Observation¶

https://app.slack.com/client/T02863RC2AC/C02CANHLANP/thread/C02CANHLANP-1649923742.408719

s390x LPAR s390zp19 run out of disk space.

Actions taken:¶

• checked if cleanup script /usr/local/bin/cleanup-openqa-assets >/dev/null works as intended -> [DONE]
• checked why cronjob was not running -> [DONE]
  • observed multiple warnings and reports regarding dangling references to old glibc versions.
  • tried to update the system via zypper, which resulted in a crash of the machine, booting into kernel panic
• started re-installation of the machine via zhmc
• Steps to configure the LPAR:

change hostname  /etc/hostname -> s390zp19
install libvirt -> zypper in libvirt
systemctl start multipathd
systemctl enable multipathd
cio_ignore -r fa00
cio_ignore -r fc00
/usr/bin/rescan-scsi-bus.sh
zfcp_host_configure fa00 1
zfcp_host_configure fc00 1

multipath -ll to check if multipath was configured
mkdir -p /var/lib/openqa/share/factory
mkdir -p /var/lib/libvirt/images
fdisk /dev/mapper/...
n -> p -> ... -> w
mkfs.ext4 /dev/mapper/...-part1

modify /etc/fstab:
# libvirt images
/dev/mapper/36005076307ffd3b30000000000000149-part1 /var/lib/libvirt/images ext4 nobarrier,data=writeback 1 0

# openqa nfs
openqa.suse.de:/var/lib/openqa/share/factory /var/lib/openqa/share/factory nfs ro 0 0

copy cleanup script from e.g. s390zp18 /usr/local/bin/cleanup-openqa-assets
crontab -e:
0 */1 * * * /usr/local/bin/cleanup-openqa-assets >/dev/null
