What's this discrepancy due to. Does > the drive report ALL sectors, even the ones used to replace "bad" ones. Definitely does not. SCSI disks report whatever number of sectors the firmware is told to report. That's *always* less than the actual number of physical sectors since drives need a reasonable supply of "spare" sectors/tracks. > However, 2929677660 does seem to tie up quite nicely with the "end sector", > from the fdisk, so I'm assuming that everything is now correct. > > Well, apart from the fact that LVM reports a Total PE allocation of 357627 > extents, which maps to 1464840192 Blocks, according to my maths anyway, > which happens to be bigger than the "available" sectors on the disk.

I expect the LVM needs to be resized anytime the size of the underlying partitions has changed. I'll bet there wiki/HOWTO someplace that describes how to do that. grant > > Cheers, > Eddie > > > > -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
