As of the current (3.10+) Linux kernels, is it supported to make a btrfs RAID 0 out of SSDs the root mount and boot to it? This comprises several issues:
- Does the RAID 0 with SSDs support TRIM/discard blocks? (According to docs, definitely supported for a single drive but unclear for RAID)
- Does btrfs block alignment work properly in a RAID 0?
- Will grub/grub2 be able to boot to a btrfs RAID 0? (Seems like grub2 only but would like confirmation)
- More generally, how stable and well-supported is this configuration right now? Does anyone use it?
