在VMware下安装了一个fnOS试用，系统盘给了20G，数据盘给了20G，Docker等使用没有问题。
使用相册时发现需要大于20G才能使用AI相册，遂关机在VMware下扩容数据盘从20G为40G。
重新开机后发现磁盘已经识别了，但是在fnOS内没有扩容的选项，查询了一下官网也没有相关的信息，使用fnOS网页的用户可以SSH登陆到系统，于是动手自己扩容。
用户名和密码都是网页上登陆的用户名和密码！
过程记录如下：
-
检查原有的文件系统空间
root@fnOS:/home/fnadmin# df -Th
Filesystem Type Size Used Avail Use% Mounted on
udev devtmpfs 1.9G 0 1.9G 0% /dev
tmpfs tmpfs 390M 7.7M 383M 2% /run

tmpfs tmpfs 2.0G 1.4M 2.0G 1% /dev/shm
tmpfs tmpfs 5.0M 0 5.0M 0% /run/lock
trimafs trimafs 20G 494M 19G 3% /fs
/dev/mapper/trim_e4239c90_3a1d_4c43_ba7a_b36971db3280-0 btrfs 20G 494M 19G 3% /vol1
tmpfs tmpfs 390M 0 390M 0% /run/user/1000

确认数据盘的大小为40GiB

执行命令扩容Raid
root@fnOS:/vol1# sudo mdadm --grow /dev/md127 --size=max
mdadm: component size of /dev/md127 unchanged at 41924591K
执行完了之后确认Raid的状态
root@fnOS:/vol1# mdadm --detail /dev/md127
/dev/md127:

扩容Raid之后，扩容LVM
root@fnOS:/vol1# pvresize /dev/md127
Physical volume "/dev/md127" changed
1 physical volume(s) resized or updated / 0 physical volume(s) not resized
root@fnOS:/vol1# vgs

root@fnOS:/vol1# lvextend -l +100%FREE /dev/mapper/trim_e4239c90_3a1d_4c43_ba7a_b36971db3280-0

Logical volume trim_e4239c90_3a1d_4c43_ba7a_b36971db3280/0 successfully resized.
此时扩容LVM后，按 df -Th是无法显示已经扩容的，还需要扩容文件系统
root@fnOS:/vol1# sudo btrfs filesystem resize max /vol1
Resize device id 1 (/dev/mapper/trim_e4239c90_3a1d_4c43_ba7a_b36971db3280-0) from 19.98GiB to max

至此，扩容完毕。 |
