We have CENTOS 5.6 on DELL server. I create VG and LV on one SSD disk. after couple weeks I decide to delete it. I unmount file system but can not delete LV. It say "in use". I try following but still NOT work: # lvchange -an /dev/VG0-SSD910/LV01-SSD910 LV VG0-SSD910/LV01-SSD910 in use: not deactivating # kpartx -d /dev/VG0-SSD910/LV01-SSD910 # lvchange -an /dev/VG0-SSD910/LV01-SSD910 LV VG0-SSD910/LV01-SSD910 in use: not deactivating Anyone have ideal how to delete it? Thanks.
