Hello,
Our HP Netserver has three 4.26GB disks of which only one is used
presently. After acquiring a Mylex Acceleraid170 I thought it might be
possible to:
- install the controller with all three disks plugged into it;
- define the first disk (on which lives our present root partition under
Debian/Linux) as a non-RAID disk (JBOD in Mylex-speak?);
- make sure the Mylex controller leaves alone our boot disk while
allowing us to boot from it;
- (alternatively leave this first disk on the SCSI controller)
- configure a degraded RAID5 partition on the remaining two drives;
- reboot the machine from the first (intact) disk;
- copy the whole root filesystem to the degraded RAID5 partition;
- boot from the degraded partition and check all is OK;
- add the original first (boot) disk to the RAID5 partition for rebuild;
In the process of implementing some of these steps two questions have
occurred:
1) is it safe to let the Mylex controller temporarily manage our boot
disk as a single, non-RAID drive? Will the EZ-Assist configuration
destroy any and all data even when selecting single-drive mode (JBOD)?
2) apparently is isn't possible to configure a RAID5 partition on two
disks in the EZ-Assist menu? There is no option to build an initial
degraded partition. Is there a workaround?
I couldn't find any answer in the Mylex docs.
Thanks in advance for any suggestions,
