I am trying to setup two systems with two replicated volumes in two cluster
configuration. I am not quite sure what the best approach is, but I tried it in
two different ways. One is to create multiple volumes in a single resource like
the example in the drbd.org documentation and had them configured like the
following on both nodes:
resource r0 {
volume 0 {
device /dev/drbd0;
disk /dev/GROUP0/AOSman;
flexible-meta-disk internal;
}
volume 1 {
device /dev/drbd1;
disk /dev/GROUP0/AOScon;
flexible-meta-disk internal;
}
on FMAOS1 {
address 10.0.5.65:7788;
}
on FMAOS2 {
address 10.0.5.66:7788;
}
}
However that yielded the following results when I did a "cat /proc/drbd"
fmadmin@FMAOS1:/etc/drbd.d$ cat /proc/drbd
version: 8.4.3 (api:1/proto:86-101)
srcversion: F97798065516C94BE0F27DC
0: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r-----
ns:180 nr:0 dw:180 dr:7513 al:5 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
1: cs:Connected ro:Secondary/Secondary ds:Diskless/Diskless C r-----
ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
I then tried to define two resource files for two different resources:
fmadmin@FMAOS1:/etc/drbd.d$ sudo cat r0.res
resource r0 {
on FMAOS1 {
volume 0 {
device /dev/drbd0;
disk /dev/GROUP0/AOSman;
flexible-meta-disk internal;
}
address 10.0.5.65:7788;
}
on FMAOS2 {
volume 0 {
device /dev/drbd0;
disk /dev/GROUP0/AOSman;
flexible-meta-disk internal;
}
address 10.0.5.66:7788;
}
}
fmadmin@FMAOS1:/etc/drbd.d$ sudo cat r1.res
resource r1 {
on FMAOS1 {
volume 0 {
device /dev/drbd1;
disk /dev/GROUP0/AOScon;
flexible-meta-disk internal;
}
address 10.0.5.65:7789;
}
on FMAOS2 {
volume 0 {
device /dev/drbd1;
disk /dev/GROUP0/AOScon;
flexible-meta-disk internal;
}
address 10.0.5.66:7789;
}
}
That also yielded the following:
fmadmin@FMAOS2:/etc/drbd.d$ cat /proc/drbd
version: 8.4.3 (api:1/proto:86-101)
srcversion: F97798065516C94BE0F27DC
0: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r-----
ns:0 nr:180 dw:180 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
1: cs:Connected ro:Secondary/Secondary ds:Diskless/Diskless C r-----
ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0
node already registered
I am not sure what Diskless/Diskless really means, I suspect that whatever is
causing that may be causing my issue. Nor, am I sure if either of the two ways
re correct or if both are a way to do it.
I also see the following when restarting the drbd service:
[
create res: r0 r1
prepare disk: r0 r1
adjust disk: r0 r1:failed(apply-al:255)
adjust net: r0 r1
]
[ OK ]
Any help or pointing to the right direction would be extremely appreciated.
