I recently installed Fedora on my laptop and I have my old /home
ext4 partition (/dev/sdb2
).
I would like to convert then merge this partition with the btrfs filesystem.
Here is my current setup :
$: btrfs filesystem show
Label: 'fedora' uuid: accd2db4-87ca-4c78-84b9-4500534d63f5
Total devices 2 FS bytes used 7.76GiB
devid 1 size 236.89GiB used 1.02GiB path /dev/sda3
devid 2 size 500.00GiB used 9.01GiB path /dev/sdb1
$: sudo btrfs subvolume list /
ID 256 gen 1007 top level 5 path root
ID 257 gen 1007 top level 5 path home
ID 258 gen 888 top level 256 path var/lib/machines
$: parted -l
...
Model: ATA Samsung SSD 860 (scsi)
Disk /dev/sdb: 1000GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 537GB 537GB btrfs
2 537GB 1000GB 463GB ext4 Linux /home linux-home
As a result I would have a single Btrfs volume (Label: fedora), containing the /dev/sdb2 partition data.
I've found this article to convert an Ext partition to Btrfs, but I don't know if it's possible merge two Btrfs volumes.
