Can you check with "-T largefile" and without -T for completeness ?
Hi,
Yes, I have performed the additional tests you requested for
completeness.And the block size output for newly created partitions are
as follow:
root@debian:/home/usr# /sbin/tune2fs -l /dev/sda5 | grep "Block size"
Block size: 4096
root@debian:/home/usr# /sbin/tune2fs -l /dev/sda4 | grep "Block size"
Block size: 65536
The results are the same: the Trixie installer was unable to use either
partition without requiring a reformat.
The partition created with -T largefile was incompatible.
The standard ext4 partition created without any -T option was also
incompatible.
This creates a clear risk of data loss for users upgrading from
Bookworm. To ensure a safe user experience, a dedicated 64k installer
image is a necessity. Providing this for Trixie, and making it the
default for future ppc64el releases, would prevent data loss and align
Debian with platform standards.
Thanks Trupti.
