Any messages in your logs?

How much free disk space?

Are you able to copy one file?

[b0ssman]

some more information.

which version of nas4free are you running?
what raid configuration.
what is your hardware.

[negreasrin]

now i have latest version installed ,is working and i can acces it .The error i got it on 2 versions back .
After the error i decided to upgrade and restore configuration, after upgrade ,i can access the nas but when i restore configuration with the latest working configuration i got the same error.

i have a usb as system drive and 4 x 2TB zfs
12GB ram
2.4 quad core
i got the error when i try to copy movies from download to movie folder ,about 30 GB at once

[negreasrin]

disk space was more than half free
system drive is 8gb with 2gb swap

[negreasrin]

i cant see the log when i got the error because it does not initialize the system ,the error is in the boot process.

I found this on a freebsd forum but i do not know how to do it : "

The problem was solved by specifying the vm.kmem_size_scale=1 sysctl in the /boot/loader.conf (the default is 3). Actually it needed just several MB RAM extra, about 9MB exactly, so vm.kmem_size_scale=2 should work too."

[negreasrin]

i have imported disks the zfs is restored but i do not see any data on it is like a new drive . where is the data????

[negreasrin]

about my system ,is x64

[apollo567]

Are you using the embedded version of Nas4Free ?

[negreasrin]

yes embedded.

[negreasrin]

thanks to all
i got it myself
i had installed again the latest version and forced zfs to load from console ,now all is back to normal .
i have restored an old config and just have to put things in order

thanks again

[negreasrin]

ok after a few days i got back my nas and just a day later has crashed again with same error.
the crash append again at a file transfer when i tried to backup my jails .
WHAT IS HAPPENING ?????
i did not change any settings , just the space has got about half of his size,but problems at half of size?????

[b0ssman]

What are you zfs Kerbtune settings? The new version of nas4free requires more ram. Try the settings for 8gb and see if it happens as well.

i do not use zfs kernel tune
but i will restore the nas and install the kernel tune
thanks for tip

[negreasrin]

now i have reinstalled the system and when i try to restore the zfs with zpool comands i get:
nas4free: ~ # zpool import

Are the disk all right? It would be good to se the smart status of them.

[negreasrin]

motherboard is asus p5q
the disks are ok they have been imported as zfs and status is ok

i will try to reinstall an older version and see if i can import the zpool

[Princo]

motherboard is asus p5q

That's bad.
Very bad.
According to board specifications http://www.asus.com/Motherboards/P5Q/specifications/
this is a NON-ECC motherboard.
But ECC-RAM is mandatory for ZFS.
You can read a very detailed explanation about this here: https://forums.freenas.org/index.php?th ... zfs.15449/

i will try to reinstall an older version and see if i can import the zpool

In my opinion, this wouldn't help you.
I assume your pool is damaged due to faulty RAM-Chips.
The better way is to purchase an ECC-RAM-capable System (like a HP N54L), put some extra ECC-RAM in, and restore Data from Backup.

[negreasrin]

i do not disagree but how was working about a year without problems on zfs????

and at first restore after reinstalling the system i was able to force restore the zpool ????

and now it hangs at force restore

i think maybe damaged ram could hang the process

thanks

i will read the documentation from links provided

[negreasrin]

got it working !
first clean the ram and the ram slots
second i have disconnected 1 hard drive and start my nas ,all started ok zfs report degraded
third shut down the nas and reconnect the disconnected drive
fourth started the nas ,ALL OK
after this i have installed zfskerneltune and i use 8gb settings
ALL IS OK FOR NOW

i have transferred large amount of files for testing and works ok

THANKS TO ALL FOR HELP

You can actually take backup using "Cloudbacko pro" software. I am using this osftware from long time and really satisfied using this software. It basically helps in taking backup and helps restoring too. So if you want just have a look at the software.
