hi guys, i was thinking in a new device block, could anyone discuss it? the idea: a LZO block device think about a block device (/dev/sda) over it we 'mount' a block device (/dev/lzo0), something like mdadm --create /dev/lzo0 --level=lzo --device=/dev/sda what it should do? read/write compressed information we could split disks in X B per split (let's think about 32KB) user will tell us to read 320 KB we will read information on 10 splits maybe information will be compressed (50%?!) with this we read less and have more information writes will be done like ssd (NAND memory) when we need to write a information read split, uncompress, put the new information, compress and write just a idea i was seeing some benchmarks about btrfs and LZO and Gzip seens to be a good optimization on read intensive enviroment why not use it at block device level? ok it will be a problem with disk crash since many information can be lost, but user could use raid1 over it or another secure solution it's not to expand disk size, it's to make read faster (less disk use, more cpu/memory use) any ideas? i don't know about a project like this -- Roberto Spadim Spadim Technology / SPAEmpresarial -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
