>From the online DRBD user gude, to enable online verification according to chapter 6 ('Enabling on-line verification') we need to add a line to the syncer section of the resource: verify-alg algorithm; # where algorithm is supported by kernel, eg: md5 / sha1 / crc32c Under Appendix A for drbd.conf however it says to add the line: data-integrity-alg alg; We're using drbd-8.2.5 and have tried both options but can't get either to work. Using 'data-integrity-alg' spits back an error when DRBD starts saying that it found an unknown option in the conf, whereas using 'verify-alg' (with md5 or sha1) gives this message in the syslog when DRBD starts: localhost kernel: drbd0: data-integrity-alg: <not-used> The user guide says that the algorithm used can be "any message digest algorithm supported by the kernel crypto API in your system's kernel configuration." Would we get this messages because the linux kernel doesn't support cryptography? We're running Fedora 8 so this would be surprising. How to find out which crypto algorithms the kernel supports? It might be worth adding a comment to the user gude about how to do this. Cheers
