[Gluster-users] CIFS options - anyone done A-B comparisons on various setups?

[Gunnar]

The problem was not the open file limit. If I locally mount on a brick a 
nfs share and use it
with Samba it is not stable. I had a crash after copying 800,000 files, 
I tried a few
times with no lock, it always crashed.

The most annoying thing is that I didn't find anything in the logs, 
finally I found this article:
http://community.gluster.org/a/nfs-performance-with-fuse-client-redundancy/

After reading it I have setup a new machine, mounted the nfs share:
mount -o vers=3,nolock -t nfs gluster01.mydomain.local:/gv01 /mnt/nfsgv01
Installed Samba and set the path in smb.conf to path = /mnt/nfsgv01

As well I increased:
gluster volume set gv01 performance.write-behind-window-size 16mb

Now I'm able to copy around 2,4 million files without any problem, it is 
a bit slower
than the first approach but still ok.

I hope that it will stay stable, I will store a few million files more 
on it and see what will
happen.
