possiblylinux127 , in tell me your experience using zfs/btrfs

Btrfs is good for small systems with 1-2 disks. ZFS is good for many disks and benefits heavily from ram. ZFS also has specially disks.

FrederikNJS ,

BTRFS is running just fine for my 8 disk home server.

possiblylinux127 ,

That is not a recommended setup. Raid5 is not stable yet.

FrederikNJS ,

I never said anything about RAID5. I’m running RAID1.

possiblylinux127 ,

For 8 disks?

FrederikNJS ,

Yep

possiblylinux127 ,

Interesting

FrederikNJS ,

Oh, I misremembered… It’s only 7 disks in BTRFS RAID1.

I have:

  • 12 TB
  • 8 TB
  • 6 TB
  • 6 TB
  • 3 TB
  • 3 TB
  • 2 TB

For a combined total of 40 TB raw storage, which in RAID1 turns into 20 TB usable.

Stick with ext3/ext4

possiblylinux127 ,

Ext4 is bad for data integrity and has slow performance. ext3 is just dated.

@hellvolution@lemmygrad.ml avatar

I’m running ext2/ext3/ext4 since 2002(?)… Never had a problem! But I’ve lost lots of data using reiser4, xfs & xfs, specially when blackout happens. If you don’t have a no-break/not using a notebook, and you have important data for yourself, I’d stick with ext4. I actually didn’t notice thaaaat much of performance boost, when using fast HDDs, SSDs & Nvme between any of these formats!

possiblylinux127 ,

Like you say, ext4 is absolutely ancient at this point. I still use it for VMs as it has low overhead and no compression but for bare metal ext4 feels old.

XFS can’t really be compared to btrfs or ZFS as it is closer to ext4. If your curious Wikipedia as a table of filesystems and the features they provide. As far as XFS’s reliability goes I can’t really say as I just use ext4, btrfs or ZFS.

bus_factor , in Thinking about switching back to Linux

I’m not sure which version of Gnome you used before, but Cinnamon is a fork of Gnome 2 and pretty popular. Looks fairly similar to Windows out of the box. Xfce is another popular choice.

spittingimage , in I made a mistake **RESOLVED**
@spittingimage@lemmy.world avatar

I did something similar. I loaded an older version of Mint off a live CD to use GPartEd to resize them. It worked like a charm, no problems.

h3ndrik , in I made a mistake **RESOLVED**

resize2fs and lvreduce? I mean if you have used LVM… It’s not easy, but doable without a reinstall. Yeah. the guides also tell people to make a backup first.

yeah, that’s been my conclusion as well. ripping off a bandaid that may break bad.

zingo , in What software is best to have in a flatpak on tumbleweed?

“Core apps” are better on baremetal for seamless system integration.

Just use flatpaks for everything else.

Sentau , in On how to fork a GNOME Core app without meaning to do so – GNOME adventures in mobile

Was this app removed from flathub¿? I wanted to try this after reading about it but can’t find it on flathub. The flathub link given on the project gitlab page also leads to 404 page not found error

milk ,

The wiki page also doesn’t exist yet so I think its probably just that they took the Evince readme and changed all the links and its not actually published yet

MyNameIsRichard , in Firewall preventing Printing/Scanning on OpenSUSE Tumbleweed
@MyNameIsRichard@lemmy.ml avatar

Is mdns allowed?

iggames OP ,

Added “mdns” service to allowed list for public zone, still get the SANE error. (Previously added 5353 UDP per another suggestion – sounds like this is the port for mDNS)

MyNameIsRichard ,
@MyNameIsRichard@lemmy.ml avatar

A quick scan through the services in Yast firewall revealed that there is a sane service too. Is that enabled?

iggames OP ,

Yes, “sane” service is already in the “Allowed” list.

lemmyvore , in Firewall preventing Printing/Scanning on OpenSUSE Tumbleweed

Are you using Avahi for the auto discovery? If so you need to open port 5353 UDP.

iggames OP ,

No change with allowing 5353 UDP through the firewall, unfortunately. But thank you for the suggestion!

lemmyvore ,

You may also need to allow multicast. Look into it a bit more.

You can also enable debugging on the firewall and see what exactly gets blocked.

iggames OP ,

Added some info to the post. Firewall is blocking 3289 UDP from my printer, so I added 3289 UDP to open ports for “home”, “public”, and “internal” zones. However, I’m still seeing filter_IN_public_REJECT entries in dmesg, so it seems the firewall is still blocking these. Is there a different way I should be telling it to allow requests on this port?

Firewall also allows mdns service (again, in “home”, “public”, and “internal” zones), but I also see entries like this:

[41951.119486] filter_IN_public_REJECT: IN=wlp0s20f0u3 OUT= MAC= SRC=192.168.1.1 DST=224.0.0.1 LEN=36 TOS=0x00 PREC=0x00 TTL=1 ID=10725 DF PROTO=2 MARK=0x3214

It sounds like 224.0.0.1 is related to mdns broadcasts, so it seems firewall is also still blocking these (despite mdns being allowed service).

Am I specifying these in the wrong place? (Per Connections - System Settings, my wifi is in Firewall zone “home”).

Flaky , in Laptop companies: which one?
@Flaky@iusearchlinux.fyi avatar

Framework and System76 are both pretty good and user-serviceable. I know System76’s customer service is particularly really good.

wwwgem OP ,
@wwwgem@lemmy.ml avatar

Looks like Framework receives a ton of support. System76 has been surprisingly almost not mentioned and not always in the best terms.
Thanks for your feedback!

rambos , in Help with Bluetooth on Pop!_OS

Im using anker soundcore bluetooth speaker on desktop PC. It was acting weird on windows, then I switched to PopOS and it became super smooth for more than a year. Turning on PC then speaker or the other way around it would always pair flawlesly. But since some update around a month ago its not always pairing automatically and sometimes I have to connect manually to get it working. Its not a big deal, but throwing it here in case someone knows a fix and even better if the same fix can help with OPs issue

Gingernate , in Help with Bluetooth on Pop!_OS

Ok you switched back to fedora, were you able to downgrade bluez? Also, is this a new popos install? Have you updated your system using “sudo apt update” and “sudo apt upgrade”? If the bluez fixed the issue on fedora I bet it will fix it on popos

may_nya , in [SOLVED] Arch efi partition error

idk mybe your drive is fucked up so you should try a new one. also did you use fdisk or the graphical one ? and did you generate a new gpt/mbr tab ?

Hiro8811 OP ,

I solved it somewhat. There’s only two entries in fstab now but for some reason the efi partition still gets automatically mounted and the grub theme dosen’t work

yianiris ,
@yianiris@kafeneio.social avatar

1 are you using systemd-boot?

2 is your efi mounted as efi or boot?

3 depending on 2, manually unmount efi and see what you have on boot, maybe you have grub.cfg in 2 places.

@Hiro8811 @may_nya

Hiro8811 OP ,
  1. I think so, it ships with arch, right?
  2. I had it mounted in more places. First on /boot then in /grub and now it’s in /efi.
  3. The grub.cfg config has always been in the same folder but I’ll check it to make sure.
yianiris ,
@yianiris@kafeneio.social avatar

When I had an /efi mount just as arch said on wiki I didn't have problems. /boot stayed with root system, so it can be booted with efi or mbr.

If you have 2+ disks and one has mbr the other is gpt you can boot from either bootloader.

You should also try limine, less headaches than grub.

@Hiro8811

Hiro8811 OP ,

I have windows with broken efi partition on another disk but that’s not important, or is it?

yianiris ,
@yianiris@kafeneio.social avatar

To turn os-prober on see /etc/default/grub -> false and install os-prober, then run grub-mkconfig -o ..

@Hiro8811

Hiro8811 OP ,

Dosen’t work. At first the partition was dirty no I managed to run chxdisk(or whatever its called) and can mount it without hassle but it still dosen’t appear in boot menu. I think there’s something wrong with grub.cfg since the theme is not displaying but I don’t know how to solve it

yianiris ,
@yianiris@kafeneio.social avatar

The theme itself is defined in grub.cfg, but it may be the case that it is stored in your root partition not in efi, so during bootloading the drive can't be read from.
So if you manually change the location of the theme directory and copy it inside efi it may work, and change the position of in grub.cfg

@Hiro8811

Hiro8811 OP ,

I was looking through commands history and I noticed something. If I’m mounting efi in /efi but I save grub-mkconfig -o to /boot/grub/grub.cfg during boot grub won’t even notice the config file since root is not mounted. Should I save changes to /efi/grub/grub.cfg instead or, /boot/grub/grub.cfg is the place it should be?

yianiris ,
@yianiris@kafeneio.social avatar

root must always be mounted if you have a system, either by booting or chroot. If you mount just efi from another system .
On my setup /efi/EFI/grub only has the grub efi binary no config, /boot and therefore /boot/grub is on /root partition

Now if you have the entire /boot in the /efi partition then it would be /efi/boot/grub/grub.cfg?

@Hiro8811

Hiro8811 OP ,

What I meant is that during boot efi partition gets mounted before root so it wouldn’t be able to get config files from root partition. But that’s not the problem, I tried regenerating grub. Most likely it’s something wrong with the theme I applied. It keeps saying that it dosent found grub and that it should be mounted either in /efi or /boot but it is mounted. I’ll try with grub-customizer.

Hiro8811 OP ,

Managed to get grub theme work so the grub is set up right. I guess I should stop being a help vampire. Anyway thanks for the help
