Any rumors on larger persistence?

[ToddAndMargo]

Hi All,

Anyone know any rumors as to if we are going to
be able to have more than 4 GB of persistence
in the future?   Ext2/3/4 perhaps?

It is really difficult to discipline myself to
keep it under 4 GB.

Many thanks,
-T

You could run a normal version of the OS on your device instead of the 
live image. That allows you to update the kernel and allows for reclaim 
of space used by updates.

Overlays greater than 4 GiB are available now with ext4 formatting of the
Live CD device.

For example,

livecd-iso-to-disk --reset-mbr --format --overlay-size-mb 10000
home-size-mb 1024 --unencrypted-home /path/to/iso /dev/sde

produces a Live CD with a 10485760000 byte overlay file.

Hi Fredrick,

Very cool.  Thank you!
I could not find this on the link you sent.

Do you first format your stick with ext4? Or,
leave it unformatted with a single blank
primary partition?

Both are possible.  The latter requires the livecd-iso-to-disk --format
option, which now defaults to ext4.

See the usage section at the top of
https://git.fedorahosted.org/cgit/livecd/tree/tools/livecd-iso-to-disk.sh

Hi Fred,

I have to use all the old stuff as I am in Scientific
Linux 6.5 (RHEL 6.5 clone).  Do you know if my version
will support the above?

liveusb-creator-3.12.0-1.el6.noarch

Many thanks,
-T

​
The ​
livecd-iso-to-disk
​
installation script
​
is available in the livecd-tools package,
https://apps.fedoraproject.org/packages/livecd-tools

It is often saved in the /LiveOS/ directory of the Live CD iso and on a
loaded device.

Hi Fred,

Oops, copy and pasted the wrong one.

$ rpm -qa *livecd-tools*
livecd-tools-13.4.5-1.el6.x86_64

The latest, from the link you sent me is 21.1.1

Do you think my old, dilapidates version has the ext4 support?

Manya thanks,

​You can check here,
https://git.fedorahosted.org/cgit/livecd/tree/tools/livecd-iso-to-disk.sh?h=...

Looks like ext4 was not supported in that branch, but ext3 will support
upto 16 GiB with 1 KiB blocks.

Looked over the script.  You have to admire the guy who wrote
that.  Wow, he worked his rear end off on that one!

Hi Fred,

This worked:

# livecd-iso-to-disk --reset-mbr --format --overlay-size-mb 6624 
--unencrypted-home Fedora-Live-Xfce-x86_64-20-1.iso /dev/sdc

# ls -al /media/LIVE/LiveOS/overlay-LIVE*
-rw-r--r--. 1 root root 6945767424 Jun  2 14:21 
/media/LIVE/LiveOS/overlay-LIVE-080e62f1-2731-4790-a1eb-48175d703185

* UNFORTUNATELY:  THE PERSISTENCE DOES NOT WORK *

Live this feature!  Run once with too big and adjust downward.

Unable to fit live image + overlay on available space on USB stick
+ Size of live image:  582
+ Overlay size:  7000
---------------------------
= Requested:  7582
- Available:  7206
---------------------------

I hope the persistence problem gets fixed soon.

Persistence works for me.

Check dmsetup status
and
dmsetup table

See that the live-rw snapshot has been set up on a loop device backed by
the overlay file
and not a temporary overlay, which would be the fallback if no overlay was

If you don't get similar results, check the system journal for errors on
the filesystem.

Hi Fred,
It will be a few days before I get enough office time to try
this out.

I do believe you are using a later version than me as
"--unencrypted-home" is not supported.

If it helps with the troubleshooting process, persistence
does work with the "Fedora LiveUSB Creator" GUI.  But,
I can only get 4 GB of it.

Thank you for the help!

​I used the livecd-iso-to-disk that came on the​
​
Fedora-Live-Xfce-x86_64-20-1.iso in the /LiveOS/ directory.

--unencrypted-home only has meaning if you have specified a home.img
filesystem for /home through the --home-size-mb option.
It's presence on the command line had no effect.

Hi Fred,

Thank you for helping me with this.

From the host machine ("#" is root's prompt):

I am at the mercy of EPEL.  They will update to
the latest version when they do and not a moment
sooner.

Also note that persistence works fine with "liveusb-creator"
(the GUI), but that you can not get more than 4 GB
of persistence.

I'll accept patches since it is a feature that already existed, but I
have to say that this is a *really* bad idea. You're going to lose data.
You are better off partitioning the device and mounting it as /home/ or
whatever. I actually tried using this last week for a temporary install
while waiting for a new harddrive. System didn't like to wake from sleep
properly so I had to pull the plug, and guess what? Corruption - I had
to recreate the USB stick.

Hi Brian,

I am not following your "*really* bad idea" remark.
Is there something wrong with EXTx in this environment?

Wouldn't the corruption you speak of have happened with
a FAT32 partition as well?

Hi Brian,

In my version,

$ rpm -qa *livecd-tools*
livecd-tools-13.4.5-1.el6.x86_64

persistence does not work.  EXTx file system does, but
it is unless unless without the persistence.

I would appreciate you porting the new stuff over.
