the config files look OK. We need some debug in order to see what is going on.

Are you able to reproduce the issue and send a copy of /var/log/user.log. You can PM it to me by replying to the email I sent yesterday (assuming you received it).
