On my particular setup i have sha1 set up, and i never tried crc32c. I will give it a shot sometime, but since thespeed of the verification is affected by the utilization of the resources, i can't give you a baseline for this algo. I can tell that the progress shows 100% from the start(meh), and...
According here :https://www.drbd.org/en/doc/users-guide-90/s-dm-setupopts it should the verify-alg option, and the entry is also visible in the config file. You can run #drbdadm verify all and the online verification will start.
hi,
i guess you are using drbd veersion 9+ and more important you configured it using drbdmanage. Try setting the verify algo using
drbdmanage net-options --verify-alg crc32c --common
It gets replicated among drbd nodes.
