Won't, as backplane have both SATA and Molex power socket, you may loop them each other to ensure power draw share well to PSU power port. I means connect all SATA and Molex to 450w PSU.

450w PSU defintely enough, the remain problem are could you well connect 9 disk from 2 peripheral power port ( 450w ) instead 3 peripheral port ( 750w ).

A straightforward way was replace the compute unit, but you may save 100w - 150w endup. Would you willing spent that cost which hard to overcome the electricity bill ? PS : Recently, I buy Minisforum N5Air, but I am not using it as NAS, I detach the compute unit to replace my main Windows PC ( Intel 9600K ), it run faster and draw half power. It equip 10G and 5G ethernet, Oculink and PCIe slot. May be one day, it will return back be NAS and replace my X299 unraid build and connect 28 disks.

This seems a good idea, most people will simple recreate the pool and copy back data, appreciate for those script.

Then no br2.11 and replace with eth2.11

Did you try disable bridge, I upgrade to 7.3.1 with macvlan and not enable host access. All IOT device haven't problem to connect their vlan eth0.xx to docker.

Both capture ( text & pic ) show have 10000baseT and both negotiation at 10000Mb/s 100baseT/Half 100baseT/Full 1000baseT/Full 10000baseT/Full 2500baseT/Full 5000baseT/Full

Switching power supply usually are common AC earth and the DC ground. But P3 Tiny use external power supply, this type PS may not in same condition. SATA/SAS are differential signal, there are argument should ground for both-end ..... below post have point out a good example, will you ground all equipment if they are connect with ethernet cable ? But I would say ethernet case have some different, because there are a small transformer inside the ethernet port. https://www.edaboard.com/threads/differential-signaling-and-ground-referencing.307250/ BTW, personally I will add extra ground wire to both end's DC ground.

This is mini PC, maximum allow two M2 only. Old config are 256GB for boot pool with 64GB boot partition, remaining 174GB use for backup. Other 2TB standalone. But due to want dual device boot pool, so combine them ...... now only have one boot partition and one data partition (as below). What means expand ? Replace the 256GB to bigger one ? Thanks

Yes, success migtate to TPM, but I haven't expect so much trouble. I read different post before starting. I also change boot pool to dual device with 256GB and 2TB. Config to 64GB boot partition and the remaining in single mode btrfs fs share, did @JorgeB have any advice if only base on config setting. Tks ( No more any storage device in system )

Continue on below post After reboot, same error show again, but this time have a new option "Recover License Key" Finally, "recovery key" solve all problem, but play safe, I further reboot one more time to confirm. The registered date also change !!!

Just try to migrate to TPM, I got same error. But do one more step click "Manage License", let unraid.net have update license info. then error gone and success go to next step "Move to TPM" But click Move to TPM, then a big trouble happen, system stop immediately due to key problem, after input the key URL, then "missing key file" error also gone. But "Start" button still dim ..... so I must reboot.

I use same switch, I insert one 10G and one 2.5G converter to it, both work well for year, those are new gen chips solution and running cool ( feeling won't over 50c, 2.5G one just slightly warm ) BTW, all info. are dead hard, it won't change and meaningless. SFP may not support different speed rate, as result WOL won't work if not support 10/100 rate, You need test yourself. Agree.

NIC plugin which PCIe slot ？Only Most left are PCIe 3.0, other are 2.0 And such age platform may not handle 10g network environment.

All are depends on system design, there are no correct or wrong. You can design continue balancing also fine. The key point are when balancing start, how much power will waste, that's why you will found balancing start in above conditions for old type balancer. Balance current are depends on cell voltage different and the max current of the balancer support, unless you have boost circuit to speed up that process. In fact, charging different battery are dealing on current / voltage, that's not proper comparison.

I also use Mikrotik SWOS, no problem for multiple tag vlan per port as usual.

Although I wouldn't keep mon so much state of Unraid, but this plugin really cool.

Pls check Windows firewall or any antivirus utility cause problem.

Mention again, if phone can access Pihole, but Windows can't access then it suppose it is physical network issue. During test, I found docker.cfg won't show expected parameter even I clearup docker.cfg, so pls ignore docker.cfg. when I check my docker.cfg, it fill with previous dirty data. Even cleanup, it still wrongly show custom_networks was br1 ANYWAY, does GUI show br0 in use actually ?

If orher physical device (phone) can access Pihole, then no reason oher physical device can't access as all in same subnet 192.168.1.X. Does Windows setting in dhcp or static ？You setup Unraid in subnet in /24 255.255.255.0, does same netmak also match in Windows ？pls check in Windows by typing “ipconfig". Are you use one router only ？Windows and Unraid are connect in same router or switch ？ I can't reproduce this, and now this shouldn't the cause, pls forget in this moment. EDIT : Are you already tick br0 and bond0 when start docker service ？I am not at home, I would screen capture for better understanding. For Unraid can't ping pihole is normal because both in same host subnet. If you want overcome this, pls enable ”host access" in docker setting.

Problem on docker network setting, there shouldn't only have wlan0 appear on docker.cfg, where br0, bond0 ? Pls review docker network setting in docker config, try DOCKER_USER_NETWORKS="remove" and setting the ip, subnet, gateway ..... etc DOCKER_CUSTOM_NETWORKS="wlan0 " DOCKER_USER_NETWORKS="preserve"

Two more troubleshoot you should perform Check does expander detect on 9211, they are connect through 8087-8643 cable. Connect 9211 directly to backplane to confirm both are work.

Use USB to connect disk not recommend. But I also use USB enclosure to expend 5 more disk for ~1yrs. The setup are 8bay QNAP NAS J1800 with 5 bay enclosure. For your question, the best solution was use qnap NAS and runing Unraid, in general you can't DIY and build something solid then those NAS. For UPS, if total power less then 150w, then recommend use DC UPS instead traditionally AC UPS. DC UPS crazy cheap and smaller at all.

I also wish rsync could change this behaviour too. But finally negative and I can't found a way to overcome this. Thanks.

Below are the post for much detail for rsync create empty folder issue .... Of course you can writing script to avoid, but this too complicated. https://forums.unraid.net/topic/133960-how-to-deal-with-rsync-creating-all-empty-folders-first-and-causing-disks-to-run-out-of-space/
