Hi everyone,

We've been using 3.3.2 for a while, and recently started to migrate to 
3.4.2. We run on platform CentOS 6.5 for 3.4.2 (while 3.3.2 were installed 
on CentOS 6.4)

Recently, we've have a very scary condition happen and we do not know 
exactly the cause of it.

We have a 3 nodes cluster with a replication factor of 3. Each node has 
one brick, which is made out of one RAID0 volume, comprised of multiple 
SSDs.

Following some read/write errors, nodes 2 and 3 have completely locked. 
Nothing could be done physically (nothing on the screen, nothing by SSH), 
physical power cycle had to be done. Node 1 was still accessible, but its 
fuse client rejected most if not all reads and writes.

Has anyone experienced something similar?

Before the system freeze, the last thing the kernel seemed to be doing is 
killing HTTPD threads (INFO: task httpd:7910 blocked for more than 120 
seconds.)  End-users talk to Apache in order to read/write from the 
Gluster volume, so it seems a simple case of "something wrong" with 
gluster which locks read/writes, and eventually the kernel kills them.

At this point, we're unsure where to look. Nothing very specific can be 
found in the logs, but perhaps if someone has pointers of what to look 
for, that could give us a new search track.

Thanks

Laurent Chouinard

Hi Paul,

Could you keep the list updated? That bug has been marked private, so
I can't see it.

Hi Adam,

This is rather odd - the Redhat specific clone of the bug we filed is 
now marked private, even if I log in with my RH bugtracker account. 
However, the original bug is still accessible:

https://bugzilla.redhat.com/show_bug.cgi?id=1057645

There's not been any progress as far as I know. We are using the 
workaround (which stops libvirt/qemu from doing the chown) in 
production. With the release of Ubuntu 14.04 LTS, I hope to be able to 
use libgfapi on our setup.

Perhaps the fact that the RedHat specific bug is now private might mean 
that they're actually doing something with it, but I wouldn't know.

Regards, Paul Boven.

If the kernel was killing things, check that it wasn't the OOM killer.
If so, you might want to ensure you've got swap, enough memory, check
if anything is leaking, and finally if you have memory management
issues between services, cgroups might be the thing to use to control
this.

I've seen issues with GlusterFS and rsync.  They were mostly ameliorated 
by
adding --inplace to my rsync arguments.

Subject: [Gluster-users] upgrading from gluster-3.2.6 to gluster-3.4.2
Message-ID: <5303B9CB.7000800 at che.ufl.edu>
Content-Type: text/plain; charset="iso-8859-1"; Format="flowed"

I am attempting to upgrade my GlusterFS from 3.2.6 to 3.4.2 using the 
instructions posted at 
http://vbellur.wordpress.com/2012/05/31/upgrading-to-glusterfs-3-3. 
These guidelines are for an upgrade to 3.3 but it is stated at 
http://vbellur.wordpress.com/2013/07/15/upgrading-to-glusterfs-3-4 that 
they can also be used to upgrade to 3.4.0. So I was hoping that they 
would also work with an upgrade to 3.4.2.

I'm running CentOS 5 and installed the following rpms on the gluster 
servers:

glusterfs-libs-3.4.2-1.el5.x86_64.rpm
glusterfs-3.4.2-1.el5.x86_64.rpm
glusterfs-fuse-3.4.2-1.el5.x86_64.rpm
glusterfs-cli-3.4.2-1.el5.x86_64.rpm
glusterfs-server-3.4.2-1.el5.x86_64.rpm
glusterfs-rdma-3.4.2-1.el5.x86_64.rpm
glusterfs-geo-replication-3.4.2-1.el5.x86_64.rpm

According to the installation guidelines, installation from rpms should 
automatically copy the files from /etc/glusterd to /var/lib/glusterd. 
This didn't happen for me -- the directory /var/lib/glusterd contained 
only empty subdirectories. But the content of /etc/glusterd directory 
has moved to /etc/glusterd/glusterd.

So, I decided to manually copy files from /etc/glusterd/glusterd to 
/var/lib/glusterd and follow step 5 of the installation guidelines 
(which was supposed to be skipped when installing from rpms):

glusterd --xlator-option *.upgrade=on -N

This didn't work (error message: glusterd: No match)

Then I triedspecifying explicitly the name of my volume:

glusterd --xlator-option <volume>.upgrade=on -N

This lead to the following messages in file 
etc-glusterfs-glusterd.vol.log:

[2014-02-18 17:22:27.146449] I [glusterd.c:961:init] 0-management: Using

...
and so on for all other bricks.

After that, files nfs.log, glustershd.log, and 
etc-glusterfs-glusterd.vol.log get filled with a large number of warning 
messages and nothing else seems to happen. The following messages appear 
to be relevant:

- Files nfs.log, glustershd.log:

2014-02-18 15:58:01.889847] W [rdma.c:1079:gf_rdma_cm_event_handler]

(the name of my volume is data-volume and its transport type is RDMA)

- File etc-glusterfs-glusterd.vol.log

[2014-02-18 17:22:33.322565] W [socket.c:514:__socket_rwv] 0-management: 
readv failed (No data available)

Also, for some reason the time stamps in the log files are incorrect.

Any suggestions for fixing this would be greatly appreciated.

Thanks,

Dmitry

Hi all,

I am getting a problem and can't understand why, I have created a cluster
with gluster following the most simple way as explaind in QuickStart on 
the
glustger.org.

I have created 3 VM in KVM.

2 To host gluster server with one disk image with 1tb.

1 To host gluster client to mounting my volume.

I'm using Debian 7 and used apt-get to install Gluster 3.2.7, Server and
Client.

After all finished I could to mount as glusterfs with no problem "mount -t
glusterfs /mnt/cloudbackup_data/ vm-gluster-cloudbackup1:/vol1" but I 
can't
to work on the mounted directory, if I perform a "ls -lh" it's running
forver, and I can't do any other operation and VM is blocked.

If I try to mount as NFS  "mount -t nfs vm-gluster-cloudbackup2:/vol1
/mnt/cloudbackup_data/ "I get a "Time out" I'm not so much expert in
gluster, but I can't see any reason for this problem, someone know
something like that?

Regards,

The Log of that particular volume says:

When I try to access the folder I get.

This is the volume info:

Nothing very obvious from these logs.

Can you share relevant portions of the client log file? Usually the name 
of the mount point would be a part of the client log file.

Hi Kaushal,

Thanks for the input.  I gave it a go and it produced identical results. I 
was, however, pointed towards an article that's led me to a solution, 
linked below.  As I understand it, by assigning each node an elastic IP, 
you cement the public DNS (now containing the elasticIP), preventing AWS 
from changing it during reboot.  Querying the public DNS from inside EC2 
returns the private IP addresses, while a query from outside EC2 returns 
the elastic IP.  Gluster seems happy with this, so I am too.

Regards,
Jon

Peer status having node1's elastic ip suggests that you probed the
other peers from node1. This would mean that the other peers don't
know of node1's hostname. Even though you've edited the hosts file on
the peers, a reverse resolution on node1s ip wouldn't return the
hostnames you've set. Gluster uses reverse resolution to match
hostnames when it doesn't have a straight match in the peer list.

To recover from this. just probe node1 from another peer. Do '#
gluster peer probe node1.ec2' from another peer. This will update
gluster's peerlist to contain the name node1.ec2. After this other
operations will continue successfully.

Hi Paul, and all

Well I hope that too, but I'm not sure if that will happen (soon).
I , recompiled qemu as described here:

http://www.gluster.org/community/documentation/index.php/Building_QEMU_with_gfapi_for_Debian_based_systems


with little luck since finally the ipxe-qemu component (which I need/want) 

and I didn't had the time to dig deeper into that.

https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1224517

still says "won't fix it" :-(

Josh Boon (hi Josh) suggested to create a PPA for an ubuntu qemu with 
gfapi support 
which might be a temporary solution?
But from my "happy end - user" perspective (as a "non-dev-but-op") 
that looks like a lot of parallel extra work
on maintaining that "fork"in the long run.
I hope the gluster devels either can get it into debian(and/or ubuntu) 
or even qemu (as a default option?) directly

I've yet to crack into 14.04 and see what that beast looks like as we 
don't have it in use here yet. I'll add that to my todo list. I can be 
bribed if someone needs it sooner :) 

As a separate task, I'll look into the ipxe problem. I remember it was 
file conflict between the packages so I may have to do some hacks in the 
debian build rules for one of the packages. 

The PPA is an option but yes maintenance would be ongoing and best effort 
as that's all I can afford currently.

I'm still not convinced that the file ownership itself is the root cause 
of 
this issue, it could well be just a symptom. Libvirt/qemu is perfectly 
happy 
to start a VM when its image file is owned root:root, and change ownership 

to libvirt-qemu:kvm. So I see no reason why it couldn't do the same during 
a 
live migration. 

In my opinion the real issue is the failure at the fuse level, that makes 
file access to the image on the destination impossible, even for root.

Hi Paul & all 
I'm really keen on getting this solved, 
right now it's a nasty show stopper. 
I could try different gluster versions,

wouldn't want to start compiling 
(although.... does a config option have changed on package build?) 
you reported that 3.4.0 on ubuntu 13.04 was working, right? 
code diff, config options for package build. 
Another approach: can anyone verify or falsify 
https://bugzilla.redhat.com/show_bug.cgi?id=1057645 
on another distro than ubuntu/debian? 
thinking of it... could it be an apparmor interference? 
I had fun with apparmor and mysql on ubuntu 12.04 once... 
will have a look at that tomorrow. 
As mentioned before, a straight drbd/ocfs2 works (with only 1/4 speed 
and the pain of maintenance) so AFAIK I have to blame the ownership change 

on gluster, not on an issue with my general setup....

Is there a proper method to recover from heal-failed entries?

rep1 is a 2 brick, quorum enabled volume used for virt storage for Ovirt,

Seeing as the hosts are both in quorum I was surprised to see this, but
these id's have been repeating in my logs.

Hi,
Does anyone have any ideas on the above?

Thanks.

You need to check the log files for obvious problems. On the servers
these should be in /var/log/glusterfs/ and you can turn on logging for
the fuse client like this:

# mount -olog-level=debug,log-file=/var/log/glusterfs/glusterfs.log  -t
glusterfs ....

Hi Bernhard,

I am making a server for store some old data via FTP, so I have a  two
bricks with 1tb each one, in a volume replica 2.

#First Node
root at vm-gluster-cloudbackup1:~# gluster volume info

Volume Name: vol1
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: vm-gluster-cloudbackup1:/mnt/data1/vol1
Brick2: vm-gluster-cloudbackup2:/mnt/data1/vol1

#Second node
root at vm-gluster-cloudbackup2:~# gluster volume info

Volume Name: vol1
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: vm-gluster-cloudbackup1:/mnt/data1/vol1
Brick2: vm-gluster-cloudbackup2:/mnt/data1/vol1

The volumes are started normaly with no problem, I am trying to get some
thing on the log files, I know that speed may be slow, but it's not a
problem to me at this moment.
