Lol i made it :)
Ok so i thought that it was buggy drbd9 but after 3 days of lost time i
finally made it [image: :)]
Before that fix i had 20mbit/s syncing but after that i have 800mbit/s on
1GBit [image: :)]
Code:
NET | bond0 80% | pcki 13298 | pcko 133286 | si 3879 Kbps | so
807 Mbps | coll 0 | mlti 12 | erri 0 | erro 0 |
drpi 0 | drpo 0 |
NET | eth1 80% | pcki 13298 | pcko 133286 | si 3879 Kbps | so
807 Mbps | coll 0 | mlti 12 | erri 0 | erro 0 |
drpi 0 | drpo 0 |
NET | tap0 0% | pcki 4 | pcko 4 | si 0 Kbps | so
12 Kbps | coll 0 | mlti 0 | erri 0 | erro 0 |
drpi 0 | drpo 0 |
NET | eth2
it was all about stupid config file ..... and accually you need to edit
proper config ....
First of all if you have working drbd9 cluster first stop all VMs and then
all resources on both drbd nodes:
Code:
drbdadm disconnect all
Then you need to edit config (and this is what i was looking for so long)
* /var/lib/drbd.d/drbdmanage_global_common.conf* because editing
/etc/drbd.d/global_common.conf
doesnt work at all [image: :)]
Enter those settings to
*/var/lib/drbd.d/drbdmanage_global_common.conf ON BOTH NODESCode:# it must
be content of /var/lib/drbd.d/drbdmanage_global_common.conf !!!! common {
disk { on-io-error detach; no-disk-flushes ; no-disk-barrier; c-plan-ahead
10; c-fill-target 24M; c-min-rate 10M; c-max-rate 100M; }. net { #
max-epoch-size 20000; max-buffers 36k; sndbuf-size 1024k ; rcvbuf-size
2048k; } } *
Then simply restart drbd by:
*Code:/etc/init.d/drbd restart*
And thats it. Syncing should be at 800mbits [image: :)]
In you have 10GBit just change c-max-rate to 1000M
Play with those settings
