Hi,
I'm trying to install and use GlusterFS on a VPS.
I succeed to install and run it on the physical host.
I install fuse without kernel support like tis tuto http://wiki.openvz.org/FUSE
In the other side fuse is correctly working on my physical host.
GlusterFS detect my fuse install and can compile and install.

My problem is when i'm trying to run the glusterFS server deamon, it give some strange errors Confused

2009-02-24 02:25:45 C [posix.c:3604:init] brick: Extended attribute not supported, exiting
2009-02-24 02:25:45 E [xlator.c:563:xlator_init_rec] xlator: initialization of volume 'brick' failed, review your volfile again
2009-02-24 02:25:45 E [glusterfsd.c:465:_xlator_graph_init] glusterfs: initializing translator failed
2009-02-24 02:25:45 E [glusterfsd.c:1096:main] glusterfs: translator initialization failed.  exiting

I used the same attributes to install on my physical host and it's works very well.
Somebody has ever succeed to install GlusterFS on a VPS ? Rolling Eyes

Seems that indeed extended attributes are not supported inside VE but I think they are also not supported on the HN i.e. partition that is mounted to /vz. Could you possibly check this assumption?

tune2fs -l /dev/*

Filesystem features should contain ext_attr record.

The /vz directory is on the same partition than my system (it's an integration server).
My partition is /dev/sda1 and I can run glusterFSd on my HN.

Hello,

ok then are you able to strace that program?
http://wiki.openvz.org/Stracing_a_program

It would be useful to know how they're checking extended attribute support.

According to your first message glusterfsd should write error messages but attached strace output doesn't contain anything related to writing messages.

Could you please clarify how did you issue the "strace" command?

Could you please try "strace -fF -o out.txt ...".

Anyway, could you also try
"vzctl set $VEID --capability sys_admin:on"?

This is the arguments I used with strace:

strace -o gluster.out -ff glusterfsd -f glusterfs-srv.vol

I just did it again, and I have the same output file (I just renamed it).

This is the associated glusterFS log:

EDIT :

IT'S WORKS !!

The last command

vzctl set $VEID --capability sys_admin:on

What do this command ?

Hi

I had the same problems and managed glusterfsd to work now. Thanks a lot!

But, I now try to mount the device inside a container

glusterfs --debug -f /etc/glusterfs/glusterfs.vol /storage

and get the following error(s):

fuse: failed to open /dev/fuse: Permission denied
[2009-06-20 18:36:29] D [fuse-bridge.c:2747:init] glusterfs-fuse: fuse_mount() failed with error Permission denied on mount point /storage

ls -al /dev/fuse is

crw-rw-rw- 1 root fuse 10, 229 20. Jun 16:35 /dev/fuse

and ls -al /storage is

drwxr-xr-x   2 root root 4096 20. Jun 17:14 storage

the kernel of that HN has fuse loaded... a uname is

2.6.18-14-fza-amd64 #1 SMP Mon Jan 5 17:36:46 UTC 2009 x86_64 GNU/Linux

I'll attach the whole debug output.

Did you get the mount to work? How?
Any suggestions?

Thanks in advance.
Marcus

Hi again,

found the solution on my own (http://wiki.openvz.org/FUSE) Rolling Eyes

I just needed to tune my container, by berforming the following in my HN:

# vzctl set $VEID --devices c:10:229:rw --save
# vzctl exec $VEID mknod /dev/fuse c 10 229
