A couple of points here: - modern kernel dumps are not full RAM dumps, they only include those pages of kernel memory which ought to be relevant to a crash. So the dump partition can be a fair bit smaller than RAM in practice. - You can add dumpon_flags="-Z" to ask the kernel to compress kernel dumps, which further reduces the space requirement. If the watchdog is triggering a panic and you see no output about a kernel dump, I suspect dumps might not be configured after all (otherwise the kernel would print a message about insufficient space to the console). What does 'dumpon -l' print on the running system? -- You are receiving this mail because: You are the assignee for the bug.
