Description
What were you trying to do that didn't work?
Tried enabling kdump with SSH protocol on RHCOS nodes of 4.15.0 cluster deployed on IBM Power.
The kdump crash log generation is failing with SSH protocol
How reproducible:
Always
Steps to reproduce
- Deploy OCP 4.15 cluster on Power architecture
- Create Machine config using following content:
$ cat /etc/kdump.conf path /var/crash auto_reset_crashkernel yes ssh root@<VM-IP> sshkey /var/home/core/.ssh/id_rsa core_collector makedumpfile -F -l --message-level 7 -d 31
$ cat /etc/sysconfig/kdump KDUMP_COMMANDLINE_REMOVE="hugepages hugepagesz slub_debug quiet log_buf_len swiotlb hugetlb_cma ignition.firstboot rd.multipath=default" KDUMP_COMMANDLINE_APPEND="irqpoll maxcpus=1 noirqdistrib reset_devices cgroup_disable=memory numa=off udev.children-max=2 ehea.use_mcs=0 panic=10 kvm_cma_resv_ratio=0 transparent_hugepage=never novmcoredd hugetlb_cma=0 srcutree.big_cpu_lim=0" KEXEC_ARGS="--dt-no-old-root -s" KDUMP_IMG="vmlinuz"
Expected results
kdump logs should get generated and sent back to the VM
Actual results
kdump logs are not getting generated
