I'm trying to setup DRBD for the first time on a 2-node cluster using DRBD
over a lvm lvgroup. I believe I have set it up just as outlined in sec10.2
of the DRBD User's Guide. My r0.res is setup with:
resource 0 {
volume 0 {
device /dev/drbd1;
disk /dev/vg_ajksjnusrv/lv_shared;
meta-disk internal;
}
on ajk-s-jnusrv1.jnu.nwsar.gov {
address 10.0.64.1:7789;
}
on ajk-s-jnusrv2.jnu.nwsar.gov {
address 10.0.64.2:7789;
}
}
lvscan shows
ACTIVE '/dev/vg_ajksjnusrv/lv_shared' [1.91 TiB] inherit
drbdadm create-md r0 works fine. But when I try drbdadm up r0 I get
1: Failure: (104) Can not open backing device.
Command 'drbdsetup attach 1 /dev/vg_ajksjnusrv/lv_shared
/dev/vg_ajksjnusrv/lv_shared internal' terminated with exit code 10
/var/log/messages says
block drbd1: open("/dev/vg_ajksjnusrv/lv_shared") failed with -16
I've been searching the web the last 2 days but have not been able to see
where I'm going wrong. Any help of where to look next would be greatly
appreciated.
