I was hoping to grow the size of the raid10. I was following this link https://raid.wiki.kernel.org/index.php/Growing#Expanding_existing_partitionsRe-read the second sentence on the first line of that page.doh! so I can only grow raid level 1/4/5/6 ok, can you suggest how can I increase the /dir (/dev/md10) with bigger disks? I already backed up the data. does linux software raid allow disks of different sizes in raid10? I did not see much discussion of raid level 10 in that wiki page.From my understanding, there are two methods: 1) Create new RAID10, dd old RAID10 to new one, expand filesystem/lvm/whatever is on the RAID10I like this method. However, can I have raid10 with disks of multiple sizes? ( for my case 2 76G and 4 300G )

2) Don't use RAID10, use RAID1 + linear. Don't increase the size of members, only add additional pairs at the end of the linear array. 3) The one exception to 2 is that you can expand the size of the last pair, but this is somewhat tricky. I've done this successfully twice, but I doubt you really want to be using linear anyway.
