正确的lvm操作步骤 pvcreate /dev/vdb pvs vgcreate -h man vgcreate vgcreate data_vg /dev/vdb vgs man lvcreate lvcreate --size 1000G -n log_lv data_vg lvs ls /dev/mapper/ mkfs.ext4 /dev/mapper/data_vg-log_lv echo "/dev/mapper//data_vg-log_lv /data ext4 defaults 0 0" >> /etc/fstab
异常的lvm操作步骤 pvcreate /dev/vdb vgcreate logdata_vg /dev/vdb lvcreate --size 1000G -n lv_log logdata_vg parted -s /dev/mapper/logdata_vg-lv_log print parted -s /dev/vdb print parted /dev/mapper/logdata_vg-lv_log mkfs.ext4 /dev/mapper/logdata_vg-lv_logp1 mount /dev/mapper/logdata_vg-lv_logp1 /data echo "/dev/mapper/logdata_vg-lv_log /data ext4 defaults 0 0" >> /etc/fstab 由于多了parted分区操作导致每次重启后挂载目录的分区不存在
