Server crash

Not the sudo RaspberryPi, also knows as the CuBox, nor the Linux/Raspbian is making the most problems of my server, but very often it’s the hardware.

This time it was the hard disk. A Toshiba one, working since almost 3 years now, quite ok, only troubled by the other hardware problem I faced so far with the server, the USB hub.

Now the server was down. Normally this was not a big deal so far, just make a

fsck -y /dev/sda1

and everything was OK after some reboots.

This time it was different. The file system check could not recover, although the disk was still readable. So I bought a new one, formatted it, copied the data from the old disk preserving the file attributes/permissions.

mkfs -t ext4 /dev/sdc1
mount /dev/sdc1 /mnt
cp -pr /media /mnt

Finally it turned out that finding the bad blocks of the old hard disk helped to recover that as well:

fsck -y -c /dev/sda1

Then I made a snapshot of the new system with

tar -zcvpf /mnt/backups/fullbackup.tar.gz --directory=/ --exclude=mnt .

Let’s see how long it lasts now…

finding the problem took me ~4h,
solving it with the command running the fsck took ~6-8h. This depends mainly on the size of the hard disk.

Yesterday i also had some problem with my external hard disk that i formatted as ext4 filesystem to be compatible with linux environments. The mounted hard disk suddenly became read only.
==> fsck -y -c /dev/sda1
Running this command helped me. Thanks Gerhard.
