unRAID Server Release 5.0-rc5 Available

[jaybee]

This is looking good then. Is there anything outstanding now to fix that RC5 does not address? Could this become FINAL!?

[boof]

nfs + user shares.

[jaybee]

I thought NFS was fixed some people reported. What user share problem?

Please see the first post from Limetech in this thread :

 

Here's the current state of 5.0 along with what still needs to be done for "final" release.  First some known issues:

 

- NFS stale file handles when accessing user shares.  This is not fixed in -rc5, but finally I know what the problem is.  Until this is solved I recommend not using NFS to access user shares.  I'll add more info about this in a sticky...

 

and thread with further background :

[jaybee]

Oh yes. So we await the sticky with Tom's further info and findings.

Some problem cases have been fixed in RC5, but there is still a problem in other cases (I found that disabling the cache drive resolved these).

 

There is also a separate issue outstanding , which is to be fixed in the next release - to do with duplicate files occurring on user shares.

I upgraded my backup system from 5.0 Beta 10 to 5.0 RC5 and everything is working great.  Parity check speeds are exactly what they were in Beta 10.

 

The only issue I noticed is in the "upgrade notes" - They state the array should not start automatically and to verify every drives partition type; however the array did start automatically so I did not have the chance to check the partition type before starting the array.

this happens to me quite a bit not sure why ?

You need to set enable auto start to No in the disk settings.

Regarding the SAS2LP-MV8 support. I recently switched motherboards from a Supermicro X9SCL+-F to a X9SCM-F which resolved the problems with my three cards.

 

There is a new Linux driver available at ftp://ftp.supermicro.com/driver/SAS/Marvell/MV8/SAS2/Driver/Linux/4.0.0.1534/.

 

Tom: are you planning to integrate that into the next release? Is is resolving the problems you are still experiencing with those cards?

Fixed that in -rc6, thanks for pointing that out.

That issue is probably not what accounts for most "duplicates".  Usually duplicates are caused by accessing storage both via disk shares and user shares.  For example, suppose you have:

 

disk1/Movies

disk2/Movies

 

and the corresponding user share:

 

Movies

 

If you navigate to disk1/Movies and cause a file to get created there (say, .ds_store), and also navigate to disk2/Movies, and the same file name gets created, well now there's a duplicate reported when you navigate to Movies.

Very very reluctant to incorporate drivers not supplied by the linux kernel release because typically they lock us into only the set of kernels they happen to compile with.  This has been the case for example, with Realtek r8168 driver vs. kernel-supplied r8169 driver.  But pretty sure I'll be staying on 3.0.x kernel for a while, so I'll look at what those packages are...

if i say for definite my system is ONLY accessed via user shares?

 

just asking ?

[PeterB]

I would say that it's likely that you have an application accessing files on your user shares which is doing the same as on my system - creating a file, then renaming it to the same name as an existing file.

Yes that's possible.  I can probably verify if you want to send your system log that shows the 'duplicate' file names to: [email protected]

This bug is fixed in -rc6.

Thanks for the updates Tom, I'm sure you've been working hard. Take a holiday after 5.0 goes final, you've earnt it

 

Doesn't sound like it's far away now.

[pantner]

Just reporting in (i've been a bit slack, didn't upgrade to RC4 but went from RC3 to RC5) and all looks good on my end

 

loving the 5 series releases so far!

[burnaby_boy]

5.0-rc5 seems to be working fine for me, except that copying files over the network to the server seems to be somewhat slower than with rc4. With rc4 I was averaging about 30 MB/second whereas with rc5 I'm topping out at about 24 MB/second.

[optiman]

Has anyone had to replace a drive yet with version 5?  Is the process the same as before, or has it changed?

 

In short, this is what I've done in the past;

 

-run a parity check

-power down and replace drive

-power up and confirm unraid can see the new drive

-Some people run a pre-clear process, but I've never done that and don't even know how...  If we should do this step, I hope this is a button for this and no command line junk is needed.

-Rebuild the drive

-When all done, I run another parity check

-done.

 

Thanks

[Tybio]

I just replaced a 750G with a 2TB yesterday and it looks good.  Adding a new 2TB drive to the array today...looks good so far.

[optiman]

Cool, did you follow the same steps as I listed?  Did you do the pre-clear, and if yes, how?

[Tybio]

Nope, no pre-clear...yea, I know that means I'm foolish .

 

I ran those steps, but before the final parity check I also added a new 2TB drive to the array and expanded it.  That add is on-going...but I did check the replaced drive before adding the new one and the data rebuilt properly.

[JonathanM]

Nope, no pre-clear...yea, I know that means I'm foolish .

Just to emphasize the point, you are jeopardizing all the data on your server by using one untested drive. Any single drive failure requires perfect performance from every other drive in the array.
