Hi All, Sorry for the so many questions but still manual may not always answer to them.
I actually mounted 2 usb pens in RAID 1 in order to understand how it works. When one is removed the RAID device properly works. When remounted I keep having the device offline. $ sudo bioctl -i sd2 Volume Status Size Device softraid0 0 Degraded 509894144 sd2 RAID1 0 Offline 509894144 0:0.0 noencl <sd0a> 1 Online 1011636224 0:1.0 noencl <sd1a> How do we make the device become online again ? BTW does the same apply for physical drives instead of usb pens ? Thank you.
