Why would I get a parse error on this config on a host running DRBDADM 9.31.0 but not on 9.28.0?
```auto
resource nchub {
device /dev/drbd19;
disk /dev/vg0/nchub;
meta-disk internal;
on trk-kvm-02 {
node-id 2;
}
on trk-kvm-04 {
node-id 4;
}
connection {
host trk-kvm-02 address 10.10.2.186:7286;
host trk-kvm-04 address 10.10.2.187:7287;
}
}
```
on trk-kvm-02 it parses fine and I can create the resource:
```auto
$ sudo drbdadm status nchub
nchub role:Secondary
disk:Inconsistent
trk-kvm-04 connection:Connecting
```
using 9.28.0
```auto
@trk-kvm-02: $ sudo drbdadm --version
DRBDADM_BUILDTAG=GIT-hash:\ ba2ce9037989b6141222c7901d1219cf852949f1\ build\ by\ buildd@lcy02-amd64-074\,\ 2024-05-06\ 09:10:36
DRBDADM_API_VERSION=2
DRBD_KERNEL_VERSION_CODE=0x090209
DRBD_KERNEL_VERSION=9.2.9
DRBDADM_VERSION_CODE=0x091c00
DRBDADM_VERSION=9.28.0
```
but the exact same file on trk-kvm-04 with 9.31.0-rc.1 fails with:
```auto
$ sudo drbdadm create-md nchub
drbd.d/nchub.res:6: Parse error: 'disk | device | address | meta-disk | flexible-meta-disk' expected,
but got 'node-id'
```
the only difference I can see is the version of DRBD:
```auto
@trk-kvm-04:~$ sudo drbdadm --version
DRBDADM_BUILDTAG=GIT-hash:\ 2411ff2e4241716463b4afa8530dc3c628c157ce\ build\ by\ buildd@lcy02-amd64-089\,\ 2025-03-24\ 09:51:42
DRBDADM_API_VERSION=1
DRBD_KERNEL_VERSION_CODE=0x000000
DRBDADM_VERSION_CODE=0x091f00
DRBDADM_VERSION=9.31.0-rc.1
```
I was expecting both versions to accept the same syntax.
What am I missing?

Can you verify that the DRBD 9 kernel module is actually loaded (`cat /proc/drbd`)?
`drbd-utils` checks which version of the kmod is loaded into the kernel and then uses the DRBD 8 or DRBD 9 parser accordingly. `node-id` is a DRBD 9 option but not available in DRBD 8.

Thanks for this,
Nothing is loaded at all it seems.
This is a new host and my first resource to add. I can’t get past create-md:
```auto
@trk-kvm-04:/etc/drbd.d$ sudo drbdadm create-md nchub.res
drbd.d/nchub.res:6: Parse error: 'disk | device | address | meta-disk | flexible-meta-disk' expected,
but got 'node-id'
@trk-kvm-04:/etc/drbd.d$ sudo cat /etc/drbd
cat: /etc/drbd: No such file or directory
```
Actually - it is not accurate to say a new host, it was used in the past and may have DRBD8 on there. How can I force it to use DRBD 9? I expected to see only DRBD9 after issuing:
`add-apt-repository ppa:linbit/linbit-drbd9-stack`
then updating. It did install DRBD 9, I even rebooted the host expecting to have DRBD9 across the board.
What am I missing?

I noticed that you are using a PPA and a release candidate (`rc`) version of `drbdadm`. I will speculate that there are broken dependencies that weren’t met with the upgrade/install and so your node fell back on the DRBD kmod in the mainline kernel (DRBD 8.4). I will check in with the development team about this.

This looks more like a kernel module issue than a `drbd-utils` issue. Can you please provide the output of `uname -a` and `cat /etc/os-release`?

I have a slightly different kernel (just 1 minor newer), which should not matter, and everything works as expected. I installed the kernel module via dkms from the PPA (`apt install drbd-dkms`):
```auto
root@ubuntu-jammy-23:~# drbdadm --version
DRBDADM_BUILDTAG=GIT-hash:\ 2411ff2e4241716463b4afa8530dc3c628c157ce\ build\ by\ buildd@lcy02-amd64-089\,\ 2025-03-24\ 09:51:42
DRBDADM_API_VERSION=2
DRBD_KERNEL_VERSION_CODE=0x09020d
DRBD_KERNEL_VERSION=9.2.13
DRBDADM_VERSION_CODE=0x091f00
DRBDADM_VERSION=9.31.0-rc.1
root@ubuntu-jammy-23:~# uname -a
Linux ubuntu-jammy-23 5.15.0-136-generic #147-Ubuntu SMP Sat Mar 15 15:53:30 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux
```
From what I see you don’t have a valid DRBD9 kernel module for the kernel you are running.
What I would do:
`apt install --reinstall drbd-dkms` and look for any errors. If everything looks fine, then a `modinfo -F version drbd`. If that shows a version 9, then `rmmod drbd` (just to make sure a loaded 8.4 is unloaded), `modprobe drbd`, `cat /proc/drbd` to see if the version 9 module really is loaded.
tl;tr: not an utils issue at all, for whatever reason you don’t have a valid DRBD9 kmod for your kernel (headers missing?).

Brilliant!
You nailed it and I am back up and syncing!
The reinstall went perfectly, DRBD9 installed and kernel module manually loaded.
I very much appreciate the guidance.

How to install drbd on Redhat or Ubuntu and then start it automatically at boot
All commands below are executed with root privileges.
]# echo drbd \> /etc/modules-load.d/drbd.conf
Usually, when loading manually, as mentioned above
]# modprobe drbd
How to check if the driver is loaded
]# modinfo drbd
Checking if it is loaded at the kernel level
]# lsmod | grep -i drbd
drbd 568697 0
libcrc32c 12644 2 drbd
That’s it.

I just do this:
```auto
cat /etc/systemd/system/drbd.service
[Unit]
Description=DRBD Startup Service
After=network.target
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/sbin/drbdadm up all

works for me. Or is that not a question?
