I wish it were that easy... I'm not even sure what I want to do is possible, but here we go...
I have a bunch of CuBox's that boot off SD Cards. The CuBox's use the bootloader called U-Boot. And when I do a straight clone from one card
to another I am unable to boot the cloned SD Card. During the boot process, after the U-Boot screen, I get the error during boot log messages that says;
"Failed to find boot device"
I Believe this is because when I did the first boot of the source sd card (*the one that works), U-Boot writes data specific to that SD Card in
the u-boot.img file and also a compiled file called boot.scr. I also believe it records the Offsets, or has them pre-recorded, of the Kernel image file
that is flashed to the SDCard. The boot.scr file contains the kernel image's addr/offset for where to find it...
Another thing I tried was after I cloned the working SD Card to a new one, I mounted the cloned card to my laptop and ran the command:
Which I believe recreates the boot.scr and boot.script files (*which contains all the boot env variables and boot cmds, etc...)
Now, after I did that and I try to boot the SD Card again, I get MUCH further along in the boot process, but I then get stopped at an error message
that says this below (*the name there is the by-id name of the ORIGINAL SD Card...):
So I'm thinking the device name is getting written somewhere else in the boot partition, possibly in the zImage-3.14.14-cubox-i kernel
image file or maybe in u-boot.img file... So I thought I would try to take a fresh sd card that has had the OS image flashed to it, but has never
been booted, and copy the MBR and boot partitions from that FRESH SDCard and overwrite the MBR and boot partitions on the CLONED card
and see what happens...
I'm doing this becuase I need to configure about 15 of these CuBox's and I was hoping I could simply configure one SD Card exactly how I want it
then clone the SD Card for the other CUBox's to save A WHOLE LOT OF TIME...
I know when I change Hard Drives on my OpenSuSE laptop and I clone the HDD to a new Drive, I usually just need to edit the HDD names in GRUB and I'm
good to go, but this seems more complicated...

Hi
I'm doing some resilience testing and need to write a script to consume all of the available disk space on a partition and then to free it up again.
This would need to be -
Safe
Dynamic, in that it calculates the free space prior to consuming it.
I might want to go on to consume a... (7 Replies)
I have a RHEL 5.3 machine with the following partitions and free space:
Free space on the partitions
/ : 74GB
/boot : 81MB
/var : 73GB
/home : 37GB
/icat : 758MB
/opt : 1.5GB
Now is it possible to allot a free space of some other partitions to /opt? I want around 100 GB more space... (4 Replies)
