Testing sharding on tiered volume
Hi,
I'm looking to use sharding on tiered volume. This is very attractive
feature that could benefit tiered volume to let it handle larger files
without hitting the "out of (hot)space problem".
I decided to set test configuration on GlusterFS 3.12.3 when tiered volume
has 2TB cold and 1GB hot segments. Shard size is set to be 16MB.
For testing 100GB files are used. It seems writes

yes, i've opened a bug asking developers to block removal of sharding
when volume has data on it or to write a huge warning message
saying that data loss will happen

Reconstructing files from shards
Hello,
So I have a volume on a gluster install (3.12.5) on which sharding was enabled at some point recently. (Don't know how it happened, it may have been an accidental run of an old script.) So it has been happily sharding behind our backs and it shouldn't have.
I'd like to turn sharding off and reverse the files back to normal. Some of these are sparse files, so I need to account

Reconstructing files from shards
From some old May 2017 email. I asked the following:
"From the docs, I see you can identify the shards by the GFID
# getfattr -d -m. -e hex/path_to_file/
# ls /bricks/*/.shard -lh | grep /GFID
Is there a gluster tool/script that will recreate the file?
or can you just sort them sort them properly and then simply cat/copy+
them back together?
cat shardGFID.1 .. shardGFID.X > thefile

Hiera data in mongodb backend: schema question
I''m thinking about creating a web service to provide hiera data. The backend I''m looking into is Mongodb. Front end would implement hiera-http. Does anyone have any recommendations on the mongodb schema and how it would look. I checked out some articles online for hierarchical data in mongodb but not sure how that would map to a hiera backend.

Reconstructing files from shards
The short answer is - no there exists no script currently that can piece
the shards together into a single file.
Long answer:
IMO the safest way to convert from sharded to a single file _is_ by copying
the data out into a new volume at the moment.
Picking up the files from the individual bricks directly and joining them,
although fast, is a strict no-no for many reasons - for example, when you

Very slow performance on Sharded GlusterFS
Just noticed that the way you have configured your brick order during
volume-create makes both replicas of every set reside on the same machine.
That apart, do you see any difference if you change shard-block-size to
512MB? Could you try that?
If it doesn't help, could you share the volume-profile output for both the
tests (separate)?
Here's what you do:
