I encounter the problem when I try to shrink one logical volume. I took the actions as following steps shows:
# unmount /home # lvreduce --size -100G /dev/vg_dev/lv_home # lvdisplay /dev/vg_dev/lv_home --- Logical volume --- LV Path /dev/vg_dev/lv_home LV Name lv_home VG Name vg_dev LV UUID QOxrP3-nS36-nZTG-yL7e-sDi0-Wl9z-LXp4pJ LV Write Access read/write LV Creation host, time , LV Status available # open 1 LV Size 197.98 GiB Current LE 50683 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:4 # e2fsck -f /dev/vg_dev/lv_home e2fsck 1.41.12 (17-May-2010) The filesystem size (according to the superblock) is 78113792 blocks The physical size of the device is 51899392 blocks Either the superblock or the partition table is likely to be corrupt! Abort<y>? # resize2fs /dev/vg_dev/lv_home resize2fs 1.41.12 (17-May-2010) Please run 'e2fsck -f /dev/vg_dev/lv_home' first.
I cannot mount the logical volume at all, can someone help me solve this problem?
