...to know if the existing data on the orignal 40GB drive in the system will be destroyed when I create the raid with mdadm. Also do the 2 drives after being setup with mdadm have to be reformated? Both the 40GB drives are now formated with ext3. If not, will the added 40GB drive assigned to the Raid1 atomaticly sync to the original 40GB drive.

Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generated in /var/xen/dump (on Domain0).
