Both the 15GB Btrfs (/dev/sda4) and 30GB Ext4 (/dev/sda5) partitions, previously created with 64k page size (Bookworm), were recognized by the Trixie installer. However, neither could be assigned a mount point without requiring reformatting, implying data loss.

How was the ext4 filesystem created and what was its block size ?
You can see the block size with blkid or tune2fs -l.


The Ext4 filesystem on /dev/sda5 was created using mkfs.ext4 -T largefile4 /dev/sda5.
Its block size is 64KB.

To clarify how the Ext4 filesystem on /dev/sda5 was created and its block size, here is the command output used:


"root@debian:/home/usr# /sbin/mkfs.ext4 -T largefile4 /dev/sda5
mke2fs 1.47.0 (5-Feb-2023)
Creating filesystem with 491520 64k blocks and 8192 inodes
Filesystem UUID: 34c23dcc-c08d-4829-bcea-b1d99286a6e0
Superblock backups stored on blocks:
	65528, 196584, 327640, 458696

Allocating group tables: done
Writing inode tables: done
Creating journal (8192 blocks): done
Writing superblocks and filesystem accounting information: done"


Thanks Trupti.
