Red Hat Bugzilla – Bug 240742
clearpart -all also removes partitions on external devices
Last modified: 2016-02-17 19:01:49 EST
Description of problem:
While installing RHEL5 using a kickstart file that contained a 'clearpart --all'
entry, I was somewhat dismayed to discover that the external USB disk I had
forgotten to disconnect.
Now technically it doing the right thing - it is doing what I actually asked it
to do. However, I feel that blowing away external devices is somewhat unexpected
behaviour - it feels decidedly unsafe.
Steps to Reproduce:
1. Attach a USB disk (might also work with other external devices such as SANs
and USB keys) to machine
2. Install using a kickstart file that contains the line 'clearpart --all'
Wave byebye to all data on external drive
As it is an external drive I would expect it to, by default, not touch it. An
explicit flag --external or somesuch would be nice.
We also will install to external drives.
If you don't want external drives to be considered at all, add 'nousbstorage' to
your boot command line and we won't ever load the module. You can also specify
specific disks to clear with --drives= on your clearpart line or add drives to
be explicitly ignored with ignoredrive.
Agreed it is not a bug, and I am aware of the various options that can be passed
to the kernel and installer. However, IMHO the default should be the other way
round, as it is far more likely that somebody will have external storage
connected that they don't wish to install to/blow away: Defaulting to an
accidental data loss situation just seems... wrong.
But maybe that's just me :)
