指纹库迁移步骤：
1、检查文件系统使用情况：
root@infokistA:/infokist/var/lib/dbackup3/storaged/dedup# df -h
Filesystem Size Used Avail Use% Mounted on
udev 252G 0 252G 0% /dev
tmpfs 51G 3.5M 51G 1% /run
/dev/mapper/systemvg-rootlv 194G 18G 176G 10% /
tmpfs 252G 0 252G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 252G 0 252G 0% /sys/fs/cgroup
/dev/sdak1 461M 158M 280M 37% /boot
infokist 197T 119T 79T 61% /infokist
/dev/loop0 964M 964M 0 100% /mnt/iso
tmpfs 51G 0 51G 0% /run/user/10012、检查指纹库大小

root@infokistA:/infokist/var/lib/dbackup3/storaged/dedup/db# du -hs
25G .3、停storaged 服务
root@infokistA:/infokist/var/lib/dbackup3/storaged/dedup/db# /etc/init.d/dbackup3-storaged stop
[ ok ] Stopping dbackup3-storaged (via systemctl): dbackup3-storaged.service.4、迁移指纹库，并做软链接

root@infokistA:/var/lib/dbackup3# ll
