Hi
I am very newbie on DRBD...
But I am search with some tricks to improve performance.
I deploy a drbd resource and use this drbd.conf:
global { usage-count no; }
common {
syncer
{
rate 200M;
al-extents 3833;
}
disk {
no-disk-barrier;
no-disk-flushes;
no-md-flushes;
use-bmbv;
}
}
resource r0 {
protocol C;
startup {
wfc-timeout 15;
degr-wfc-timeout 60;
become-primary-on both;
}
net {
sndbuf-size 0;
rcvbuf-size 0;
max-buffers 16384;
unplug-watermark 16384;
max-epoch-size 16384;
cram-hmac-alg sha1;
shared-secret "drbd123";
allow-two-primaries;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
after-sb-2pri disconnect;
}
on kvm-0 {
device /dev/drbd0;
disk /dev/sda3;
address 10.0.0.100:7788;
meta-disk internal;
}
on kvm-1 {
device /dev/drbd0;
disk /dev/sda3;
address 10.0.0.110:7788;
meta-disk internal;
}
}
The net adresses run on gigabyte network cards with crossover
pathcable....
Google's results show me some testimonial that an external meta-disk
can be used to improve some performance...
My question is: Is that true? If yes, how can I do to have external
driver to do meta-disk???
Thanks

não ser por Mim.
