One drbd server crashed and since rebooting I have been unable to bring up one
of the four drbd resources it hosts. The resource (r0) is primary on the server
concerned. The other 3 resources (one primary and two secondary) are working
correctly. The error message is:
No valid meta data found
Command 'drbdmeta 0 v08 /dev/sdb internal apply-al' terminated with exit code
255
DRBD Version:
version: 8.4.3 (api:1/proto:86-101)
srcversion: 6551AD2C98F533733BE558C
Linux Version:
Linux server 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015
x86_64 x86_64 x86_64 GNU/Linux
The secondary server for r0 has not been rebooted and reports the following:
version: 8.4.3 (api:1/proto:86-101)
srcversion: 6551AD2C98F533733BE558C

Device sdb is a 1.8 GB GPT disk with around 90% used so ideally I don't want to
recreate it.
I'm fairly certain that the secondary is in sync with the primary as the
resource is used for server backup. Is it possible to copy the meta data from
the secondary to the primary or is there a better way to get the primary r0
back online?
Many Thanks
John McAlinden
