Output from hung 'lvconvert --uncache vg/lv -vvvv'
I stupidly allowed the origin and cachepool to be created on the same PV in the earlier example. Here it is again after putting them on separate devices: [root@bp-01 ~]# !lvs lvs -a -o name,size,attr,devices vg LV LSize Attr Devices [cachepool] 5.00g Cwi---C--- cachepool_cdata(0) [cachepool_cdata] 5.00g Cwi-ao---- /dev/sdc1(4) [cachepool_cmeta] 8.00m ewi-ao---- /dev/sdc1(2) lv 500.00g Cwi-a-C--- lv_corig(0) [lv_corig] 500.00g owi-aoC--- /dev/sdb1(0) [lvol0_pmspare] 8.00m ewi------- /dev/sdc1(0) [root@bp-01 ~]# off.sh /dev/sdc1 Turning off sdc Created attachment 1204891 [details]
