Description Richard W.M. Jones 2013-02-11 21:08:04 UTC

Description of problem:

If a Windows guest has bad sectors (eg. if it came from a
physical machine) then virt-resize cannot resize it, because
the ntfsresize utility will refuse to run unless the --bad-sectors
option is specified.

We should either detect and add this option automatically (if
that is possible) or we should allow the user to specify this
option.

Version-Release number of selected component (if applicable):

libguestfs 1.21

Or even find a way to teach windows that there are no longer any bad sectors in the copy (perhaps by clearing or deleting the hidden $BadClust file), since the destination file is not the same block device as the source that had bad clusters in the first place.

Comment 2 Eric Blake 2013-02-17 23:25:58 UTC

Looks like 'ntfsfix --clear-bad-sectors /dev/...' is the way to modify the file system to force windows to quit treating sectors as bad.

This product has been discontinued or is no longer tracked in Red Hat Bugzilla.

Comment 4 Alasdair Kergon 2025-10-17 12:52:13 UTC

Reopening because Virtualization Tools has not been discontinued.
