Hi Patrick,
This would be amazing, if possible.
Checking /gluster_bricks/data/data on the host where I've removed (but not replaced)
the bricks, I see a single directory.
When I go into that directory, I see two directories:
dom_md
images
If I go into the images directory, I think I see the hash folders that you're
referring to, and inside each of those, I see the 3 files you referenced.
Unfortunately, those files clearly don't have all of the data.
The parent folder for all of the hash folders is only 687M.
[root@cha1-storage data]# du -skh *
687M 31366488-d845-445b-b371-e059bf71f34f
And the "iso" files are small. The one I'm looking at now is only 19M.
It appears that most of the actual data is located in
/gluster_bricks/data/data/.glusterfs, and all of those folders are totally random,
incomprehensible directories that I'm not sure how to understand.
Perhaps you were on an older version of Gluster, and the actual data hierarchy is
different?
I don't know. But I do see the 3 files you referenced, so that's a start, even if
they are nowhere near the correct size.

Greetings, I once wondered how data is stored between replicated
bricks. Specifically, how disks are stored on the storage domain in Gluster. I checked a
mounted brick via the standard path (path may be different) /gluster/data/data and saw
many directories there. Maybe the hierarchy is different, can't check now. But in the
end I got a list of directories. Each directory name is a disk image hash. After going to
a directory such as /HASH there were 3 files. The first is a disk in raw/iso/qcow2 format
(but the file has no extension, I looked at the size) the other two files are the
configuration and metadata. I downloaded the disk image file (.iso) to my computer via the
curl command and service
www.station307.com (no ads). And I got the original .iso which
uploaded to the storage domain through the hosted engine interface. Maybe this way you can
download the disk image to your computer and then load it via the GUI and connect it to a
virtual machine. Good luck!
