Snapshots of raid with integrity are not supported. Hi Corey, I verified this works, tried multiple snapshots, with or without -c, I just cannot reproduce this. corigin? What is the origin LV? Can you post more details, please? I checked the code and this only happens when creating snapshot of cached raid+integrity volume, and is expected behavior Marking Verified:Tested based on initial regression tests of snapshots of raid1 and raid10 + integrity origin volumes. *NOTE* no cache or writecache + raid integrity was tested with snapshots, due to that stack not yet being turned on. kernel-5.14.0-322.el9 BUILT: Fri Jun 2 10:00:53 AM CEST 2023 lvm2-2.03.21-2.el9 BUILT: Thu May 25 12:03:04 AM CEST 2023 lvm2-libs-2.03.21-2.el9 BUILT: Thu May 25 12:03:04 AM CEST 2023 |
