Sorry to have bothered you - works now.
I have set /sys/fs/lustre/timeout=3000, quite brutally, to make things go verrry slowly, and after 25
minutes the mount was there.
Which control aka timeout-parameter _should_ I have tuned instead in such a
situation?
Regards,
Thomas

Hi all,
in a Lustre 2.10, CentOS 7.4 test system, I have a pair of MDS, format command
was
> mkfs.lustre --mgs --mdt --fsname=test --index=0
--servicenode=10.20.1.198@o2ib5 --servicenode=10.20.1.199@o2ib5
--mgsnode=10.20.1.198@o2ib5 --mgsnode=10.20.1.199@o2ib5 /dev/drbd0
I added some OSS and clients, everything working.
Then I switched off 10.20.1.198 and mounted my MGS/MDT on 10.20.1.199.
All OSS and clients connected, everything working.
Now I try to add a client that was never there before,
> mount -t lustre 10.20.1.198@o2ib5:10.20.1.199@o2ib5:/test /lustre/test
But this client only tries to connect to 10.20.1.198@o2ib5 - and fails.
The log says

all of which seems logical but not wanted - where is my 10.20.1.199@o2ib5 ?
Of course I can 'lctl ping 10.20.1.199@o2ib5'.
And I have since umounted on one of the older clients, unloaded the Lustre modules, and mounted again
- works.

Thomas
