iscsi-ha-ERROR-/etc/iscsi-ha/init/iscsi-ha.mon: 6 months 2 days ago #2752

I am getting this error every hour on my new two node nosan HALIZARD cluster:

However, if I am checking "/etc/iscsi-ha/iscsi-ha.sh: line 233:" I could not find `UpToDate/UpToDate'

any Idea how to solve this problem?

That is off. The error occurs when trying to unset the variable "D_STATE" which is definitely set since the line immediately above the error is logging out the value of D_STATE.

It could be that the parent process (iscsi-ha.mon) has lost scope into its child process.

Can you try restarting the service to see whether the error goes away?

service iscsi-ha restart

service iscsi-ha restart

No, it does not change anything. The error repeats every 10 seconds, not every hour.
On my old Xenserver 6.5 pool I see only a different error message related to ha-lizard.mon:
[root@IT1XENMASTER1 ~]# tail -f /var/log/user.log |grep ERROR

Thanks for testing. After further thought, this appears to be a bug. In the code we are unsetting the variable D_STATE incorrectly.

We should be unsetting the variable definition. Instead the code is unsetting the expanded variable which is throwing the error.

You can verify this by changing line 233 from "unset $D_STATE" to "unset D_STATE" (simply remove the $), then restart.

Once you've confirmed, I can release a new RPM. Thanks for reporting this.

I can confirm that the change work as expected:

File: c/iscsi-ha/iscsi-ha.sh: line 233:
#               unset $D_STATE bug changed on 21.09.2022 into:
                unset D_STATE

In the same file on line 213 you will find also another unset statement, which seems to be also wrong:
        unset $CONNECTION
