From mboxrd@z Thu Jan 1 00:00:00 1970 Message-ID: <3A5E21E6.DE26A121@wanadoo.fr> Date: Thu, 11 Jan 2001 22:13:10 +0100 From: Martin Costabel MIME-Version: 1.0 To: linuxppc-dev@lists.linuxppc.org Subject: pdisk weirdness Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: Having observed for a while that pdisk (linux) doesn't work on my iBook, I tried to understand what is going on. It's weird. Doesn't work means that 'pdisk /dev/hda' (or 'pdisk -l' likewise) gives me the output: pdisk: Can't read block 0 from '/dev/hda' Edit /dev/hda - Command (? for help): p No partition map exists Command (? for help): q Segmentation fault This is pdisk version 0.8a2 (16 May 2000) from the pdisk-0.8-1.ppc.rpm as it is contained in LinuxPPC 2000 and LinuxPPC 2000 Q4 aka Halloween. When I downgrade to the pdisk-0.7-2 RPM from LinuxPPC 1999, it works as it is supposed to. Also I think I remember that the new pdisk works when run with a 2.2 kernel. Only the combination of new pdisk and 2.4 kernel doesn't work. What is weirder is that there is (almost) no source to be found for this pdisk-0.8-1! On the LPPC 2000 source CD, there is no pdisk at all, and in the LPPC 2000 Q4 source directory, there is the SRPM for the old pdisk-0.7-2. I finally found the sources at the defunct dev-rel CVS repository at gate.crashing.org. There is a llseek-patch (by Tom Rini, IIUC) which seems to be the origin of the problem. If I back it out, pdisk works again. Is anyone successfully running pdisk-0.8-1 with kernel 2.4? -- Martin ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
