Hi everyone, I want to setup a couple of drives using RAID10 with mdadm. On top of /dev/md0, I want to setup one large dmcrypt/LUKS encrypted ext4 volume. As Arch wiki reads, this seems to be possible. But what about expanding that volume later on? RAID#Format_the_RAID_Filesystem recommends calculating the stripe_width value for ext4 based on the number of data disks[0]. When adding a new disk, the number of data disks would increase by one, and expanding both the dmcrypt/LUKS and the ext4 layer should be possible - but what about the stripe width_value? Does it need to be updated? Should it be updated? Is it possible to update the stripe_width value afterwards? Encryption is a must for me, and having the space accessible in one big chunk instead of individual disks would allow more efficient usage and is therefore important for me. So it would be really nice to get some information on this. Thanks in advance! Regards, L. Rose [0]: https://wiki.archlinux.org/index.php/RAID#Example_3._RAID10.2Cfar2
