Command failed: Could not add TB

Question

Hello, I try to deploy 3 node cluster of ScaleIO, upload and install packages phases goes well, but on configure phase I receive error and don't have a clue how to fix this: Command failed: Could not add TB 10.10.50.138 on 10.10.50.136,10.10.50.135 due to: Communication error {   'mdmIPs': [     '10.10.50.136',     '10.10.50.135'   ],   'mdmPassword': 'xxxxx',   'tb': {     'node': {       'ostype': 'linux',       'nodeName': null,       'nodeIPs': [         '10.10.50.138'       ],       'domain': null,       'userName': 'root',       'password': 'xxxxx',       'liaPassword': 'xxxxx'     },     'nodeInfo': {       'diskDevices': [         {           'diskName': '/dev/xvdb'         },         {           'diskName': '/dev/xvda'         },         {           'diskName': '/dev/sr0'         },         {           'diskName': '/dev/xvda1'         }       ],       'installedComponents': [],       'osType': 'linux',       'linuxFlavour': 'rhel7',       'pythonInstalled': true,       'timestamp': '2016-01-22T12:39:21.330Z'     },     'tbIPs': [       '10.10.50.138'     ]   },   'commandState': 'failed',   'startTime': '2016-01-22T12:53:11.069Z',   'message': 'Command failed: Could not add TB 10.10.50.138 on 10.10.50.136,10.10.50.135 due to: Communication error',   'result': null,   'followingCommand': 'SwitchToClusterModeCommand[working on= (MDM) [10.10.50.136, 10.10.50.135]]',   'allowedState': 'configure',   'archived': false,   'commandName': '.AddTbCommand' } Maybe anyone have idea how to solve this? In all 3 nodes firewall is disabled. Best regards, Martins

When specifying SDS device path on a Linux node in CSV file, the user should use the path according to what's written in '/proc/partitions' (and not according to 'fdisk -l')

example:

fdisk output: /dev/mapper/samah-lv1, /dev/sdb

/proc/partitions value : dm-3, sdb

value to write in CSV file: /dev/dm-3, /dev/sdb

Thanks,

Tomer
