Hi Nux,
Is only open count being shown as "0", or all stats being shown as "0"?
With regards,

Hi Shishir,
For all bricks I get:

Hi all,
we have a strange sync issue. Scenario:
- GlusterFS 3.2.5 with two nodes, N1 and N2, replicating over VLAN
- Both nodes share the /home folder, in both cases mounted on
/mnt/glusterfs/
- If I create file in N1 /mnt/glusterfs/user1/test.txt it shows up in
/home/user1/test.txt - all normal
- It also shows up on N2 in /mnt/glusterfs/user1/test.txt - but NOT
(and
this is the odd part) in N2 /home/user1/
- If I do the same starting from N2, creating a file in N2
/mnt/glusterfs/user1/test.txt it all works: the file shows up in N2
/home/user1, N1 /mnt/glusterfs/user1 and N1 /home/user1
My questions are (if they can be answered based on the info provided):
- What could have gone wrong and how to fix it?
- How do I re-sync the /home folder in N2 to match the content of
glusterfs - which is correct in the virtual FS N2 /mnt/glusterfs
It seems that N2 has lost the wires between the glusterfs db and the 'real
world' of the filesystem.
With many thanks,
Cristiano

Thanks - sorry for the delay responding. I switched it to running as
super-user and that has fixed the problem. I'll have to investigate
mount-broker in future.

I'm getting an error "ReceClient: call ?:?:? (xtime) failed on peer with
OSError". On the replication target I'm getting the same error, but with
a stack trace leading back to where it tries to set extended attributes in
the Python replication code. It appears to be trying to get the attribute
"system.glusterfs.xyz.xtime" at line 365 of
/usr/lib/glusterfs/glusterfs/python/syncdaemon/resource.py:
"Xattr.lgetxattr(path, '.'.join([cls.GX_NSPACE, uuid, 'xtime')], 8))".

Right now I am just using virsh to start the machines, I have also
tried using Virtual Machine Manager to start them.
I have enabled Gluster mounting from insecure ports, forgot to mention
that in my first email. It looks like the disk mounts as it starts to
boot but nothing can be written to the disk as it just hangs in an
infinite loop.
Thanks,

Thanks for your replies.
The vols seem to match the bricks ok.
FWIW, gfs-node01:/sda is the first brick; perhaps it is getting the lion's
share of the pointers?
The results of a log search and seem even more confusing. sdb drained
rather than sda, but an error in rebalancing shows up in sdd. I include
excerpts from scratch-rebalance, ls -l and getfattr, and bricks/sda
Does any of this suggest anything?
One failure is an apparent duplicate. This seems to refer to the relevant
brick, and the date is correct.

[LP] We will clarify that in the quick start guide. Thank you for
pointing it out. While we update the community site, please refer to
the documentation available here http://goo.gl/bQFI8o for a usage guide.
As for the tool, the format is:
gluster-swift-gen-buildes [VOLUME] [VOLUME...]
Where VOLUME is the name of the GlusterFS volume to use for object
storage. For example
if the following two GlusterFS volumes, volume1 and volume2, need to be
accessed over Swift,
then you can type the following:
# gluster-swift-gen-builders volume1 volume2
For more information please read: http://goo.gl/gd8LkW
Let us know if you have any more questions or comments.

Try 'chmod qemu.qemu image_on_gluster.qcow2'. This along with the
'option rpc-auth-allow-insecure on' and 'gluster volume set <volname>
server.allow-insecure on' should make libvirt+qemu+libgfapi work.

Hi Nux,
I am trying to see if the issue of "0" open fd is based on the work-load,
or a bug.
Could you check top command output of "read/write" operation too?
With regards,
Shishir

Hi Vijay
I used the code in

Date: Tue Sep 17 16:45:03 2013 -0700
Revert "cluster/distribute: Rebalance should also verify free inodes"
This reverts commit 215fea41a96479312a5ab8783c13b30ab9fe00fa
Realized soon after merging, ?.
which include the patch you mentioned last time improve read perf, written
by Anand.
but the read perf was still slow:
write: 500MB/s
read: 77MB/s
while via fuse :
write 800MB/s
read 600MB/s
any advises?
Thank you.

Hi Anand,
I use 2 gluster server , this is my volume info:

Message-ID:
<AC3305F9C186F849B835A3E6D3C9BEFEAFA70E at KWTPRMBX001.mha.local>

HI,
I have 2 gluster nodes (GFS01/GFS02) each with a single brick (B01/B01). I
have created a simple replica volume with these bricks.
Bricks : GFS01/B01 and GFS02/B01.
Volume: TestVol
I have 2 clients (C01/C02) which will mount this "testvol" for
simultaneous read/write. The 2 clients run the same application which is
load-balanced, so user request are end to both the client servers which
reads/writes data to both the same volume.
Mounting the volume on C1 : mount -t glusterfs -o
backupvolfile-server=GFS02 GFS01:/testvol /data
Mounting the volume on C2 : mount -t glusterfs -o
backupvolfile-server=GFS01 GFS02:/testvol /data
Is this the appropriate way to be followed.?
At times, I notice that when I write data through C1-mount point the data
is written only to GFS01/B01 and if data is written through C2-mount point
the data is written only to GFS02/B01.
Please advise. !!
Thanks & Regards,
Bobby Jacob

Hello,
this ist he behavior as if you write directly into the glusterd

Betreff: [Gluster-users] Mounting same replica-volume on multiple clients.
????
HI,
I have 2 gluster nodes (GFS01/GFS02) each with a single brick (B01/B01). I
have created a simple replica volume with these bricks.
Bricks ?? : GFS01/B01 and GFS02/B01.
Volume: TestVol
I have 2 clients (C01/C02) which will mount this ?testvol? for
simultaneous
read/write. The 2 clients run the same application which is load-balanced,
so user request are end to both the client servers which reads/writes data
to both the same volume.
Mounting the volume on C1?????? :?????????????? mount ?t glusterfs ?o
backupvolfile-server=GFS02 GFS01:/testvol /data
Mounting the volume on C2?????? :?????????????? mount ?t glusterfs ?o
backupvolfile-server=GFS01 GFS02:/testvol /data
Is this the appropriate way to be followed.?
At times, I notice that when I write data through C1-mount point the data
is
written only to GFS01/B01 and if data is written through C2-mount point
the
data is written only to GFS02/B01.
Please advise. !!
Thanks & Regards,
Bobby Jacob

I have already used "kernel oplocks = no" in the smb.conf, next is my
original smb.conf file global settings:
[global]
workgroup = MYGROUP
server string = DCS Samba Server
log file = /var/log/samba/log.vfs
max log size = 500000
aio read size = 262144
aio write size = 262144
aio write behind = true
security = user
passdb backend = tdbsam
load printers = yes
cups options = raw
read raw = yes
write raw = yes
max xmit = 262144
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=262144
SO_SNDBUF=262144
# max protocol = SMB2
kernel oplocks = no
stat cache = no

Exactly. !! BUT I am writing through the volume mount-point from the
clients. !! NOT directly into the bricks. !!
I'm using GlusterFS 3.3.2 with Centos6.4 . !

HI,
I have 2 gluster nodes (GFS01/GFS02) each with a single brick (B01/B01). I
have created a simple replica volume with these bricks.
Bricks ?? : GFS01/B01 and GFS02/B01.
Volume: TestVol
I have 2 clients (C01/C02) which will mount this "testvol" for
simultaneous read/write. The 2 clients run the same application which is
load-balanced, so user request are end to both the client servers which
reads/writes data to both the same volume.
Mounting the volume on C1?????? :?????????????? mount -t glusterfs -o
backupvolfile-server=GFS02 GFS01:/testvol /data Mounting the volume on
C2?????? :?????????????? mount -t glusterfs -o
backupvolfile-server=GFS01 GFS02:/testvol /data
Is this the appropriate way to be followed.?
At times, I notice that when I write data through C1-mount point the data
is written only to GFS01/B01 and if data is written through C2-mount point
the data is written only to GFS02/B01.
Please advise. !!
Thanks & Regards,
Bobby Jacob

Can you get the volume profile dumps for both the runs and compare them?

What about
gluster volume info on both nodes!?
Ex.:
Volume Name: sambacluster
Type: Replicate
Volume ID: 4fd0da03-8579-47cc-926b-d7577dac56cf
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: s4master:/raid5hs/glusterfs/samba
Brick2: s4slave:/raid5hs/glusterfs/samba
Options Reconfigured:
network.ping-timeout: 5
performance.quick-read: on
What are telling you your log files?

Exactly. !! BUT I am writing through the volume mount-point from the
clients. !! NOT directly into the bricks. !!
I'm using GlusterFS 3.3.2 with Centos6.4 . !

Hello,
this ist he behavior as if you write directly into the glusterd

Tested with glusterfs-3.4.1qa2-1.el6.x86_64 issue with ACL is still there,
unless one applies patch from http://review.gluster.org/#/c/5693/ which
shoots through the caches and takes ACLs from server or sets
entry-timeout=0 it returns wrong values. This is probably because ACL mask
being applied incorrectly in posix_acl_inherit_mode, but I'm no C expert
to
say so :(

Shishir,
Those commands only output the bricks and nothing more:
[root at 2216 ~]# gluster volume top xenvms read nfs
NFS Server : localhost
NFS Server : 1726.stocare.domeniu.net
NFS Server : 1613.stocare.domeniu.net
NFS Server : 1631.stocare.domeniu.net
[root at 2216 ~]# gluster volume top xenvms write nfs
NFS Server : localhost
NFS Server : 1631.stocare.domeniu.net
NFS Server : 1613.stocare.domeniu.net
NFS Server : 1726.stocare.domeniu.net
Same without "nfs".

Encryption

Hi Gluster Users,
I'm looking for some advice or best practice recommendations when it
comes to designing secure glusterFS environments. I'm talking about the
basic design principles that a user should consider irrespective of the
content that will be stored. I realise security isn't a destination but
a journey but I'd appreciate any advice you may have and it goes without
saying that if the content is that important it should be separated.
What is the current advise on configuring secure glusterFS environments
or the trade-offs to consider?
Should everything from bricks to storage nodes and the storage data
network be separated into different glusterFS's or can I share storage
nodes across different clients without fear of crossed wires or a rogue
client being able to list the other mount points of other clients or
worse access their data?
My mindset would be to try and compare it to a SAN (but I'm not a SAN
guy either) where disk storage is pooled and provisioned as LUN's and
the LUN's are presented to certain HBA's . The SAN can be configured so
that only particular HBA's can access a LUN so even if the client is
compromised the SAN doesn't allow it to access other LUN's
Finally also on the topic of security how would people suggest handling
encryption of client data and working with a storage server hosting
different encrypted data

Dragon,
Could you attach brick log files, client log file(s) and output of the
following
commands,
gluster volume info VOLNAME
gluster volume status VOLNAME
Could you attach the "etc-glusterfs.." log as well?
thanks,
krish
