Hi Dave, and company,
I get this error trying to open a dump of a large system:
crash: compressed kdump: invalid nr_cpus value: 640
crash: vmcore: not a supported file format
The message is from diskdump.c:
if (sizeof(*header) + sizeof(void *) * header->nr_cpus > block_size ||
header->nr_cpus <= 0) {
error(INFO, "%s: invalid nr_cpus value: %d\n",
block_size is the page size of 4096
struct disk_dump_header looks like 464 bytes
void * is 8
So it looks like 454 is the maximum number of cpus.
464 + 454*8 -> 4096
Is this intentional?
It looks like a restriction that no one ever complained about. But there
are systems (Altix UV) with 2048 cpu's.
Is there an easy fix?
-Cliff
