pvremove fails on mac mini re-install
Last modified: 2007-11-30 17:11:40 EST
Description of problem:
I'm pretty sure I've seen this before, but can't find the bug report if I made
one. I'm installing FC6T2 on a ppc mac mini that had FC5 (I think) on it
already. Selected wipe linux partitions during install. It's now hung on
"pvremove -ff /dev/hda8".

Syslog from install
pvremove should not hang.
Please add -vvvv to the lvm command that is apparently hanging and send me the
output. Or run it under strace. Or 'dd' the first 200k of *all* your
partitions at this point so we can attempt to reproduce it elsewhere.
As I've said before, it would be useful if there was an anaconda debug mode that
would capture the -vvvv debug logs from lvm commands.

mbr and first 200k of each partition
Okay, I'm not sure this is (entirely) a lvm problem, though it may have messed
things up earlier (altough think this was a working FC5 system previously).
Looking in the anaconda log:
20:31:00 INFO : pv is /dev/hda7 in vg rootvg, size is 25439
20:31:00 INFO : pv is /dev/hda8 in vg rootvg, size is 77
20:31:00 INFO : vg rootvg, size is 71456, pesize is 32768
20:31:00 INFO : vg rootvg, size is 25408, pesize is 32768
20:31:00 ERROR : Volume group rootvg using non-existent partition /dev/hda8
and indeed, while the kernel syslog seems to indicate 8 partitions:
<6> hda: [mac] hda1 hda2 hda3 hda4 hda5 hda6 hda7 hda8
parted shows only 7:
Disk /dev/hda: 80.0GB
Sector size (logical/physical): 512B/512B
Partition Table: mac
Number Start End Size File system Name Flags
1 0.51kB 32.8kB 32.3kB primary
2 32.8kB 1081kB 1049kB hfs primary boot
6 1081kB 53.5MB 52.4MB ext3 primary
3 134MB 26.7GB 26.5GB hfs+ primary
4 26.7GB 26.7GB 8913kB hfs+ primary
5 26.7GB 53.4GB 26.7GB primary
7 53.4GB 80.0GB 26.7GB primary lvm
- something is incorrectly reporting 8 partitions and saying that rootvg is
- or parted is incorrectly reporting only 7 partitions? I was able to read
from /dev/hda8 with dd.
- In any case, pmvremove -ff /dev/hda8 shouldn't hang. Don't know how to run
under strace or -vvvv during install. Killed the hung pvremove with kill -9
and it can run okay now.
I've attached the mbr and first 200k of each partition
I can't reproduce this with a FC6T2 install on top of an existing FC6T2 install.
I may try again with FC5...
One thing I noticed while investigating another bug was that pvremove isn't run
with the '-y' argument as it should be. (Still shouldn't hang of course.)
Fedora Core 5 and Fedora Core 6 are, as we're sure you've noticed, no longer
test releases. We're cleaning up the bug database and making sure important bug
reports filed against these test releases don't get lost. It would be helpful if
you could test this issue with a released version of Fedora or with the latest
development / test release. Thanks for your help and for your patience.
[This is a bulk message for all open FC5/FC6 test release bugs. I'm adding
myself to the CC list for each bug, so I'll see any comments you make after this
and do my best to make sure every issue gets proper attention.]
