Troubleshooting
IMPORTANT: This description is valid for SL6 only. For SL4 and SL5
LiveCD please see Troubleshooting SL4 and SL5 Live system
Troubleshooting SL6 LiveCD/DVD
- LiveCD hangs during booting
Try to boot with one or more of the following boot parameters: apm=off acpi=off noapic noswap nomodeset all_generic_ide pci=nommconf
- No graphics (I)
Try to boot with Boot (Text Mode). This will start the LiveCD without X.
Afterward login on the text console and try to start the X Server with the command startx.
- Can not resize partitions with Gparted
Gparted can only resize partitions if all partitions are unmounted of the involved hard disk.
In case you have a swap partition on your hard drive, the Live system will use it for swapping.
Either start with boot option noswap or turn of swap as root on the running Live system
with swapoff -a
- SATA DVD/CD-ROM drive
Some SATA DVD/CD-ROM drive are not recognized correctly.
Try to boot with boot parameter all_generic_ide.
Troubleshooting SL6 Live USB
- If you use data persistence, have a look at limitations for data persistence.
- I have used all disk space of the primary system overlay image.
Now I see a lot of I/O errors and my USB Live stick does no longer boot.
Unfortunately your persistence data is lost. But you can start with a new empty persistent overlay.
On the USB stick delete the old and corrupt overlay image in the folder LiveOS
cd LiveOS
rm overlay--ABCD-1234
where overlay--ABCD-1234 is the name of the overlay image (will be different in your case).
Now create a new empty overlay image (count= defines the size in MB)
dd if=/dev/zero of=overlay--ABCD-1234 count=1024 bs=1M
- How is the UUID of the persistent overlay defined?
The following command will show you the UUID of your USB stick partition
(assuming it's /dev/sdb1)
blkid -s UUID -o value /dev/sdb1
- How can I find out whether presistent overlay is working?
The primary system overlay image (/LiveOS/overlay-X-YYYY-ZZZZ) should be mounted on /dev/loop4,
the persistent /home image (/LiveOS/home.img) on /dev/loop5.
To show what's mounted on /dev/loop4 and /dev/loop5 run
losetup /dev/loop4
losetup /dev/loop5
