/ Partition nur Read-Only nach Upgrade!

Hallo Zusammen,

ich brauche dringend Hilfe. Mein System (Beaglebone Black mit Ubuntu 14.04) startet nach einem apt-get upgrade nicht mehr korrekt.
Es kann die mmcblkp1 Partition nicht mehr korrekt mounten und setzt das filesystem dann auf Read-Only.

Was ist denn da passiert?

Die fstab sieht so aus:

proc /proc proc defaults 0 0
/dev/mmcblk0p2 / auto errors=remount-ro 0 1
/dev/mmcblk0p1 /boot/uboot auto defaults 0 0
#
#SD-Karte als Speichererweiterung
#UUID=3b8a54a0-971a-4834-9323-afa6075562f3 /media/SD_Karte ext4 errors=remount-ro,relatime 0 2

#Externe 1TB Festplatte
#UUID=345fa145-2663-4986-9278-5e5862cf6791 /media/mydata ext4 defaults 0 2
#UUID=805e24e9-bcdb-4b5c-b6e5-1af6f78750a2 /media/backup ext4 defaults 0 2

Code:

---

sudo mount -o remount,rw /

---

funktioniert.

Ich glaube das,

Code:

---

Disk /dev/mmcblk0boot1 doesn't contain a valid partition table
Disk /dev/mmcblk0boot0 doesn't contain a valid partition table

dass ganz "normal" ist.

Was mir vor dem Upgrade noch aufgefallen ist, ist das ich nur noch wenig Speicherplatz hatte. Ca. 100MB und jetzt nur noch
