does the configuration below make any sense, is it allowed by lustre?
The setup with lustre-2.5.3 (intel):
Two separate Lustre filesystems, fs1 and fs2, each having it's own set of
servers for separate MGT/MDT, mds01 and mds02, respectively
Can one have OSTs created on SAN block devices belonging to these two
Lustre filesystems mounted on the same OSS server?
mds01 # mkfs.lustre --reformat --mgs /dev/sdb
mds01 # mkfs.lustre --reformat --fsname=fs1 --mdt --index=0
mds02 # mkfs.lustre --reformat --mgs /dev/sdb
mds02 # mkfs.lustre --reformat --fsname=fs2 --mdt --index=0
The OST SAN volumes are presented to both oss01 and oss02 servers:
oss01 # mkfs.lustre --reformat --fsname=fs1 --ost --index=0
--failnode=oss02@tcp0 --mgsnode=mds01@tcp0 /dev/sdb
oss02 # mkfs.lustre --reformat --fsname=fs2 --ost --index=0
--failnode=oss01@tcp0 --mgsnode=mds02@tcp0 /dev/sdc
oss02 # mkfs.lustre --reformat --fsname=fs2 --ost --index=1
--failnode=oss01@tcp0 --mgsnode=mds02@tcp0 /dev/sdd
I will mount the filesystems like this:
mds01 # mkdir -p /lustre/fs1-mgt01; mount -t lustre /dev/sdb
mds01 # mkdir -p /lustre/fs1-mdt01; mount -t lustre /dev/sdc
mds02 # mkdir -p /lustre/fs2-mgt01; mount -t lustre /dev/sdb
mds02 # mkdir -p /lustre/fs2-mdt01; mount -t lustre /dev/sdc
oss01 # mkdir -p /lustre/fs1-ost01; mount -t lustre /dev/sdb
oss02 # mkdir -p /lustre/fs2-ost01; mount -t lustre /dev/sdc
oss02 # mkdir -p /lustre/fs2-ost02; mount -t lustre /dev/sdd
oss02 # umount /lustre/fs2-ost02
oss01 # mkdir -p /lustre/fs2-ost02; mount -t lustre /dev/sdd
As the result oss01 will have fs1-ost01 and fs2-ost02, and oss02 fs2-ost01.

Call For Participation - Abstracts Due Feb 12th
LUG 2016 is the primary event for technical presentations and discussions on
the Lustre parallel file system. This year's conference is being held in
Portland, OR, from April 5-7, 2016.
Call for Presentations
OpenSFS relies on the real world experience of the open source Lustre
community members to provide valuable sessions to LUG attendees. We're
pleased to extend a call for presentations to solicit topics from Lustre
The over-arching goal of the conference is to provide a forum for end user
sites to share knowledge and experience with their peers. With that in mind,
the LUG Program Committee will prioritize abstracts from end users and their
The LUG planning committee is looking for the following submission topics:
* Best practices in deploying, monitoring and operating Lustre
* Case studies/experiences using newer Lustre releases/features
* Non-traditional deployment (for example from members of the
We are also looking for presentations related to specific development
challenges, new feature development, project updates, edge-case
implementations, and more. We are only interested in development that is
freely released to the community.
To submit an abstract please visit the LUG 2016 Call for Presentation
Submission Website <https://easychair.org/conferences/?conf=lug2016> .
The abstract submission deadline is February 12, 2016. No submission
extensions will be granted.
Abstracts should be a minimum of 250 words and should provide a clear
description of the planned presentation and its goals. If the presentation
describes new development or products then the abstract is required to
detail how the development or product will be made available to the Lustre
community. Authors must disclose if their presentations are vendor-neutral
or promoting a product at abstract submission time.
Promotional presentations are frowned upon. Presentations that are
vendor-neutral are strongly preferred. Speaking slots are available for Gold
sponsors wishing to present vendor-specific and promotional presentations.
Sponsorship details are available on the LUG web site
All LUG presentations will be 30 minutes, with a total of 25 speaking
opportunities available. Accepted presentations will be subject to panel
review three weeks in advance of LUG 2016.
With the ongoing growth and outstanding progress of the Lustre community,
LUG 2016 promises to be an exciting and informative event. Registration
details and additional information will be available in the coming weeks on
the LUG web site <http://opensfs.org/events/lug-2016/> . We look forward to
