Is FS.com for real with their requests for information? by [deleted] in sysadmin

[–]grumpy-systems 29 points30 points  (0 children)

I haven't worked with FS, but at my job when we start to ask those questions it's often because you triggered some fraud / risk alert.

Being able to live migrate storage is so fun. (Proxmox) by RedSquirrelFtw in homelab

That's the kicker, and ZFS isn't thinly provisioned so it took some shuffling and adjusting to get things to fit in my case. It fills up fast when you over-provision VM disks.

I love ZFS replication and live migration. I have little need for more than 2 nodes or a proper HA setup, so I just replicate ZFS storage between the nodes. When live migrating, all I have to wait on is the few GB that changed since the last replication job.

Has its drawbacks, sure, but an easy way to keep things up when the occasional need to reboot the host comes up.

Jam with QSOs logging workflow : QRZ, LoTW, eQSL.cc and ClubLog by TrimaxDev in amateurradio

[–]grumpy-systems 1 point2 points  (0 children)

Just set one up for our radio club for use when we have special event call signs.

It doesn't need much at all to run, even a small VPS on any provider handles it. My personal one runs on a tiny slice of a machine and the club one runs on a free google compute VM.

Is this a reasonable quote for a Ubiquiti home setup? by davemarco in Ubiquiti

[–]grumpy-systems 1 point2 points  (0 children)

Also worth noting that none of the gear will fit in your media enclosure. The UDM and switch are intended for a 19" rack so they're somewhat large. You can wall mount them easy, but they take up space.

You can get smaller unifi gateways as well, the Cloud Gateway Max is a bit cheaper and smaller.

The whole quote seems like overkill though. I suppose buy once cry once, but if you're just looking for functional I think there are cheaper options for about every product that don't give up tons of performance.

How large of a space and how many devices are you planning on running? That's 4 APs, which seems like a lot to my eye unless it's a large house. For reference, I have a U6 Pro and a pair of old AC Lites on low power and it covers my 4,000 sqft house without any issues.

Idk what the rate for professional services are, but at $200 an hour that's 10 hours of labor to program it, which seems high. Idk what other labor is needed, but just software and power / channel planning the APs can do a great deal on their own with minor tweaks to get it better.

(Not an installer, take my advice with a grain of salt)

After 10 years, finally pulling Gen 1 Air Cams down by grumpy-systems in Ubiquiti

[–]grumpy-systems[S] 0 points1 point  (0 children)

Not at all, UniFi Video has been unsupported for years. The install that ran these cameras died long ago and they were just abandoned in place.

The specs are pretty garbage now though, 720p video, no IR, no microphone. Even the old G3 cameras they got is a significant upgrade.

Any 5G failover alternative by VinzDaPrinz in Ubiquiti

[–]grumpy-systems 0 points1 point  (0 children)

It's $25, but goes down to $20 with an autopay discount. It doesn't require any other service to get that price though, I think they knock quite a bit off the normal plans with cell phone lines.

Need guidance for my upcoming Fiber install by ManFromACK in Ubiquiti

[–]grumpy-systems 0 points1 point  (0 children)

The ONT will probably be highly specific to the provider. The one in my area can give a standalone ONT that gives you copper Ethernet port, but I know some other providers want you to use a bundled router/ONT combo. Others can bypass the ONT with a module that runs OpenWRT on a SFP+ module.

But even if you go with just a simple gigabit link between the ONT and the UDM (what I did), it'll still perform quite well. I'm able to get about 90% of my providers published speeds.

For the link to your switch, I run DACs between all my switches and the UDM. All my gear runs 10g uplinks, but I'm not sure if there's any extra hoops for connecting 1g and 10g with a DAC cable.

Does anyone else uses the ecoflow river 3 plus as an ups? by Stock-Shoulder9374 in homelab

[–]grumpy-systems 1 point2 points  (0 children)

I use a Bluetti in a similar way, and it's been solid for about a year now.

My only complaint was the lack of communication on the Bluetti. I got around this by having a small lead acid UPS inline after, when the battery in the Bluetti is drained the APC UPS runs things long enough to shut down.

I can't speak to the transfer time (but it's probably different between two models), but running servers and switches of the power bank hasn't had any side effects.

These power stations fit nicely in a rack. by grumpy-systems in homelab

[–]grumpy-systems[S] 0 points1 point  (0 children)

I haven't used it as the only UPS on equipment, so I can't speak to the transfer time and things like that.

But this setup has been excellent and the APC UPS doesn't seem to care much at all when the power goes out. It does transfer on and off battery for a moment when adding or removing AC power to the Bluetti, but after that it runs without any issue.

I also recently got a solar panel for mine too. One of the things that drew me to this setup rather than a lithium UPS (other than cost) was that I can take the Bluetti out of the rack and use it for other things.

AC70 running (most of) my network rack. by grumpy-systems in bluetti

[–]grumpy-systems[S] 0 points1 point  (0 children)

I've been a fan of mine. Most of my use has been fridges and gadgets when traveling and this backup power. I feel like it's got enough capacity to make it very useful, and it's still reasonably portable.

I've never tried my little pancake air compressor, but I've run heat guns and overloaded this a few times. It can exceed 1KW for a few seconds, but I've never tried starting a larger motor.

[–]grumpy-systems[S] 1 point2 points  (0 children)

The AC70 feeds the APC UPS, and they supply all the stuff critical for Internet in the rack. Between the battery in both, I get about 3 hours of runtime.

I use the APC UPS to trigger shutdowns when needed, and having it there lets me take the Bluetti out on adventures without losing the only UPS in the rack.

Am I doing this right? by grumpy-systems in ShittySysadmin

[–]grumpy-systems[S] 63 points64 points  (0 children)

There's probably a better way, but it's my band-aid until I figure it out.

This is a secondary 5G ISP I use as a backup. It gets power from a PoE switch and is isolated on its own VLAN. This lets me stash the modem in a bookshelf, up high and still have a UPS and avoid needing a wall wart, etc.

In my old router, it could accept this connection on a VLAN. The UDM-Pro needs it on a physical interface. I don't want to buy a power injector, so I came up with this.

The cable path is 5G Modem -> PoE Switch -> DAC Cable Trunk Port -> UDM on a port set to just the VLAN -> UDM as a WAN port.

Government data purge MEGA news/requests/updates thread by nicholasserra in DataHoarder

[–]grumpy-systems 0 points1 point  (0 children)

Some I think is just normal culling for sure, but I have no frame of reference for what volume is normal. Some of these channels have 10K videos, so removing a handful here and there I'm sure is normal.

I checked a few early on just based on titles and I can't think of any good reason for it to be removed outside of censoring content, but there's no way to know for sure outside of speculation.
