Why you might want to factory reset a x86 ReadyNAS

June 22nd, 2011 — 7:50pm

A factory reset  wipes all data, settings, everything. So obviously it’s quite time consuming as you need to backup all data on the ReadyNAS first, backup the system configuration should you wish to restore it, then do a factory reset, restore configuration backup and restore data from backup.

However, there are multiple reasons why one might want to factory reset a x86 ReadyNAS (e.g. NVX, Ultra, Ultra Plus, Pro, 1500, 2100, 3200, 3100 and 4200):

  1. Sometimes when troubleshooting a problem e.g. a performance issue, a factory reset can be necessary to help isolate the cause of the problem. This would be one of the last things to try after exhausting other options first.
  2. A factory reset after updating to the latest firmware gives you a clean setup on the latest firmware. This would mean that in some ways your ReadyNAS would be in a better condition than when it left the factory!
  3. A factory  reset can be much faster than expanding your X-RAID2 volume particularly when using high capacity disks.
  4. You cannot reduce the number of disks and expand your X-RAID2 volume i.e. if you have 4x1TB disks installed you can expand to have a volume of 4x2TB disks, but you cannot expand to have a volume of 3x2TB disks.
  5. You cannot add smaller capacity disks and expand your X-RAID2 volume e.g. if you have a 6-bay x86 ReadyNAS with 4x2TB disks installed you cannot expand your volume by adding 1TB disks. Smaller capacity disks must be added first.
  6. On x86 ReadyNAS, some, but not all Flex-RAID volumes can be expanded. You may wish to do a factory reset if you cannot expand your existing volumes.
  7. The reason we all hope we never have: You’ve had multiple disk failures and had catastrophic data loss. You’ve contacted tech support for assistance, they’ve confirmed this and repairing one of your disks for data recovery has not been possible. Disks can and do fail at any time, so it is recommend that you backup important data primarily stored on the ReadyNAS regularly. See Preventing Catastrophic Data Loss
  8. Unfortunately some benefits cannot be obtained without a factory reset.
  9. Unfortunately some expansion limitations cannot be overcome without a factory reset. You can seek advice as to whether you are affected by any expansion limitations by posting on the ReadyNAS forums or contacting NetGear technical support

Why you might want to factory reset a Sparc ReadyNAS

June 22nd, 2011 — 5:54pm

A factory reset  wipes all data, settings, everything. So obviously it’s quite time consuming as you need to backup all data on the ReadyNAS first, backup the system configuration should you wish to restore it, then do a factory reset, restore configuration backup and restore data from backup.

However, there are multiple reasons why one might want to factory reset a Sparc ReadyNAS (e.g. Duo, NV, NV+, X6, Repertoire, 1000s, 600, 1100):

  1. Sometimes when troubleshooting a problem e.g. a performance issue, a factory reset can be necessary to help isolate the cause of the problem. This would be one of the last things to try after exhausting other options first.
  2. A factory reset after updating to the latest firmware gives you a clean setup on the latest firmware. This would mean that in some ways your ReadyNAS would be in a better condition than when it left the factory!
  3. A factory  reset can be much faster than expanding your X-RAID volume particularly when using high capacity disks.
  4. You cannot reduce the number of disks and expand your X-RAID volume i.e. if you have 4x1TB disks installed you can expand to have a volume of 4x2TB disks, but you cannot expand to have a volume of 3x2TB disks.
  5. You cannot add smaller capacity disks and expand your X-RAID volume e.g. if you have a 4-bay Sparc ReadyNAS with 2x2TB disks installed you cannot expand your volume by adding 1TB disks. Smaller capacity disks must be added first. However as X-RAID uses the capacity of the smallest disk you probably wouldn’t want to add a smaller capacity disk to a ReadyNAS array anyway even if it were possible.
  6. On Sparc ReadyNAS, Flex-RAID volumes cannot be expanded. Using Flex-RAID you can have multiple volumes (up to four, with any given disk being included in these) but you may prefer the simplicity of having a single volume or you may already have the maximum number of volumes and be unable to add additional volumes to utilise additional space from higher capacity disks.
  7. The reason we all hope we never have: You’ve had multiple disk failures and had catastrophic data loss. You’ve contacted tech support for assistance, they’ve confirmed this and repairing one of your disks for data recovery has not been possible.

What to do before expanding your ReadyNAS volume

June 22nd, 2011 — 12:47am

One of the great things about the ReadyNAS line is automatic expansion using X-RAID. Both X-RAID (found on Sparc ReadyNAS such as the Duo and NV+) and the newer X-RAID2 (found on x86 ReadyNAS e.g. NVX, Ultra, Ultra Plus, Pro, 1500, 2100, 3200, 3100 and 4200) are major selling points of the ReadyNAS line. Now some Flex-RAID volumes can be expanded on x86 ReadyNAS as of RAIDiator 4.2.16, but this is not automatic. The ability to easily expand your existing volume rather than needing to backup your data, do a factory reset, then restore from backup to get more capacity is a great feature.

You may wonder, surely it can’t be as simple as following the advice in the links I gave above to expand a ReadyNAS volume? Well, it is.

However there are some additional steps one should take if possible before embarking on the process of expanding one’s volume.
