Hello list,
according to <http://www.drbd.org/users-guide/s-nested-lvm.html> I
created a nested drbd/lvm resource.
But - how can the drbd device extended?
I have: (1: is 100GB)
# cat /proc/drbd
version: 8.3.7 (api:88/proto:86-91)
GIT-hash: ea9e28dbff98e331a62bcbcc63a6135808fe2917 build by

PV /dev/drbd1 VG replicated lvm2 [100,00 GB / 56,05 GB free]
PV /dev/md1 VG localvg lvm2 [1,81 TB / 1,71 TB free]
And i tried to extend drbd1 with normal LVM commands:
# lvextend -L+20G /dev/mapper/localvg-r1
Extending logical volume r1 to 120,00 GB
Logical volume r1 successfully resized
# cat /proc/drbd

As you can see - nothing happened, drbd1 is still 100GB. pvscan says
the same.

Total: 2 [1,91 TB] / in use: 2 [1,91 TB] / in no VG: 0 [0 ]
Any help is appreciated.
