It looks like the filesystem doesn't occupy the whole partition -- you can resize it using `resize2fs`; see the man page for details.

Yeah, I try to do it on running environment becouse resize2fs has the ability to resize mounted partitions but unfortunelly:

Code: Select all

└─#! umount /dev/mmcblk0p2

└─#! resize2fs /dev/mmcblk0p2
resize2fs 1.42.5 (29-Jul-2012)
Filesystem at /dev/mmcblk0p2 is mounted on /; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 1
resize2fs: Read-only file system While checking for on-line resizing support

Trying it on laptop with SD Card mounted have chance to success without losing my data?
