/dev/pride/rt: Too many reserved group descriptor blocks while setting up
superblock
[EMAIL PROTECTED] :(
The block device in question is exactly 20GB large. It seems I cannot
use -O resize_inode on block devices larger than 15GB, where it
reserves space for growing the filesystem up to 15TB. If there is a
limitation on how large the resize_inode can be, mkfs should probably
just reserve as much as it can and leave it at that if the default size
exceeds the limitation. It attempts to reserve space so the filesystem
can grow to 1024 times its initial size, right?
By the way, -O resize_inode isn't mentioned in the manual page. I've
attached a suggested patch.
Kind regards
