Has anybody encountered this problem? I have a box that has FC2 installed. I wanted to trash the FC2 installation and install CentOS 4. I have a pxeboot/dhcp/kickstart environment and so I tried automatic disk partitioning (clear all partitions and then create new ones), manual disk partitioning but everything else is automated and finally, zero automation, just a manual installation through VNC. Once I reach a part that touchs disk, the process will stop and end up with: Traceback (most recent call last): File "/var/tmp/anaconda-10.1.1.13//usr/lib/anaconda/gui.py", line 789, in nextClicked self.dispatch.gotoNext() File "/var/tmp/anaconda-10.1.1.13//usr/lib/anaconda/dispatch.py", line 171, in gotoNext self.moveStep() File "/var/tmp/anaconda-10.1.1.13//usr/lib/anaconda/dispatch.py", line 239, in moveStep rc = apply(func, self.bindArgs(args)) File "/var/tmp/anaconda-10.1.1.13//usr/lib/anaconda/partitioning.py", line 54, in partitionObjectsInitialize partitions.setFromDisk(diskset) File "/var/tmp/anaconda-10.1.1.13//usr/lib/anaconda/partitions.py", line 140, in setFromDisk diskset.startAllRaid() File "/var/tmp/anaconda-10.1.1.13//usr/lib/anaconda/partedUtils.py", line 542, in startAllRaid DiskSet.mdList.extend(raid.startAllRaid(driveList)) File "/var/tmp/anaconda-10.1.1.13//usr/lib/anaconda/raid.py", line 106, in startAllRaid mdList = scanForRaid(driveList) File "/var/tmp/anaconda-10.1.1.13//usr/lib/anaconda/raid.py", line 56, in scanForRaid (major, minor, raidSet, level, nrDisks, totalDisks, mdMinor) =\ File "/usr/lib/anaconda/isys.py", line 97, in raidsb return raidsbFromDevice("/tmp/md") File "/usr/lib/anaconda/isys.py", line 103, in raidsbFromDevice rc = _isys.getraidsb(fd) SystemError: (5, 'Input/output error')
