[DRBD-user] drbd does not find metadata any more

[Michael Schwartzkopff]

Hi,


I tried to upgrade from CentOS 8.0 to 8.1. My installation has a
self-compiled DRBD-9.

After the upgrade my drbd does not start any more. the Status says:

# drbdadm status
r0 role:Secondary
  disk:Diskless
  dev02 connection:StandAlone


Trying to attach to the disk tells me:

# drbdadm attach r0
1: Failure: (119) No valid meta-data signature found.

        ==> Use 'drbdadm create-md res' to initialize meta-data area. <==

Command 'drbdsetup attach 1 /dev/vgDev01/drbd /dev/vgDev01/drbd
internal' terminated with exit code 10


The journal says:

Nov 26 13:05:09 dev01.sys4.de kernel: drbd r0/0 drbd1: meta-data IO
uses: blk-bio
Nov 26 13:05:09 dev01.sys4.de kernel: drbd r0/0 drbd1: ambiguous node
id: meta-data: 1, config: 0


As far as I can see I have meta-data on my disk:

# drbdadm dump-md r0 | head -30
# DRBD meta data dump
# 2020-11-26 13:06:58 +0100 [1606392418]
# xxx.sys4.de> drbdmeta 1 v09 /dev/vgDev01/drbd internal dump-md
#

version "v09";

# bm_offset 3298434183168

node-id 1;
current-uuid 0x45451CABFEB9894F;
flags 0x00000093;
peer[0] {
    bitmap-index 0;
    bitmap-uuid 0xF3394DA3B6073B46;
    bitmap-dagtag 0x0000000000000000;
    flags 0x00000000;
}

(...)


Any idea how to bring my DRBD to life again?

Any help appreciated.


Mit freundlichen Grüßen,
