I forgot to add that all tests were performed with glusterfs 2.0.10rc1
(as 3.0 has no working unify), but the inode/dentry management seems
to be the same in 3.0.

Thanks for these inputs, Krzysztof. We are on this and will update you

Dear all,
Is there an easy way to put a storage brick, which is part of a dht volume,
into some kind of read-only maintainance mode, while keeping the whole dht
volume in read/write state?
Currently it almost works, but files are still scheduled to go to the server
in maintainance mode and in t
Fred,
Would you like to tell us more about the use case ? Like why would you want to
do this ? If we take a brick out, it would not be possible to get it back in (
with the existing data ).
Regards,
Tejas.

Exactly.
Ok. and how many clients mount these volume(s) .. asking so I can understand
how many need to remount if config is changed.

The file system is currently mounted on ~25 of our computing nodes and 5
portal machines.

Hi all,
Is it possible to use a nfs share to serve as a glusterfs server process?? For
example: I have a host that mounts a nfs share from a solaris server under /mnt. Can
I use this /mnt directory for a glusterfs server??
Thanks.

Hi Krzysztof,
Thanks for your replies. And you are right, the server process should be
glusterfsd. But I did mean servers. After two days copying, the two
processes took almost 70% of the total memory. I am just thinking one
more process will bring our servers down.

Hi Chris,
Just to confirm, from the server vol file from your previous post,
you are not even using any performance translators on the server side,
is that correct ?
And the only major activity is the copying ?

Only io-threads. the vol files were generated from gluster-volgen. I

Hi Chris,
I would like your help in debugging this further. To start with, I would
like to get the system information and the test information.
You mentioned you are copying data from your old system to the new system.
The new system has 3 servers.
Problems you saw -
1) High memory usage on c
Thanks, Chris. So no caching performance translators were
used - that's what I wanted to check. I sent another mail
about more debug information. Can you please have a look
and respond when you get some time.
Thanks for all your help.

Tejas.

Memory usage for clients is 0% after copying.

Thanks, Ian.
Fred - the method Ian describes, using self heal, is a good way of doing it
while maintaining gluster semantics and not playing around directly with the
backend.
In a future release, with dynamic volume management, one would be able to do
such things with simple commands with havin
Thanks, Chris. This is very good information to start with.
To summarize this, when you copy lot of small files from
nfs mount to glusterfs mount, the copy is slow and at the end of it
you see the glusterfs servers still holding a lot of
memory after the copy is done. The clients do seem to rele
Chris,
By the way, after the copy is done, how is the system responding to
regular access ? In the sense, was the problem with copy also
carried forward as more trouble seen with subsequent access of
data over glusterfs ?

Tejas,
We still have hundreds of GBs to copy, and have not put the new file
system into the test. So far the clients works all fine. I mean the
commands like ls, mkdir, touch, and etc.
Thanks again for your time.
