Support for PLX-NAS7820 Systems?

[jedie2]

Will be PLX-NAS7820 based system supported in the future?

Similar boxes are:
MEDION LIFE P89626 NAS -> http://www.mikrocontroller.net/articles/P89626 (de)
Pogoplug Pro/Video/v3 -> http://archlinuxarm.org/platforms/armv6 ... provideov3
Iomega Home Media Network Hard Drive, Cloud Edition -> http://iomega.nas-central.org/wiki/Cate ... e_Media_CE

I have the MEDION LIFE P89626 NAS and tried http://archlinuxarm.org/os/ArchLinuxARM ... est.tar.gz

It worked via chroot, see: http://www.mikrocontroller.net/articles ... chLinuxARM (de), but starting the kernel doesn't work:

After the last line, the box hangs and I get some beeps...

[WarheadsSE]

Did the Medion have the PCIe bus logic on the board? That might be the problem, as that is very similar to what happens on the Pogoplug P21/B0X

[WarheadsSE]

Oh, and you might want to point it at a rootfs.

[WarheadsSE]

You'd need to append/prepend that to the bootargs line. I would also attempt to boot the uImage.nopci as well.

I think it's telling you
$this->bbcode_second_pass_code('', '[ 2.430000] VFS: Cannot open root device "sdb1" or unknown-block(0,0)
[ 2.440000] Please append a correct "root=" boot option; here are the available partitions:

[ 2.460000] 0802 1464621952 sda2
')
Tried sda1 or 2? I don't know if ext4 works

[jedie2]

sda ist the HDD. At this used XFS with RAID.

We disscuss to resize the XFS Partitions and append a ext2/3 for the rootfs.

[xenoxaos]

The kernel for the 7820 does not support xfs worth a damn. PLX/Cloud Engines really did a hack job on the kernel to get the oxnas chip to work and properly messed up xfs support. The oxnas lines that we support are currently set up to boot from the first partition, sda1, that is formatted as ext3.

[jedie2]

I would like to know why RAID and XFS are used?
RAID made no sense IMHO, because my box has only one HDD...

Some say XFS is faster. Others say ext4 is faster. IMHO the performance difference vary more than that you could make a clear decision, isn't it? ext4 is more common and therefore to be preferred.
