I got finished with a series of (3) drive conversions from ReiserFS to xfs several days ago.
I did a bit of musical chairs with drives and also used this opportunity to replace one of ReiserFS drives with a larger one to get all this done.
All this was done using the documentation I found here in the forums. Many thanks for the well written docs.
No problems with the conversions, essentially it was parity check, rsync, parity check, and move drives around as needed. 5-6 days total per drive or so. I understand the second parity check for each drive conversion wasn't needed but I did it anyway. And i wasn't in a hurry. All parity runs were clean.
I had (3) 6TB drives with ReiserFS (plus other xfs drives). Bought an 8tb drive. Did the first conversion going from 6TB to the new 8TB. Took that pulled 6TB, cleared it and then converted/changed out the second 6TB. Rinse and repeat for the third drive.
The final 6TB drive is sitting on the shelf as a spare.
All was fine until I started an additional parity check to finish up everything and button it up. It started spewing millions of sync errors on the new 8TB drive. I had several clean parity checks with this new drive installed before this one final pass.
I stopped, shutdown, checked all cabling, ran extended SMART on all drives and they are clean.
Did the filesystem check on the suspect drive but the pass with -n didn't show anything.
restarted parity check yesterday and the sync errors are back on the same new 8TB drive.
8 million and some change errors corrected so far but no change in the count for 3-4 hours.
the current parity check run is 19 hours into a probable 26 hour run.
Looked around on the forums but I'm not really seeing a clear consensus on the next steps.
any suggestions on my next steps?
FYI, I've been using Unraid for about 10 years. On my third hardware build right now.
Love the product!!

I'm in the same situation with needing to convert some drives from reiserfs to xfs.
I've been studying the wiki and i'm confused about the unRaid versions mentioned in the doc.
it's mentioning v6.2.
I thought the latest version was 6.11

Time to increase space and I also discovered a smaller drive just went out of warranty (3yr).
So I'll yank the old drive and drop in a larger new one.
The only difference I can see between the Plus and Pro is the warranty.
Otherwise they seem to be the same.
The Plus looks like 3 years and the Pro is 5 years.
For a 10gb drive I'm not seeing the point of a $50-60 difference.
Am I missing something?

Thank you @trurl, I have 0 experience with UnRaid and I did not know that. Does it means that I need a USB key always attached to my machine?
You can get a short pigtail going from your USB pins on the MB to a single USB port. Then you can plug the USB drive into the pigtail and then tuck it safely out of the way inside the case somewhere.
That's what I did when i built my system a few years ago.

Back about ten years ago, I decided I had a storage space problem.
So I looked around to see what was available. I don't remember what was around at the time but I came across the unRAID product.
So you load something on an USB and then boot to it and it then sees all the attached drives. Create shares, add data and you're good. It has data recovery as well in case of drive failure. Sounded pretty much agnostic as far as motherboard hardware was concerned.
Interesting concept. And an online community with all kinds of info.
Like any IT guy with 20+ years of hardware experience I had accumulated assorted old/unused small drives and out of date motherboards.
Let me slap together something as a proof of concept thing real quick and see what happens.
This was just as SATA was coming out. But my old boards only had IDE Master/Slave stuff. It was just stuff I had laying around.
Got four assorted drives of unknown heritage from the junk box and stuffed them into an old case. Made the bootable USB and fired the whole mess up.
Got the web console up and poked around. Yea, all the drives were listed. OK, biggest drive will be parity and the assorted leftovers will be drive space. I liked that idea because you could use what you had on hand, they didn't need to be the same size. Probably had a total of less than one TB of drive space scattered across the entire box.
UnRAID got done prepping all the space and I set up some shares and copied test files to them. That was pretty straight forward.
So I let it run a few days as I went on to other stuff in life.
I brought the console up a few days later and saw that I had a drive failure. The drives did come from the junk box so that was sorta expected.
Ok, let's see how this data protection things works. The shares were still there and so was the data. The parity drive was doing it's job. Nice.
That's working as advertised.
Almost got me sold at this point.
Back to the online community and the assorted FAQ's. How do you recover the drive/data?
Shut down, pull bad drive and insert another drive of same or larger size.
Click a few buttons and the system kicks in and the data recovery begins and then new drive is repopulated with data.
Only downtime was swapping out hardware. From the user point of view I couldn't tell anything was going on in the background as the data was being recovered.
Ok, I'm sold. Take my money now.
Bought a couple keys and a pair of USB drives in September of 2011. Don't remember for sure but I think they had a sale or something going at the time.
I'm on my second specially built production server now.
Got the second USB on the test box. it's just just an old desktop stuffed with the smaller drives I have pulled from the production box as I upsize it.
23 TB scattered across 8 drives with Plex running on the SSD.
Yes, I'm happy with the product.

in reference to these errors you are getting "Machine Check Errors "MCE Error"
i'm getting them as well, "NAS-1 kernel: mce: [Hardware Error]: Machine check events logged'
I flashed the BIOS to the newest one i could find on the Asus site before i loaded unRAID, i think the version was 2002.
next time i reboot i'll make a point of checking that.
flashing your BIOS might not help that.

no problem, i went ahead and ordered some stuff.
i got basically the same setup coming in.
i went a little more on the cpu and memory though.
i'll go ahead and run it with my extra usb key and some spare drives to break it in then carefully transfer the drives from my old box
as they say, some assembly may be required....

i'm really tempted to build one just like it myself.
i have an old one running 4.7 and it's time for a hardware and software refresh
i saw on other sites where people had mentioned that the power supply in that case was a tight fit.
i'll need to watch out for that.
anything else i might need to keep an eye on?

You have any current photos?
And how is it going so far?
Unraid v 6.11.5 Sync errors on Parity Check after ReiserFS to xfs conversion
in General Support
Posted
the last parity check that was running finished with no additional errors and I ran another one and it finished with no errors.
I'll run another couple of checks over the next week or so to see what happens.
