If you'd been running mdadm I'd have been able to help ... my setup is |
| 19 |
ext4 over lvm over md-raid over dm-integrity over hardware... |

But you've made no mention of lvgrow or whatever it's called. Not using |
| 22 |
lv-raid, I don't know whether you put ext straight on top of the raid, |
| 23 |
or do you need to grow the lv volume after you've grown the raid? I know |
| 24 |
I'd have to grow the volume. |
