Hi all,
Could you suggest me a guide to tune the system? my servers are very
slow with drbd.. I'm installing xen domUs on mirrored devices and I've
noticed that the disks speed of domUs are really slower than wihout
drbd.
Maybe I should tune kernel and network parameters?
This is my configuration:
global {
       usage-count yes;
}
common {
       protocol C;
       disk {
               on-io-error detach;
       }
       syncer {
               verify-alg md5;
               rate 33M;
       }

}
