[DRBD-user] 8 Zettabytes out-of-sync?

[Jarno Elonen]

I've got several DRBD 9 resource that constantly show *UpToDate* with
9223372036854774304 bytes (exactly 8ZiB) of OutOfDate data.

Any idea what might cause this and how to fix it?

Example:

# drbdsetup status --verbose --statistics vm-106-disk-1
vm-106-disk-1 node-id:0 role:Primary suspended:no
    write-ordering:flush
  volume:0 minor:1003 disk:UpToDate quorum:yes
      size:16777688 read:215779 written:22369564 al-writes:89 bm-writes:0

      lower-pending:0 al-suspended:no blocked:no
  mox-a node-id:1 connection:Connected role:Secondary congested:no
