#lvm #lvm2

Each time I needed to migrate my data to a new SSD with LVM and LUKS, I struggled a lot, until I figured this out properly. I have documented all necessary steps in this document:

#lvm #lvm2 #luks

#Selfhosters and knowledgable #LVM2 people I need your help. I currently have 4 hdds with physical LVM2 volumes hosted on a mini-pc and this is mounted as a logical volume to hold all my media and home server stuff.
I want to move the four drives to a new machine but am not sure the best way to go about this.
Any help or boosts for reach are appreciated.

Also, if you've never used #lvm2 I highly recommend it. You can throw a bunch of spare drives together on an old dell powerEdge server and have a cheap Plex server, #minecraft server, etc. Just be aware those ~$100 powerEdge servers are EoL so they shouldn't be open to the Internet or hold anything critical (also for safety install #linux as current Windows versions don't support them at all).

#LVM2 2.03.26 has been released (#LVM / #LogicalVolumeManager / #DeviceMapper / #RedHat) https://sourceware.org/lvm2/

I finally published my #libvirt hook script for managing locks in a #lvm2 shared volume group.

I’m setting up network level backups at the homestead. 8Tb HDD just landed. Dropped #lvm2 on it. I set up another #vorta profile to backup my laptop. I’ll set up the spouse’s MacBook for backing up with vorta as well. Then onto the #RaspberryPi devices.

Next up will be setting up apt-mirror so that all my devices can update without leaving the LAN.

Help me #arch #linux mastodon!
I'm trying to install Arch on a Thinkpad using #luks + #lvm2 + #btrfs. The goal is to have an encrypted swap *partition* so I can suspend/resume. I'm new to BTRFS, so I'm thinking my problem is somewhere there. Every time I try to boot, I get a "Failed to mount /sysroot" follwed by dependency failures for initrd root file system, mountpoints configured in the real root.

I've tweaked my options several times. Currently I'm at rd.luks.name=UUID=name root=/dev/mapper/crypt-root rootflags=subvol=@.
mkinitcpio has HOOKS=(base systemd plymouth autodetect modconf kms keyboard sd-vconsole block sd-encrypt lvm2 filesystems fsck) with BTRFS loaded as modules and binaries.

HELP??

Ich erlaube mir zu relativieren:

Es ist ja keine Frage ob jetzt #ZFS, #LVM2 oder #BTRFS

Die Frage ist eher, ist es heutzutage noch empfehlenswert, mit starren Partitionen zu hantieren? Oder sind flexible Methoden mit happy end (snapshots, raid, größenänderung, ...) nicht von vornherein empfehlenswerter.

Was die exakte Technologie angeht, mit der man das Problem löst, ist ja Problemstellungs-, Gewohnheits- und Befindlichkeitsabhängig.

Mein Standardsetup ist übrigens #lvm2 mit allem drin als Volumes. root, boot, swap, LVs der virtuellen Maschinen, etc.

Ich mach bei SSDs auch gerne RAID über lvm2. Das hat den Charme, dass man flexibel zwischen Redudanz und verfügbarem Speicher wählen kann. Auf meinem Notebook zum Beispiel läuft das so. Ich finde es nicht kompliziert.

Geht mit #btrfs und #zfs sinngemäß genauso, ist geschmacksfrage und nix neues.

Daher schien mir der Ratschlag etwas verwunderlich.

@LGUG2Z
#ZFS is a fancy #enterprise file system. Its upside is that it offers RAID functionality without RAID hardware.

What do? Keep it simple. You are not #enterprise.

For what you do, it looks like any #Linux distro with #LVM2 partitioning will do just fine.

I'd focus on data recovery. Having 4 hard drives lowers your MTBF.
