[Lustre-discuss] Problems switching the OSS and getting Lustre to restart correctly.
I have a simple configuration where I''d like to switch the OSS to a
different server. The OST is on external storage and will remain the
same. I''ll switch cables to the storage between servers. The MDS, MGT
and client remain the same. After rebooting all machines, Lustre seems
to start correctly again on the MDS/MGT and OSS - no console messages. I
can also mount the client without any console errors, however an ls
command on the client mounted device hangs.
entries in /var/log/messages on the MDS indicate there was an error from
the old OSS - which isn''t involved in the Lustre configuration at this
point:
Lustre: 5012:0:(peer.c:238:lnet_debug_peer()) 172.22.14.245@tcp
<mailto:172.22.14.245@tcp> 2 up 8 8 8 8
7 0
OLD OSS = 172.22.14.245 (not in use - but still on the network)
Current OSS IP = 172.22.14.166
MDS/MGT = 172.22.14.101
Client = 172.22.14.100
How do you properly switch out the OSS and restart using the same OSTs?
Thanks
Tim

[Lustre-discuss] Problems switching the OSS and getting Lustre to restart correctly.
Thanks - tunefs worked fine on MDS/MGT combo server.
On OSS tunefs fails with "unsupported features" message. Both MDS/MGT
and OSS are running 2.6.9-42 kernel.
I''d expect tunefs to fail on both servers if the kernel is to old.
I''m
using Lustre 1.5.95.
