[dm-devel] Inconsistancy with multipath -v2 and multipath -ll

[Josef Whiter]

Hello,

This is a sanity check for myself, I just want to make sure I'm not missing
something.  If I set features to be "1 queue_if_no_path" and I run

multipath -v2

I get

[size=12 GB][features="1 queue_if_no_path"][hwhandler="0"]
\_ round-robin 0 
 \_ 2:0:0:0     sdb           8:16  [ready]
 \_ 3:0:0:0     sdf           8:80  [ready]

But if I then do a multipath -ll I get

[size=12 GB][features="0"][hwhandler="0"]
\_ round-robin 0 [active]
 \_ 2:0:0:0     sdb           8:16  [active][ready]
 \_ 3:0:0:0     sdf           8:80  [active][ready]

Now when multipath -v2 is run, the maps arent printed until domap is hit in
coalesce_paths, at which point the mpp has had features set from the
configuration.  Howerver, with multipath -ll, it never hits coalesce_paths, it
just pulls the information out of mpp->params, which is something like

params = 0 0 1 1 round-robin 0 2 1 8:48 100 8:112 100

It doesn't look like the features is getting put into the params list.  My
question is this, is anyone else using features "1 queue_if_no_path", and if you
are do you see the same things I do?  If you are good theres a bug and that
needs to be addressed, if you aren't then would you mind posting your
multipath.conf to see if I've just fudged this all up?  Thank you,

Josef
