Upstream commit ff05ed7afd16 Corey, test with creating a raid4 LV with raid target versions 1.[89].0 (e.g. kernel-3.10.0-515.el7) or converting to raid4 which gets rejected with "RAID module does not support RAID4.". Filed bug 1396309 for the raid10 version of this issue that was originally mentioned in bug 1385149. Marking verified. Raid 4 volume activation is prevented when using incompatible versions of raid dm target and lvm2. ============================================= Initial packages (RHEL7.2): 3.10.0-327.el7.x86_64 lvm2-2.02.130-5.el7.x86_64 # dmsetup targets|grep raid raid v1.7.0 # lvs -a -o lv_name,segtype,devices -S vg_name=vg LV Type Devices raid4 raid4 raid4_rimage_0(0),raid4_rimage_1(0),raid4_rimage_2(0),raid4_rimage_3(0) [raid4_rimage_0] linear /dev/sda(1) [raid4_rimage_1] linear /dev/sdb(1) [raid4_rimage_2] linear /dev/sdc(1) [raid4_rimage_3] linear /dev/sdd(1) [raid4_rmeta_0] linear /dev/sda(0) [raid4_rmeta_1] linear /dev/sdb(0) [raid4_rmeta_2] linear /dev/sdc(0) [raid4_rmeta_3] linear /dev/sdd(0) # vgchange -an vg BEFORE PATCH: Upgrade to 3.10.0-514.el7 and lvm2-2.02.166-1.el7 # dmsetup targets|grep raid raid v1.9.0 # pvscan --cache # pvscan PV /dev/sdi VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sdg VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sdf VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sda VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sdh VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sdc VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sdb VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sdd VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sde VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/sdj VG vg lvm2 [39.99 GiB / 39.88 GiB free] PV /dev/vda2 VG rhel_virt-369 lvm2 [7.51 GiB / 40.00 MiB free] Total: 11 [407.43 GiB] / in use: 11 [407.43 GiB] / in no VG: 0 [0 ] # lvchange -ay vg/raid4 device-mapper: reload ioctl on (253:22) failed: Invalid argument May 16 10:31:10 virt-369 kernel: device-mapper: raid: Reshaping/takeover raid sets not yet supported.
