No, it doesn't I have used APC UPSes for decades, with the network management cards. They do not affect the serial port. In fact, I have one on an unRAID server right now (Smart-UPS 1000 XL) that uses the serial port and has a network card.

UnRAID cannot use the network card to communicate with the UPS (other than SNMP and you don't want to go there). Reset the network card to defaults, connect it to a switch, and check your DHCP assignments to get the IP address. Then open a browser to that IP address. As for the serial interface, check your BIOS. Set up a laptop with a serial port and a null modem cable, and see if you get terminal access. Or, as other pointed out, get a $10 USB-to-serial adapter.

The serial port on the UPS is totally unrelated to the network card in the UPS. The network interface is accessed with a web browser. The serial port connection requires that you use a proprietary APC cable. Since you have the SMART UPS, you should use a SMART cable, and select SMART as the cable type. SMART cable gets you more data... plain serial gets you the shutdown signal but not much more. You can roll-your-own cable by searching for the pinouts on the Internet.

That was for the standard version, not Pro... and you have to have Pro version if you want to handle btrfs, ReiserFS, and some others. Personal license for Pro is $200. And that doesn't even begin to approach what you have to spend for recovery hardware like a PC-3000, or even DeepSpar.

UFS Explorer handles a LOT of filesystems, not just UFS. It is a very useful application, but costs real $$$ for the pro version. I use it frequently for client data recovery.

Something is strange with the warranty lookup for that drive: https://www.hgst.com/portal/site/en/support/warranty/#step_two And yes, you can reset SMART data with the right hardware (such as a PC3000 card) in your PC. Run another short self test and see what it says for hours .... but I'd be inclined to return it ASAP regardless.

Pardon me for not googling, but do you really need a special cable for crossover? I thought all the specs after 1GB included auto mdi-x. Or is it dependent on the specific physical media, i.e. optical vs copper? The Intel X540-AT2 (copper Cat 6a) will automatically do crossover for you (auto MDI-X), so you can use a regular straight-through cable to go back-to-back without a switch.

If you only need one workstation with 10GbE performance, you can use 10GbE NICS and a crossover cable between your workstation and unRAID.

That's not a universal trait. Some 4-pins have to have 4-pain fans to be speed-adjustable, and 3-pin fans will run 100%. It's that way on my Supermicro X10SRi-F.

It is due to udev scsi naming rules. First try rebooting. If that doesn't do it, see this thread: http://lime-technology.com/forum/index.php?topic=38487.0

No. Windows doesn't do balance-rr mode bonding. Read the entire thread.

They didn't. They supplied a router that was easily hacked from the WAN side (there are plenty to choose from), and someone got into it, opened those ports, and forwarded them to IPs inside the LAN.

[quote author=Frank1940 link=topic=50466.msg484927#msg484927 Remember that these guys could also be attacking your other PC's as well. You just happened to catch their activities on your server because you looked at its system log. This cannot be overemphasized. You need to shut down those ports and any port forwarding in that router. Disable UPnP and disable access to the router's config interface by the WAN side. You can add a second router (although you may end up with double NAT, it is better than nothing) on your LAN side, just for the interim.

You only see the improvement if you have more than 1 box accessing unRAID at the same time. If you have just 1 Windows box accessing unRAID, it will only get single-NIC speed. If you have 2 Windows boxes accessing unRAID at the same time, each one can theoretically get close to full single-NIC speed.

Me too.

Yes. Put a cheap router with firewall between your LAN and the Internet. https://www.blocklist.de/en/view.html?ip=116.31.116.41&page=1

The point is not to deny a thief the use of the box, but to protect your files from being revealed. Personal data (tax returns, etc.), client data, or just your own personal pictures or videos. Even simple encryption would protect you form basic criminals or identity thieves.

Encryption doesn't have to be implemented via the USB. It can be as simple as a password you enter when starting the array.

Please consider adding nocache. Nocache is available in Ubuntu and several other distros. It allows you to prefix any command with "nocache" and that command will run with minimal impact on existing cache status. For example when preclearing a disk, running backups, dd-ing a disk to an image file, text searches across large filesystem trees, etc., that will involve a lot more data than RAM, would simply churn the cache so actual useful cache contents will get lost (such as cached directory structures).

Solved... but weird. If I changed the unmountable drive from disk4 to disk14, left disk4 unassigned, the array mounts with no problems. Change it back to disk4, and the disk was unmountable to unRAID but mounted fine manually. So I wiped out the disk config and reassigned all the drives from scratch, and it is all working now.

I was replacing a couple of old disks with new ones. I precleared and added the new ones to the array, started the array, formatted the new drives (XFS) then copied the files from the old disks to the new ones via the disk shares. Then I stopped the array to unassigned the old disks and changed the disk assignments for the new ones. When I started the array, one of the new disks shows as unmountable. So I stopped the array, and mounted it by hand and it mounts fine and all the data is accessible. Tried again to restart the array and unRAID complains it is unmountable. xfs_repair -n shows no problems and the syslog shows nothing unusual. Suggestions?

Try setting the card to RAID mode with RAW devices exposed... do this from the boot/BIOS utility. Then make sure the drives show as raw.

Not on my 6.2b23. If both are auto, and I change IP to static, DNS is disabled, but remains Auto and is NOT changed to static. I tested it several times.

The problem is trying to stop the array when files are open. If no files are open, then the drives should spin down and go to low power and cool off, without having to stop the array. If drives are being kept spinning that means software is accessing the drives, and that will prevent normal unRAID shutdown.
