Recovery nach gescheitertem Kernel Update
Nach einem fehlgeschlagenen Kernel-Update wechselte der Thecus nach einem Neustart nur noch in eine initramfs Konsole.
Um ein neues initramfs zu erzeugen, hier die notwendigen Schritte:
Achtung: root-Partition auf /dev/sdb2, boot-Partition auf /dev/sdb1 - Dies ist auf das jeweilige System anzupassen!
- Mounten der Root-Platte:
(initramfs) mount -t ext3 /dev/sdb2 /root (initramfs) cd /root
- Root-Directory ändern:
(initramfs) chroot /root
- Mounten der Boot-Partition sowie der notwendigen proc- und sysfs-Dateisysteme
(initramfs) mount -t ext3 /dev/sdb1 /boot (initramfs) mount -t proc proc /proc (initramfs) mount -t sysfs none /sys
- Neustart von udev:
(initramfs) /etc/init.d/udev stop (initramfs) /etc/init.d/udev start
- Überprüfen der /etc/fstab:
- Hier als backup meine version
# /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 /dev/sdb2 / ext3 defaults,noatime,nodiratime,commit=60000,errors=remount-ro 0 0 /dev/sdb1 /boot ext3 defaults,noatime,nodiratime,commit=30000 0 2 /dev/sdb5 none swap sw 0 0 #Data /dev/sda1 /Data ext3 rw,noatime,nodiratime,commit=60000,errors=remount-ro 0 0
- Löschen und erzeugen eines neuen initramfs:
(initramfs) cd /usr/sbin (initramfs) update-initramfs -v -d -k 2.6.26-1-iop32x (initramfs) update-initramfs -v -c -k 2.6.26-1-iop32x -b /boot
