Pinned topic mmbackup with multiple nodes

‏2013-07-16T13:01:59Z |

Hi,

1 cluster on GPFS 3.5.0.8
5 nodes (kgpfsp1, kgpfsp2, agpfsp1, agpfs2, sgpfsp1), the first 4 nodes are quorum manager and the last is a quorum/tiebreaker. the first 4 nodes have access to all nsd (except those used as tiebreaker by the last node)
4 filesystems
/gpfs/brm is the mount point for fs /dev/gpfs_root
/gpfs/brm/.office1 is the mount point for fs /dev/office1

I want to run mmbackup with 4 nodes with the following command on kgpfsp1:
/usr/lpp/mmfs/bin/mmbackup /dev/office1 -N kgpfsp1,kgpfsp2,agpfsp1,agpfsp2 -g /gpfs/brm/backup -s /gpfs/brm/backup/tmp -f

However, it seems only kgpfsp1 participate to the backup.
It has worked in the past (I believe with GPFS 3.4.0.7)

mmbackup output:
--------------------------------------------------------

--------------------------------------------------------
Tue Jul 16 08:01:26 2013 mmbackup:Scanning file system office1

Tue Jul 16 08:09:03 2013 mmbackup:Sending files to the TSM server [45744 changed, 6179 expired].

 

Is there any way to debug why the other nodes are not participating to the backup?

 

Best regards,

    Hi Yannick,

    You might want to try the -v (verbose) or -d (debug) flags of mmbackup. Besides that the man page for mmbackup also explains several useful environment variables like MMBACK_PROGRESS_CONTENT. All these could give you some additional clues as to what is going on. Also make sure each of the nodes can perform operations to the TSM server(s).

    Good luck,

    Paul.
