bhyve虚拟机的磁盘空间不够了，需要扩充一下。
bhyve的管理记录：https://skywalk.blog.csdn.net/article/details/157032015
以前扩充系统盘的记录：https://skywalk.blog.csdn.net/article/details/140570088
先到bhyve虚拟机的宿主机里，找到虚拟机磁盘文件/vm_images/ub19_ub22.img ，用truncate 调整磁盘文件大小。
先上结论
扩充bhyve 虚拟Ubuntu系统的系统盘大小，普通过程就是扩充逻辑卷和扩展文件系统。
如果空间没有分配，那么就用partd扩展逻辑卷对应的分区，然后再扩充逻辑卷和扩展文件系统。
常规操作
truncate 扩充虚拟机磁盘文件大小
找到 虚拟Ubuntu系统的系统盘，在/vm_images ，文件是ub19_ub22.img
root@fb5:/vm_images # ls -la
total 12423627
drwxr-xr-x 3 root wheel 5 Feb 4 18:41 .
drwxr-xr-x 24 root wheel 29 Jan 25 16:17 ..

-rw-r–r– 1 root wheel 17179869184 Mar 4 09:23 ub19_ub22.img
停止虚拟机，调整磁盘大小：
truncate -s +10G /vm_images/ub19_ub22.img
调整完毕：
root@fb5:/vm_images # ls -la
total 12423627
drwxr-xr-x 3 root wheel 5 Feb 4 18:41 .

启动Ubuntu，现在系统里面是这样的：
skywalk@ub19:/$ df -H
Filesystem Size Used Avail Use% Mounted on
tmpfs 206M 1.1M 205M 1% /run
/dev/mapper/ubuntu–vg-ubuntu–lv 11G 11G 0 100% /

/dev/vda1 799M 6.4M 793M 1% /boot/efi
tmpfs 206M 4.1k 206M 1% /run/user/1000
扩充逻辑卷
sudo lvextend -l +100%FREE /dev/mapper/ubuntu–vg-ubuntu–lv
可以看到磁盘从10G扩充到13G
sudo lvextend -l +100%FREE /dev/mapper/ubuntu–vg-ubuntu–lv
Size of logical volume ubuntu-vg/ubuntu-lv changed from 10.00 GiB (2560 extents) to 13.50 GiB (3456 extents).
Logical volume ubuntu-vg/ubuntu-lv successfully resized.
扩展文件系统
sudo resize2fs /dev/mapper/ubuntu–vg-ubuntu–lv
扩展完毕
sudo resize2fs /dev/mapper/ubuntu–vg-ubuntu–lv
resize2fs 1.46.5 (30-Dec-2021)
Filesystem at /dev/mapper/ubuntu–vg-ubuntu–lv is mounted on /; on-line resizing required
old_desc_blocks = 2, new_desc_blocks = 2
The filesystem on /dev/mapper/ubuntu–vg-ubuntu–lv is now 3538944 (4k) blocks long.
skywalk@ub19:~/.cache$ df

但是我还有一些空间呢？ 我估计这是我以前分配给磁盘的，今天扩展上去了。
新分配的空间还没扩展。
lsblk命令查看当前磁盘和分区情况

通过vgs查看未分配空间
sudo vgs
不过这台系统，刚开始看到了母系统的空间，后来再发同样的命令，看到的就是自己的了，看，还有13.5G空间没有分配。

看错了，VFree是0，没有free空间了
lsblk看到还有空间，怎么分配出来？

多一步partd扩展
用partd把前面lsblk看到的空间扩展到vda3分区。
用partd扩展vda3分区
sudo parted /dev/vda

搞定！
空间够了，可以装ollama啦！
sudo snap install ollama
不过这个ollama版本低了，是0.15.1，抽空再去升级一下就行了。
