unable to remove brick, pleas help
Hi,
I am trying to remove a brick, from a server which is no longer part of the
gluster pool, but I keep running into errors for which I cannot find
answers on google.

Deploying libvirt with live migration
I have two physical servers: Virt1 and Virt2. I'm setting up live
migration with CentOS 5.5 between the two. I've done this by NFS
mounting /etc/libvirt and /var/lib/libvirt/images on both servers. This
is working well for me except for one thing.
I see the same list of VMs on each server (as expected), but each server
(Virt1 and Virt2) are able to start the same VM at the same time.

Gluster replicate 3 arbiter 1 in split brain. gluster cli seems unaware
Hey,
Can you give us the volume info output for this volume?
Why are you not able to get the xattrs from arbiter brick? It is the same
way as you do it on data bricks.
The changelog xattrs are named trusted.afr.virt_images-client-{1,2,3} in
the getxattr outputs you have provided.
Did you do a remove-brick and add-brick any time? Otherwise it will be
trusted.afr.virt_images-client-{0,1,2} usually.

Gluster replicate 3 arbiter 1 in split brain. gluster cli seems unaware
Here is the process for resolving split brain on replica 2:
https://access.redhat.com/documentation/en-US/Red_Hat_Storage/2.1/html/Administration_Guide/Recovering_from_File_Split-brain.html
It should be pretty much the same for replica 3, you change the xattrs with something like:
# setfattr -n trusted.afr.vol-client-0 -v 0x000000000000000100000000 /gfs/brick-b/a

Gluster replicate 3 arbiter 1 in split brain. gluster cli seems unaware
Hi Karthik,
Thanks for the info. Maybe the documentation should be updated to
explain the different AFR versions, I know I was confused.
Also, when looking at the changelogs from my three bricks before fixing:
Brick 1:
trusted.afr.virt_images-client-1=0x000002280000000000000000
trusted.afr.virt_images-client-3=0x000000000000000000000000

Gluster replicate 3 arbiter 1 in split brain. gluster cli seems unaware
Hey Henrik,
Good to know that the issue got resolved. I will try to answer some of the
questions you have.
- The time taken to heal the file depends on its size. That's why you were
seeing some delay in getting everything back to normal in the heal info
output.
- You did not hit the split-brain situation. In split-brain all the bricks
will be blaming the other bricks. But in your case the

swig_up
Tracing down some things to add in validators and I''ve run across
something that kinda bothers me...
In order to implement validators you have to override the clone method.
The directors seems to be set up to specifically handle this situation.
However, whenever C++ calls back to the object''s methods the swig_get_up
function is returning false. It seems like swig_up

Centos8: Glusterd do not start correctly when I startup or reboot all server together
The systemd glusterd.service unit modify do not resolve my problem
The solution is mount the glusterfs volume with this line into
/etc/fstab:
virt2:/gfsvol2 /virt-gfs glusterfs defaults,_netdev,noauto,x-systemd.automount,x-systemd.device-timeout=20,x-systemd.requires=glusterd.service 0 0
run
systemctl daemon-reload
and run this for mount the volume
systemctl restart virt\\x2dgfs.mount

How to diagnostic UDP discovery failed situation
Hi, experts
for example, the below case:
You can see a lot of back and forth MTU probe packets been exchanged between tinc nodes, but it’s weird that, from the debug log, one line shows "No response to MTU probes from node1”, but it indeed received a lot of MTU probe response, and finally it get the conclusion of "Packet for node1 (1.1.1.1 port 443) larger than minimum MTU”.

samba 4 dns-update issue
Hi all,
I've setup samba4 according to the samba4 wiki on centOS 5.4 in KVM.
This went without any problems. I only had to install a higher version of
bind to 9.6.x because Centos bind in repo will install version 9.3.x.
I've used the Fedora12 source rpms for this to build bind 9.6.x on Centos
5.4.
Then I configured bind according to the samba wiki

Sync data
I guys!
i have 2 servers in replicate mode, the node 1 has all data, and the
cluster 2 is empty.
I created a volume (gv0) and start it.
Now, how can I synchronize all files on the node 1 by the node 2 ?
Steps that I followed:
gluster peer probe node1
gluster volume create gv0 replica 2 node1:/data node2:/data
gluster volume gvo start
thanks!

Share Hiera configuration between 2 nodes?
Hi,
I am trying to use Hiera in puppet 3 and I have two nodes that both need
the same configuration. In this case they are two web servers which have
the same apache configuration.
Rather than creating two seperate hiera files for node1.yaml and node2.yaml
is there a way to group these by role (e.g. webserver.yaml)? I want to
avoid duplicating the configuration if possible and keep the data
