Hi,
I have a block device at /dev/blkdev. Does Gluster have some kind of
function to mount it on this block device?
Kind regards

'm trying to integrate Gluster in a
microkernel OS, to which FUSE has been ported. But to be able to use FUSE
some changes have to made in calling the fuse_main.
Kind regards

trying to look for information but the only one I've found is to
manually mount gluster in the nova node and use it via FUSE.
Can anyone provide information how to setup this environtment?
Thanks in advance,

As a side note, we've got around 150 files with similar issues. Is there
any limit about the maximum files the self-healing daemon can handle? Would
it be safe to manually copy the data from one brick to the other?

on the clients by issuing (
http://linux-mm.org/Drop_Caches):
echo 3 > /proc/sys/vm/drop_caches
If the client still see the file as split brain, you shall have to umount
and mount again the gluster volume.
Hope it helps,
Samuel.

Dear Patric,
That seemed to make the trick because we can now see the file and access it.
Is there any place where it could be documented?
Thanks a lot,

It's a problem of stripped volumes in 3.3.1.
It does not appear on 3.3.0 and it's solved in coming 3.4.

Hi all,
Besides our negative experience about this topic, there's this post:
http://community.gluster.org/q/how-i-can-troubleshoot-rdma-performance-issues-in-3-3-0/
So it's normal that version 3.3 does not work with transport rdma.
Best regards,
Samuel.

Done.
https://bugzilla.redhat.com/show_bug.cgi?id=888174
While testing the system, we found 3.3.0 enables stripped-replicated
volumes and seems to offer a "right" read behaviour in some tests.
Thanks in advance and, please, contact me in case I can offer further help.
Best regards,

Could anyone provide some information how to debug this problem? Currently
the volume is not usable due to the horrible delay.
Thank you very much in advance,

My question is whether, as I've read, rdma transport is not available in
3.3 and I have to use 3.2.7. I've also tried 3.4.rc1 with the same problems
as 3.3
Thanks in advance,

PU but it's not the only scenario (deleting not empyt directory) that
causes the degradation. Sometimes it has happened wihout any concrete error
on the log files. I'll try to make more tests and offer more debug
information.
Thanks for your answer so far,

I don't know from which version on but, if you use the native client for
mounting the volumes, it's only required to have the IP active in the mount
moment. After that, the native client will transparently manage node's
failure.

Samuel.

compared to NFS but, in theory, the rest of scenarios gluster offers better
performance.
Can anyone point to some documentation where I can improve gluster
behaviour? Or any suggestion|idea to improve the storage system?
