Hello,
Sorry, I won't answer to any of your questions (as I'm not using DRBD
for Kubernetes) but to anwser to your first question : Yes, DRBD/Linstor
is completely free and a really nice piece of software.
But as it's free, we'll have to learn most caveats (and there is) by
yourself, debug by your
t 3MB/s.
What did I miss ?

Hello,
We're using ZFSThin as backend for our Linstor cluster. Nothing fancy.
I'm trying to set up a backup with ZFS snapshots and zfs send/receive.
First : is this a bad idea ? I know DRBD integrate his own snapshot
system (LVM only ?) but it can't be exported to a non-DRBD system as-is
AFAIK.
tch ?
I can't even find any changelog of Proxmox's Storage API changes from V1
to V2.
Best regards,
Julien Escario
P.S. : we're getting a ton of mail at each backup task.

Hello,

We're experiencing a really strange situation.
We often play with :
drbdmanage peer-device-options --resource --c-max-rate

Hello,
I'm trying to benchmark *correctly* my lab setup.
Pretty simple : 2 proxmox nodes setup, protocol C, ZFS RAID1 HDDs backend with
mirror log and cache on SSDs.
DRBD9, 10Gbps Ethernet network, tuned latency by reading a lot of papers on
this.
What I'm trying : run fio with below parameters
as far as I understand, 'detach' behavior should be the default no ?
My tought is that DRBD wasn't notified or didn't detect the blocked IOs on the
backend. Perhaps a specific bahevior of ZFS.
More tests to come.

This one is in secondary state (VM not running) so I could unassign/assign this

But if the ressource is already in primary state, any way to ask for a local

Using /proc/drbd doesn't sounds like a good idea : with drbd9, there's
nothing but version in there.
Perhaps should you use drbdadm and other command line tools ?

I'm really surprised by your high percentage of metadata (87,26%).
Did you do some snapshots ? It shoud be displayed by the lvs command but perhaps
some are still pending deletion or something like that ?

Hello,
So to continue with my experiments with drbdmanage and thinlv plugin :
drbdmanage 0.91 (same thing seems to happen with 0.50).
storage-plugin = drbdmanage.storage.lvm_thinlv.LvmThinLv
I create a VM with proxmox, 10 GB disk.
Right after, I got this free pool space with drbdmanage list-node

Seems I found a anwser : I was using drbdmanage 0.91 with a thin lv but this
version is using drbdmanage.storage.lvm.Lvm as default plugin.
I'm now wondering how I can change the default plugin BEFORE initializing the
nodes.

Hello,
Today, I've been stuck in creation a new volumes (with proxmox) on a 2 nodes
cluster because it reports "Not enough free space".
I checked a few settings on the machines :

Hello,
We're extensively trying drbdmanage. We're still using v0.5 but considering
trying 0.9 soon.
Just a quick question about multi-tiering : is it possible to manage 2 different
pools (one with HDD and SSD) with drbdmanage ? It's mainly about having 2
different LVM vgs as backend devices and be
Hello,
I'm currently trying some setups with DRBD9.
Today, I simulated a network failure between two nodes in protocol A with two
ressources created using DRBDmanage 0.5.
For this, I disabled and re-enabled a switch port on NodeB.
Both ressources were sync and only NodeA was primary. NodeB was s
tests by moving back the VM to node1 and with more
log activated.
Thanks for your reading and help,

I asked for the same thing (without SSD) a few weeks ago.
Someone answered me that these preformances are perfectly normal is dual master

Seems to be due to the network latency (first server I/O + network latency +
second server I/O + network latency (ACK))

Do you have any clue about what is giving me this 3.5 factor ?
What other information can I give you ?
