Rescue installation with super block.

siery · 01-08-2016, 12:15 PM

Hey. I wanna make some system reinstallation at my pc sience i install there only kernel and basic system. I get Raspberry Pi from a friend so i decide to set up my server there

. So the thing is i dont know how to reinstall or use rescue installation mode on encrypted partition. When i try to use this partition i can read this info in syslog:

Code:

[id] isofs_fill_super: bread failed, dev=sda2, iso_blknum=16, block=32
[id] EXT4-fs (sda2): unable to read superblock
[id] utf8 is not recomended IO charset for FAT filesystems, filesystem will be case sensitive!

I was most surprised about the last communicate. Why utf 8 IO is not recommended, isn't that usually for linux IO to be case sensitive

?
Any ways, its my pc so i know disc password. Can i encrypt it somewhere from installation or maybe before?

The system that is installed at my pc and the one i'm trying to reinstall is Debian Jessie 8.2.

Thanks, Siery.

It tried iso9660, &ext4. you need vfat. Load the module.

How, what module? Can u give me some longer explanation? Thanks.

Try

Code:

sudo modprobe vfat

Vfat is an often used but lousy filesystem because it is interchangeable between OSes. vfat.ko is a kernel module for reading vfat. No long explanations - I jave one arm paralyzed atm.
