importing ZFS Raid-z causes kernel panic

[potato]

hello
I just did a fresh install on a USB of the latest release
everything was working fine before this

I can auto-import everything except the raid drives
the drive shows up fine in both the auto-import and the shell zpool import

however, as soon as I try to import, the computer immediately goes crazy for 10 seconds and reboots
I am going to assume this is a kernel panic?

I have tested the computer memory, it is fine
I am not familiar with the 9 version of freenas very much
I heard the memory size can be adjusted in tunables? and if it is too low it can cause a panic?

any advice is appreciated

How much memory do you have? FreeNAS 9.x requires 8 GB minimum and this sounds like you are short on memory.

hi
wow that's alot of memory,
I am only using 4GB but I downgraded to the 32bit version for the 9version

The 32 bit version and UFS are both deprecated for the upcoming 9.3. You will need a hardware upgrade if you want to continue using FreeNAS.

hi
thanx for the replies
wow, that's crazy, I was recommended freenas and recommend it to others as a way to reuse old hardware
but I guess if they can be a serious professional alternative to commercial competitors, then that's great too

Ok, I will install on an AMD FX workstation with 8GB and see if that solves this and try to recover the data
I'll post back tomorrow, thanx

FreeNAS is a NAS platform with relatively heavy requirements compared to many others, largely because it was designed for ZFS and because it was designed for large deployments. If you want a NAS that's designed for old hardware with limited resources, there are better choices out there.

I will note that I have seen problems importing a pool created on FreeNAS 8 with FreeNAS 9, a problem that shouldn't occur.

hi thanx for the reply
Ok, this is absolutely not a problem with the memory
I just used 8GB of relatively new DDR3 on a brand new freenas install
this seems to be a software bug issue or corruption from upgrading/re-installing

I also am confident it is not the memory, as I said before, it happens immediately on pressing enter and I consistently recreate the kernel crash everytime
I also found out freenas won't install to a USB3.0 port

you know, alot of people say ZFS is safer, better. etc.
but none of that even matters if you can't access the folder
I have read people losing all the information on their NAS just from a simple power failure
before i re-installed i did reset back to factory settings, maybe I did not dismount the disc properly, idk

anyway, I am out of ideas
thanx for the help though

You could see if it seems similar to https://bugs.freenas.org/issues/4721 and if not post a bug report.
