Hi,
when trying to update clients from 2.9 to 2.10.0 (on CentOS-7) I
received the following:
"Package lustre-client is obsoleted by lustre, trying to install
lustre-2.10.0-1.el7.x86_64 instead"
and then the update failed (to my guessing due to the fact that
zfs-related packages are
related to the virtual machines?
Just curious here.
Thanks,

Hi,
I have been playing around with Lustre on virtual servers (mainly with
the purpose of gaining some experience).
I have three (physical) machines, and each one have a virtual machine on
them (KVM). On one of the virtual machines there is an MDS and on two of
them there are OSS:es
test looks like it is working to me.

Hi,
I'm trying to use lnet selftest to evaluate network performance on a
test setup (only two machines). Using e.g., iperf or Netpipe I've
managed to demonstrate the bandwidth of the underlying 10 Gbits/s
network (and typically you reach the expected bandwidth as the packet
size increases).
Regarding clients and OSS on same physical server. Seems to me the
problem is not (directly) related to the amount of memory on the
machine, but instead to different applications "competing" for the memory?
Could this possibly be resolved by running lustre in a virtual machine?
Or would there
Thanks a lot!
Did found the "--disable-server" and that seemed to work (sort of),

Do you have any general advice considering that we want CentOS-7.2 on
the clients? We have happily been using 2.5.3 for quite some time now

Hi,
I want to build RPMS for 2.5.3 on CentOS-7.2 (the other option would be
to use 2.8.0, but since we don't need the news in 2.8.0, and since I've
heard 2.5.3 would be more stable I opted to go for 2.5.3).

Will start working with this new version as soon as possible.
At this point I have a few questions:
the lustre server kernel is based on
kernel-3.10.0-327.3.1.el7.x86_64.rpm
surely this means that the clients should be on the same version of the
kernel (i.e., 3.1, but the

yesterday I had an incident where the system disk of one of my servers
(MDT/MGS) went down, but the raid could be rebuilt and the system went
up again.
However, in the event of a complete failure of the system disk (assuming
all relevant "lustre disks" are still intact) is there a clear

Hi!
Short question (using lustre 2.5.3). Have added a new OST and about to
remove a faulty one. After deactivating it I would like to migrate the
data from the faulty one, in chapter 14 the command:

is given, and in chapter 19:

Hi again,
We are running lustre 2.5.3 on a small system, consisting of one
combined MGS/MDT and four combined OSS/OSTs. One of the OSS/OSTs has
faulty hardware, and need to be replaced. The procedure I plan on using
is the following.
1. Deactivate the faulty OSS.
2. Make a file-level backup
Thanks!
If I understand correctly this is taken care of by
tar czvf {backup file}.tgz --xattrs --sparse .
(which should work on CentOS-6.5)?

Hi,
rather new to lustre, and read the following in the manual:
For better performance, we recommend that you create RAID sets with 4
or 8 data disks plus one or two parity disks.
We were experimenting with OSTs with 6 disks, and tried raid set of both
4 and 5 disks (raid5). While testing
