| |
Hi, There's a new patch against 2.5.24 available at http://www.gelato.unsw.edu.au/patches/2.5.24-lbd-patch
or can be pulled from bk://gelato.unsw.edu.au:2023/
With this patch large scsi discs are detected and sized correctly; and it's possible create block devices using raid up to 16TB on 32-bit platforms, and as large as you like on 64-bit platforms.
Tested at present on i386 and ia64.
The patch: -- uses sector_t instead of int where blocks or sectors are counted (sector_t is either unsigned long or u64 depending on CONFIG_LBD) -- fixes bogus sign extensions when calculating scsi capacity -- modifies the partitioning code so that EFI GPT at least can specify partitions using 64-bit numbers. -- Fixes the loop device to allow large backing files or devices, and to fail gracefully if the backing file is too large.
-- Dr Peter Chubb peterc@gelato.unsw.edu.au You are lost in a maze of BitKeeper repositories, all almost the same.
