Kmem_malloc freeze me.

[BenGonGon]

Hello,
I have a problem.
Freenas freeze and give few line before :

panic Kmem_malloc (131072) . Kmem_map too small 334520320 allocated.
CPUID = 0
Uptime 13h8m36s
Cannot dump. Device not defined or unavailable.
Automatic reboot in 15 seconds - press a key on the console to abort.

I was previously understanding in reading forum, it is a ram problem.
I have put 8Gb ram and I have always the problem.
Please, who can help?

Can you tell me where I can have this information, please?

You are using the 32bit version so upgrading to 8GB has no effect, on a 32bit system (independent from the OS) you will get only 3.xx GB RAM max.
The Pentium 4 D (socket 775) is able to run a 64bit OS (recommended for FN8), maybe that will solve your problem.

 

[BenGonGon]

I use : FreeNAS-8.0-RELEASE-i386.iso from http://sourceforge.net/projects/freenas/files/FreeNAS-8/ .
You tell I do use FreeNAS-8.0-RELEASE-amd64.iso from http://sourceforge.net/projects/freenas/files/FreeNAS-8/ ?
It is an Intel processor not an AMD.
Where do i download the right version?

 

[ohnename]

They should change the name, you are not the first one who was thinking AMD64 is AMD only :)
AMD64 means 64bit, this include Intel CPUs with EMT64.
If your CPU is really this one:

Platform: Intel(R) Pentium(R) D CPU 3.00GHz

A Pentium 4 dualcore Socket 775 then you can use the 64bit version

 

[BenGonGon]

I understand better now, thank you.
I install the FreeNAS-8.0-RELEASE-amd64.iso from http://sourceforge.net/projects/free...les/FreeNAS-8/ ?

I backup freenas in

System
Settings
Config
Save Config

Install the FreeNAS-8.0-RELEASE-amd64.iso

I restore freenas in

System
Settings
Config
Upload Config

And it is safe for all recorded data?

 

[ohnename]

I´ve never done a 32bit -> 64bit upgrade but it seems that you can update using the GUI:

[Tekkie]

If you don't know that AMD64 means x86-64bit then you probably should not be toying around and building your own NAS, go and buy a COTS NAS device as you will safe yourself a lot of headache. ;)

 

[BenGonGon]

thanks for your comment Tekkie but it is not useful here.

OhneName, I have follow your link and I have see variables to modify.

vm.kmem_size="512M"
vm.kmem_size_max="512M"
vfs.zfs.prefetch_disable="0"

Who can explain me the utility of this variable?

 

[ohnename]

You have to change the vm.kmem_size in loader.conf file only for a 32bit system not for a 64bit system

 

[Tekkie]

thanks for your comment Tekkie but it is not useful here.

Its actually very useful, building a system like a NAS that uses FreeBSD which is an OS more exotic than Linux requires experience, your comment about AMD64 let me to believe that you are not somebody who 'plays' around with hardware/OS on a regular basis, if that assumption was wrong then please disregard my posting and the rest of this posting and I apologies.

But if my assumption is right then please be careful especially when you start tinkering with kernel parameters because you can loose your music, movies, pictures etc. when things go bad.

Seriously? It fricken says AMD. I have been coding, network engineering, and building computers since before IBM PC's came out and I downloaded the i386 first. If it is a 64bit release it should say 64bit without the AMD. The entire point of FreeNAS is to give folks an EASY way to build a NAS. That was kind of a d-bag comment.

 

[BenGonGon]

Tekkie, I hope I have not hurt you. If yes, I apologise me.

Torrin, thank you, I feel me less alone and ashamed.

I have not habit of linux but I am system administrator of ~50 workstation, 6 blades, 1 cluster and ~10 server in virtual machine. before that, I was in freelance in compter services.

I have choice freenas system for make me a monstruous private storage.
I wish centralise all my data at home.

8GB Ram and 5 x 3 TB HDD in Raidz1

Now we can return in principal subject.

I download and install the 64 bits version, now.
I give you feedback as soon as possible.

Good luck. I am running 8GB + 6x1.5TB RaidZ2 here, and with R8.01Beta2, my system is humming along well.
