hi guys, i'm with a doubt when i use witemostly, how the md handle the slower drive (writemostly) for example i have 2 ssd that support 500mb/s write running raid1, i included a hdd with +- 100mb/s write with writemostly flag when i execute a dd if=/dev/zero of=./test , i get near to 200mb/s with dd, and using iostat -d 1 -k, i get +- 100mb/s there's some kind of configuration to writemostly drive? something like 'buffer size' or someting like it? -- Roberto Spadim -- 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
