SOLVED iSCSI service fails to start

[ocalvo]

I am trying to configure a new target, after running the wizard if I stop the service, it wont start again.

How can I run the service in interactive mode?

Here is the output of var/log/meesages:

which software version?

So the service was running after wizard,,, but after stopping it, it doesn't restart? Being very clear about what worked and what did not helps everyone

This is correct. I figured out what the problem was. I will post details here in a bit.

Using 'TrueNAS-SCALE-21.04-ALPHA.1'

When running the wizrd it allow me to use dots "." in the name of the target, this generated a `/etc/scst.conf` that looks like:
```
HANDLER vdisk_blockio {
DEVICE iscsi.server.systemdisk {
filename /dev/zvol/SystemPool/VMs/Server/SystemDisk
blocksize 4096
read_only 0
usn d0f97c38380317a
naa_id 0x6589cfc000000558c5530253583ade57
prod_id "iSCSI Disk"
t10_vend_id TrueNAS
t10_dev_id d0f97c38380317a
}

}

TARGET_DRIVER iscsi {
enabled 1

TARGET iqn.2005-10.org.freenas.ctl:iscsi-server-systemdisk {
enabled 1
per_portal_acl 1

GROUP security_group {
INITIATOR *\#*

LUN 0 iscsi.server.systemdisk
}
}
}
```

Changing `iscsi.server.systemdisk` to `iscsi-server-systemdisk` resolved the issue.
Otherwise dmesg shows an error saying the a device has an invalid name with "dot"

Glad you solved..... there are so many ways that there can be misconfiguration... which is why we ask that these problem statements include all the detail.

in addition to what @morganL said, this is definately something that needs a Jira ticket because the UI should allow things like these that break.

Thanks, 20s page loading times on JIRA make it hard for me to file things in these cases :\
