I've just added a 1.9 TB array to one of my servers (running 2.4.20, the device is an 12bay-IFT IDE-to-Fibre-RAID connected via a Qlogic 2300 HBA):
Disk /dev/sdb: 255 heads, 63 sectors, 247422 cylinders Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System /dev/sdb1 1 247422 1987417183+ 83 Linux [...] Attached scsi disk sdb at scsi2, channel 0, id 0, lun 0 SCSI device sdb: -320126976 512-byte hdwr sectors (-163904 MB) sdb: sdb1
Another array (1.2 TB) gives almost the same effect: Disk /dev/sdb: 255 heads, 63 sectors, 157450 cylinders Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System /dev/sdb1 1 157450 1264717093+ 83 Linux [...] Attached scsi disk sdb at scsi2, channel 0, id 0, lun 0 SCSI device sdb: -1765523456 512-byte hdwr sectors (195564 MB) sdb: sdb1
These issues arise when using arrays larger than around 0.5 T; nevertheless, these devices do work fine with both xfs or ext3, it's "just" a cosmetical issue. However, this negative values make one feel like Linux isn't truely capable of using up to 2 TB of disk devices and so this should be resolved. To me it seems that sd.c doesn't know how to calculate the correct values for such beasts - any ideas?
