I assume this is the same issue, but renaming cache pools and cache origin volumes also results in Buffer I/O errors.

I was able to reproduce this with the older code. With the latest code, I get: ACTIVE: [root@bp-01 ~]# cp -r linux-rhel6/ /mnt & [root@bp-01 ~]# lvremove -ff vg/cachepool Flushing cache for lv. 12840 blocks must still be flushed. ... 109 blocks must still be flushed. 0 blocks must still be flushed. Logical volume "cachepool" successfully removed There are no I/O errors in the log. INACTIVE: [root@bp-01 ~]# vgchange -an vg 0 logical volume(s) in volume group "vg" now active [root@bp-01 ~]# lvremove vg/cachepool Flushing cache for lv. 0 blocks must still be flushed. Logical volume "cachepool" successfully removed This does appear fixed in the latest rpms. lvm2-2.02.111-1.el7 BUILT: Mon Sep 29 09:18:07 CDT 2014 lvm2-libs-2.02.111-1.el7 BUILT: Mon Sep 29 09:18:07 CDT 2014 lvm2-cluster-2.02.111-1.el7 BUILT: Mon Sep 29 09:18:07 CDT 2014 device-mapper-1.02.90-1.el7 BUILT: Mon Sep 29 09:18:07 CDT 2014 device-mapper-libs-1.02.90-1.el7 BUILT: Mon Sep 29 09:18:07 CDT 2014 device-mapper-event-1.02.90-1.el7 BUILT: Mon Sep 29 09:18:07 CDT 2014 device-mapper-event-libs-1.02.90-1.el7 BUILT: Mon Sep 29 09:18:07 CDT 2014 device-mapper-persistent-data-0.3.2-1.el7 BUILT: Thu Apr 3 09:58:51 CDT 2014 cmirror-2.02.111-1.el7 BUILT: Mon Sep 29 09:18:07 CDT 2014 Marking verified in the latest rpms.
