Migrate From Synology DS220J to UGREEN DX4600

导言

Synology is too expensive, and after graduate school there is little time for me to study the OOW things.

Excellent Video Resource

We’re still on the lookout for an exceptional blog or overview paper to complement our understanding of this topic. Stay tuned for updates!

Outstanding Blog or Overview Paper

The key words are “rethink”, “perspective”

总结与规划

当前占用 Occupation

1. traditional TV + movie: 4812G
2. anime related : 3610G
3. adult : 3356G

数据增长、消费和删除速度分析

控制数据高质量增长

1. 每天手动收集的精品hanime，iwara，m-Team内容，平均每天 3-5GB，总时长1h+
2. 每个季度追番。少量增长。
3. 不时的优秀电影和电视剧下载, 漫画不要再下合集了
4. 警惕下AV合集，垃圾内容占比太多了

增加消费的时间&速度

1. 白天两个饭间，和在寝室简单工作时。优先消费电影和电视剧(2倍速)。（不要追大毛和B站的低质视频了
   1. 大占用的: 天盛长歌、庆余年、
   2. 紧张的盘占用的：琅琊榜
2. 夜晚至少1h脱敏训练(iwara + av) +追番
   1. 筛选半小时低质AV，第二天删除

及时删除不适合的大内容

优秀的作品 不等于 适合我lsp的作品。

1. 不好看、看过的，不值得看第二遍的电影电视剧
2. 快速筛选AV
3. 不会删除的: iwara, hanime 手动精选的内容

后续规划与整理

Disk	后续定位	后续整理方向
Z	hanime 2D	删除和移动AV内容
X	各种的经典内容混搭
Y	新anime为主	TV电视剧处理
W	iwara内容	紧急处理TV和AV
UDisk1	漫画 + hanime
UDisk2	AV + TV + Movie	删除低质量AV
Desktop SSD1	游戏 + iwara临时目录	iwara以后下在这里
Desktop SSD2	2k 120fps视频的存放制作
Desktop Removable SSD1	备份盘(重要文档和精选作品)
Desktop Removable SSD2	3Danime	观看删除或者后续移动到UDisk1

Disk moving Or Not

Why you want to move disk

1. If I want to use N5101 to support jellyfin instead of jellyfin in windows or in soft-route.
2. jellyfin on windows need more electric charge.

You need to move the disk 2 DX4600

Supersede reason

1. not familier with UGREEN system
2. In school, no electric charge
3. we can use the step by step data moving strategy.
   1. Using lab’s UPS for DX4600 temporary security.

Config DX4600

1. Install 16GB memory bank & M2 SSD & 16TB HHD
2. Connect to the device, Initialize and upgrade firmwork
   1. stupid: must under a router have network
   2. Initialize and upgrade firmwork all in mobile phone app
3. Out of router, you should open PC app^4 in local network
   1. ssh 远程调试 for strange port ssh -p 922 [email protected]
   2. 本地账号登陆 in PC app
   3. CAN SET STATIC IP not as described in [^2]

Reason

Some similer failure happened in my Synology Assistant.

The is because the DHCP server malloc device to different IP segments even they are neighbor in real physical location [^1].

UGREEN Nas is 212.xxx , But Synology Devices in 222.195.90.2

So the dilemma can only be fixed by logging the DHCP message using tcpdump.

(tcpdump -ni any udp port 67 or 68 &> /mnt/dm-5/tcpdump.log &)
# kill to write to files
ps aux |grep tcmp
kill xxx

Using ipv6 broadcast to find

wget "http://standards-oui.ieee.org/oui.txt"
NIC=vmbr0
ping ff02::1%$NIC
ip -6 n |grep $NIC | awk '{print $5}' | tee ip6-neigh.log  #获得所有邻居的mac地址
# or just arp |grep MAC_ADRRESS

for m in $(tr -d ':' < ip6-neigh.log | grep -o '^......'); do grep -iF "$m" oui.txt; done |tee mac_vendor.log  # 对每个mac查询数据库
# tr delete colons(':') in mac address
# grep -o '^......' get the first 6 characters
# and grep -iF to search the pattern in case-insensitive way.

As yfy tested[^4], I can try to find my Synolgy device.

sh-4.4# cat oui.txt |grep -i synology
90-09-D0   (hex)                Synology Incorporated
9009D0     (base 16)            Synology Incorporated
00-11-32   (hex)                Synology Incorporated
001132     (base 16)            Synology Incorporated

Principle

App can select the MAC Address devices generated from their company using arp command.

[root@ax6s ~]$ arp
IP address       HW type     Flags       HW address            Mask     Device
222.195.90.77    0x1         0x2         18:c0:4d:b8:f8:67     *        wan
192.168.233.204  0x1         0x2         98:6e:e8:23:a0:e9     *        br-lan
192.168.233.249  0x1         0x0         00:00:00:00:00:00     *        br-lan
192.168.233.154  0x1         0x2         a8:7e:ea:35:c6:27     *        br-lan
222.195.90.254   0x1         0x2         e8:78:ee:13:cc:01     *        wan
