Hello,
i have a RHEL System with Storage Foundation as Volume Manager. In a Disk Group i have 14x146GB LUN´s from a EMC² VMAX Array. After extending the LUN´s to 757GB the Volume Manager thinks the Disk is 432GB in Size. Maybe it is a OS Problem, but maybe someone faced the same and has a Solution.
To me i looks like the System has a wierd Disk Geometry Configuration. Here the Disk with the Wrong size:
# fdisk -l /dev/sdar
Disk /dev/sdar (Sun disk label): 65437 heads, 4624 sectors, 3 cylinders
Units = cylinders of 302580688 * 512 bytes
Device Flag Start End Blocks Id System
/dev/sdar3 u 0 3 453871032 5 Whole disk
/dev/sdar8 u 0 3 453871032 f Unknown
vxdisk list -o size -ug
disk_4 757.50g
vxprint Ouput from the DG
dm bronze4 disk_4 - 432.81g - - - -
And now a Disk that was Original Created with 757GB
# fdisk -l /dev/sdip
Disk /dev/sdip (Sun disk label): 16 heads, 1516 sectors, 65491 cylinders
Units = cylinders of 24256 * 512 bytes
Device Flag Start End Blocks Id System
/dev/sdip3 u 0 65491 794274848 5 Whole disk
/dev/sdip8 u 0 65491 794274848 f Unknown
vxdisk list -o size -ug
disk_33 757.50g
vxprint output from the DG
dm SISA_BRONZE_2318_disk_33 disk_33 - 757.44g - - - -
Did someone face the Same Problem and knows a Solution?
regards,
Martin
