Placing a Gluster master storage domain into maintenance mode fails

Solution In Progress - Updated -


  • I fail to deactivate the master storage domain and move it to another storage domain.

  • When i put the current master storage domain into maintenance it fails and reconstructs the same storage domain.

  • Trying to put the master storage domain into maintenance mode fails.

  • The vdsm logs on the SPM host contain;

jsonrpc.Executor/0::ERROR::2016-07-21 05:35:39,989::sp::864::Storage.StoragePool::(masterMigrate) migration to new master failed
Traceback (most recent call last):
  File "/usr/share/vdsm/storage/", line 853, in masterMigrate
  File "/usr/share/vdsm/storage/", line 68, in tarCopy
    raise TarCopyFailed(tsrc.returncode, tdst.returncode, out, err)
TarCopyFailed: (1, 0, '', '')
  • Further debugging revealed that the tar` command was reporting file changed as we read it for files associated with active tasks on the SPM host.
