From: http://linux.die.net/man/8/mdadm This value can be set with --grow for RAID level 1/4/5/6. If the array was created with a size smaller than the currently active drives, the extra space can be accessed using --grow. The size can be given as max which means to choose the largest size that fits on all current drives. ----------------------- N: Jon Hardcastle E: Jon@xxxxxxxxxxxxxxx 'Do not worry about tomorrow, for tomorrow will bring worries of its own.' *********** Please note, I am phasing out jd_hardcastle AT yahoo.com and replacing it with jon AT eHardcastle.com *********** ----------------------- -- 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
