[Lustre-discuss] lfs 1.8.3 print ost_conn_uuid

[Heiko Schröter]

Hello,

it would be nice that lfs prints out the ACTIVE (in our case) tcp connection. i.e:

cluster1 ~ # lfs osts -i
OBDS:
0: scia-OST0000_UUID INACTIVE
1: scia-OST0001_UUID INACTIVE
2: scia-OST0002_UUID INACTIVE
3: scia-OST0003_UUID INACTIVE
<snip><snap>

I've patched lfs accordingly and if it is of general interest would put it in bugzilla.
The content of /proc/fs/lustre/../../ost_conn_uuid is read.
So it should work with other connection types as well, but has not been tested.
