Fix EXT4 fs bad geometry block count exceeds size of device

The default value is 4096 bytes (4 KiB), the minimum is 512, and the maximum is 65536 (64 KiB). XFS on Linux currently only supports pagesize or smaller blocks.

Valid block-size values are 1024, 2048 and 4096 bytes per block. If omitted, block-size is heuristically determined by the filesystem size and ...

How do I create an EXT4 file system with block size 1024 and no reserved blocks? ... Translate badblocks result from 1024 block size to 4096 block ...

With the default block size of 4KiB, each group will contain 32,768 blocks, for a length of 128MiB . The number of block groups is the size of the device divided by the size of a block group. All fields in ext4 are written to disk in little-endian or

ext4 ; 16–256 TiB (for 4–64 KiB block size) · 4 billion (specified at filesystem creation time) · 255 bytes (fewer for multibyte character encodings such as ...

If you have a filesystem block of 4096 and you physical sector size is 512 you will have something like this $((4096/512)) = 8.

The primary copy of the ext4 superblock is located at offset 1024 bytes from the beginning of the file system, and is 1024 bytes in length.

On ext4, just use tune2fs to check your block size, as follows (change /dev/sda1 to your own device path):

At the moment, the default size of a block is 4KiB, which is a commonly supported page size on most MMU-capable hardware. This is fortunate, as ...

From all the things I read EXT4 can only do 4KB block size. I will hav to research the other recommendations you said :-) Upvote 1. Downvote
