Hi, Haoyang
Maybe you should rebuild the MOFED with new kernel first, then rebuild
lustre server package.
1) about restore
I think you can try switch to the old kernel first, but as you said, you
have rebuild the MOFED under the new kernel, so once you go back to the old
kernel you need to

Hi,
you can enable user quota on mgs by

lctl conf_param your_fsname.qouta.mdt=u
lctl conf_param your_fsname.qouta.ost=u

Hi,
You can find details in lustre manual chapter 34.6.5
When enabling TBF policy, you can specify one of the type(NID, JOBID,
OPCode and
UID/GID )s, or just use "tbf" to enable all of them to do a fine-grained
RPC requests classification and this feature also supports logical
conditional

Hi, all
In one of our lustre filesystems，we found that
1) ls command blocked in some dir but ls --color=never worked.
2) some files can not be accessed, like cat/head/vim/file(i use strace
to trace command "strace file .xxx" , stucked in lstat).

Maybe this is a bug?
We never hit this before update client to 2.12.5

Thanks for your suggestion.
But , to reboot the OSSs in production under massive IO pressure will make
another long long story .

Hi, Alastair & Mark Hahn
Can mounted lustre filesystem(same version ) impact each other ?
Can network become bottleneck?

Hi,
You can get something from changlog，like
http://wiki.lustre.org/Lustre_2.12.2_Changelog.
BTW，we have tried 2.12.2 server with 2.7.x client & 2.5.x client，not work.

Hi, Mark Hahn
Very appreciate for your detailed reply.
And sorry for the ambiguous description.
For some reasons, we decided not to expand on the lustre filesystem already
exists; so what I want to know is the number of lustre filesystems that a
client can mount on the same time .
Best regards.

Hi, all
Is there a ceiling for a Lustre filesystem that can be mounted in a cluster?
If so, what's the number?
If not, how much is proper?
Does mount multiple filesystems can affect the stability of each file
system or cause other problems?
Thanks!

Hi, Leonardo
Thanks for your reply,
but I found that use vasp-5.4.4 can walk arround this issue,so we do not
intend to upgrade the kernel recently.

Hi all,
we use TBF policy(details:

to limit rpcrate coming from clients; but I do not know how to mapping of
rpcrate to bandwidth or iops.
For example:
if I set a client's rpcrate=10，how much bandwith
Hi all,
we used lustre 2.12.2, hit a strange problem this morning, some file
restored after modify
i modified job.sh, about 1 min later，file restored.
when i copy job.sh to test.sh, then modify test.sh , test.sh not restored.
when i use root to modify job.sh, file not restored; then i use user
I got around this by disable building of Lustre tests
cp rpmbuild/SOURCES/lustre-2.12.4.tar.gz .
tar -xvf lustre-2.12.4.tar.gz
cd lustre-2.12.4/
./configure --enable-server --disable-tests

Hello, I have some question about metadata space.
1) I have ten 960GB SAS SSDs for mdt,after done raid10,we have 4.7TB space free.
after formated as mdt,we only have 2.6TB space free; so where the
2.1TB space go ?
2) for the 2.6TB space, what's it used for?
