4.5. Testing the Resource Configuration

If the Samba configuration was successful, you should be able to mount the Samba share on a node in the cluster. The following example procedure mounts a Samba share.
  1. Add an existing user in the cluster node to the smbpasswd file and assign a password. In the following example, there is an existing user smbuser. 
    [root@z1 ~]# smbpasswd -a smbuser
New SMB password:
Retype new SMB password:
Added user smbuser

  2. Mount the Samba share: 
    [root@z1 ~]# mkdir /mnt/sambashare
[root@z1 ~]# mount -t cifs -o user=smbuser //198.162.1.151/public /mnt/sambashare
Password for smbuser@//198.162.1.151/public:  ********

  3. Check whether the file system is mounted: 
    [root@z1 ~]# mount | grep /mnt/sambashare
//198.162.1.151/public on /mnt/sambashare type cifs (rw,relatime,vers=1.0,cache=strict,username=smbuser,domain=LINUXSERVER,uid=0,noforceuid,gid=0,noforcegid,addr=10.37.167.205,unix,posixpaths,serverino,mapposix,acl,rsize=1048576,wsize=65536,echo_interval=60,actimeo=1)
    Copy to Clipboard Toggle word wrap
To check for Samba recovery, perform the following procedure.
  1. Manually stop the CTDB resource with the following command: 
    [root@z1 ~]# pcs resource debug-stop ctdb
    Copy to Clipboard Toggle word wrap
  2. After you stop the resource, the system should recover the service. Check the cluster status with the pcs status command. You should see that the ctdb-clone resource has started, but you will also see a ctdb_monitor failure. 
    [root@z1 ~]# pcs status
...
Clone Set: ctdb-clone [ctdb]
     Started: [ z1.example.com z2.example.com ]
...
Failed Actions:
* ctdb_monitor_10000 on z1.example.com 'unknown error' (1): call=126, status=complete, exitreason='CTDB status call failed: connect() failed, errno=111',
    last-rc-change='Thu Oct 19 18:39:51 2017', queued=0ms, exec=0ms
...
    Copy to Clipboard Toggle word wrap
    To clear this error from the status, enter the following command on one of the cluster nodes: 
    [root@z1 ~]# pcs resource cleanup ctdb-clone
    Copy to Clipboard Toggle word wrap
