Hello all DRBDers,
Great product!
My DRBD setup is as follows:
2 hosts with each:
2x 1TB seagate SATA software RAID1
LVM on top of that
crossover gigabit link between the two.
My drbd.conf is attached.
the problem I am experiencing is that the maximum transfer rate is too
slow.
as in the config file drbd7 mirrors a logical volume mounted on dom0
when i run dd on that lv:
# dd if=/dev/zero of=300meg.file bs=1M count=300 oflag=direct
300+0 records in
300+0 records out
314572800 bytes (315 MB) copied, 39.5295 seconds, 8.0 MB/s
Any tips would be greatly appreciated!
Kind regards,
Coert
