[Bug 1541510] Re: parted crashes on lvm, on a dasd drive

Then I'd say that the bug is actually in the kernel: it should *not* be passing down the dasd partition manipulation ioctls. Patching parted to ignore it based on GETGEO works around the problem and stops parted from crashing, but ultimately, you do not want to allow any partitioning tool to mess

[Bug 1541510] Re: parted crashes on lvm, on a dasd drive

Why does it even try to activate the dasd code on a logical volume? It shouldn't be doing that at all as it should not know or care that the logical volume is built on top of a dasd disk. Unless... iirc there was some special ioctl that dasd disks have and that is how parted knows it is dasd...

[Bug 1541510] Re: parted crashes on lvm, on a dasd drive

The parted code is iterating all the label types and consequently is probing for DASD. The weird thing is that on one hand the DASD ioctl is passed down to the physical volume (and I mean weird: what would have happened if the logical volume was realised by extents on both DASD and SCSI disks?)

You might want to try out this patch which worked for me. I was able to partition the logical volume on top of a DASD PV. If this solves the problem in the installer I can follow up with upstream. ** Patch added: "0001-fdasd.c-Safeguard-against-geometry-misprobing.patch"

Maybe try bailing out of fdasd_set_geometry if HDIO_GETGEO returns 0 for sectors or heads; then the probing logic should move onto other labels, since this isn't really a DASD anyway. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

I think you're going to see the same thing upstream The more generic _device_probe_geometry has explicit checks for getting non-zero sectors and heads back from HDIO_GETGEO and if it doesn't get them it uses defaults But fdasd_get_geometry doesn't have quite the same checks around its use of
