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

Yeah, at the moment it would certainly be my advice to other to stick with 3.2... I've just had a quick look, and can't see any docs on downgrading 3.4 to 3.2, don't suppose you're aware of any (or anyone doing this?) 

Thanks All 

Alex

Thanks for sharing. 

Btw, I do believe that GlusterFS 3.2.x is much more stable than 3.4.x in production.

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.

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

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

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
