kiranchavala opened a new issue, #14180:
URL: https://github.com/apache/cloudstack/issues/14180
### problem
create-kubernetes-binaries-iso.sh builds the ISO without setting a volume ID
on EL8 based os
### versions
ACS 4.20.X
ACS 4.22.X
ACS 4.23
Management server : Oracle 8 , rocky 8
### The steps to reproduce the bug
1. ISO tooling — genisoimage does not exist on EL8; xorriso provides mkisofs
```
sudo dnf install -y xorriso curl wget
```
2. containerd (for ctr) — static tarball avoids the docker-ce repo and
podman conflicts
```
VER=1.7.24
curl -fsSL
"https://github.com/containerd/containerd/releases/download/v${VER}/containerd-${VER}-linux-amd64.tar.gz";
\
| sudo tar -C /usr/local -xz
curl -fsSL -o /tmp/runc
https://github.com/opencontainers/runc/releases/download/v1.2.3/runc.amd64
sudo install -m 755 /tmp/runc /usr/local/sbin/runc
curl -fsSL
https://raw.githubusercontent.com/containerd/containerd/main/containerd.service
\
| sudo tee /etc/systemd/system/containerd.service >/dev/null
sudo systemctl daemon-reload && sudo systemctl enable --now containerd
sudo ln -sf /usr/local/bin/ctr /usr/bin/ctr # sudo secure_path excludes
/usr/local/bin
```
3. Verify
```
mkisofs --version && sudo ctr --version && wget --version | head -1 && curl
--version | head -1
```
4. Execute the script
```
./create-kubernetes-binaries-iso.sh /var/www/html 1.37.0 1.9.1 1.37.0
https://raw.githubusercontent.com/projectcalico/calico/v3.32.2/manifests/calico.yaml
0.45.0 setup-v1.37.0 amd64 3.7.0
```
5. Verify the generated iso volume label
```
[root@ref-trl-12298-k-Mr8-suresh-anaparti-mgmt1 util]# blkid
/var/www/html/setup-v1.37.0-x86_64.iso
/var/www/html/setup-v1.37.0-x86_64.iso: BLOCK_SIZE="2048"
UUID="2026-09-16-08-13-12-00" LABEL="ISOIMAGE" TYPE="iso9660"
```
6. If the iso is used in cloudstack , the iso doesn't get mounted
7. Change the script
```
sed -i 's|^mkisofs -o |mkisofs -V CDROM -o |'
create-kubernetes-binaries-iso.sh
```
8. Run the script again and check the volume label
```
./create-kubernetes-binaries-iso.sh /var/www/html 1.37.0 1.9.1 1.37.0
https://raw.githubusercontent.com/projectcalico/calico/v3.32.2/manifests/calico.yaml
0.45.0 setup-v1.37.0 amd64 3.7.0
blkid /var/www/html/setup-v1.37.0-x86_64.iso
/var/www/html/setup-v1.37.0-x86_64.iso: BLOCK_SIZE="2048"
UUID="2026-09-16-08-34-56-00" LABEL="CDROM" TYPE="iso9660"
```
Issue is not present with ubuntu based os
```
┌──────────────────────┬───────────────┬───────────────────┐
│ │ Default volid │ With -V CDROM │
├──────────────────────┼───────────────┼───────────────────┤
│ Ubuntu (genisoimage) │ CDROM │ CDROM — unchanged │
├──────────────────────┼───────────────┼───────────────────┤
│ OL8 (xorriso compat) │ ISOIMAGE │ CDROM — fixed │
└──────────────────────┴───────────────┴───────────────────┘
```
### What to do about it?
Make the following modification to the create-kubernetes-binaries-iso.sh
sed -i 's|^mkisofs -o |mkisofs -V CDROM -o |'
create-kubernetes-binaries-iso.sh
