Multihomed question: want Lustre over IB andEthernet
Chris,
Perhaps you need to perform some write_conf like command. I''m not sure if this is needed in 1.6 or not.

Balancing I/O Load
We are seeing some disturbing (probably due to our ignorance)
behavior from lustre 1.6.3 right now. We have 8 OSSs with 3 OSTs
per OSS (24 physical LUNs). We just created a brand new lustre file
system across this configuration using the default mkfs.lustre
formatting options. We have this file system mounted across 400
clients.
At the moment, we have 63 IOzone threads running

bad 1.6.3 striped write performance
Hi,
I''m seeing what can only be described as dismal striped write
performance from lustre 1.6.3 clients :-/
1.6.2 and 1.6.1 clients are fine. 1.6.4rc3 clients (from cvs a couple
of days ago) are also terrible.
the below shows that the OS (centos4.5/5) or fabric (gigE/IB) or lustre
version on the servers doesn''t matter - the problem is with the 1.6.3
and 1.6.4rc3 client kernels

How to bypass failed OST without blocking?
Hi
I want my lustre do such things during OST failed: if some file
has stripe data on th failed OST, any operation on the file will
return IO error without blocking, and also at this moment I can
create and read/write new file or read/write files which have no stripe
data on the failed OST without blocking.
What should I do ? How to configure?
thanks!

Lustre Debug level
Hi,
Lustre manual 1.6 v18 says that that in production lustre debug level
should be set to fairly low. Manual also says that I can verify that
level by running following commands:
# sysctl portals.debug
This gives ne following error
error: ''portals.debug'' is an unknown key
cat /proc/sys/lnet/debug
gives output:

How to remove OST permanently?
All,
I''ve added a new 2.2 TB OST to my cluster easily enough, but this new
disk array is meant to replace several smaller OSTs that I used to have
of which were only 120 GB, 500 GB, and 700 GB.
Adding an OST is easy, but how do I REMOVE the small OSTs that I no
longer want to be part of my cluster? Is there a command to tell luster
to move all the file stripes off one of the nodes?

MPI-Blast + Lustre
Anyone have any experience with MpiBlast and Lustre. We have
MpiBlast-1.4.0-pio and lustre-1.6.3 and we are seeing some pretty
poor performance with most of the mpiblast threads spending 20% to
50% of their time in disk wait. We have the genbank nt database
split into 24 fragments (one for each of our OSTs, 3 per OSS). The
individual fragments are not striped due to the

How To change server recovery timeout
Hi,
Our lustre environment is:
2.6.9-55.0.9.EL_lustre.1.6.3smp
I would like to change recovery timeout from default value 250s to
something longer
I tried example from manual:
set_timeout <secs> Sets the timeout (obd_timeout) for a server
to wait before failing recovery.
We performed that experiment on our test lustre installation with one
OST.

Adding OST to online Lustre with quota
Hello,
we wounder whether is it possible to add OSTs to the Lustre with
quota support without making it offline?

that OST was formatted with quota support
we are receiving this error message:

Understanding lustre setup ..
Hello,
I have been reading
http://wiki.lustre.org/images/1/1b/Hadoop_wp_v0.4.2.pdf for setting up
Hadoop over lustre.
Generally in hadoop setup, we have 1 Namenode and various number of datanodes.
If I want to setup the same keeping Lustre as backend, in the document
it is mentioned that:

lustre quota problems
Hello,
I''ve several problems with quota on our testcluster:
When I set the quota for a person to a given value (e.g. the values which
are provided in the operations manual), I''m able to write exact the amount
which is set with setquota.
But when I delete the files(file) I''m not able to use this space again.
Here is what I''ve done in detail:

fsck ldiskfs-backed OSTs?
There are references to running fsck on the lustre OSTs after a crash
or power failure. However, after downloading the ClusterFS
e2fsprogs and building them, e2fsck does not recognize our ldiskfs-
based OSTs. Is there a way to fsck the ldiskfs-based OSTs?
Thanks,

how do you mount mountconf (i.e. 1.6) lustre on your servers?
As any of you using version 1.6 of Lustre knows, Lustre servers can now
be started simply my mounting the devices it is using. Even
an /etc/fstab entry can be used if you can have the mount delayed until
the network is started.
Given this change, you have also notices that we have eliminated the
initscript for Lustre that used to exist for releases prior to 1.6.
