Hello DRBD Users, I have a problem configuring DRBD. According the manual I use the following commands: * [root at app1 drbd.d]# drbdadm create-md r0* md_offset 8480256000 al_offset 8480223232 bm_offset 8479961088 Found LVM2 physical volume signature 8257536 kB data area apparently used 8281212 kB left usable by current configuration Even though it looks like this would place the new meta data into unused space, you still need to confirm, as this is only a guess. Do you want to proceed? [need to type 'yes' to confirm] yes Writing meta data... initializing activity log NOT initialized bitmap New drbd meta data block successfully created. *[root at app1 drbd.d]# drbdadm attach r0* 0: Failure: (104) Can not open backing device. Command 'drbdsetup 0 disk /dev/sda2 /dev/sda2 internal --set-defaults --create-device' terminated with exit code 10 As you can see I get this error: "*0: Failure: (104) Can not open backing device.*" and can't figure out what is going on. This is a brand new installation. My configuration is: *DRBD* ------------------------------------------------------- # drbd.conf include "drbd.d/global_common.conf"; include "drbd.d/*.res"; ------------------------------------------------------- ------------------------------------------------------- # r0.res global { usage-count yes; } common { protocol C; } resource r0 { on app1 { device /dev/drbd0; disk /dev/sda2; address 192.168.1.106:7789; meta-disk internal; } on app2 { device /dev/drbd0; disk /dev/sda2; address 192.168.1.107:7789; meta-disk internal; } } ---------------------------------------------------------------------- *SYSTEM* RHEL5.6 Linux app1 2.6.18-238.el5xen #1 SMP Sun Dec 19 15:01:34 EST 2010 i686 i686 i386 GNU/Linux *[root at app1 drbd.d]# fdisk -l* Disk /dev/sda: 8589 MB, 8589934592 bytes 255 heads, 63 sectors/track, 1044 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 1044 8281507+ 8e Linux LVM *[root at app1 drbd.d]# ls -la /dev/drbd0* brw-r----- 1 root disk 147, 0 Mar 27 20:38 /dev/drbd0 ------------------------------------------------------------------------------------- I'm really stuck here.
