New Users / Install help - ext4 vs. ext2
« on: May 22, 2019, 08:04:59 am »
What is the 'secret' to install Peppermint 10 on an older Apple Mac Mini  3,1 (late 2009 Intel 2.53Ghz Core 2 Duo w/8Gb RAM, 640Gb HD and a NVidia GeForce 9400/256Mb Video RAM) ... I currently have it partitioned with /dev/sda1 bios grub 1Mb, /dev/sda2 ext4 mount point / - size= 600Gb, /dev/sda3 efi 20Gb, /dev/sda4 swap 20Gb) ... right as I am selecting to install (erase all and install option), I get an error message that says:

" The partition /dev/sda2 (The ext4 600Gb partition) assigned to / starts at an offset of 3072 bytes from the minimum alignment for this disk, which may lead to poor performance.   Since you are formatting this partition, you should correct this problem now by realigning the partition, as it will be difficult to change later.  To do this, got back to the main partitioning menu, delete the partition, and recreate it in the same position with the same settings.  THis will cause the partition to start at a point best suited for this disk.”


Deleted and changed the /dev/sda2 partition to ‘ext2’ (was ext4) and now it is installing !!!  Will be great to finally put this PC back in use! :) THanks Peppermint OS developers!

THe OS Seems pretty fast so far - :)

My question is ... what is the difference between ext2 and ext4 and why did the installer not like ext4?  (bear in mind - this is an EFI machine - wish it were regular old BIOS).
Thanks,
Dennis
