Hello!
I had out of sync blocks in my two node DRBD 8 cluster.
So I did the usual command to start the resync:
drbdadm disconnect <resource>
drbdadm connect <resource>
This worked as expected for the first smaller resource.
Then I did it for the second bigger one. Here the disconnect stated:
Command 'drbdsetup-84 disconnect ipv4:10.23.8.227:7789 ipv4:10.23.8.226:7789' did not terminate within 5 seconds
Then the
drbdsetup status --verbose --statistics
command hung for long time.
This came back and all looked ok.
BUT:
$ drbd-overview
0:??not-found?? Connected Primary/Secondary UpToDate/UpToDate
1:??not-found?? Connected Primary/Secondary UpToDate/UpToDate
10:??not-found?? Connected Secondary/Primary UpToDate/UpToDate
11:??not-found?? Connected Secondary/Primary UpToDate/UpToDate
What can I now do to get this working again?
Some more info:
