Hi all!
I’m playing with drbdmanage in a test setup (two node cluster), and “drbdmanage resize” reproducibly fails for me.
Steps to reproduce:
$ drbdmanage new-volume -d 2 test 1
Operation completed successfully
Operation completed successfully
$ # check that everything is ok:
.drbdctrl role:Secondary
volume:0 disk:UpToDate
volume:1 disk:UpToDate
pvc1st02 role:Primary
volume:0 peer-disk:UpToDate
volume:1 peer-disk:UpToDate
test role:Secondary
disk:UpToDate
pvc1st02 role:Secondary
peer-disk:UpToDate
$ drbdmanage list-resources
+------------------------------------------------------------------------------+
| Name | | State |
|------------------------------------------------------------------------------|
| test | | ok |
+------------------------------------------------------------------------------+
$ drbdmanage list-volumes
+------------------------------------------------------------------------------+
| Name | Vol ID | Size | Minor | | State |
|------------------------------------------------------------------------------|
| test | 0 | 1 GiB | 110 | | ok |
+------------------------------------------------------------------------------+
Now everything looks ok on both nodes, volume was created with 1 GB in size.
Let’s resize it to 3 GB:
$ drbdmanage resize-volume test 0 3
Operation completed successfully
BUT:

… and “drbdmanage list-volumes” still shows the volume with 1 GB.
Sometimes I can see a “FAILED” in the “drbdmanage list-volumes” output, but not all the time.
Any ideas?
