-Chris Titus Tech can you help me ?
I install system and this is what i make:
mkfs.btrfs /dev/sda4
mount /dev/sda4 /mnt
btrfs subvol create /mnt/-
umount /mnt
mount -t btfs -o subvol=- /dev/sda4 /mnt/
install systme after install system i make snpashot in this way:
mount /dev/sda4 /mnt
btrfs cr sn /mnt/- /mnt/-backup
after thad i need recovery from my snapshot and delete old subvol then i try to make:
boot using -backup
mount /dev/sda4 /mnt
mv /mnt/- /mnt/-old
mv /mnt/-backup /mnt/-
boot using - and after this i try delete old:
mount /dev/sda4 /mnt
btfs su delete /mnt/-old
and i get ERROR: Could not destroy subvolume/snapshot: Directory not empty
I dont know why ?

How the bloody tea is btrfs snapshotting ability, and its vulnerability to corruption of the -common files- any better than actualy using a 15 buck commercial backuping software that can do the same shit on literally every other operating system. Hows having to switch entire partitions for their snap versions any better or any more secure than just doing backups by simple commercial software. You have way higher possibility for user failure, its also easier to delete broken or corrupted files than repairing partitions. BTRFS is like stopping a bike by putting a metal pipe in the wheel

I started using btrfs about 12 days ago. I wasn't worried about fragmentation because I'm using an SSD, BUT as it turns out, the following is written on the Btrfs Wiki page:
-Files with a lot of random writes can become heavily fragmented (10000+ extents) causing thrashing on HDDs and excessive multi-second spikes of CPU load on systems with an SSD or large amount a RAM-
Does anyone know how can I monitor the filesystem's level of fragmentation? Also: are existent snapshots an issue?

Very old vid, very newbie comment.
I guess the Linux veteran response, if any, would be -learn to swim..-. I got it and am trying.
I am stuck, after much web scouring, all roads lead back to the same mud hole. You either took it for granted or I have selective senses. That -CODE- section where the -MUST do- was emphasized.... I cannot figure out where in my install that has to happen. I have been messing around in VB trying to see what makes sense, butttttt......... -Chris

Thanks for this comprehansive guide on Btrfs! I'd like to enjoy all of it's nice features, but one thing left me a bit confused. It's clear to me that root shouldn' t be installed on the top level 5, but how about the Btrfs subvolume structure on the separate home drive? In your example home is mounted on the top level 5. Isn' t that a problem? Or should only your root files not be installed on the top level 5?

What's up with people using sudo on a localhost? Aren't you tired of pointlessly writing sudo before each command? Maybe you just like writing more useless stuff in console, dunno, if so you might set sudo to ask for a password each time, not just one in 5 minutes, this way you'll be able to write even more useless things to make working with system even more inconvenient, bc you seem to like such approach.

yeah i used archfi and it messed me up, ill have to do it again because i tried doing it retroactively and yeah... better off rebuilding the OS. I had to do other things like install grub as --removable manually becausre MSI's implementation of UEFI is perfect and doesnt have any issues whatsoever /s
so installing from that script isnt as clean as it should be lol but i love it..

Looked into btrfs but I can't use it as I like since I have a separate /home drive as well as partition (my / is on my SSD, my /home is on my HDD). So I can't take snapshots of my /home, which is what I really care about. I mean it takes what, 12 minutes to install Linux so my / is of no real consequence. My data on the other hand...

You realize your big mouth is over running your ars again with insults? Try really hard not insulting others, you screwed up using a script not others! You don't know Unix like os either the most simple thing - means root ! -home -var and no I watched your video you don't know!

I've been using BTRFS for my home partition since 2014. I use in in RAID mode with multiple drives. It has saved my data, even with a couple physical drive failures during those years. Now my old 1 TB drives have all died, and been replaced with larger drives.
