Hi all,
Previously we've been using DRBD kernel 8.4.3 and userland tools 8.4.3.
We've just loaded a new mirror pair with kernel module version 8.4.6 and
tools 8.9.2.
However, some things have broken because the create /dev/ device name is
not matching what is expected - here is an example config:
resource drbd0061 {
protocol C;
net {
allow-two-primaries;
}
disk {
on-io-error detach;
}
on machine1 {
device /dev/drbd0061;
disk /dev/vg_ssd/vol0061;
address 10.0.0.6:7001;
meta-disk internal;
}
on machine2 {
device /dev/drbd0061;
disk /dev/vg_ssd/vol0061;
address 10.0.0.7:7001;
meta-disk internal;
}
}
This used to create a device:
/dev/drbd0061
However, the device now created is:
/dev/drbd61
without the leading 0s in the number, on the primary machine.
This therefore breaks other associations which expect "/dev/drbd0061" in
entirety to be present.
I can't find any mention of this as a change in the release notes. It's
almost as if it's not recognising my desired configured device name (and
defaulting to another minor), or using a sprintf now formatting using a
%d rather than %s for the device name.
Is there a specific problem with my configuration, was there a planned
change in the source, or is this a bug introduced?
Thanks in advance for any input.
Charles.
