Forum for Lenovo LICO Product

Hi,

 

I am evaluating LiCO, I followed the installation document on CentOS 7.

I have some problems and questions, I searched in this forum and the Internet for LiCO forum or community but I didn't find any.

Could someone point me to the right direction.

 

Regards.

Re: Forum for Lenovo LICO Product

Hi @Wodel, welcome tothe Community,

 

Sorry if you are feeling a little sea sick with your topic being bounced around; I've just moved it back to where it originally was.

 

A separate board / forum for LICO is on the cards and likely to happen, unfortunately there is a lot happening at the moment and it fell a little below the radar, hopefully we can refocus and correct that in the near future.

 

Whilst we are doing what we have to do please work with @yixuanhuang, I'm certain he will be able to assist and when we have the board set up we can move this into it.

 

Thanks in advance and for your understanding,

 

 

Andy

Re: Forum for Lenovo LICO Product

Hi,

I am evaluating LiCO 5.3 on CentOS7

The plateforme is pretty small it is composed of :

1 - A disk array Lenovo ds4200
2 - A System X3550 M5 8869 acting as NFS Server, it is connected with two SAS cables the ds4200
3 - A System X3550 M5 8869 acting as a Master server
4 - A System X3550 M5 8896 acting as a login server
5 - Two chassis NextScale x360 M5 5456, one with 12 node the other with 4 nodes
6 - A 1Gb/s network switch used for : external and internal access, provisioning and bmc
7 - A Omni-path switch
8 - All nodes are connected to the omni-path switch including the NFS Server
9 - NFS shares are shared over RDMA

I configured slurm with three Partitions :
- The default : it contains only the compute nodes (NextScale)
- Extended : it contains the compute nodes and the login node
- Full : it contains the compute nodes the login node and the master node.
I used wight and cgroups to limite the use of resources on both the login and the master node.


I have some problems :
1 - Creating new ldap users using luseradd from CLI on the master node works without problem, the user and his home directory are created correctely, but when using LiCO's web interface, the user is created not his home directrory. I get a permission denied when using su or trying to login as the new user.

2 - The master node is offline on LiCO's web interface, looking on the log, it has something to do with confluent, I have an error message saying something like "the node is offline on confluent, discarding ganglia data", does this have something to do with serial connection? only the NFS and the master nodes were manually installed, the rest of nodes were auto-provisionned.

We're on holidays, for now I don't have access to the platforme to post the logs.

Could you please point to what logs do you need?

Regards.

Re: Forum for Lenovo LICO Product

1. lico will not create user's workspace when create new user.

When login via web, lico will create user's workspace using

'pam_mkhonedir.so' according to config file '/etc/pam.d/lico' .

When login via ssh, makesure you have already configured auto

makehomedir via authconfig.

Here is the command:

# Management node

$ sudo authconfig --useshadow --usemd5 \

--enablemkhomedir --disablecache --enablelocauthorize \

--disablesssd --disablesssdauth --enableforcelegacy \

--enableldap --enableldapauth --disableldaptls \

--ldapbasedn="${lico_ldap_domain_name}" \

--ldapserver="ldap://${sms_name}" \

--updateall

# Other node

$ sudo psh all authconfig --useshadow --usemd5 \ '

--enablemkhomedir --disablecache --enablelocauthorize \

--disablesssd --disablesssdauth --enableforcelegacy \

--enableldap --enableldapauth --disableldaptls \

--ldapbasedn="${lico_ldap_domain_name}" \

--ldapserver="ldap://${sms_name}" \

--updateall

 

2. Be sure your master node could ping the imm ip.

If you could not, maybe your have used NCSI.

Try change imm ip for master to 169.254.95.118

in /etc/lico/nodes.csv.

Re: Forum for Lenovo LICO Product

Hi,

 

1 - I will verify /etc/pam.d/lico to see if pam_mkhomedir.so is being loaded, and as I said I don't have the problem when creating the user from bash shell, the problem only appears when creating the user from LiCO's web console.

 

2 - The master node can ping it's imm, I am using the shared approach where eth0 is used both for provisioning/local network trafic and imm trafic and I'am using the same subnet 192.168.16.X/24 where the master IP is 192.168.16.7 and it's imm IP is 192.168.16.8. I can access the master's IMM web console, and I can check the master's power status for example using ipmitool, and finally I amd using the default login and password for all nodes.

  - Do I have to separate the imm trafic (use the physical imm port) for the master node?

 

 

Regards.

Re: Forum for Lenovo LICO Product

hello Paper, you can have a try to use dedicate IMM port (not shared port) or USB over lan (which will have 169.254.95.11x IP, device like enp0s29u1u1u5 in CentOS7, if that device is down, use ifup to active it). Then let us your result.
Thanks,
Eugene

Re: Forum for Lenovo LICO Product

Hi,

Sorry for the delay...

I used the physical IMM of the manager node directely and I enabled the enp0s20u13u5 interface

It seems to work now, the manager is up and chown correctly on the web-console and is accessible using the remote console connexion.

I did also verify the pam lico file and it contains this line :
session     optional     pam_mkhomedir.so skel=/etc/skel/ umask=0077

After making the changes to the IMM and solving the state problem, I did create a new user from the web-console and it's working no more permissions error.

I then disabled the enp0s20u13u5 and rebooted the master node, just to verify which of the changes I made did the trick, and it still working.

So using the physical IMM on the manager seems to be the solution to my problem.

 

Thank you again.


Regards.
