I really appreciate your help in this. Thank you.

hi all, can I migrate my zfs dataset from actually pool to pool on another disk but it's contain a pool with dataset from archlinux?

zfs send/restore?

be warned: do not mix encrypted datasets which you access from both linux and freebsd

No no. Actually I'm not use encrypted datasets

be warned: do not mix encrypted datasets which you access from both linux and freebsd

what do you mean by mix? is there some caveat by acessing an encrypted pool from linux and bsd? aside the zfs flags compatibility?

access (read/write) from both sides

I have been testing this since 2016 and have encountered many unreadable datasets

e.g. write data on freebsd, then on linux, then on freebsd, then update on linux from openzfs-2.1.2 to openzfs-2.1.4, then write, then try to access from freebsd: I/O error, then try to access from linux: I/O error

hm, interesting, I even had Arch Linux running with the git version of openzfs, must have been lucky so far 🤪

and FreeBSD

*makes backup*

now I am back to MX Linux again because I was a bit annoyed with Arch (Artix), AUR is nice and all for up to date stuff but it made the system unstable, crashes in applications etc.... another iteration of openzfs and still no error, but I'll keep that in mind, thanks 👍🏻

Is it normal 4.5G memory usage?

Is it normal 4.5G memory usage?

from my experience.....it depends on the application you are using and also the windows manager. if not many applications running, it will be reduced

It just xfce with slim login window manager

that is high. me 3x the #of pkgs 1/3 ram use

i have 651+ pkgs n using i3wm. at the moment with many applications running and 2 browsers opened with about 15 tabs, my ram usabe is 5.4G. Thats normal for me. it goes up n down

Before came to freebsd I was use suckless dwm. Because still not know everything in bsd or let us said I dont know how manage the process, like mount drive or packaging ... Etc. In suckless, i can reduce ram usage to 150MB to 200MB.

try this link....very useful tips from someone. pls ready the freebsd handbook too. https://vermaden.wordpress.com

They are almost the same.

Thanks 🙏, I am in Absolute Freebsd by Michael Lucas. After finishing, I will start for freebsd handbook.

And your link is helpful tho.

Thankq...ThaT guy is very helpful

Is it normal 4.5G memory usage?

I bet most of it is buffers and cache. Do you use zfs?

ZFS doesn’t use much memory unless you enable deduplication (which you should not)

Any system should excel at using all of your memory to speedup what you are doing.

ZFS doesn’t use much memory unless you enable deduplication (which you should not)

☝️This basically.

ZFS doesn’t use much memory unless you enable deduplication (which you should not)

It does from 1/3 to 1/2 IIRC if you don't set vfs.zfs.arc_max

It does from 1/3 to 1/2 IIRC if you don't set vfs.zfs.arc_max

That’s the maximum it is allowed to use, not what it actually uses all the time

OP didn't write how long the system is up and how busy it is

Uptime is 21 mins :)

zfs uses quite a lot as ARC (cache), up to 50%

even more ... standard is total RAM minus 1GB

My Arch Linux right now (XFCE, ZFS) uses 640M OS is different but OpenZFS codebase is the same Cannot log on my FreeBSD instance rn but RAM usage is low there too (webserver, 12.2)

yes, does not mean it eats your ram immediately. also dependent on the size of your storage pools

Uptime is 21 mins :)

true.dat

Hehe, define busy: Memory: 6264M Active, 108M Inact, 2948M Wired, 80M Cache, 691M Buf, 4264M Free Swap: 64G Total, 14G Used, 50G Free, 22% Inuse, 10M In, 8932K Out This is just www/firefox build, 4G free RAM is due to some processes using that much RAM recently exited freeing it to the system, otherwise whole RAM would be used for cache/tmpfs.

modern browsers are horrible

the whole web is broken

Nah, Firefox itself is fine, but having too many cores means any parallel build will vacuum all your RAM in no time.

One compiler instance can eat 2Gb easily, which is already more then Firefox is using with all my hundred tabs.

Why is freebsd not a popular operating system?

It takes more time to set up. Also driver support is not so good

Yes

Yes

Set vfs.zfs.arc_max to a minimum and see if it still consumes memory

Set vfs.zfs.arc_max to a minimum and see if it still consumes memory

too advanced. I google it and see several solution 😅

@JayOK can we skip this right now? because I want finished two books right now. I thought it will be easy solution. 😅

several of my systems have set vfs.zfs.arc_max set to 256 mb, and it works, for these slow storage systems

several of my systems have set vfs.zfs.arc_max set to 256 mb, and it works, for these slow storage systems

is it just add line in /boot/loader.conf vfs.zfs.arc_max="256MB" ?

no, you have to write it in bytes

256*1024*1024

256*1024*1024

vfs.zfs.arc_max="277872640"

like this ?

yes

and of course reboot

it is. good luck

and of course reboot

it became 1238 MiB, it is better than 4G.

@rob2g2 thanks

hi guys! i have a fbsd machine with xfce. i have wavelan-plugin installed. however when i click on a message error appeared telling me that he cant find nm-connection-editor. any ideas. thank you.

Systems, Science and FreeBSD What makes a platform suitable to both research and development? It is not simply the artifacts that are generated, but the tools that the platform brings to bear on evaluating the usefulness and quality of the research that is being undertaken. FreeBSD continues to push the boundaries of systems research through its adoption and extension of significant new technologies such as DTrace and LLVM. This talk looks at how the latest tools and techniques are being applied to systems research and how the tools enable us to find deeper insights and more clearly communicate and share our results with other researchers.

sysctl hw.acpi.lid_switch_state=S3 any way to set this permanent?

works if i put it under rc.conf?

or under loader.conf?

sysctl hw.acpi.lid_switch_state=S3 any way to set this permanent?

/etc/sysctl.conf file.

thanks

but how do i set it to go into the sddm

i mean to ask me the credentials, lockscreen and stuff

but how do i set it to go into the sddm

You must configure the sddm.

Read its manual/documentation.
