[DRBD-user] drbdadm resize - unrecognized option '--size'

[Dominik Vallendor]

Hello everyone,

today we tried to shrink a drbd device online.
Following the documentation over at: 
https://docs.linbit.com/docs/users-guide-8.4/#s-resizing we ran

"drbdadm resize --size=<new-size> <resource>"

which led to the following error: "drbdadm: unrecognized option '--size'".

After some research we found an archived thread 
(http://lists.linbit.com/pipermail/drbd-user/2012-June/018551.html) 
which mentions that error and confirms it as a bug.
The documentation for drbd 8.0-8.3 uses the old command syntax ("drbdadm 
-- --size=<new-size> resize <resource>") which works, the documentation 
for drbd 8.4 and 9.0 uses a new command syntax which does not work.
I tried this with drdb-utils 8.9.6 and the current 9.5.0 version.

These mistakes in the documentation can be found in the man pages for 
drbdadm as well.

Debug information:
drbd: version: 8.4.10 (api:1/proto:86-101)
drbd-utils:
Version: 8.9.6 (api:1)

Version: 9.5.0 (api:1)
GIT-hash: ee126652638328b55dc6bff47d07d6161ab768db build by 
user at somewhere, 2018-08-23 16:53:06

Could you please confirm this bug and fix the documentation/bug?

Kind regards

Dominik
