Adding Disks to ReadyNAS 316 Questions
Hi! Just purchased the RN316 to replace my failing WD4000X system. I purchased one WD 4TB Red drive and installed that into the new RN316 and have the unit configured the way I want it and data cop...
StephenB,
Thank you for your response, this is helpful information. My current disk configuration is "JBOD" since I only have one 4 TB drive installed. Does this change anything about what you said in your previous post? What would happen if I install one of the 2 TB drives into the NAS? Would it reject it since it's smaller than the previous (and only) drive installed? Have you also had any experience with adding drives that have been previously used being cleaned using diskpart before insertion?
I'm not against doing the factory default, just makes me nervous since things are working well right now.
Thanks again for your time!

If does change some things.
With only one disk installed, XRAID would use a second 4 TB disk for redundancy (giving you a RAID-1 mirror). You'd need to add two 4 TB drives to gain space.
If you do a factory reset with 4x2TB+4TB, you'd end up with an 8 TB redundant volume - this wastes 2 TB of space on the 4 TB drive, which would be automatically reclaimed by either upgrading a 2 TB drive to 4 TB or by adding a 4 TB drive to the final bay. The XRAID capacity rule is "sum the disks and subtract the largest).
Also, the last option would require you to create a RAID-0 group and not RAID-5. That's a bad idea, since if any drives fail, you would lose the entire volume.
One path that I think will work is
- switch to flexraid (note that you are in XRAID if you see a green bar on the XRAID button on the volume tab).
- insert the four 2 TB drives, format each (via the volume page) and create a RAID-5 volume.
- Create temporary share names on the new volume, and migrate your data to the new volume using Frontview backup jobs.
- Destroy the existing volume, and change the temporary share names to match the original. Remove the 4 TB drive.
- switch back to XRAID
- reinsert the 4 TB drive. You might need to format it, but it should then be added to the existing array.
Again, thank you, this is very helpful information. I got all my data backed up off my old WD4000X NAS and have it on a USB external drive. I went ahead and pulled the trigger and did the factory reset and added all new drives allowing it to format and create the X-RAID with the 5 total drive. You are correct, I now have 8 TB total storage space. I was also able to successfully restore my configuration and I'm just starting to restore data to their respective folders.
When it comes time to upgrade the 2 TB drives, can you just "pop" them out and install a new larger drive without telling the system you are doing it? I think this is one of the features of the X-RAID configuration? My plan is to replace all the 2 TB drives eventually and add a final 4 TB to the remaining slot.
Thanks again for all your help today, it is appreciated!

Yes. The NAS supports hot-swapping, so you'd remove the disk and insert the new one with the NAS running. You do need to be careful to wait for the resync to complete before you move on to the next disk. You can use the NAS during the resync, though the performance will slow down.
The first upgrade should prompt for a reboot - which is needed to trigger the volume expansion. After that there will be an additional resync. What's happening underneath is that a new RAID group is being added to the volume so you can use the 2 TB of space on the 4 TB drive that right now can't be used. The following upgrades won't need that reboot step.
The volume is vulnerable to failure during resyncs, because RAID redundancy is lost until the volume is fully rebuilt. So I do suggest making sure your backup is up to date before you begin. RAID does help protect your data, but it really isn't enough - the only way to do that is to maintain at least one backup on another device. Personally I like at least three copies (including the original) of anything I care about.
StephenB, thank you for confirming the steps needed to upgrade the drive(s). I am an experienced IT professional, just not familiar with this device or how the X-RAID works, so thank you for that information.
As for backups, I've always kept my data in multiple places. Backups for my backups, for my backups! LOL!!! My WD4000X was running Windows Storage Server and I had CrashPlan running on it. I paid to use their cloud backup and I also ran a backup to my parent's house on mom's computer, but I'm sure as you know that is going away later this year. My subscription was up in August, but with my WD4000X NIC's dying earlier than expected, I had to make the jump. I'm trying to avoid having my data in someone else's' cloud, so here is my question to you since I've tried Googling it and cannot find an answer. I have a Nighthawk R7000 installed at my parent's place. If I plug in an external USB drive on it and setup ReadyShare and add it to my ReadyCloud account, is there a way to use that as my "Cloud" backup location from the RN316 to it automatically? Perhaps RSync? Just wondering if you have any experience in this area.
I'm also working to understand the Network and File share settings on the RN316. Do you know if there is a tutorial anywhere that explains how this works? I understand the architecture of Active Directory but find this somewhat confusing. I've read the Netgear guides, but they don't seem to help either. Any guidance you can provide is again appreciated.
Thank you!
