I just got fvdw-sl installed on my 5big network 2. I have five 10tb drives in the device and I initialized each and added them to a raid5 array. The array shows up under "manage disks and volumes" but doesn't look right. Under status it says "clean completed: [0KB],, estimated time" with total size of 37244gb which looks right, but shows free space 0.00gb.

I've tried deleting the raid array but i just get an error saying "Disk not found"

Code: Select all

root@fvdwsl-base:/ # cat /etc/.setup.fs/setupjob.log
<b>Setup task destroy.sh is now running</b><br>

After rebooting and checking dmesg I see this line...

[   46.962647] EXT4-fs (md0): filesystem too large to mount safely on this system


Hmm what is causing that? Am I doing something wrong?

Hi norax

The first thing would have to do was to install the patch available here: https://plugout.net/viewtopic.php?f=7&t=2695Indeed on very large fs, you have some memory allocation errors with e2fs tools

But if I understand rightly the current state of your nas, you can no longer install this patch.
To check it please to post the output of

Code: Select all

mount

:disapprove
Anyhow your nas can not handle a fs size bigger than 16TB (cpu 32bits)

Thanks thats kind of what I figured. I opted to make two RAID1 arrays out of my five 10tb drives. Thats probably the best i can hope for. Thats better than the original firmware allows.
