Getting disk geometry mismatch errors and "wrong checksum" messages on SAN disks
Issue
- Disk geometry mismatch errors on SAN disks when partprobe is run:
[root@redhat ~]# partprobe Warning: The disk CHS geometry (239,255,63) reported by the operating system does not match the geometry stored on the disk label (937,128,32). Warning: The disk CHS geometry (239,255,63) reported by the operating system does not match the geometry stored on the disk label (937,128,32). Warning: The disk CHS geometry (239,255,63) reported by the operating system does not match the geometry stored on the disk label (937,128,32).
- disklabel checksum error in fdisk output:
[root@redhat ~]# fdisk -l /dev/sdjs Detected sun disklabel with wrong checksum. Probably you'll have to set all the values, e.g. heads, sectors, cylinders and partitions or force a fresh label (s command in main menu)
- disk corruption is suspected
