2 Computers try to write

[Snuups]

Hi Folks. I narrowed my problem down a bit. As soon as 2 writes occurs the unRAID kills the Shares/Mount on the computer who started writing second. First computer will be halted or is slow, like 2 MB/s. Is there a way to enhance speed for multiple users?

 

Maybe my explanation ist not accurate. I an no native english speaker. I will answer any question as good I can.

 

There is another issue. When I copy files to unRAID I have to overwrite some. Every time. Even copying into an empty folder.

 

Any ideas?

Noone has an idea what my problem is? unRAID is pretty much unusable this way. Please I am desperate. I hope I have not wasted my bucks into a toy.

RAID controllers are not recommended.

[Snuups]

It's configured as JBOD. I read that is the way to do.

 

What can I do? I need the unRAID to run.

I tried a 9305-24i Controller but it's not detecting any HDs. I slowly get the impression that unRAID was a huge waste of money. some bucks for the software and plenty for probably useless hardware I have no further use. And of cause probably loss of data. WE'll see about that.

This should be plug'n play, please post diags with the LSI.

[Snuups]

I'll try this. 😞 Such a pain.

 

Evenrytime iI write on unRAID it started asking if I want to overwrite something, even in an empty folder.

The symptoms you are describing are not typical.  There has to be something going on at your end that is causing them.

What exactly is the "it" in this statement?

[Snuups]

German: Wenn ich Dateien kopiere startet er mit ca. 100 MB/s. Das bricht nach 30 Sekunden aud 30 - 50 MB/s ein. Nahc einer Weite fargt windows ob ich Datenen überschreiben möchte die im Ziel bereits vorhanden sind. Das tu er auch, wenn ich in ein leeres Verzeichnis kopiere.

 

English: When I copy files it starts with about 100 MB / s. This drops to 30-50 MB / s after 30 seconds. After a while, windows asks whether I want to overwrite data that already exists in the target. It does the same when I copy files into an empty directory. I usually copy 500 GB ore more et the time. Copy like 4 or more TB fail at some point.

2 steps forward. 3 staps back.

 

I tried a LSI SAS9305-24i controller. This one recognizes no HDs at all. What am I doing wrong? I just don't get it.

Are you sure you have got the right cables for connecting the disks?    They come in ‘forward’ and ‘reverse’ variants that look identical but are wired differently.

[Snuups]

Yes, absolutely. It worked already on another backplane.

Controller is failing to initialize:

Make sure it's using the latest firmware, you can also try the latest Unraid beta, there might be some driver difference.

[Snuups]

I still have not figured out how to upgrade to a Beta OS. Still reading stuff here.

Though doubt it will help, still won't hurt to try, and if it's still the same it's likely a HBA problem.

[Snuups]

If you are running a 6.4 stable release or newer, go to the Tools/UpdateOS page and select the Next branch.

 

I tried that many times, it jumps always back to stable. I thought I have to look somewhere else.

 

I try the Card in a Pc now. Maybe ich can find something.

[Snuups]

So far the Controller has newest BIOS Firmware or whatever. I think this thing does not work with the SuperMicro backplane. It don't display any HDs.

[JorgeB]

It should work correctly with any Supermicro backplane, what model backplane do you have?

[Snuups]

AFAIK BPN-SAS2-846EL1 SAS Expander Backplane

[JorgeB]

Should work fine, but note that you can only connect one or two minSAS cables, since it's an expander backplane.

[Snuups]

I have only connected 1 cable.
