Hello everyone, I'm currently testing dm-integrity and its use with LVM. For RAID 1,5,6 LVM should just be able to recover the RAID when integrity fails (and the block device returns a read error). However some of my systems are single-disk systems. For those, RAIDs are not possible so I was thinking if LVM has some support for single-PV setups with parity on the same PV. While this is probably a niche feature right now, I can see other projects like Stratis benefit from the integrity checks provided by dm-integrity (and dm-crypt in the future) to detect (and thanks to parity fix) bit rots. So is there any way to get a parity setup with the current state of LVM? I was thinking of a RAID-4 with one PV but the current tooling (more specifically lvcreate) doesn't let me do that.
Thanks and regards Janne _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
