All iSCSI IPs go down after removing 1 iSCSI target

Good <time_of_day>

In my 1.4 Lab, I was cleaning up some iSCSI targets I no longer needed.  Suddenly, on my Windows 2016, Hyper-V, VM 2012R2 went down...   Mystery...  Nah...  iSCSI target disconnected.  Cannot be pinged.

I tried all the other targets, same.  I had to stop and start all of them to be available again.

This is bad.  I need to be able to remove a target while the rest of the system goes chugging along.

Are you aware of this?  Is there a magic fix known on 1.5?   Am I alone in a dream world and it's a problem on my side ?

 

Thank you kindly one and all,  Love the product !

Hi Marc,

We did hit this problem and is fixed in version 1.5. When removing your first target, it will also remove secondary ips on the subnet.

To fix: add the following line to /etc/sysctl.conf  on every node:

ipv4.conf.all.promote_secondaries=1

then run

sysctl  --system

An upgrade to 1.5 will also add this line to your existing installation.

Glad you like the product.  /Hatem.

I so love it when a question as a solution !!!

Doesn't happen often.  😉  yeah...  I'm that good 😉

Thank you, our lab is going fairly well, other than crappy hardware issues.  back to fight with management to get real hardware !
