During an install, the partition that is going to become /
would be mounted on /mnt/sysimage and
that which will be /usr would be on /mnt/sysimage/usr.


My guess is that update ran out of disk space, and the the sysimage/usr is
removed after ERROR is detected and REBOOT message is displayed.


You shouldn't actually have to do an anaconda install to get from
SL54. to sl5.5, a yum upgrade should work.
But yes you ran out of disk space on /usr, which is by far where
most of the distribution lives.


Is there anyway to change the location of sysimage/usr to some other disk on
the system?

How big is your / partition?  Is it enough to contain all that it contains
now plus all the 8GB of /usr plus the extra stuff you still have to put 
in?


do you have any other partition that has 2G or more free?

If so, you could boot in single user mode and move the contents of
/usr/ to whatever partition is free.
But it may be better to first try to clean out unused user files
out of /usr because there is for sure not 8GB worth of OS files that
would be there.



The sda? contains all the system directories and is 36 G, about 1/2 of it is
uncommitted.   /usr is 8G and 94% full.  Other directories have at least a G
of spare space.

I need to change partition sizes but hate to waste a lot of time guessing.

Hi Larry,
One quick question before I proceed.  Are you doing a real upgrade or 
an install
An upgrade is where SL 5.4 stays there and you just update the 
packages in it.  If that is the case, using the installer isn't the 
recommended way of updating it.  It is much easier to to an upgrade via yum.

http://www.scientificlinux.org/documentation/howto/upgrade.5x

An install is where you wipe and reformat everything except maybe your 
home and data partitions.


I am going to assume that you are doing a install or SL 5.5 over a 
previously installed SL 5.4.


If you are doing this, then you *need* to reformat the partitions that 
do not contain your home area or data.  Otherwise the install starts 
adding to what is already there, and as you saw, it can fill up.


Patitions you should format if you are doing an install.

/
/usr
/var
/boot

As Steve said in a previous email, if you can fit everything onto / 
there is often no reason to create a /usr.  Take that space and add it to /


Hopefully this is enough information, along with Steve's,  to get you going

Re: SL 5.4 to 5.5 upgrade-problem

2010-07-22 Thread Larry Linder
Because we are in a little town (wide spot in road) the DSL is not the most 
reliable.  That is why I down loaded the 8 disks from another source and 
wanted to update systems to SL 5.5.
This install try was an update and not a new installation.
There have been a lot of additions to this system, for doing FFT, Power 
Spectral Density, and a lot of signal processing.   Unfortunately /usr has 
expaned beyond our first guess and /usr/local is almost empty.
Since these may not be adjacent partitions.  Is there anyway to expand /usr 
and shrink /usr/local.  

Thanks for the insight.

Re: SL 5.4 to 5.5 upgrade-problem

2010-07-22 Thread Steven Timm

What you want to do, can be done with a combination of parted
and resize2fs.  Take good backups first.  It would have been
easier if you were using LVM.

basic strategy, resize2fs to shrink /usr/local file system,
then parted to shrink /usr/local partition,
then parted to grow /usr partition.
The last time I did this I had to actually delete one of
the partitions out of the partition table and then re-create it
in the same spot.  Not for amateurs.

steven timm has right suggestion, but i believe he missed;

 Since these may not be adjacent partitions.  Is there anyway to expand /usr
 and shrink /usr/local.

so, how about posting your /etc/fstab, and post results of;

 df -B 1024|grep /dev/|sort


do you have any room for an additional large hard drive?

do you have another system that you can mount hard drive that you are
having space problems with?


no further commitment or comments until you reply to above, as it will
determine how to proceed.
