[DRBD-user] Failed to create meta-data for DRBD volume

Hi Roland:

Thank you for your reply.

I did not create the LVM thin pool, because LINSTOR does it.

lvs
  LV           	VG     Attr       LSize   Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  data        	pve    -wi-a----- 300.00g
  root         	pve    -wi-ao----  96.00g
  swap         	pve    -wi-ao----   4.00g
  test01_00000 	vg_hdd -wi-a-----  50.01g

(test01 is a new test after the last LINSTOR upgrade)

The backing device was not created manually before, because LINSTOR creates de LV and the .res file

/var/lib/linstor.d/test01.res


Regards

Daniel

Did you actually create  the LVM thin pool you want to use? LINSTOR does
not do that for you.
What is the "lvs" status at the time this fails? Was the backing device
even created, so meta-data can be written?
