Hi,
Do not use sharding and stripe together in the same volume because
a) It is not recommended and there is no point in using both.
Using sharding alone on your volume should work fine.
b) Nobody tested it.
c) Like Niels said, stripe feature is virtually deprecated.
I would suggest that you create an nx3 volume where n is the
number of distribute subvols you prefer, enable group virt
options on it, and enable sharding on it,
set the shard-block-size that you feel appropriate and then just
start off with VM image creation etc.
If you run into any issues even after you do this, let us know
and we'll help you out.

Thanks Krutika,
I have deleted the volume and created a new one.
I found that it may be an issue with the NFS itself, i have
created a new striped volume and enabled sharding and mounted
it via glusterfs and it worked just fine, if i mount it with
nfs it will fail and gives me the same errors.

Hi,
So could you share the xattrs associated with the file at
<BRICK_PATH>/.glusterfs/c3/e8/c3e88cc1-7e0a-4d46-9685-2d12131a5e1c
Here's what you need to execute:
# getfattr -d -m . -e hex
/mnt/b1/v/.glusterfs/c3/e8/c3e88cc1-7e0a-4d46-9685-2d12131a5e1c

# getfattr -d -m . -e hex
/mnt/b2/v/.glusterfs/c3/e8/c3e88cc1-7e0a-4d46-9685-2d12131a5e1c
on the second.
Also, it is normally advised to use a replica 3 volume as
opposed to replica 2 volume to guard against split-brains.

Niels
Couple of things to note before you do that:
1. Most of the bug fixes in sharding have gone into 3.7.8. So it is
advised
that you use 3.7.8 or above.
2. When you enable sharding on a volume, already existing files in
the
volume do not get sharded. Only the files that are newly created
from the
time sharding is enabled will.
If you do want to shard the existing files, then you would
need to cp
them to a temp name within the volume, and then rename them back to
the
original file name.

Is it possible the LSI has write-cache enabled?
Why is that relevant? Even the backing filesystem has no idea if
there is
a RAID or write cache or whatever. There are blocks and sync(), end
of
story.
If you lose power and screw up your recovery OR do funky stuff with
SAS
multipathing that might be an issue with a controller cache. AFAIK
thats
not what we are talking about.
I'm afraid but unless the OP has some logs from the server, a
reproducible testcase or a backtrace from client or server this
isn't
getting us anywhere.

I'd look through mail archives for a topic "Shard in Production" I

Is their a raid controller perhaps doing any caching?

Since they aren't in use yet have you tested making just mirrored
bricks
using different pairings of servers two at a time to see if problem
follows
certain machine or network ports?
