[DRBD-user] building v9

Hello I am having troubles building the v9 module although I tried with various releases and against many kernel versions. With branch drbd-9.0 and drbd-9.0.26-0rc2 against stock Ubuntu 5.8.0-31-generic In file included from /root/tp/drbd/drbd/drbd_main.c:19: ./include/linux/vermagic.h:6:2: err

Re: [DRBD-user] building v9

Hey. Here is some update on my attempts to build the v9 module on Ubuntu. I managed to build it on Slackware Linux before, but for some reason all my attempts are failing on Ubuntu/focal. Ubuntu 20.04.1 LTS 5.8.0-31-generic vs. 5.9.11.xenreiser4 /usr/local/bin/spatch --version spatch version

Re: [DRBD-user] building v9

Hope this helps... My building issues were solved already, once I reverted to longterm 5.4, as I stated in my answer to Yannis in this very thread. In my answer to Christoph, I was rather contradicting the fact that Coccinelle could be avoided in case of supported kernels. And yes, I also

[DRBD-user] diskless on purpose

Hello imagine a three node cluster, with a resource `r1` configured across node1 and 2. How to reach the very same resource but diskless on node3? I suppose I should look into NVME-over-TCP or iSCSI but it should be possible with DRBD itself, right? If so, would that be with both v8 and/or

Re: [DRBD-user] diskless on purpose

So did you define an address? :) Sorry, I was baffled with the way DRBD node communicate, and mistaken a listening port with an SCSI target. It works! It's pretty cool) I've tried with Protocol A and I could also mount a resource on node3 indeed. Hmm but what's the logic behind such a set

Re: [DRBD-user] drbd with a third node diskless - how ?

l and rely on the DRBD diskless feature instead. It is possible to build a fully-convergent farm that way, without the need of iSCSI nor Linstor. Just in case you're sharing my doubts and frustration against Linstor -- I found my way around it. HTH -- Pierre-Philipp Braun SMTP Healt

[DRBD-user] thin volume looses sparse during replication

ep... Is there a way to make the initial replication keep being thin (or sparse, as in file-system terminology, when dealing with zeroes)? Thank you! Best regards, -- Pierre-Philipp Braun SMTP Health Campaign: enforce STARTTLS and verify MX certificates <https://neth

Re: [DRBD-user] thin volume looses sparse during replication

Check the section in DRBD user guide, "4.1.8. Skipping initial resynchronization". I think  that's what you are looking for, assuming that there's no need to preserve the data on existing volumes (i.e you start with blank LVM volumes). Thanks, that helped a lot. -- Pierr

talk about using DRBD for distributed storage

understand why DRBD v9 with the diskless feature is not competing with Ceph RBD on the emerging software distributed storage market. Maybe because some people got stuck with Linstor, just like I did few years ago. BR -- Pierre-Philipp Braun
