Error description
For a vg with 2 mirror copies, use mirrorvg to create the 3rd mirror copy and ctrl+C to kill the mirrorvg process in the middle of running ( while still synching the pps); LVM incorrectly removes the existing 2nd mirror copy under cleanup of mirrorvg's abnormal termination. Here is an example: 1. create a regular vg that has a lv. The lv has 2 mirror copies. mkvg -f -y testvg hdisk241 hdisk242 hdisk243 mklv testvg 400 hdisk241 mirrorvg -c 2 testvg hdisk242 2. use mirrorvg to add the 3rd mirror copy and ctrl+C to kill mirrorvg process in the middle of running. # mirrorvg -c 3 testvg hdisk243 ^Cgrep: 0652-033 Cannot open /tmp/.workdir.23461972.21233776_1/non_single21233776. Now testvg loses its original 2nd copy and is left with single copy. # lsvg -l testvg testvg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT lv00 jfs 400 400 1 closed/syncd N/A
Local fix
Problem summary
When creating a 3rd mirror with mirrorvg -c3, if the process is killed with ctl+c part way through, mirrorvg will cleanup the partial 3rd mirror, but will also remove the 2nd mirror.
Problem conclusion
Change cleanup logic to not remove the 2nd mirror, but only the partial 3rd mirror.
Temporary fix
