Upgrade 2150 Readynas Duo to 2 TB drives
I have a Readynas Duo 2150 I purchased a few years ago. It's 500 Gb drive reached 90% full, so I wanted to upgrade the discs. I purchased two seagate drives which were on the approved hardware list.
1. Backed up data from Readynas duo to another computer.
2. Replaced Ch 2 drive with a new 2 tb disk.
3. Readynas made a duplicate partition the same size as the 500 gb disk on the new 2 tb disk, then synchronized and was fully redundant.
4. Replaced drive 1 5oo gig disk with another 2 tb disk.
5. Readynas synchronized it, and had two 460 partitions on my 2 tb drives.
6. Was unable to expand volume after trying every option I could find.
7. removed drives to other computer and wiped them to no partions, unformatted.
8. reinstalled Ch 1 drive 2 tb disk; reset readynas to factory defaults.
9. successful; but frontview volume tab reads 187 gigabytes free on a 1862 gig space?? Odd as I had not added any files to the Readynas.
10 installed 2nd 2 tb drive into the 2nd drive bay; resynchronized.
11. popup message at end of resynchronization says it's now fully redundant. But frontview is a different story: Disk space reads: 542 MB (0%) of 1667 GB used
Configuration is blank, the resynch button is greyed out. Status is blank. Raid disks is blank. Available disks reads ch1 Seagate ST2000DL003-9VT166 [1862 GB] 187 GB free. Ch2 Ch 2 : Seagate ST2000DL003-9VT166 [1862 GB] 1860 GB free. Both are Seagate approved drives on the compatibility list. I have not changed anything else, as everything was working fine, and I used new disks which were on the approved list from when I purchased the Readynas. I still have the original 2 500 gb disks with their information intact.
It does not appear as per frontview that my system is in Raid, because the volumes are so different in size.
I repeated everything twice, with the same result. I still get two different volume sizes on identical drives, no matter which one I install first, so it's not a defective disk problem. They both respond the same to the procedure, and wind up with different volume sizes and no indication that the system is in raid.
Now, is my system in raid x? Why does channel one read 187 gb free when I've added nothing to the Readynas?

- Your firmware (RAIDiator 4.01c1-p2) was the first Duo firmware I believe and released back in 2008. That firmware does not support 2TB drives.
Please do the following:
1. Update to RAIDiator 4.1.8 (http://www.readynas.com/RAIDiator_4_1_8_Notes)
2. Verify update completed successfully
3. Do a factory reset via System > Update > Factory Default in Frontview
Welcome to the forum! - Will do this tonight and let you know results.
Thank you. - Your welcome.
I wouldn't recommend posting the serial number or MAC address of your ReadyNAS on the forum as these uniquely identify your NAS. - Everything seems to be working fine now with the two 2 tb disks. Thank you. for anyone else going through this, be aware that after the factory reset, with the 2, 2 terabyte disks in the NAS, it took nearly 10 hours for the device to format and set up the device until it was finished; the act led and the channel 2 light seemed to go on blinking forever, I was wondering if something was wrong. but I let it run itself, and it worked out fine. Just be patient and it will finish setting itself up.
Thanks for the advice, mdgm. I changed the subject field of the initial post so that this thread information will show up on a google search for others to see. It would have saved me several days of work if I had found it. - Question; I have updated from RAIDiator 4.01c1-p2 [1.00a042] firmware to 4.1.8; there were a few files on the old 500 GB disks that weren't backed up; not really important, but would be nice to have. If I turn off the readynas, unplug it, and put an original 500 GB disk into the same slot it was in, will the new firmware recognise that disk? I have one here, and one off site which I kept as a backup. I didn't know that readynas drives are completely inaccessible on windows computers.
- You should be able to recover the data doing that.
You can read the data off a ReadyNAS disk using a PC: Mounting Sparc-based ReadyNAS Drives in x86-based Linux.
Please note that treating RAID as a backup is a very bad idea. RAID provides redundancy/high-availability. It is not a substitute for backups. Please have a read of Preventing Catastrophic Data Loss
In future I suggest you backup to a USB disk, another NAS or some place else. - "Please note that treating RAID as a backup is a very bad idea."
Yeah, I figured that out now. I thought that by simply taking out a disk and keeping it off site it would be a good backup idea. I had no idea that there was no way I could simply access that disk in anything other than a readynas or linux/sparc machine. Kind of an odd marketing decision I think. I had been recommending a readynas duo to other people thinking they could easily protect their data by simply swapping out a drive and keeping it safe. Now I have the unfortunate responsibility of telling them I was an idiot to assume a company marketing to a populace of 90% windows users that they would make the device use a system that made their back up copies completely incompatible with a windows pc. So, now that I know, how do I re re install the 2 tb disks so I have 4k block sizes instead of the incompatible 16k ones?(just in case!) nightfly wrote: "Please note that treating RAID as a backup is a very bad idea."

You can recover data in a Linux x86 machine or using a special app in Windows.nightfly wrote:

That would be a bad idea with any NAS. RAID is not designed to be treated as a backup. It provides redundancy/high-availability in that if a disk fails you don't need to restore from backup and can continue working and replace the failed disk to restore redundancy. In fact treating RAID as if it were a backup can lead to data loss. When the disk is put back in the NAS it has to be wiped and there is a resync which puts heavy stress on all disks in the NAS. If a disk is failing a resync can finish it off. Not to mention that SATA connectors can be damaged through repeated use. A responsible IT manager wouldn't pull a drive out of a server and take it home and consider it a backup, they'd backup to tape, a USB disk, a NAS or some place else. The same principles apply with a home NAS.nightfly wrote:

You can't. The Duo only ever shipped with RAIDiator 4.x which creates the data volume using the 16k block size. If you really need to read a disk using Windows (e.g. for data recovery) you can use a Windows program referred to in the "Mounting" article (or the comments on that article) I linked to in my previous post.
