to parse the LVM information on each LUN, found that there are three sets of LVM, of which 45G of LVM divided into a lv, which stores the OA server-side data, 190G of LVM divided into a lv, which stored temporary backup data. The remaining 4 LUNs constitute a 2.1T or so of LVM, and only one LV, which contains the Oracle database files. Write a program that interprets LVM and try to interpret the LV volumes in each set of LVM, but find that the interpreter has an error.7. Repairing LVM Logical V
