so, for an SSD: #ext4 or #btrfs?

(by this point i know that btrfs is not as suitable for HDD storage, because it doesn't have a way to detect and avoid "bad blocks") #linux

So you hit enter too fast after the dreaded `rm -rf` in the wrong directory but, of course, your backup saved the day. … No? Don't panic; you are not alone and there are tools which can help you out on #filesystem level. In my case, it was `btrfs-undelete`, but there are similar programs for Ext4. Data recovery is cumbersome and time-consuming, but not impossible. And next time, backup, backup, #backup !

FINALLY the first oDroid HC4-p is fully loaded with hard drives (i.e 2)

#BTRFS RAID1 setup.
Gluster connected.

Busy taking data.

There was one hiccup where it initially become unresponsive after starting the gluster brick replacement...but a power cycle SEEMS to have sorted that out.

fml.

5 hours trying to make a stupid #Ansible task setup a #BTRFS subvolume mount.

And I had a typo in the the subvolume name.

🤦‍♂️

#Btrfs-progs 6.15 is out:

"'This is more of a bugfix release with a few feature updates.

Changelog:

* mkfs: new option --inode-flags to specify flags/attributes for inodes/directories/subvolumes
[…]
* rescue: add new command fix-data-checksum, selectively fix or find mismatching checksums
[…]"'

#askfedi To my fellow nerds out there, is #btrfs not properly compatible with #fscrypt on #Fedora 42 using #systemd-homed yet or did I just fuck something up? Luks works well and is more secure because it encrypts metadata but I really wanted to try dynamic encrypted home directories.

BTRFS Subvolumes On Debian Trixie - Easiest Tutorial

Excited for Btrfs RAID1's "preferred read device" feature in Linux 6.14. This allows to have one fast device, example SSD backed bcache device and other slow cheap hard drive. We can set the bcache deice as preferred read device so reads are always fast.
It also wears down only one disk reducing the chance of both the disks evenly wearing out which increases the chances of both of them failing around the same time.

From the pull request:

> more read IO balancing strategies (experimental config), add two new
ways how to select a device for read if the profiles allow that (all RAID1*),
the current default selects the device by pid which is good on average
but less performant for single reader workloads
- select preferred device for all reads (namely for testing)
- round-robin, balance reads across devices relevant for the requested IO
range

I have a #btrfs filesystem of Theseus. Created on Debian Jessie (2015, 3.x kernel) with a 1TB + 2TB set of disks. This same filesystem has come with me as I’ve swapped hardware and distros several times. None of the original disks remain but I’ve enjoyed how this filesystem makes the best use of space in spite of the disks always having been mismatched. I’ve replaced drives one at a time using whatever capacity is cheapest per TB at the moment. It’s currently running on 3x8TB + 1x16TB.

Got a problem with upgrading and timeshift-autosnap on Manjaro with btrfs.
After getting "failed to run transaction hooks" every time, I could get it to work with

$ sudo timeshift-autosnap

and selected a new (the old) backup drive.
No clue why it lost the previous settings.
After that I could upgrade my system again.

I should have gone with ext4 instead of #btrfs I'll guess.

Anaconda on the Fedora Server install ISO doesn’t offer btrfs. Confusing.. Do I need to use the Workstation ISO to get btrfs in Anaconda..?
( And yes, I do want Anaconda in this instance. )
#Fedora #Anaconda #btrfs

Abandoné mi estrategia de respaldos con #Timeshift Btrfs+Rsync y opté por #Btrbk que crea instantáneas #Btrfs locales y realiza respaldos externos incrementales. Además, permite manejar diferentes subvolumenes al mismo tiempo a distinta frecuencia. Por ejemplo, puedo programar instantáneas globales del sistema de forma diaria, y al mismo tiempo, varios respaldos por hora de un directorio de trabajo, una base de datos, en particular. No tiene interfaz gráfica, pero su potencia es increíble 🤩

Which Linux file system do you prefer using?

#Linus #file #system #ZFS #Btrfs

Both ZFS and Btrfs are advance file systems designed for Linux. They both offer features like RAID, compression, and snapshots.

But ZFS is generally considered more mature, reliable, and robust. ZFS is also a popular solution for enterprise.

Btrfs is more Linux-centric solution. Btrfs tends to be easier to integration and use with the Linux kernel.

#ZFS #Btrfs #file #system #RAID #compression #snapshots #Linux #kernel

I have a bunch of old documents on my computer separated in an "old documents" folder. Currently they are not compressed.
If I compress my "old documents" into a tar.zst archive, will I increase to decrease the probability of them becoming corrupted?

My home partition is using BTRFS if it matters. #BTRFS

Some refinements to "oops" including not only finding deleted files in Snapper snapshots but also finding previous versions of existing files.
