Hi,
I'm slowly finding my way around glusterfs and getting a little more
comfortable with the concepts of glusterfs itself.
I have a 2 node baremetal server with a 1.5 TB volume replicating and it seems
pretty damn cool.
I have now exported with samba as well. I can connect with samba to the
Just as how you can't ask xfs or ext4 how many files it has, you can't
ask Gluster the same thing. It doesn't know. It crawls the tree, looks
at the hash of the filename, and determines if it should reside on a
different brick.
To guess how much remains, look at how many are complete out of
I am using GlusterFS to make my storage between several servers can be
replicated with fault tolerance. And I am doing the similar way as

I meant to ask if you are using the same underlying filesystem and
parameters for A/B comparisons. It isn't clear what A and B are in your
comparison. You said that your performance is different with and without
gluster even if you access bricks directly. That bit is puzzling. Adding a
brick to
Hi, Cong!
Well, there is not much to advice from my experience. GlusterFS is FS type
storage, while iscsi is blockdevice. You can't export gluster bricks as
iscsi targets directrly. At least at this moment. Who knows, mby devs will
surprise us some way in this direction :) Mby HA-LVM is your pick
I've got a 4-node distributed-replicated cluster running 3.5.2. I just
added 4TB (2TB to the distribute pair and 2TB to the replicate pair) and
then started a rebalance as I believe the rebalance needed to be initiated

Hi there,
I have a split-brain situation on one of my volumes. The part that I'm not
clear on is that it would appear to be on the root of the volume.

Okay, I wasn't reading carefully... Try this:
dd if=/dev/zero of=disk3 count=1 bs=1 skip=50G
That will give you a 50GB thin-provisioned file for iSCSI.

Try adding skip=2G (I think) to your dd command and change the bs and count
both to 1. This will essentially thin-provision your iSCSI volume file.
I use this method to make iSCSI volumes that live on gluster.

Hi,
If you are connected to a node via Samba and if that node goes down, you will
have to manually connect to the other Samba node,
unless Samba nodes are clustered and you have a HA solution on top of Samba.
CTDB could be one of your options, it provides both clustering and IP failover

Hi All,
Last problem I hope.

Hi and thanks,
Well, I definitely don't want to ruin my change log (the extended attributes),

I'll have to think of a new way to integrate glusterfs in our use case.
Thanks for confirming my suspicion.

Specifically, you'll want to look at the cluster.read-hash-mode option,
