Current64: mke2fs (aka mkfs.ext4): 64-bit filesystem support is not enabled.


Current64: mke2fs (aka mkfs.ext4) complains about 64-bit filesystem support not being enabled. E.g.:
Code:
root@riposo:~# mke2fs -text4 -L sda14  /dev/sda14
mke2fs 1.44.1 (24-Mar-2018)
...
64-bit filesystem support is not enabled.  The larger fields afforded by this feature
enable full-strength checksumming.  Pass -O 64bit to rectify.
...
I assume this message started to be issued quite recently (with this 24-Mar-2018 version ?), but I do not know for sure.

It is enabled at format time if the size of the partition being formatted justifies it. Otherwise, using 64-bit filesystem support breaks LILO. It also broke GRUB in the past, but I believe that caught up to it quickly.

I haven't checked LILO again since setting e2fsprogs to use auto_64-bit_support almost 2 years ago, so if I'm incorrect and it works now, let me know. Or, if I'm correct and you have patches to address this, that would also be welcome.

I ran "mke2fs -text4 -O 64bit -L sda14 /dev/sda14" and other than the 64-bit message not being issued did not notice anything "new": sda14 could be mounted, written to and read from as before. Actually I found no indication at all that sda14 was 64-bit now.
I then ran the above mke2fs command for my /dev/sdd5 grub2 partition. Grub2 booted from it without a hitch -- in BIOS mode only, as UEFI requires the partition to be fat32.
I then ran the above mke2fs command for my /dev/sda15 partition and restored my Current64 backup to it. And again grub2 had no problems booting it.

I do not (and never did) run LILO, so I cannot confirm whether or not LILO works now with a 64-bit ext4 partition.
