Gluster users - Jan 2018 - It necessary make backup the .glusterfs directory ?

Hi All,

I have two glusterfs servers and doing the backup of these is very slow, 
when it does not fail.
I have thousand and thousand and thousand files...

Apparently the directory .glusterfs has some responsibility for the 
backup failure.

Is necessary to make a backup of the .glusterfs directory?

Thanks in advance.

Not sure what kind of backup you're doing but .glusterfs contents are 
essential for things to work properly. Have you tried using 
replication/geo-replication/volume snapshot features that gluster provides?

In my experience .glusterfs is easily recoverable by going to the
brick path (if you have files there) and running stat for each object
but through mount point, something like:
cd BRICKPATH
sudo find . -path ./.glusterfs -prune -o -exec stat 'MUNTPATH/{}' \;

for example, if you need to recreate or create another volume - delete
.glusterfs and reset brick folder attr, and proceed with below trick
export brick_path=/main/brick4/geo0
sudo setfattr -x trusted.glusterfs.volume-id $brick_path
sudo setfattr -x trusted.gfid $brick_path
sudo rm -rf $brick_path/.glusterfs

files go nowhere - and they are everywhere you replicate them with Gluster

Hi Ravishankar

I make external full/incremental backup the applicattion's data. Only 
one server, not all. I not using special features the gluster.
I think if I need restore files, .glusterfs it is rebuilt when I copy 
the files in the filesystem. Is this correct?
