Upgraded 5.06->6.2.4, no Web GUI

[Electric]

I upgraded my 5.0.6 install to 6.2.4 (latest stable version).  I did not go through any intermediate releases.  I have a Pro license.

 

The system boots and I can telnet into it.

 

I cannot access the web administration interface.  Have tried both Safari and Firefox on my Mac.

 

Can anyone recommend next steps?

Try booting into Safe mode from the boot menu and see if that work OK.

 

This will boot the system with no additional plugins.  If that works then you may have some plugins that are incompatible with 6.2.4 left over from your 5.0.6 setup.

When I boot in safe mode, it appears to hang at rcsyslogd initialization.  See attached screenshot.  Configuration files are in the attached zip files.

By any chance have you made any changes/additions to the config/go file on your flash drive?

I don't think so.  My go file is 71 bytes, per upgrade instructions.  I updated post #3 in this thread with my config files, in case anyone can see anything wrong with them.

 

I very much appreciate your help, by the way.

We could go through a ton of diagnostics, etc but at the end of the day its going to be easier to

 

- Set up a new stick with unRaid and see if it boots properly.

- If it does, on the original stick go back to v5 (hopefully you made a backup), and make a note of your drive assignments.

- copy the .key file from the flash drive somewhere safe (should be in the config folder)

- reformat and set up v6

- copy the .key file back into the config folder

 

Boot up v6 and reassign your drives

 

(This is basically the clean install (without copying over any potential problems from existing config files) directions from http://lime-technology.com/wiki/index.php/Upgrading_to_UnRAID_v6)

Also after doing what Squid suggests, if you are still having the same problem run the command 'diagnostics' from your telnet session and post the resulting file for people to use to help diagnose the problem.

Thanks for the suggestions.  I loaded unRAID 6 onto a new USB key.  It booted and I could telnet into it.  I could not access the web interface, however.  I ran the diagnostics script and it completed successfully; if I can figure out how to upload it here I will.  I tried ftp but could not start a session.  It does not seem to be stored on the USB key itself.

 

I have reloaded unRAID 5 onto my registered USB key.  I am now doing a parity check which will take about a day, in an effort to make sure that everything is in order for the eventual migration to unRAID 6.

 

I am going to buy the largest external drive I can find, and back up as much important data as I can, as the migration to unRAID 6 does not seem to be straightforward for me.

Read this upgrade WIKI:

 

    http://lime-technology.com/wiki/index.php/Upgrading_to_UnRAID_v6

 

There is a link to a quick guide near the top but this WIKI covers about every problem that the hundreds of updaters have encountered moving to version 6.X.  (And many hundreds more made the jump after reading the WIKI without any problems.)

[Electric]

Thanks Frank.  Read it several times but it does not seem to help with the particular problem I am having.  Are you aware of anything specific in that document that covers everything working except the web UI?  Thanks for posting any section I might have missed.

 

I can appreciate that many people have had a flawless upgrade experience.  But I didn't ask for these problems; I can think of much better ways to spend my weekend.

Can you tell us about your hardware? How much RAM? Did you find the diagnostics file in the logs folder on your USB flash device?

 

[garycase]

At the selection menu for UnRAID, MemTest, or UnRAID GUI Mode, try booting to GUI mode.

 

Some folks have had an issue with certain hardware combinations where the "normal" mode doesn't work; but the GUI mode works fine -- even though you're not actually going to use the GUI on the console.

Nothing about the upgrade should put any of your data at risk, but you should have already had backups of important data whether or not you ever upgrade.

I am not sure I will be able to read that filesystem without a copy of UnRAID that has a working web UI.  The data seem to be stored across several drives in a very proprietary way.  Even if I can mount the drives on a regular Linux box (can I?), I'd lose the correction codes. So the risk is not zero.  It was very exciting for me when I reinstalled UnRAID 5 onto that USB key to see if I could read the data again.

 

The UnRAID box IS the backup for all the computers in the house.  I am hoping that the combined probability of a desktop/laptop drive failing, and the UnRAID storage also failing at the same time, is incredible.  If I couldn't get the UnRAID 5 box working again, I would have burned another weekend backing everything up onto some other backup system like FreeNAS that I don't have time to learn right now.

 

To answer the question about the hardware, it is a 64-bit AMD CPU in a 24-bay SuperMicro case. It has 8 GB of non-ECC RAM. It has about seven drives in it right now, including a 256 GB SSD cache drive.  It has been running UnRAID 5 more or less since that version came out.  Has been rock-stable; I spend almost no time administering it.  I think UnRAID is fantastic.

Already tried it.  Didn't seem to help.  Thanks though. I am grateful for all suggestions.

Each disk in unRAID is independent and can be read without the others. V5 uses a less popular Linux filesystem that can't be directly read from Windows for example, but can be read on Linux and still works fine on unRAID 6.

 

Each file is completely contained on a single disk, but unRAID allows you to spread folders (user shares) across disks. The "correction codes" (parity) are not necessary for reading a disk and its files.

What you seem to be saying is that I would have to reconstruct the share by consolidating files from up to seven disks.  Even if that's possible, it sounds like a hassle and not anything I want to get into.

 

The "correction codes" (parity) are not necessary for reading a disk and its files.

 

That's only true if there are no errors on the disk.  If the Hamming codes (or similar codes) are not present, the data cannot ever be recovered if the disk has a bad sector.  And the odds of having a bad sector in a 24-bay box like I have, with drives that are not exactly brand new, are not ones I'd like to bet against. Again, the risk is not zero.

Did you find the diagnostics file in the logs folder on your USB flash device?

 

Where would it be stored?  I can't seem to find it.

 

Michaels-MacBook-Pro:UNRAID $ find . -name *.zip

Michaels-MacBook-Pro:UNRAID $

 

[John_M]

From the point of view of the unRAID command line the diagnostics file will be written to the the "/boot/logs" folder. If you shut down your server and plug the flash device into a USB port of your MacBook Pro then open it in the Finder you should find it in the folder called "logs". It will be called something like "tower-diagnostics-20170116-0244.zip".

 

Regarding your hardware, you have sufficient RAM and a 64-bit processor, so no problems there.

I ran the diagnostics script and it seemed to have completed successfully.  I must have done it with the original USB stick that I have since overwritten when I restored UnRAID 5.  Because there are no files or directories on the unlicensed stick that fit what you are describing.

 

Michaels-MacBook-Pro:UNRAID $ find . -name *.zip

That is good news.

Here is how it actually works if your interested: Parity-Protected Array

Thanks.  I think it is a very simple form of a Hamming code.  This is the definitive work on those if you are interested:

Each array drive on unRAID contains a perfectly standard Linux file system and is self-contained (i.e. files are never Split across drives).  As such it can easily be read on any Linux system.  It can also be read on a Windows system using software that is capable of reading Linux file systems.

Your post lacks insight into the following points previously addressed in my post #16, above:

 

1) The files from a single share can be scattered across however many drives that are assigned to it.  Reconstructing the share in the absence of a map for which file belongs to which share, requires a file consolidation effort of some kind.  Your phrase "Easily be read" doesn't seem to reflect this effort.  Maybe the directory structure on each drive makes it easy.  I have never tried, and don't want to try.

2) You can't remove a drive with failures from a redundant array and expect to recover all the data to the last bit.  In the most common case, you need information from all the other drives, and the parity drive, to reconstruct the partly-failed drive.  Or you are into a very expensive clean room data recovery effort that can involve replacing drive electronics or read/write heads.
