lubuntu-14.04-alternate-powerpc.iso missing fsadm so lvreduce --resizefs aborts... [12.04 desktop CD live-powerpc success]

Booting live-powerpc on the iMac G3 from a powerpc 12.04 lubuntu desktop CD (burned from the .iso) allowed the following sequence (# ... is comments):

sudo apt-get install lvm2
# The above installed fsadm as well as well as lvmreduce and the like.

sudo vgchange --available y G3volgrp
# I needed to activate the logical volumes in the kernel before the below was allowed.

sudo lvreduce --resizefs --size -45G /dev/G3volgrp/G3root

On reboot to the internal drive (after the above) things seem fine.

Thanks again for the pointers Phill. So there is a CD based work around readily available as long as lubuntu 12.04's .iso for using live-powerpc is readily available.

Thanks for the pointers Phill.

I have submitted the issue as Bug #1338888. (Turned out that I had an old account from
some 2008 activity, not that I remember what it was about.) I'm perfectly happy to leave
1338888's status, importance, and the like to those with more context than I currently
have. (My first submittal --unless I made one in 2008.)

I'm going to be away from the iMac G3 for a while so I'll not being trying any alternatives
for that time.

Hi Mark,

I'm sure the others will scream at me, but as 14.04 desktop is over sized, it will not fit on a CD. Alternate obviously does not have LiveCD option.... However..... have a try of the 12.04 lubuntu desktop PPC, which should have the ability to boot as LiveCD and have the ability to invoke LVM stuff.

head over to and see if it works for you. If that link is slow / not working, then feel free to use my mirror which for 12.04 is at

I'm not a PPC person, but I do know lubuntu is your refuge and I will do what ever I can to help out.

Thanks for helping on PPC,

My original report to the list was informational (and cross checking) since I did not find any references to the issue when I looked around. My report did not even ask for help.

Installing from the same .iso installed fsadm and the lvm software just fine and I also had no trouble setting up my lvm configuration in the first place. I've also been able to do everything that I wanted that is allowed for use on a already existing lvm context with / coming from the lvm live. (My use is at the simple end of things for lvm so far.)

But one can not do an action that includes a reduce (shrink) to a live / (the root file system). So I tried to do that from the rescue-powerpc selection from the CD (so booted from different root). This is what I was reporting as not covered by the rescue-powerpc use of the CD. (apt-get is also missing from that context.) It may be that lvm's coverage for rescue-powerpc is just not to be complete due to space requirements and the relative priorities for what can be done fairly directly booted from that media via that selection. Such is not for me to say.

Quoting ...

As far as I can tell this is still true. For my old iMac G3 context larger media does not work (the internal slot-drive is a CD-only one). I've not got around to setting up yet another alternate boot technique to some other root file system in order to do the reduction from where I can get everything required in place. At some point I will take the time to deal with doing that.

I've not yet created an account to submit bug reports with. It may be a bit before I get to that.

I recall that desktop PPC went over size. Julien took a sword to the alternate in order to ensure it is CD sized. In my humble opinion, people wanting to use LVM's should know how to install the tools needed. (I use LVM's, run 11 KVM machines and also SEL :D ).

Do feel free to raise a bug report, I'm hopeful that it is not a massive job for Julien to add in the library for 14.04.1, but I also do not want to peck him to the point he gets fed up of PPC.
