RN102 - Raid 1 vs X Raid and recovery
Hello, thanx for you help. I have been a ReadyNas owner and user for a long time... now setting up a RN102 with two 3 TB drives for a friend and this is my first experience with a two drive system. The system will be a music and picture server.
1 - Is X Raid really Raid 1 in a two-drive system; are the two drives mirrors of each other?
2 - If I have a chassis failure, can I install one of these drives directly into a PC? My assumption would be the drives are simply mirrored data, nothing fancy stripped across and can therefore be read by PC.
The reason I am concerned about this is backing up this two drive system. I have had a ReadyNAS chassis fail and lost my data (ReadyNAS NV+, X-Raid 5); no issues, as I had this unit backed up. If these are just simple mirrored drives, then maybe I can install them into a PC given a chassis failure.
Just curious. Thanx again.
Peace

- The drives are mirrored however it is using md raid and BTRFS. The array can easily be mounted using a Linux machine with a recent kernel, mdadm and btrfs-progs installed.
The potential for chassis failure is not the only reason to backup data. Don't rely on being able to remove drives, hook up to PC and recover data that way.
For your Sparc X-RAID array you could have used an ordinary x86 Linux machine and tried the instructions here: http://home.bott.ca/webserver/?p=306
Apart from chassis failure there are other possible problems e.g. fire, flood, theft, multiple disk failures etc. Backups are important.
