The Lock file has to be on the Shared BRICK mounted. Make sure that GlusterFS is running. The CTDB files must be on the same Gluster Volume mounted on each server for it to work correctly.
Here’s my steps. === CTDB install [root@gls001 ~]# yum install ctdb [root@gls001 ~]# cd /etc/ctdb/ [root@gls001 ctdb]# ln -s /mnt/GlusterVolume001/ctdb/nodes . [root@gls001 ctdb]# ln -s /mnt/ GlusterVolume001/ctdb/public_addresses . [root@gls001 ctdb]# cd /etc/sysconfig/ [root@gls001 sysconfig]# rm -f ctdb [root@gls001 sysconfig]# ln -s /mnt/ GlusterVolume001/ctdb/ctdb . [root@gls001 sysconfig]# service ctdb start [root@gls001 sysconfig]# chkconfig ctdb on Thomas Holkenbrink / Systems Architect, Cloud e: [email protected] t: 425-328-1172 | c: 206-659-3677 From: [email protected] [mailto:[email protected]] On Behalf Of Sharad Shukla Sent: Thursday, April 30, 2015 9:56 AM To: Alex Crow Cc: gluster-users Subject: Re: [Gluster-users] Shared IP address Hi Alex and friends, I have installed CTDB and all related packages . I did all the required steps to configure ctdb and samba configuration, but somehow the lockfile functionality does not work. Following is the ctdb configuration: CTDB_RECOVERY_LOCK="/mnt/datavaol/lock/lockfile" CTDB_PUBLIC_ADDRESSES=/etc/ctdb/public_addresses CTDB_MANAGES_SAMBA=yes CTDB_NODES=/etc/ctdb/nodes Having the above config I was getting the error "Unable to find lockfile". So the problem was with CTDB_RECOVERY_LOCK, so I commented it. After this I again started ctdb services but now the Samba starting was a big problem.... I was getting the following error: Starting SMB services: /bin/bash: line 1: 4339 Aborted (core dumped) smbd -D Following is the smb.conf: [global] clustering = yes idmap backend = tdb2 private dir = /mnt/datavol/lock [share] comment = Gluster and CTDB based shared volume path = /mnt/datavol/share read only = no guest ok = yes I tried every possible way to start Samba daemon but failed to do so .. I would really appreciate if you can look into this configuration and suggest me some tips to make ctdb running without any errors..

I am using CentOs 6.6. The gluster volume is set up and running fine. I am manually creating the files onto the mounted volume and they are replicating.. So far looks like everything is working. Now I have configured a shared ip address for reaching the replicated volume by using the following command: gluster volume set [VOLUME] auth.allow [IP ADDRESS] This IP address is visible to me under "gluster volume info", but I am unable to ping this ip address. I am getting the message that "Host is unreachable" I need this ip address reachable so that I can connect my application which needs to use this shared ip to connect to cluster. This application is a little urgent for me. I would really appreciate your help.. Thanks Sharad Hi, That command is just setting an acl for that IP to connect to the gluster daemon. Normally you don't need to add any IP addresses as glusterfs clients will know about both servers as soon as they connect to one of them. If you're using Samba or NFS the preferred option is to use CTDB to spread a pool of virtual IP addresses over the servers.
