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.
- Add an existing user in the cluster node to the
smbpasswdfile and assign a password. In the following example, there is an existing usersmbuser.[root@z1 ~]#
smbpasswd -a smbuserNew SMB password: Retype new SMB password: Added user smbuser - Mount the Samba share:
[root@z1 ~]#
mkdir /mnt/sambashare[root@z1 ~]#mount -t cifs -o user=smbuser //198.162.1.151/public /mnt/sambasharePassword for smbuser@//198.162.1.151/public: ******** - 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)
To check for Samba recovery, perform the following procedure.
- Manually stop the CTDB resource with the following command:
[root@z1 ~]#
pcs resource debug-stop ctdb - After you stop the resource, the system should recover the service. Check the cluster status with the
pcs statuscommand. You should see that thectdb-cloneresource has started, but you will also see actdb_monitorfailure.[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 ...To clear this error from the status, enter the following command on one of the cluster nodes:[root@z1 ~]#
pcs resource cleanup ctdb-clone
