Re: Iscsi in the nautilus Dashboard

I posted to the ceph-iscsi github but Dillaman noted that 3.2 was version 10.  Which means that wouldn’t solve the issue with the version 9 requirement of the current 14.2.2 nautilus.   Paul noted 3.1 is “pretty broken”, soo which version is version 9?  Or should I hack/patch the dashboard in 14.2.2 to accept version 10 or 8?

Hi all,
That was not the most recent. This is it (3.2.4): https://2.chacra.ceph.com/r/ceph-iscsi/master/8a3967698257e1b49a9d554847b84418c15da902/centos/7/flavors/default/

Hi Brent,
You may want to have a look at the repos at shaman.ceph.com.
The latest (3.2.2) packaged version of Ceph iSCSI is located here:
https://4.chacra.ceph.com/r/ceph-iscsi/master/ff5e6873c43ab6828d3f7264526100b95a7e3954/centos/7/flavors/default/noarch/
You can also find related package repos for the tcmu-runner and ceph-iscsi-cli projects.
Regards, Kaspar

Version 9 is the fqdn stuff which was introduced in 3.1.
Use 3.2 as 3.1 is pretty broken.

I have a test cluster running centos 7.6 setup with two iscsi gateways ( per the requirement ).  I have the dashboard setup in nautilus ( 14.2.2 ) and I added the iscsi gateways via the command.  Both show down and when I go to the dashboard it states:

“ Unsupported `ceph-iscsi` config version. Expected 9 but found 8.  “

Both iscsi gateways were setup from scratch since the latest and greatest packages required for ceph iscsi install are not available in the centos repositories.  Is 3.0 not considered version 9?  ( did I do something wrong? ) Why is it called/detected as version 8 when its version 3?

I also wondering, the package versions listed as required in the nautilus docs(http://docs.ceph.com/docs/nautilus/rbd/iscsi-target-cli/)  state x.x.x or NEWER package, but when I try to add a gateway gwcli complains about the tcmu-runner and targetcli versions and I have to use the 
Skipchecks=true option when adding them.  

Another thing came up, might be doing it wrong as well:  
Added a disk, then added the client, then tried to add the auth using the auth command and it states: “Failed to update the client's auth: Invalid password”

Actual output:
/iscsi-target...erpix:backup1> auth username=test password=test
CMD: ../hosts/<client_iqn> auth *
username=test, password=test, mutual_username=None, mutual_password=None
CMD: ../hosts/<client_iqn> auth *
auth to be set to username='test', password='test', mutual_username='None', mutual_password='None' for 'iqn.2019-07.com.somgthing:backup1'
Failed to update the client's auth: Invalid username

Did I miss something in the setup doc?

Installed packages:
rtslib:  wget https://github.com/open-iscsi/rtslib-fb/archive/v2.1.fb69.tar.gz
target-cli: wget https://github.com/open-iscsi/targetcli-fb/archive/v2.1.fb49.tar.gz 
tcmu-runner: wget https://github.com/open-iscsi/tcmu-runner/archive/v1.4.1.tar.gz

configshell: wget https://github.com/open-iscsi/configshell-fb/archive/v1.1.fb25.tar.gz 

Other bits I installed as part of this:
yum install epel-release python-pip python-devel -y
yum groupinstall "Development Tools" -y
python -m pip install --upgrade pip setuptools wheel
pip install netifaces cryptography flask

Any helps or pointer would be greatly appreciated!
