Hi everyone! Can someone explane me how to corectly set up read balancing globaly, for all my drbd devices? All existing and all I will create in future. In this article

I read about configuration file - disk section. Is it mean /etc/drbd.d/global\_common.conf ? I can’t find this in commented part of disk section. And how I must corectly write this parameter? Maybe some example 😉

If you want it to apply to every DRBD device, you would put it in the `global_common.conf`, within the `common` then `disk` section.
From the `drbd.conf` man page:
```plaintext
read-balancing method
The supported methods for load balancing of read requests are prefer-local,
prefer-remote, round-robin, least-pending, when-congested-remote,
32K-striping, 64K-striping, 128K-striping, 256K-striping, 512K-striping and
1M-striping.
The default value of read-balancing is prefer-local. This option is available
since 8.4.1.
```
So something like this could be an example:
```plaintext
common {
...
disk {
# size on-io-error fencing disk-barrier disk-flushes
# disk-drain md-flushes resync-rate resync-after al-extents
# c-plan-ahead c-delay-target c-fill-target c-max-rate
# c-min-rate disk-timeout
read-balancing least-pending;
}
}
...
```
If you only wanted it to apply to specific DRBD resources, you would put it within the `disk` section of that specific `resource` configuration rather than the `global_common.conf`
