This document (000020256) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15
SUSE Linux Enterprise Server 12

Situation

When attempting to run analyzevmcore on the server with a kernel core dump file, the following error is observed:

===============================================
       Support Utilities - Analyzevmcore
            Script Version: 1.34
            Script Date: 2020 04 27
===============================================

Unsupported KDUMP_SAVEDIR specified in /etc/sysconfig/kdump!
  Supported syntax:  file:///var/crash
  Current setting:   /var/crash

The /etc/sysconfig/kdump value is:
KDUMP_SAVEDIR="/var/crash"

The kdump(5) man page says the URL FORMAT accepts simple directories.

Resolution

The issue is reported to engineering. To workaround the issue, edit /etc/sysconfig/kdump and change

KDUMP_SAVEDIR="/var/crash"

to

KDUMP_SAVEDIR="file:///var/crash"

Cause

analyzevmcore does not take into account simple directories are supported.

Status

Reported to Engineering

Additional Information

In general, the URL format is protocol://specification, where protocol is one of:

file, ftp, sftp (alias is scp), ssh, nfs, cifs (alias is smb)

NOTE: analyzevmcore only supports the file protocol. Whereas the file prefix should be optional, in some releases of supportutils, analyzvmcore required it.

The file protocol format: [file://]/path
