Hi,
FYI -
a) CentOS version 6.0.
b) Software RAID.
c) Existing Software RAID 1 (mirror) mount point only md0 and md1 (/).
d) Managed to find information from following web page.
http://tcpdump.com/kb/os/linux/remov...d-devices.html
e) Able to umount md0 not for md1 even had tried to kill process or fuser.
f) Error message - device busy.
Reason: Migrate Physical Linux Server to Virtual Server (WMware vSphere 5.) using VMware P2V product(only certify for Linux and Windows).
The best patrice for VMware ESXi and Windows Virtual Server always using SAN/ DAS/ NAS with either RAID 1/ RAID 10/ RAID 5.
As for VMware could not recognize software RAID for Linux except Windows working perfect.
Please advice is there any work around method to remove software RAID or similar function from Oracle Solaris (snapshort)
Thank you.
Regards,
Wang Chen Yung
