i'm getting this error in CTDB log: ERROR: samba tcp port 445, is not responding it's strange because windows (xp & 7) workstation can connect to both nodes on my cluster (active/active configuration using drbd and gfs2). i didn't noticed this error before and i can not recall i have changed anything to make this happened. first it shows up on one node and later same day on other. i forced iptables service to stop, but it didn't help. samba is actually listening on port 445 (on both nodes): [root@smb1 ~]# netstat -tulpn | egrep "samba|smbd|nmbd|winbind" tcp 0 0 0.0.0.0:139 0.0.0.0:* LISTEN 2270/smbd tcp 0 0 0.0.0.0:445 0.0.0.0:* LISTEN 2270/smbd tcp 0 0 :::139 :::* LISTEN 2270/smbd tcp 0 0 :::445 :::* LISTEN 2270/smbd [root@smb1 ~]# service ctdb status Checking for ctdbd service: Number of nodes:2 pnn:0 192.168.1.131 UNHEALTHY (THIS NODE) pnn:1 192.168.1.130 UNHEALTHY Generation:394048708 Size:2 hash:0 lmaster:0 hash:1 lmaster:1 Recovery mode:NORMAL (0) Recovery master:1 [root@smb1 ~]# smbd -V Version 4.0.0rc4 [root@smb1 ~]# cat /etc/sysconfig/ctdb CTDB_RECOVERY_LOCK="/clusterdata/ctdb.lock" CTDB_PUBLIC_INTERFACE=eth0 CTDB_PUBLIC_ADDRESSES=/etc/ctdb/public_addresses CTDB_MANAGES_SAMBA=yes ulimit -n 10000 CTDB_NODES=/etc/ctdb/nodes CTDB_LOGFILE=/var/log/log.ctdb CTDB_DEBUGLEVEL=2 CTDB_PUBLIC_NETWORK="192.168.1.0/24" CTDB_PUBLIC_GATEWAY="192.168.1.1" [root@smb1 ~]# ctdb scriptstatus 12 scripts were executed last monitor cycle 00.ctdb Status:OK Duration:0.008 Wed Jan 22 20:51:29 2014 01.reclock Status:OK Duration:0.019 Wed Jan 22 20:51:29 2014 10.interface Status:OK Duration:0.028 Wed Jan 22 20:51:29 2014 11.routing Status:OK Duration:0.007 Wed Jan 22 20:51:29 2014 11.natgw Status:OK Duration:0.007 Wed Jan 22 20:51:29 2014 11.route Status:OK Duration:0.007 Wed Jan 22 20:51:29 2014 13.per_ip_routing Status:OK Duration:0.007 Wed Jan 22 20:51:29 2014 20.multipathd Status:DISABLED 31.clamd Status:DISABLED 40.vsftpd Status:OK Duration:0.008 Wed Jan 22 20:51:29 2014 41.httpd Status:OK Duration:0.008 Wed Jan 22 20:51:29 2014 50.samba Status:ERROR Duration:0.040 Wed Jan 22 20:51:29 2014 OUTPUT:ERROR: samba tcp port 445, is not responding There were nothing on google, I'm desperate...
