Hello all.
I've just recently had the time to test DRBD myself. Now I am wondering
if my initial test result are somewhat normal for professional equipment.
Im running on 2 identical dell PE2850:
controller LSI Logic 53C1030 Ultra 320 SCSI
disk 6x hdd in raid10
cpu 2x dualcore 2.8ghz xeon
ram 512mb (which is what is made available to this os through grub
config - xen servers)
on the initial sync, and on addition resyncs i get the following:
drbd0: Began resync as SyncSource (will sync 1951768 KB [487942 bits set]).
drbd0: Resync done (total 34 sec; paused 0 sec; 57404 K/sec)
-----
with bonnie++ tests i get: (where the drbd resource is mounted on
/tmp/test/ )
xentest1:/tmp/test# bonnie++ -u 0 -d /tmp/test/

Are these normal results for equipment equal to this?
