Gluster users - Aug 2015 - Very slow ls

Hello,

If starting setup right now, you should start with current version (3.7.X)

We need more data/context as you were able to feed 150GB before having
issue.

Info:
Filesystem
network type (lan, VM...)
where is client (same lan?)
MTU
storage (raid, # of disks...)

Cordialement,

Is 3.7 stable? I have 60+ potential users and dont want to risk too
much. ;-)

Yep

1500

The bricks are all on separate servers. On each is a XFS partition on a
single HDD (together with other partitions for system etc.). All in all
there are currently seven machines involved.

I just noticed that on all servers the
/var/log/glusterfs/etc-glusterfs-glusterd.vol.log is full of messages like

readv on /var/run/a91fc43b47272ffaace2a6989e7b5e85.socket failed (Invalid
argument)
I assume this to be part of the problem?

Regards :-)
Florian
