I have one SATA disk (for now, will add another later on) and a VG on it. I have created some LVs. Sometimes later, I realized that when I mount an LV (say lv_a) I see the directory structure of another LV (say lv_b). If I issue a df -k, I see a wrong size for lv_a, it is the size of lv_b. But in lvdisplay output, the size for lv_a is correct. The file systems on lv_a and lv_b is JFS. /mnt is mounted as lv_b /mnt2 is mounted as lv_a but has contents of lv_b I thought that, filesystem structure is corrupted and started to work on some filesystem level utilities, but later I see that, another filesystem pair also got the same problem. So I think it is a problem in device-mapper level, not the filesystem level. What can be the possible works to get what is wrong and how to fix ? If the corruption is at filesystem level, do you have any experience on JFS-utils ? I just want to see what was stored in lv_a, what I lost in lv_a... I am new at device-mapper, I don't have enough experience on it and I do not want to loose everything while there is something that can be recovered... Any help is appreciated. Thanks and regards.. * Suleyman Kutlu * mailto: suleyman.kutlu@gmail.com
