Package: raidtools2 Version: 1.00.3-17 Severity: critical Justification: causes serious data loss
Running raidreconf to add another disk to a RAID-5 aborts when almost being done with error message:
raid5_map_global_to_local: disk 4 block out of range: 488098 (487840) gblock = 1464296
This happens if the disks are not 100% the same size. Due to differences in disk geometry even drives of the same size have different amounts of blocks.
The array being modified with all data on it is lost.
aj that's not nice.
I'll try to fix it.
PS: it's recommended to use mdadm instead of raidtools2.
