Hi all!

I have decided to setup and selfhost my own private Lemmy instance.

I will be doing with docker (podman, actually).

Should I host at home or use a dedicated VPS?

Anybody selfhosting its own Lemmy?

Do you guys have any hints for me?

Hi all!

i have a nice setup with some containers (podman rootless) and bare metal services (anything i can install bare metal, goes bare metal usually).

I used Monit, in the past, to keep an eye on my services and automatically restart something that for any reason goes down. I stopped using Monit because doesnt scale well on mobile browser and it's frankly clumsy to configure.

I could go back to Monit i guess, but i am wondering if there is anything better out there to try.

A few requirements (not necessarily mandatory, but preferable):

• Open Source (ideally: true open source, not just commercial sulutions with dumbed down free verisons)
• Not limited, or focuesd, on containers (no Watchtower and similar)
• For containers, it can just support "works" or "restart"
• For containers, if it goes above the minimum "works" and "restart" must support podman
• Must support bare metal services (status, start, stop)
• Must send email or other kind of notifications (ok IM notifications, but email preferred)
• Should additionally monitor external machines (es other servers on the LAN), or generic IP addresses
• Should detect if a web service is alive but blocked
• No need for fancy GUIs or a Web GUI (it's a pro point, but not required)
• No need for data reporting, graphics and such aminities. They are a plus, but 100% not required.

What do you guys use?

Shareisland is open to registration.

Mostly Italian and multi language content.

Edit: seems broken at this time, but check on the next days as it will work sooner or later. There has been an official announcement that registrations will open soon for a brief window. No idea precisely when, i supposed they where already open at the time of the announcement.

Hi!

I used to have three raid1:

2 x 4Tb Ssd dedicated to store personal data

2 x 6Tb HDD dedicated to store "iso's", the eye patched ones.

2 x 4Tb ssd for backup.

Ext4 everywhere.

I run this setup for years, maybe even 20 years (with many different disks and sizes over time).

I decided that was time to be more efficient.

I removed the two HDD, saving quite a lot of power, and switched the four sdd to RAID5, Then put BTRFS on top of that. Please note, I am not using btrfs raid feature, but Linux mdadm software raid (which I have been using rock solid for years) with btrfs on top as if on a single drive.

I choose MD not only for my past very positive experience, but specially because I love how easy is to recover and restore from many issues.

I choose not to try zfs because I don't feel comfortable in using out of kernel drivers and I dislike how zfs seems to be RAM hungry.

What do you guys think?

I am smarting up my home with lots of ZigBee thingies and decided to add a ZigBee smart monitor to my selfhost setup.

Its a desktop box with a core i7 9th gen, 48gb ram, no monitor.

I used to have 4xSSD 4TB + 2xHDD 6TB. Three RAID1 for a total of 4+4+6=14Tbs.

Power was sitting at 50W.

I restructured my storage: 1 RAID5 with the 4 SSDs (12tb) and removed the 2 HDDs.

Power went down to 38W!

I am amazed.

In the future will run just 1 hdd for storing backups and keep it spinned down 99% of the time.

PS: the above wattage is during transcoding, so with high CPU and disk usage....

(crossposting, because i think it can be interesting here too)

I like my video collection nicely organized and omogeneous as formats, codecs and resolution.

I know there are already pleanty of solutions like Tidarr, but i find them a bit too much for my needs, and also pretty complex to use.

I wrote a simpler approach in a bash script called "Media Fixer", the URL is at the top of this post.

Feel free to check it out, play with it. I hope it can be useful for others as well as me.

It's released under the GPLv3.

Well, here my story, might it be useful to others too.

I have a home server with 6Tb RAID1 (os on dedicated nvme). I was playing with bios update and adding more RAM, and out of the blue after the last reboot my RAID was somehow shutdown unclean and needed a fix. I probably unplugged the power chord too soon while the system was shutting down containers.

Well, no biggie, I just run fsck and mount it, so there it goes: "mkfs.ext4 /dev/md0"

Then hit "y" quickly when it said "the partition contains an ext4 signature blah blah" I was in a hurry so...

Guess what? And read again that command carefully.

Too late, I hit Ctrl+c but already too late. I could recover some of the files but many where corrupted anyway.

Lucky for me, I had been able to recover 85% of everything from my backups (restic+backrest to the rescue!) Recreate the remaining 5% (mostly docker compose files located in the odd non backupped folders) and recovered the last 10% from the old 4Tb I replaced to increase space some time ago. Luckly, that was never changing old personal stuff that I would have regret losing, but didn't consider critical enough on backup.

The cold shivers I had before i checked my restic backup discovering that I didn't actually postponed backup of those additional folders...

Today I will add another layer of backup in the form of an external USB drive to store never-changing data like... My ISOs...

This is my backup strategy up to yesterday, I have backrest automating restic:

• 1 local backup of the important stuff (personal data mostly)
• 1 second copy of the important stuff on an USB drive connected to an openwrt router on the other side of home
• 1 third copy of the important stuff on a remote VPS

And since this morning I have added:

• a few git repos (pushed and backup in the important stuff) with all docker compose, keys and such (the 5%)
• an additional USB local drive where I will be backup ALL files, even that 10% which never changes and its not "important" but I would miss if I lost it.

Tools like restic and Borg and so critical that you will regret not having had them sooner.

Setup your backups like yesterday. If you didn't already, do it now.

In my server I currently have an Intel i7 9th gen CPU with integrated Intel video.

I don't use or need A.I. or LLM stuff, but we use jellyfin extensively in the family.

So far jellyfin worked always perfectly fine, but I could add (for free) an NVIDIA 2060 or a 1060. Would it be worth it?

And as power consumption, will the increase be noticeable? Should I do it or pass?

Hi!

I have setup ScanServJS which is an awesome web page that access your scanner and let you scan and download the scanned pages from your self hosted web server. I have the scanner configured via sane locally on the server and now I can scan via web from whatever device (phone, laptop, tablet, whatever) with the same consistent web interface for everyone. No need to configure drivers anywhere else.

I want to do the same with printing. On my server, the printer is already configured using CUPS, and I can print from Linux laptops via shared cups printer. But that require a setup anyway, and while I could make it work for phones and tablets, I want to avoid that

I would like to setup a nice web page, like for the scanner, where the users no matter the device they use, can upload files and print them. Without installing nor configuring anything on their devices.

Is there anything that I can self-host to this end?

Hi fellow hosters!

I do selfhost lots of stuff, starting from the classical '*Arrs all the way to SilberBullet and photos services.

I even have two ISPs at home to manage failover in case one goes down, in fact I do rely on my home services a lot specially when I am not at home.

The main server is a powerful but older laptop to which i have recently replaced the battery because of its age, but my storage is composed of two raid arrays, which are of course external jbods, and with external power supplies.

A few years ago I purchased a cheap UPS, basically this one: EPYC® TETRYS - UPS https://amzn.eu/d/iTYYNsc

Which works just fine and can sustain the two raids for long enough until any small power outage is gone.

The downside is that the battery itself degrades quickly and every one or two years top it needs to be replaced, which is not only a cost but also an inconvenience because i usually find out always the worst possible time (power outage), of course!

How do you tackle the issue in your setups?

I need to mention that I live in the countryside. Power outages are like once or twice per year, so not big deal, just annoying.

I have a home network with an internal DNS resolver. I have some subdomains (public) that maps to a real world IP address, and maps to the home server private address when inside home.

In short, i use unbound and have added some local-data entries so that when at home, those subdomains points to 192.168.x.y instead.

All works perfectly fine from Windows and from Linux PCs.

Android, instead, doesnt work.

With dynamic DHCP allocation on android, the names cannot be resolved (ping will fail...) from the android devices. With specific global DNS servers (like dns.adguard.com) of course will always resolve to the public IP.

The only solution i found is to disable DHCP for the Wifi on android and set a static IP with the 192.168.x.y as DNS server, in this case it will work.

But why? Aynbody has any hints?

It's like Android has some kind of DNS binding protection enabled by default, but i cannot find any information at all.
