In the Lustre 2.1 manual, mds-survey is mentioned, and google finds the
source at:
http://git.whamcloud.com/?p=fs/lustre-release.git;a=tree;f=lustre-iokit/mds-survey;hb=HEAD
It doesn't seem to work on Lustre 1.8. Should it?
The error I get is:
[root at mds03 client]# thrhi=64 file_count=200000 sh /root/mds-survey
error: setup: Operation not supported
Can't setup echo-client
[root at mds03 client]# thrhi=64 file_count=200000 sh /root/mds-survey
error: attach: LCFG_ATTACH File exists
Can't setup echo-client
What I'm actually trying to do is migrate an MDS to new hardware - and
I'd like to perform some basic tests - partly to see if using LVM has a
significant performance impact.
