I’ve flashed the Debian build and currently playing with it.
I suppose the partition ‘userdata’ (/dev/sdd13) can be mounted to provide more space.
I’ve also supposed it contains the ext4 partition (from Android) but it is not (nevertheless it contains some data).
At the same time /data/sdd12 (partition ‘reserved’, label data) seems contains ext4 filesystem but mounting it is failed with kernel message:
EXT4-fs (sdd12): bad geometry: block count 6291456 exceeds size of device (256 blocks)
BTW, testdisk also sees something in /dev/sdd12 (label ‘data’):
Disk /dev/sdd - 31 GB / 29 GiB - CHS 3811 64 32
Partition Start End Size in sectors
P MS Data 70912 87295 16384 [BOOT]
P MS Data 94976 1295103 1200128 [rootfs]
>P MS Data 1495808 7787263 6291456 [data]
So, what’s wrong here?
Should I correct /dev/sdd12 somehow? or should I instead make new empty filesystem on /dev/sdd13 ?
