Description Jes Sorensen 2012-04-27 13:26:25 UTC
Description of problem:
Disk/volume sizes are stored in metadata using just 32 bits. These overflow
when disk size is above 2TB. 
Volume size is calculated based on int variable giving incorrect results with
disks larger than 1TB.

Version-Release number of selected component (if applicable):
3.2.3

How reproducible:
Create a imsm volume using large (1TB+) disks

Steps to Reproduce:
1.mdadm -CR c0 -eimsm -n3 /dev/sd[bcd]
2.mdadm -CR v0 -l0 -n3 /dev/sd[bcd]
3.mdadm -E /dev/md/c0

Actual results:
Disk sizes and volume size displayed are incorrect 

Expected results:
Real disk capacity is shown, created volume occupies whole disks

Additional info:
Provided patches solve the issue
