I have a little problem with my AIX 6.1, PowerHA 6.1 LVM mirroring.
I accidentally created logical volume cpsabcd2lv with external jfs2log loglv00 in the same volume group cpsdata2vg. Then I mirrored LV cpsabcd2lv on the second LUN in VG cpsdata2vg. My journal is unmirrored and only on one LUN.
I know that I canĀ“t change external jfs2log to INLINE, but is there a smart way how to repair it/mirror it? Hdisk36 and hdisk37 are the same size and contain only VG cpsdata2vg.
What if I just add copy of the LV loglv00 to hdisk37? Will it add a copy behind the LV cpsabcd2lv or this overwrite LV cpsabcd2lv?
