I used lvm with SSD cache few years, but time to time I have problems with loads after reboot. If forgot about reboots all work great with LVM raid + LVM cache. Cache can be configured without raid. And you can add or remove cache in any time. Docs: https://man.archlinux.org/man/lvmcache.7

Insert logs in pastebin.com and attach links and you can open ticket on git.

You can use postfix + dovecot + roundcube + spamassassin + opendkim + pigeonhole. Maximum stability. Roundcube have aliases plugin.

You can start from here: https://wiki.archlinux.org/title/Virtual_user_mail_system_with_Postfix,_Dovecot_and_Roundcube

Topic starter don’t use docker containers. He use lxc containers. LXC is virtual machines on host kernel. Case is that: He have 3 virtual machines with shared disk. In 3 VMs have 3 different applications. Applications work under different users and can’t rewrite data on shared disk. That is user permissions problem.

the idea is that: all your applications work under the same user. or at least under the same group. because this is exactly how the differentiation of rights is applied.

A good plan is to create some kind of user in all three containers and run qbittorrent, samba and the third application under it.

A bad plan is to run everything under a random user with 777 rights, but this is a really bad plan.

Create a user in all three containers and work under it. That is not hard. Run qbittorent with that user. Config will be there: /home/user/.config . Then set that user for samba. I don’t know third app , but I think you can find how change user in manual.

You can use Revolt. Literaly Discord clone. https://github.com/revoltchat

Her argument for being vocal is that her and her generation will have to live with the consequences of our fuckups the longest and hardest.

Surprise, but if you stop generate energy by oil you can’t have hard industry. It is quite difficult to cast steel without huge energy consumption. And aluminum is even more difficult. But for some reason, no one wants to ride horses and abandon airplanes. Them can stop buy industrial products. And problem will gone.

And no, strangling heavy industry in your country until it is evacuated to China is not a fight for the global environment.

It is convenient, of course, to tell what idiots everyone around is without having worked a single day in heavy industry. And in Greta’s case, without having worked a day at all, apparently. I suggest she work at the factory for a couple of years and then repeat her statements.

And it is better to live for a couple of years in a country with a less mild climate. Let’s say where it is -30 in winter. Surely she doesn’t hope that all 9 billion people will fit into the warm bosom of the Gulf Stream? Pollution from heating is also very significant. We don’t even turn off cars here in some cities because then we just won’t start them.

You really won’t see this in the USA, because few people even reach the border. After September 11, the United States is fine with eliminating threats. For example, the United States knew about this attack for 2 weeks.

UPD: I also remind you that after September 11, the United States did not limit itself to one person but beat up an entire country

Short command wasn’t work in my env. I can run only with full sockets path. May be I do something wrong.

Thanks. Not full wayland protocol support and have a bugs, but something is greater than nothing. UPD: The utilization of the Internet channel has also increased

Eh, the era when it was possible to throw the interface through an SSH session is over. Sadly. Or maybe I’m just too old. XD

In first you need understand what type of suspend you use:

Suspend to RAM (aka suspend, aka sleep) The S3 sleeping state as defined by ACPI. Works by cutting off power to most parts of the machine aside from the RAM, which is required to restore the machine’s state. Because of the large power savings, it is advisable for laptops to automatically enter this mode when the computer is running on batteries and the lid is closed (or the user is inactive for some time). Suspend to disk (aka hibernate) The S4 sleeping state as defined by ACPI. Saves the machine’s state into swap space and completely powers off the machine. When the machine is powered on, the state is restored. Until then, there is zero power consumption. Hybrid suspend (aka hybrid sleep) A hybrid of suspending and hibernating, sometimes called suspend to both. Saves the machine’s state into swap space, but does not power off the machine. Instead, it invokes the default suspend. Therefore, if the battery is not depleted, the system can resume instantly. If the battery is depleted, the system can be resumed from disk, which is much slower than resuming from RAM, but the machine’s state has not been lost.

I think you use Hybrid suspend. Hybrid suspend store memory to disk (20 seconds lag) and then lost battery for memory renew. Need you Suspend to RAM maybe? 20 Seconds lag will fixed with that.

Then check

cat /sys/power/mem_sleep

If you see

[s2idle] shallow deep

check first if your UEFI advertises some settings for it, generally under Power or Sleep state or similar wording, with options named Windows 10, Windows and Linux or S3/Modern standby support for S0ix, and Legacy, Linux, Linux S3 or S3 enabled for S3 sleep.

If you don’t see anything you can swap sleep mode to Suspend to disk. That slow but don’t use any power. Or try fix sleep status.

More information you can find here: https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate

You need to create an MX record in the DNS zone of your domain. Something like:

@ IN MX 10 my.zome.
@ IN MX 20 server1.my.zome.

You can create 1 MX record or more. 10 and 20 server priority for input mails.

Then you need to create an spf record. There are several options here. For example

@ IN TXT "v=spf1 +a +mx -all"

allows you to send emails from A domain records, then from MX domain records and prohibits from all other hosts.

Theoretically, you can only create an SPF record with A but without MX and dont create MX DNS records. Although I have not tried this configuration.

This is the minimum set after which you will get into spam, but at least the letters will reach.

You also need to make a PTR record to avoid spam folder, but this is not possible on a dynamic IP.

Show df -h from Manjaro and Arch please.

Raid: https://wiki.archlinux.org/title/RAID

Don’t forget part “email notifications”. In addition to configuring the raid, you need to understand when the disk crashed, otherwise the raid will not help.

If you share files with windows. Basic way SMB share: https://wiki.archlinux.org/title/Samba

if you want share files with linux or windows with not basic ways you have many choises. NFS for example, or sshfs if you need folder time to time, or share directory with nginx ( https://stackoverflow.com/questions/10663248/how-to-configure-nginx-to-enable-kinda-file-browser-mode ), or overkill: nextcloud server.

UPD: In general, you just need to find a linux distributive with good documentation and use this documentation for the first time. Some things are solved differently in Linux than in Windows and you just won’t know about it without reading the wiki.

interesting facts about LVM:

1. You can make a volume snapshot of the system before a major change (for example, an update).

2. You can enable caching and use HDD together with SSD cache

3. You can build raid 0,1,5 directly on LVM (you still need modules from mdraid)

4. Even without a raid, you can expand the partition beyond one disk to another or migrate the partition from disk to disk (without even disabling it)

However, all this is done from the console and I do not know if there is a GUI.

I think that in order to solve such a question, we first need to consider something else. Why, if votes are so important to you, can’t you just create a bunch of accounts and vote honestly on any server?

As soon as we are really sure that 1 person is 1 vote, and not 10, 100, 10000 or any other number, then it is already possible to build trust checks between servers. Although it seems that this has not been solved even by large social networks.

The answer to your question in general is this: store the votes by servers and then double-check the result randomly.

S returns: 50 votes for a post from server A, 30 for a post from server B, 10 for a post from server C, etc. Then you can randomly check on these servers whether the amount is correct. However, there is no way to check the voices of server S, so they either have to be thrown out or still trust the server at its word. It is possible to fully verify server S only if registration on all servers goes through a trusted intermediary.

Ok. Missunderstanding.

Why “once again”? Russia/USSR has never used nuclear weapon. The only one combat nuclear bombing in history was carried out by the United States.

So what? How are civil servants, paramilitary formations created personally by Putin, and a linear engineer connected?

If Putin’s logic is mysterious to you, I can easily explain it. If you personally took money from Putin, then obey the commands. Especially if we talk about the military, which has the largest state preferences. Pension at 35 years old. Pensions are 3 times more than standard ones. Any government support, apartments, anything else. Big profits are big risks.

Politicians literally almost all entered the government through Putin’s party. In this situation, you should not try to run over to the other side, it’s obvious.

And an ordinary engineer clearly does not fit into this logic.
