[DRBD-user] drbd raid stays at state peer: Connecting

[Christoph Pleger]

Hello,

on two servers, I created two drbd resources, where one server is the
primary for the first resource and the other server is the primary for
the second resource. A dump of my setup is attached.

Unfortunately, the drbd RAID works for the first resource, but it does
not for the second. "drbdadm status" since almost two days now shows on
the first machine:

grobi role:Primary
  volume:2 disk:UpToDate
  peer role:Secondary
   
volume:2 replication:Established peer-disk:UpToDate

hastig
role:Secondary
  volume:1 disk:Inconsistent
  volume:3 disk:Inconsistent
 
volume:4 disk:Inconsistent
  volume:5 disk:Inconsistent
  peer: Connecting

On the second machine, it shows:

grobi role:Secondary
  volume:2 disk:UpToDate
  peer role:Primary
   
volume:2 replication:Established peer-disk:UpToDate

hastig role:Primary
 
volume:1 disk:UpToDate
  volume:3 disk:UpToDate
  volume:4 disk:UpToDate
 
volume:5 disk:UpToDate


Any idea what is going on and what I can do now to make RAID hastig
work? The two machines are in the same network and I have disabled all
local ip filter rules, so I do not know what might be blocking the
connection between the two servers ...

Regards
  Christoph
