I did a very stupid thing and upgraded Debian installed on the device. After reboot I completely lost the access to it: no ssh, no Web UI,… I can ping it and the green light is up, so OS is up. I tried reset button but all it did was setting IP address to automatic.
My main concern is how to rescue my data. If there was just one disk I would just plug it into my motherboard and make the backup, but the problem is that disks are paired into RAID 0 configuration. I don’t have experience with RAID arrays, so any advice on how to rescue my data would be highly appreciated.
Thanks in advance
