[DRBD-user] Low.dev. smaller than requested DRBD-dev. size.

[Tim Hibbard]

I had to repartition my shared storage to make some new room and I can't 
figure this problem out.  The APACHE resource works fine and is 
syncing.  However every time I try to get the SAMBA resource up I run 
into problems.  Is there a way to clear any remaining metadata from 
/dev/sdb2?  Is this  a metadata problem?

console:
drbdadm up samba
ioctl(,SET_DISK_CONFIG,) failed: Invalid argument
Low.dev. smaller than requested DRBD-dev. size.
Command 'drbdsetup /dev/drbd1 disk /dev/sdb2 internal -1

I have two partitions identical on two different servers.

Server A:
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       35000   281137468+  83  Linux
/dev/sdb2           35001       60965   208563862+  83  Linux

Server B:
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       35000   281137468+  83  Linux
/dev/sdb2           35001       60965   208563862+  83  Linux


Any help is appreciated.  Looking to be a long night ...

Thanks,
