Hello DRBD-user group,

 

I have an optimization problem when formatting the filesystem on a drbd
partition;

 

When I type the following command :

 

mkfs.ext4 –m 0 /dev/drbd0

 

I get this warning :

L'alignement de /dev/drbd0 est décalé de 3072 octets.

Cela peut induire de très mauvaises performances, il est suggéré de
(re)-partitionner.

 

English translation :

/dev/drbd0 alignment is offset by 3072 bytes.

This may result in very poor performance, (re)-partitioning suggested.

 

This drbd resource is configured on a soft raid  (disk /dev/md0) of a 2 TB
partition.

 

I have another drbd resource configured on the same server with the same
configuration but a 20 GB partition and I don’t get the warning for this
one.

 

I took an afternoon on this, but I couldn’t fix it.

Does somebody have any idea ?

 

Thanks,

 

Raphaël LOUIS
