Description

It's like the problems we've seen elsewhere. The -m is dominating and it's not even looking at the --type and trying to change the number of mirrors on raid10 when we only support 2. And doesn't look like a regression - this wasn't working properly before this last set of changes either, albeit hitting a different failure mode. Fixed in next release. (The contents of the error messages when you attempt something disallowed remain a bit inconsistent at times, but that level of tidy up will have to wait for RHEL 7.4.) The new message is simply: --mirrors/-m cannot be changed with raid10. Fix verified in the latest rpms. lvm2-2.02.164-3.el7 BUILT: Wed Aug 24 05:20:41 CDT 2016 lvm2-libs-2.02.164-3.el7 BUILT: Wed Aug 24 05:20:41 CDT 2016 lvm2-cluster-2.02.164-3.el7 BUILT: Wed Aug 24 05:20:41 CDT 2016 [root@host-117 ~]# lvs -a -o +devices LV VG Attr LSize Log Cpy%Sync Devices POOL test rwi-a-r--- 2.00g 100.00 POOL_rimage_0(0),POOL_rimage_1(0),POOL_rimage_2(0),POOL_rimage_3(0) [POOL_rimage_0] test iwi-aor--- 1.00g /dev/sda1(1) [POOL_rimage_1] test iwi-aor--- 1.00g /dev/sdb1(1) [POOL_rimage_2] test iwi-aor--- 1.00g /dev/sdc1(1) [POOL_rimage_3] test iwi-aor--- 1.00g /dev/sdd1(1) [POOL_rmeta_0] test ewi-aor--- 4.00m /dev/sda1(0) [POOL_rmeta_1] test ewi-aor--- 4.00m /dev/sdb1(0) [POOL_rmeta_2] test ewi-aor--- 4.00m /dev/sdc1(0) [POOL_rmeta_3] test ewi-aor--- 4.00m /dev/sdd1(0) test-POOL: 0 4194304 raid raid10 4 AAAA 4194304/4194304 idle 0 0 [root@host-117 ~]# lvconvert --type raid1 -m 1 test/POOL --mirrors/-m cannot be changed with raid10.
