It's not, it's a limitation of resizing a raid and that requiring about a billion seeks across the disk surface. Also, the hardware that's going to be hosting the drives is an HP MSA, so it's not a device where we can trivially change the software. > I did not mention ZFS until now, because I didn't want limit anyone's > thinking to filesystems. But I did have it in mind all along. That does not help with resizing the RAID, given it's a hardware RAID. But again, feel free to suggest patches, the code that's driving snapshot is all out there, afaik. -- Tollef Fog Heen UNIX is user friendly, it's just picky about who its friends are -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
