OKD 4.16 has Known Issues

OKD 4.16 was released simulteanously with OKD 4.17.

The purpose of the OKD 4.16 release was to provide an upgrade path to exisitng OKD <4.15 clusters.

It is not intended that clusters should remain on OKD 4.16. After completing the manual steps to take your cluster to 4.16, you should proceed immediately to the 4.17 version which is available.

Known Issues - 4.16​

  • metal3 pod crash on baremetal (#2030)
  • upgrade failed when selinux is disabled (/run will be filled up to 100%)
  • boot into centos stream coreos will fail (fsck fail)
  • upgrade fail when extra packages are installed (e.g. ipset, ipvsadm)
  • disk names has changed after boot (e.g.: /dev/sda to /dev/sdb)

upgrade failed when selinux is disabled​

Enable it

sed -i 's/SELINUX=.*/SELINUX=permissive/g' /etc/selinux/config

boot into centos stream coreos will fail (fsck fail)​

In the boot process the disk check with fsck fails, because in the upgrade from FCOS to SCOS the kernel will be downgraded from 6.x to 5.x and this results in an unknown attribute for a ext4 filesystem (orphan_file).

This attribute must be removed from the underlaying disk, but this can only be done, when the assosiated filesystem is unmounted !

A possible work-a-round is to remove it in the startup process.

If you have console access​

you can configure the grub-bootloader with this options to interup the boot process:

rd.break rd.shell

In the shell you have to run the following command for all your ext4-partitions.

In most cases this will be /dev/sda3 for /boot and /dev/sda5 for /var:

lsblk

tune2fs -O ^orphan_file /dev/sda3
tune2fs -O ^orphan_file /dev/sda5

If you have no console access​

you can configure a systemd-service like this:

cat << EOF > /etc/systemd/system/disable-orphanfile.service
[Unit]
Description=Disable Orphan-File-Feature
DefaultDependencies=no
#BindsTo=%i.device
Conflicts=shutdown.target
After=systemd-fsck-root.service local-fs-pre.target
Before=system-systemd\x2dfsck.slice
#Before=systemd-fsck@%i.service

[Service]
Type=oneshot
RemainAfterExit=no
ExecStart=tune2fs -O ^orphan_file /dev/sda3
ExecStart=tune2fs -O ^orphan_file /dev/sda5
TimeoutSec=30

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable disable-orphanfile.service

upgrade fail when extra packages are installed​

Remove this packages with e.g.:

rpm-ostree uninstall ipset ipvsadm

disk names has changed after boot​

Use lsblk to identify your boot-partition (e.g.: /dev/sda3) Edit your grub-bootloader and add the option: scsi_mod.scan=sync

mount -o remount,rw /dev/sda3 /boot
#
# Edit you boot-entry and append scsi_mod.scan=sync  to the   option - line
vi /boot/loader/entries/ostree-1.conf
    scsi_mod.scan=sync
mount -o remount,ro /dev/sda3 /boot
