In my latest blog post, I tried out #btrfs on a #RaspberryPi . I also discuss #MicroSD longevity and #ZFS a bit. https://changelog.complete.org/archives/10852-btrfs-on-a-raspberry-pi
2/n strangely enough, running #Filelight as root, scanning "/" results in only ~16GB used!
THIS DOESN'T MAKE ANY SENSE! 
"df -sh /*" reports /usr + /var = 21GB! How d'fuq can it be 99% allocated?! (the other stuff is in the negligibly MEGAbyte range)
Which memo did i miss?
No, i've got 64GB of RAM - i'm not using swap.
EDIT: "discard" IS active in crypttab/fstab - that fancy SSD TRIM / fstrim stuff
If you're one of those idiots who partitioned their #Manjaro / #Linux wrong enough, you suck at least as hard as i! 
I might be able to resize / move my partitions around. #KDEPartitionManager / #PartedMagic / #Gparted.
I'd have to shrink my #btrfs SteamLibrary, which doesn't support shrinking - NAS backup+restore via 10GbE.
but you get to pass-through USB sticks to test VMs 
..pretty neat ..you can plug the stick into other machines, and just boot it
computerkram
Living with the peace of mind of being able to roll your system back in time or simply recover a previous version of something you deleted or changed, but that didn't quite work for you, is one of the best things that can exist.
All of that, without using additional space on your disk thanks to COW.

Published a blog post on documenting my steps in installing #Debian with #Btrfs and encryption https://ravidwivedi.in/posts/installing-debian-with-btrfs-and-encryption/ .
@willbush Thanks very much for this info. Indeed in the end one errs on the side of persisting even the stuff one might ideally want to purge on reboot. I am planning using a #nixos #flake arrangement with some #btrfs and #impermanence maintenance scripts but that makes it a bit of a babysitting process. I try to expose all error messages & not ignore them so my flake system is going to be a babysitting process anyway & more checks do not change the basic maintenance routine required. Will see.
Meet #container‑snap; it turns OCI images into bootable #Btrfs snapshots for seamless, transactional OS updates. Say goodbye to halfway installs and hello to safe rollbacks!

This morning I took some time to jot down how I temporarily lost all the mail on my family's mail server last week, how I recovered, and what I've done to minimize the impact of similar events in the future.
Some of this was my fault, but the bigger TLDR is that IMO Cyrus imapd is a big pain in the ass, I should probably switch to a different IMAP server, but I don't have time to deal with that right now.

Ich wünschte wirklich, #ZFS würde endlich unter GPL gestellt werden.
Im Vergleich zu #BTRFS ist das doch sehr viel angenehmer zu handeln.
Aber - ich vermute, man muss sehr viel Halluzinogene zu sich nehmen, um erfolgreich glauben zu können, dass #Oracle hier was Gutes tun könnte, oder?
(Anlass war eine im Raid ausgefallene HDD, die zum Anlass genommen wurde, den Datenpool mit neuen HDDs zu vergrößern. Das finde ich mit zfs und syncoid unfassbar viel einfacher zu handeln als mit BTRFS. Vor allem, wenn man nicht erst nach dem Kopieren von ca. 10 TB herausfinden will, ob man das richtig gemacht hat.)
btrfs nerd shit
Hey #btrfs nerds, what's the current best-practice strategy for migrating to a new (single) drive, without modifying the old drive, which will then be removed. Is it using seeding volumes?
#Linux #btrfs
OH LE BOULET.
Je viens de me rendre compte que j'avais oublié de mettre le répertoire de torrents de mon NAS en NOCOW. Duh.
Correction:
- fermer le client torrent.
- créer un répertoire vide, le mettre en NOCOW (chattr +C nouveau)
- copier l'ancien répertoire dedans (cp -r -v --reflink=never ancien nouveau) (sinon ça gardera les blocs de données qui sont déjà en mode CoW)
shout out to #btrfs
once again i found myself taking good things for granted while the trolls and sociopaths have an audacity to outright shit on them.
i don't usually go ranting about filesystems because my needs and familiarity with storage are modest, and there's a lot i don't understand about it. i'm not in love with my filesystem, and end up with ext4 most of the time anyway.
but copy on write, subvolumes, snapshots were a godsent on many occassions, and no other filesystem comes close. taking a moment to appreciate that now!
I do think that one thing getting glossed over in the bcachefs kerfuffle is that the guy is probably right about #btrfs having remaining reliablity problems - granted I didn't go digging that hard, but I haven't found anywhere where the ~5 year old papers on btrfs becoming unrecoverable in many more underlying data corruption situations than ext4 was addressed, and certainly not with "many of those cases have been fixed."
2/3 Topics #EU_OS needs help with:
1) What is the best way to backup user data for Linux EU OS users? https://gitlab.com/eu-os/eu-os.gitlab.io/-/issues/46 #borgbackup #btrfsbk #btrfs #nextcloud
2) How can unattended deployment with #foreman look like during pilot stage (thus without reconfiguring the network/DHCP yet)? https://gitlab.com/eu-os/eu-os.gitlab.io/-/issues/39 #foreman
3) How can a modern VPN provide extra security for people in home offices or on business trips? https://gitlab.com/eu-os/eu-os.gitlab.io/-/issues/47 #tailscale #headscale #rosenpass #wireguard #openvpn
