Hello Jim and everybody who is willing to help, Runlevel 1 did not help, but I have found the source of the problem, unfortunatelly not the solution: The source of the problem is that I have deleted some installed files manually, without RPM. Anyway I think rpm should be robust and it should not hang if some files are deleted. It should display some warning instead. I have used -vv option and here is deailed output from rpm: rm -f /var/lib/rpm/__db* rpm -evv --justdb kernel-xen0-devel kernel-xenU-devel --allmatches D: opening db environment /var/lib/rpm/Packages create:cdb:mpool D: opening db index /var/lib/rpm/Packages rdonly mode=0x0 D: locked db index /var/lib/rpm/Packages D: opening db index /var/lib/rpm/Name rdonly mode=0x0 D: read h# 468 Header SHA1 digest: OK (xxx) D: opening db index /var/lib/rpm/Pubkeys rdonly mode=0x0 D: read h# 1040 Header sanity check: OK D: ========== DSA pubkey id xxx xxx (h#1040) D: read h# 732 Header V3 DSA signature: OK, key ID 4f2a6fd2 D: read h# 117 Header SHA1 digest: OK (xxx) D: read h# 678 Header V3 DSA signature: OK, key ID 4f2a6fd2 D: ========== --- kernel-xen0-devel-2.6.12-1.1454_FC4 i686/linux 0x0 D: opening db index /var/lib/rpm/Requirename rdonly mode=0x0 D: ========== --- kernel-xen0-devel-2.6.13-1.1532_FC4 i686/linux 0x0 D: ========== --- kernel-xenU-devel-2.6.12-1.1454_FC4 i686/linux 0x0 D: ========== --- kernel-xenU-devel-2.6.13-1.1532_FC4 i686/linux 0x0 D: ========== recording tsort relations D: ========== tsorting packages (order, #predecessors, #succesors, tree, depth, breadth) D: 0 0 0 3 1 0 - kernel-xenU-devel-2.6.13-1.1532_FC4.i686 D: ========== successors only (0 bytes) D: 1 0 0 0 1 1 -kernel-xen0-devel-2.6.12-1.1454_FC4.i686 D: 2 0 0 1 1 2 -kernel-xen0-devel-2.6.13-1.1532_FC4.i686 D: 3 0 0 2 1 3 -kernel-xenU-devel-2.6.12-1.1454_FC4.i686 D: closed db index /var/lib/rpm/Pubkeys D: closed db index /var/lib/rpm/Requirename D: closed db index /var/lib/rpm/Name D: closed db index /var/lib/rpm/Packages D: closed db environment /var/lib/rpm/Packages D: opening db environment /var/lib/rpm/Packages joinenv D: opening db index /var/lib/rpm/Packages create mode=0x42 D: mounted filesystems: D: i dev bsize bavail iavail mount point D: 0 0x00000307 1024 287812 167116 / D: 1 0x00000003 4096 0 -1 /proc D: 2 0x00000000 4096 0 -1 /sys D: 3 0x0000000a 4096 0 -1 /dev/pts D: 4 0x00000011 4096 64439 64438 /dev/shm D: 5 0x0000030c 1024 135546 99333 /home D: 6 0x0000030b 1024 397619 131519 /tmp D: 7 0x00000308 4096 260065 1462823 /usr D: 8 0x0000030a 4096 157409 285427 /var D: 9 0x00000013 4096 0 -1 /proc/sys/fs/binfmt_misc D: 10 0x00000014 4096 0 -1 /var/lib/nfs/rpc_pipefs D: 11 0x00000015 4096 0 -1 /net D: sanity checking 4 elements D: running pre-transaction scripts D: computing 24608 file fingerprints D: computing file dispositions D: opening db index /var/lib/rpm/Basenames create mode=0x42 Killed It hanged after the last step and I had to kill it.

Are the actions the same with cpu usage? There is an option to run rpm in rescue mode by issuing some parameter to reference the root in terms where rpm from the rescue CD is used and rpm removal/addition is performed in reference to /mnt/sysimage. I believe it was used successfully when some had problems with i386 arch packages were installed instead of the proper i686 rpms. The documentation is scarce for rescue mode and rpm. I found RHL 7.2, 9 and RHEL4 The link is for RHEL4 which should be close to current information anyway. <a href="http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/s1-rescuemode-boot.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/s1-rescuemode-boot.html </a> If the rescue mode link does not help, how are others who upgraded from FC4 to FC5T3 systems reacting? Rawhide after FC5T3 was released installs go backwards and replace later version installed packages. I am wondering if this same personality for the installer is effecting FC4 to FC5T3 upgrades also. Major libraries were involved. FC5T1 through rawhide, then to FC5T3 install disc bug. (not supported, but may happen for FC4 or similar supported paths. <a href="https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=183153" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=183153</a> Jim -- Well fix that in the next (upgrade, update, patch release, service pack). -- fedora-test-list mailing list <a href="mailto:fedora-test-list@redhat.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">fedora-test-list@redhat.com</a> To unsubscribe: <a href="https://www.redhat.com/mailman/listinfo/fedora-test-list" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> https://www.redhat.com/mailman/listinfo/fedora-test-list </a> </blockquote></div>
