Hi
I am not able to find in the documentation an "interoperability matrix"
among different Lustre versions.
In particular I would be interested if Lustre 2.4 and Lustre 2.5 clients
can work with Lustre 2.1 servers.
If I have a look at:

Hi
In our site we are running Lustre 2.1.6.
I have now problems rebuilding the client with
kernel 2.6.32-431.1.2.el6, which is the latest available version of the
Kernel for Scientic Linux 6.4.
As far as I understand the issue is the one documented in:
https://jira.hpdd.intel.com/browse/LU-42

Sorry I realize that the below is a little inaccurate. We did test 2.1.x
servers with 2.5.x clients one time, just not routinely – we did observe a
number of test failures so I would expect a little work to be needed for things
to run smoothly.
Hi
We are migrating from an old Lustre installation composed by 1 MDS and 2
OSS to a new Lustre 2.5.3 installation.
For this second installation we installated from scratch a new MDS + a
new OST and we migrated the data from the old Lustre system).
Problems started when we tried to "move"
retry the mkfs operations (this time they would
be done with the old MDS switched down)
Do you see some better options ?
Thanks, Massimo

Hi
We had a Lustre filesystem composed of 5 OSTs.
Because of a problem with 3 OSTs (the problem is described in the thread
"Problems moving an OSS from an old Lustre installation to a new one"),
we disabled them.
Now we want to reformat (mkfs.lustre --reformat ...) these 3 OSS and
make them

Thanks Rick for this useful summary !
What is not clear to me if maintenance releases will eventually be
available again or if people running production systems will have to
choose among:
1) Buy Intel support contract
2) Move to another filesystem

Hi
We are running Lustre 2.7.0. We have problems with quota on a filesystem.
This filesystem was initially composed of a single OST, and at that time
quota was enable on the MDT simply doing:
lctl conf_param cmshome.quota.ost=u
lctl conf_param cmshome.quota.mdt=u
Nothing was needed on the OS
Any hints ?
Should I try to change (using lctl conf_param) the attribute:
osd-ldiskfs.cmshome-OST0002.quota_slave.enabled
on the new OST from 'none' to 'u' to fix the problem ?
Thanks, Massimo

Hi Massimo,
Since lustre 2.5 (I guess) formatting the OST using the specific
parameter it's no more necessary. You should simply enable it using the
lctl command.
