Sorry, it's cpool. For now cache pool repair is unsupported. Providing better error message: https://www.redhat.com/archives/lvm-devel/2015-November/msg00137.html This bug was accidentally moved from POST to MODIFIED via an error in automation, please see mmccune with any questions Fix verified in the latest rpms. BEFORE: lvm2-2.02.130-5.el7_2.5 [root@host-006 ~]# lvconvert --repair cache_sanity/pool_cmeta Can't repair LV "pool_cmeta" of segtype linear. [root@host-006 ~]# lvconvert --repair cache_sanity/pool Internal error: pool_is_active called with non-pool LV pool. syscall 'open' failed: Device or resource busy Note: you cannot run this tool with these options on live metadata. Repair of thin metadata volume of thin pool cache_sanity/pool failed (status:1). Manual repair required! Device cache_sanity-pool_cmeta (253:4) is used by another device. Cannot deactivate thin pool metadata volume pool_cmeta. AFTER: lvm2-2.02.161-3.el7.x86_64 [root@host-078 ~]# lvconvert --repair cache_sanity/pool_cmeta Operation not permitted on striped or linear LV cache_sanity/pool_cmeta.

Description of problem: Internal error and confusing error message when running --repair on cmeta. I have a cache volume used by cache LV. Running `lvconvert --repair` on cpool's cmeta fails mentioning thin pool: Repair of thin metadata volume of thin pool vg/cpool_ck69 failed (status:1). Manual repair required! Device vg-cpool_ck69_cmeta (253:2) is used by another device. Cannot deactivate thin pool metadata volume cpool_ck69_cmeta. Also internal error is reported: Internal error: pool_is_active called with non-pool LV cpool_ck69. syscall 'open' failed: Device or resource busy Note: you cannot run this tool with these options on live metadata. Version-Release number of selected component (if applicable): lvm2-2.02.130-5.el7.x86_64 Steps to Reproduce: 1. create a cpool with cache volume 2. run: lvconvert --repair vg/cpool_cmeta Actual results: Repair of thin metadata volume of thin pool vg/cpool_ck69 failed (status:1). Manual repair required! Device vg-cpool_ck69_cmeta (253:2) is used by another device. Cannot deactivate thin pool metadata volume cpool_ck69_cmeta. Expected results: Better error messages.
