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. Thank You Larry Linder -- -- Steven C.

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 Troy -- __ Troy Dawson daw...@fnal.gov (630)840-6468 Fermilab ComputingDivision/LSCS/CSI/USS Group __
Re: SL 5.4 to 5.5 upgrade-problem
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
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.
