• More than two nodes in one level (i.e. without device stacking)
• Full data logging (with drbd-proxy-3)

later

• Optional load balancing of READ requests.
• Never report false-positives with the data-integrity-alg checks.
• Use the crypto API in a way that we can utilize multiple CPU cores to do checksums
• Support DIF and DIX.
• Optionally deal with read errors in a way that the BBR (bad block relocation) of a drive can kick in
• move the cpu-mask from the syncer section to the host section, since it might be necessary to have that different on the systems.
• Offer an improved resync mode, that deals gracefully with thin provisioned storage. Currently a checksum based resync already has this property. The improvement will be a special mode, that just does not rewrite blocks containing only zeros.
