[Gluster-users] replace-brick failing - transport.address-family not specified

[Alex Pearson]

Hi All,
Just to assist anyone else having this issue, and so people can correct me if I'm wrong...

It would appear that replace-brick is 'horribly broken' and should not be used in Gluster 3.4.  Instead a combination of "remove-brick ... count X ... start" should be used to remove the resilience from a volume and the brick, then "add-brick ... count X" to add the new brick.

This does beg the question of why the hell a completely broken command was left in the 'stable' release of the software.  This sort of thing really hurts Glusters credibility.

Cheers

Alex

Hello,
I have what I think is a fairly basic Gluster setup, however when I try to carry out a replace-brick operation it consistently fails...

Here are the command line options:

root at osh1:~# gluster volume info media
 
Volume Name: media
Type: Replicate
Volume ID: 4c290928-ba1c-4a45-ac05-85365b4ea63a
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: osh1.apics.co.uk:/export/sdc/media
Brick2: osh2.apics.co.uk:/export/sdb/media

root at osh1:~# gluster volume replace-brick media osh1.apics.co.uk:/export/sdc/media osh1.apics.co.uk:/export/WCASJ2055681/media start
volume replace-brick: success: replace-brick started successfully

root at osh1:~# gluster volume replace-brick media osh1.apics.co.uk:/export/sdc/media osh1.apics.co.uk:/export/WCASJ2055681/media status
volume replace-brick: failed: Commit failed on localhost. Please check the log file for more details.

I've tried placing the transport.address-family option in various places, however it hasn't helped.

Any help would be very much appreciated.

Thanks in advance

Alex
