G'Day all,
I put this question to another member of the list privately, but I thought
it would be good to ask of the whole list, if ZFS is supported for managing
a large pool of disks in a typical OSS node, could LVM be used with a
stripped LV configuration?
Since LVM is rock solid and most likel
Hi Sid,
Start here https://wiki.lustre.org/LNET_Selftest
That should get you near wire speed numbers and you can use it to play
around with your network tunables.
After that, obdfilter-survey, mdtest, IOR and fio amongst others will help
you determine hero and average numbers for your whole I/O
G'Day all,
What sort of transfer speeds should I expect to see from a client writing
a 1G file into the Lustre storage via RoCE on a 100G ConnectX5 (write block
size is 1M)?
I have done virtually no tuning yet and the MTU is showing as "active 1024".
If you have any links to share with some per
Hi everyone.
Any idea when we’ll see support for OFED 5 in an upcoming Lustre release? The
2.14.0 wiki page states "OFED: inkernel” in the test matrix……
Our IB fabric is based on Mellanox HDR switches and host adapters.
Thanks.

Dear Zeehan,
In our case, it looks like that the removed OST is disappeared. However,
sometimes we feel that some "shodow" of the removed OST still exists in
the Lustre file system.
In our system, running "lctl get_param osc.*.conn_uuid" it shows:
osc.chome-OST-osc-MDT.ost_conn_uuid=192.
Dear Etienne,
Thank you very much for this information, which very interesting.
Will it be available in Lustre version 2.14 ? Hope that the Lustre
manual could also be updateded for the corresponding usage. Then
we would be happy to test it.
Best Regards,
T.H.Hsieh

Dear Tung-Han, even during all the above steps the OST still appears? we
did the same for 3 OSTs in our centre and they disappeared correctly.

Dear Zeeshan,
Yes. We did lfs_migrate to move data out of the OST which we are
going to remove, and then deactivate it, and then unmount it. We
have verified that after the whole process, no data lost, but only
the total space of the Lustre file system decreased due to the
removed OST.
Best Regar
Did you unmount the OST ? remember to lfs_migrate the data otherwise old
data would give errors
