My understanding is that you currently cannot expand raid10. but there are things in the works. Expansion of raid10,far was not on the list from neil, raid10,near was. But it should be fairly easy to expand raid10,far. You can just treat one of the copies as your refence data, and copy that data to the other raid0-like parts of the array. I wonder if Neil thinks he could leave that as an exersize for me to implement... I would like to be able to combine it with a reformat to a more robust layout of raid10,far that in some cases can s= urvive more than one disk failure. best regards keld > 2011/4/13 Mathias Bur=E9n : > > On 13 April 2011 05:28, Roberto Spadim wrot= e: > >> hi guys, today i have 2 disks raid10 far, with 2tb each disk/array > >> i want to expand it to 4 disks raid10 far, with 2tb each disk and = 4tb array > >> in other words, i will put more 2 disks of 2tb and i want more 2tb= of space > >> > >> could i do this with raid10 far layout? i?m using ext4 at filesyst= em > >> how could i expand ext4 filesystem? > >> > >> -- > >> Roberto Spadim > >> Spadim Technology / SPAEmpresarial > >> -- > >> To unsubscribe from this list: send the line "unsubscribe linux-ra= id" in > >> the body of a message to majordomo@vger.kernel.org > >> More majordomo info at =A0http://vger.kernel.org/majordomo-info.ht= ml > >> > > > > No, you cannot expand RAID0. > > > > // M > > -- > > To unsubscribe from this list: send the line "unsubscribe linux-rai= d" in > > the body of a message to majordomo@vger.kernel.org > > More majordomo info at =A0http://vger.kernel.org/majordomo-info.htm= l > > >=20 >=20 >=20 > --=20 > Roberto Spadim > Spadim Technology / SPAEmpresarial > -- > To unsubscribe from this list: send the line "unsubscribe linux-raid"= in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
