This is great news!
For the future releases, will the client ever be part of the stock
kernel? What is the status of SNS? This is an important feature for
many people and it seems people are are shying away from Lustre and
going to other solutions solely based on this feature.

At our lab we deal with a lot of images. Each image is about 4-6Gb average.
We want to use Lustre for processing the image and place it on more
reliable storage such as 3140/NetApp for backups. I was wondering if

technologies together so
there is.

Lustre is a parallel filesystem where NFS is not.
The advantage of NFS is its native for many Unix systems and is widely
available. The advantage of Lustre is its performance.

I know the underlying filesystem for Lustre is ext3+extends, but I was
wondering does Lustre use B-Trees in its logical layout meaning once a
client tries to access its data does it actually use a btree for its
access/retrieval? As a matter of fact, do most clustered parallel file

This data is really not important. When I tried to remove it I keep
getting, "Numerical result out of range".
Is there something else I can do?

Thankyou.
I will try to recover them. I would have to wait for the weekend to do
that because I can't afford to down a OST during work hours

To do the ll_recover_lost_found_objs, can we have everything mounted
up? Or is it recommended we unmount everything?
Also what to do when we see ? for the file attributes. Most likely
these files are gone, how can we remove them from the system all
together?
TIA

Thanks Brian. This answers a lot of questions.
Thanks for the great insight.

We have been experiecing problems recently, where our Lustre
filesystem is becoming read-only (we can't even see our data).
For example when I invoke 'ls' or 'find'
ls: .: Read-only file system
find: cannot get current directory: Read-only file system
The client version is:
lustre: 1.6.6
kernel
in other words, reboot all of your clients?

We previously had a filesystem and we removed its MGS/MDS and its
OSTS. We created a new filesystem and everything is fine now. However,
We still see messages like this:

For its worth, we gave up on backing up our MDS because of its sheer
size and the contents of our filesystem. We have close to 40TB of
space with very small files. Backing up MDS without LVM snapshot took
almost 5 days.
Its probally better to have a backup of your most important files and

I suggest creating a new filesystem and rsync the data over the
network. I would not over complicate the situation.

I have added 2 volumes onto my existing filesystem.
mkfs.lustre --fsname lfs002 --ost --mgsnode=mg...@tcp /dev/lustrevg/lv03
mkfs.lustre --fsname lfs002 --ost --mgsnode=mg...@tcp /dev/lustrevg/lv04
I even managed to mount up the OSTS (each are 2TB)
However, on the clients we don't see the extra
Lustre by NFS using the kernel export nfs daemon, try to disable that.
