Hello,
I am trying to setup drbd volumes on top of LVM logical volumes and
want to keep the existing data on the logical volumes. I found a HOWTO
for that, but when I try to create the metadata with 'drbdadm create-
md', I get:
md_offset 0
al_offset 4096
bm_offset 36864
Found some data
==> This might
destroy existing data! <==
Do you want to proceed?
[need to type 'yes' to
confirm]
And a test on a less important machine showed that it really destroyed
data.
This is my resource file:
resource jovelin {
volume 1 {
device /dev/drbd1;
disk
/dev/vg0/home;
flexible-meta-disk /dev/vg0/home_metadata;
}
volume
2 {
device /dev/drbd2;
disk /dev/vg0/vservers;
flexible-meta-disk /dev/vg0/vservers_metadata;
}
on tristan {
address 129.217.5.65:7789;
}
on isolde {
address
129.217.5.66:7789;
}
}
Why does drbdadm create-md destroy data on the logical volume, though I
defined metadata to be an external volume? What can I do now to create
the drbd device without losing data?
Regards
Christoph
