[Pkg-ganeti-devel] Bug#853167: ganeti-instance-debootstrap: OS installations fails because sfdisk believes the disk is in use

[Martin Weinelt]

Package: ganeti-instance-debootstrap
Version: 0.16-1
Severity: important

Dear Maintainer,

as agreed on IRC I'll submit this bug for you to triage.

The OS installation through ganeti-instance-debootstrap fails on
stretch because sfdisk believes that the disk is in use.

I'm using the drbd disk template in a two node cluster.

```
Mon Jan 30 13:01:58 2017 * running the instance OS create scripts...
Failure: command execution error:
Could not add os for instance kirk.chaos.hg.tu-darmstadt.de on node
deimos.darmstadt.ccc.de: OS create script failed (exited with exit code
1), last lines in the log file:
This disk is currently in use - repartitioning is probably a bad idea.
Umount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.

sfdisk: Use the --force flag to overrule all checks.
```

Adding `--force` to the sfdisk call in /usr/share/ganeti/os/debootstrap/common.sh:98
will allow for completion of the os installation.
Adding `--no-reread` didn't change a thing for me.
