Ticket #148 (assigned defect)

Description

mondorestore is unable to re-create a SW Raid5 with mdadm on RHEL 4 due to the call to mdadm which contains the -p option. Even if that option is documented, there seems to be no way to make it accept the parity option, and thus mondorestore fails. There is a need for a workaround in that case.

The one applied by the person reporting the bug to me was extreme, but kept for reference:
