Previously, it was possible to have RAID logical volumes in a clustered volume group. RAID logical volumes are not cluster capable and activating them in a cluster can cause corruption. Thus, the ability to create RAID logical volumes in a cluster has been disabled.

This can cause issues when attempting operations like image splitting on raid volumes on cluster VGs. SCENARIO - [sequentially_split_off_all_raid1_pvs] Skipping this test case since cluster raids are not supported Create a raid1 with many legs and then sequentially split off each one of the PVs taft-02: lvcreate --type raid1 -m 4 -n split_pvs_sequentially -L 300M split_image Waiting until all mirror|raid volumes become fully syncd... 0/1 mirror(s) are fully synced: ( 24.77% ) 0/1 mirror(s) are fully synced: ( 55.96% ) 0/1 mirror(s) are fully synced: ( 88.21% ) 1/1 mirror(s) are fully synced: ( 100.00% ) splitting off legs: /dev/sde1 couldn't split image Error locking on node taft-04: Failed to rename split_image-split_pvs_sequentially_rimage_4 (253:12) to split_image-split_pvs_sequentially_rimage_3 Error locking on node taft-01: Failed to rename split_image-split_pvs_sequentially_rimage_4 (253:12) to split_image-split_pvs_sequentially_rimage_3 Error locking on node taft-03: Failed to rename split_image-split_pvs_sequentially_rimage_4 (253:12) to split_image-split_pvs_sequentially_rimage_3 Error locking on node taft-02: Failed to rename split_image-split_pvs_sequentially_rimage_4 (253:12) to split_image-split_pvs_sequentially_rimage_3 Failed to resume split_image/split_pvs_sequentially after committing changes Unit test (Do not allow RAID LVs to be created in a cluster VG): [root@hayes-02 lvm2]# vgs vg VG #PV #LV #SN Attr VSize VFree vg 8 0 0 wz--nc 5.07t 5.07t [root@hayes-02 lvm2]# lvcreate --type raid1 -L 100M -n lv vg Unable to create a raid1 logical volume in a cluster. commit 9efd3fb604ae34803bb2d4c94080c57d3efdba81 Author: Jonathan Brassow <jbrassow> Date: Wed Oct 3 15:52:54 2012 -0500 RAID: Do not allow RAID LVs in a cluster volume group. It would be possible to activate a RAID LV exclusively in a cluster volume group, but for now we do not allow RAID LVs to exist in a clustered volume group at all. This has two components: 1) Do not allow RAID LVs to be created in a clustered VG 2) Do not allow changing a VG from single-machine to clustered if there are RAID LVs present. no RAID LV could be created by using lvcreate command.
