Today I did a little test to see if I could configure DRBD on encrypted LVs and what I found is it didn't work for me... Because the servers are located in a colo, security for the servers is the main reasoning.
All seems to go good until I tell DRBD to mirror filerA logical volume(/dev/vg/data) to filerB LV (/dev/vg/data). I then received errors on the console like this, over and over:
"Block drbd0: open("/dev/vg/data") failed with -16"
I then rebooted to Ubuntu CD to look at the LVs and.. they were all gone. The only thing the partitioner sees is the two partitions I created, one for /boot the other for logical volumes, but all my lvm tables were gone. I was able to repeat this issue on both my filers.
So my question is..
a) can this even be done, encrypting the filesystem then configureing DRBD
b) if encryption can be done, is my approach wrong?
Thank you in advance for your time.
