[Bug 1866458] Re: drbd not working after kernel upgrade 5.0.x -> 5.3.x

[Rafael David Tinoco]

** Description changed:

+ [Impact]
+ 
+  * One can't manage drbd resources through drbdadm command after kernel
+ has been upgraded to 5.3 (latest HWE kernel).
+ 
+ [Test Case]
+ 
+ $ sudo dd if=/dev/zero of=/.loop bs=1M count=1024
+ 
+ $ sudo losetup --find --show /.loop
+ /dev/loop0
+ 
+ $ cat /etc/drbd.d/r0.res
+ resource r0 {
+         protocol C;
+         startup {
+                 wfc-timeout  15;
+                 degr-wfc-timeout 60;
+         }
+         net {
+                 cram-hmac-alg sha1;
+                 shared-secret "secret";
+         }
+         on drbdfix {
+                 device /dev/drbd0;
+                 disk /dev/loop0;
+                 address 10.250.99.202:7788;
+                 meta-disk internal;
+         }
+         on drbdnon {
+                 device /dev/drbd0;
+                 disk /dev/loop0;
+                 address 192.168.0.2:7788;
+                 meta-disk internal;
+         }
+ }
+ 
+  * Check that with kernel 5.0.0 drbdadm command works fine for the
+ configured resource:
+ 
+ $ uname -a
+ Linux drbdfix 5.0.0-43-generic #47~18.04.1-Ubuntu SMP Mon Mar 2 04:28:21 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
+ 
+ $ sudo drbdadm -v up r0
+ no resources defined!
+ 
+  * And with kernel 5.3.0 it does not:
+ 
+ $ uname -a
+ Linux drbdfix 5.3.0-42-generic #34~18.04.1-Ubuntu SMP Fri Feb 28 13:42:26 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
+ 
+ $ sudo drbdadm -v up r0
+ drbdsetup-84 new-resource r0
+ r0: Invalid argument
+ Command 'drbdsetup-84 new-resource r0' terminated with exit code 20
+ drbdadm: new-minor r0: skipped due to earlier error
+ 
+ [Regression Potential]
+ 
+  * TBD
+ 
+ [Other Info]
+ 
+  * Original Case Description:
+ 
  I am not able to bring drbd resource up after kernel upgrade (5.0 ->
  5.3)
  
  /sbin/drbdadm -v  up amail
- drbdsetup-84 new-resource amail 
+ drbdsetup-84 new-resource amail
  amail: Invalid argument
  Command 'drbdsetup-84 new-resource amail' terminated with exit code 20
  drbdadm: new-minor amail: skipped due to earlier error
