Howdy. Sorry for the noob question. My first one.

 

I just put two brand new 4TB drives into my server. I'm running Version 5.0-rc5

 

First I replaced the 3TB Parity drive with the brand new 4TB drive. It ran a long time, came up fine, everything hunky dory, no errors in the Errors column, none in the "Last checked..." parity report on the main page.

 

Next I replaced a 2TB data drive with a brand new 4TB drive. It ran a long time, ran very slowly at times, eventually finished, saying "Parity if valid" and "Last checked on Sunday, 2010-01-03, 14:15 (two days ago), finding 0 errors.

* Duration: 13 hours, 15 minutes, 22 seconds. Average speed: 83.8 MB/sec".

 

However, the Errors Column shows 35,568 errors for the new 4TB data drive.

 

All of the other drives have zero in their Errors Column.

 

I did not run Clear on either new disk, as I don't know how (feel free to mock and kick me...).

 

Should I be concerned about this?

 

Should I run clear (if I can figure out how) on the troublesome disk and re-assign it, let parity run again? Or are 35,568 errors on a 4TB no big deal?

 

Thanks for your insight!!!

See v5 help in my sig

trurl - thank you for helping out.

 

I am attaching my syslog. The dates all seem wrong. Perhaps I never set my system date?...

 

I am also attaching a screenshot of my Main page, to show that everything appears to be healthy.

 

But in addition to my original post regarding unexpected Writes Errors (as I was upgrading the size of my UNRAID), it has just come to my attention that most of my data has disappeared 0_o.

 

So, this thread is a continuation of my OP. It includes the syslog you asked for. And a screenshot. And a panicked expansion of the problem that includes a sudden/recent apparent loss of nearly all data.

 

Thank you for any info, troubleshooting, advice you can offer.

 

all the best,

Well, it would have been better to test the drives with preclear, but I guess you could say they have been exercised pretty well at this point, so if we had SMART reports from them that would be almost as good.

 

The syslog mostly just has mover and messages where ntpd couldn't connect to a timeserver. From console or telnet, what do you get with?

ping pool.ntp.org

 

Nothing in the syslog about the errors, but it has rotated so is incomplete. You may have older syslogs in /var/log/ named syslog.1, etc.

 

All drives are green, so it seems unlikely you have lost any data. How are you trying to look at your data? User shares over the network?

telnet-ing to the UNRAID, logging in, issuing "ping pool.ntp.org" results in an "unknown host pool.ntp.org" error message.

 

I do see other logs. "syslog" "syslog1" and "syslog2".

 

I don't know how to get those logs to you from a Windows telnet connection.

 

I am mainly looking at the UNRAID over Windows 8.1 Pro mapped network drives.

 

However when I navigate using telnet to //mnt/disk2/Donna/Photos I see one and only one directory "2011-04-27_Mike+DAnn+Green_Valley_Ranch"

 

I used to have many hundreds of directories in the same naming structure, and at least 1.2 million photos + sidecar files. Nearly 12TB of data.

 

Now I see only 3 photo directories in the Mapped Drives. The one named above from 4 years ago. And two uploaded in the last two days.

 

When navigating with telnet, the three photo directories seem to be spread across my five drives. I've looked in

//mnt/disk1/Donna/Photos

//mnt/disk2/Donna/Photos

//mnt/disk3/Donna/Photos

//mnt/disk4/Donna/Photos

//mnt/disk5/Donna/Photos

and I only see the three directories:

"2011-04-27_Mike+DAnn+Green_Valley_Ranch"

"2015-10-27--Dance Meets Fashion for SPCA-Tommy Wind Theater"

"2015-10-29-Jamey Kirkland-Recipe Showdown-MGM"

 

(different formatting of directory names when looking at them in telnet)

 

Will it help if I run SMART reports? Can you direct me how to pull those syslogs and post them here?

 

I'm totally stumped. Where did 1.2 million files go? Where did 12TB of photography go?

 

Thanks for your help!

The v5 help I directed you to in my sig tells you how to copy syslogs to your flash, and also directs you to getting smart reports. Also, if you have your flash drive shared you should be able to browse it over the network to get those files.

 

On the Main page all the way over to the right there is a View column with folder icons. You can click on them and drill down into the disks.

 

From telnet, what do you get with

ls -lah /mnt/user

Results of ls -lah /mnt/user

Those syslogs look pretty much like the other one, mostly just mover and failed attempts to reach a timeserver. What we are missing is any log that shows bootup, or anything that shows any of your drive swaps.

 

Was all of your data in the Donna share? Or are there supposed to be others?

 

I really don't know how you got to this point. It almost seems like you must have made some mistake when you were swapping drives around. How many data disks did you replace? Do you still have the originals?

 

Did you ever do New Config at some point?

 

Have you tried to get SMART reports for the new drives? That would tell us whether they were trustworthy drives or not, but wouldn't really explain where your data is.

 

If it was only a question of your user shares, I would suggest a restart of the array, or maybe even a reboot. But it looks like the actual disks don't have the data you expect.

 

Some lines in the syslog about duplicate files which also makes me wonder if you haven't made some mistake with your disk swaps and rebuilds. Did you expect the Donna share to be spread across all disks? That's not necessarily unusual, since if you write to user shares unRAID will decide what disk to put them on based on the share settings.

 

Do you have any backups of your important files? unRAID or in fact any system is not really a backup unless it is used to store additional copies of files you have elsewhere. The only thing that counts as a backup of a file is another copy of it somewhere.
