Description Karsten Hopp 2006-03-08 16:34:29 UTC
Description of problem:
anaconda-11.0.1-1 tracebacked during an installation on an OpenPower-720
machine. I'm using vscsi to an AIX host, the logical volumes have been newly
created.

Logfile attached...

Manoj - can you replicate this with a box with AIX VIO here? 
Karten:

How did you create the vscsi devices?

If you switch to tty2 can you get parted /dev/sda print, if you just create a
blank partition on the vscsi drive without any volumes does it work?  Are there
any AIX error messages on the VIO server? 

Notes to self:

Is this suspect from lvm:

Comment 3 Karsten Hopp 2006-03-08 16:54:19 UTC
I've created the logical volumes in AIX with
'mklv -lv vdisk0 client_rootvg 10G'
and bound them with 'mkvdev -vdev vdisk0 -vadapter vhost0 -dev vtscsi0' to the
virtual adapter vtscsi0

client_rootvg is an AIX volumegroup with 7 physical disks

How can I switch to tty2 ? I'm running anaconda inside a vterm on the HMC and
have no idea if there are other means to do that.

Comment 4 Jeremy Katz 2006-03-08 18:22:33 UTC
Although you might hit other problems later (the read errors do generally mean
something else odd is going on), I went ahead and committed a change to catch
the read error in the fs checking code

Comment 5 Karsten Hopp 2006-03-09 11:17:09 UTC
Now I get the usual "The partition table on device sda was unreadable..... Would
you like to initialize this drine, erasing all data ?"

It tracebacked later now, not sure when as I didn't pay attention.
I'll attach the new log.

A restart of the installation after that last traceback worked fine, though. 
It looks like there is another error condition which needs to be caught by anaconda.

Comment 7 Jeremy Katz 2006-03-09 16:08:47 UTC
lvm is trying to read and getting read errors.  Given that it's a command line
utility with no library interface, we really can't do much other than "this failed"

But it's hitting exactly the same sort of errors reading which is either a
hardware problem or a vscsi problem (could be the AIX server or the driver on
the Linux side, but I'd lean slightly towards the server piece since it is very
fragile in my experience)
