Re: question about replicate volume

[songxin <songxin_1980@xxxxxxx>]

Before step 6, there are some files(a,b,c), that are created at step 5 , in the A brick when volume type is distribute.

Should the files(a,b,c) in A brick be move to another directory before step 6?

And move back, after step 6, when the volume type is changed to replicate?

Thanks,

Xin

Hi,

Thank you for answering my question. And I have another question to ask.

If there has been some file(c, d, e) in the B node brick before step 6 as below.And the file c is diffetent with file c created in A mount poin.

Any new brick that you add to a volume has to be empty. It must not contain data or be a brick that was  a part of another volume etc.
Hope that helps,
Ravi

8.gluster volume heal gv0 info fulll                                                                                        //run on A node

After step 7, should some split-brain entries be present?

After step 8, should all files (a,b,c,d,e) will be replicate in volume gv0?

If so, how the file c be replicated when the file c is different between A brick  and B brick?
