RN104 GUI slow or not loading

There is no backup.  How do I check to see if the USB is mounted? 

I want to use the cp command to copy the whole /data folder to the backtop usb.  What is the command?

cp /data /backtopusb/

lsblk should show you.  Normally the internal disks would be sda, sdb, sdc, and sdd.  The mount point would be the last entry on the line.

If the USB device is mounted as /usbdrive then you'd want

cp -R /data/* /usbdrive/data

Guessing this is the issue:

root@NAS:/dev# lsblk

sde 8:64 0 4.6T 0 disk
├─sde1 8:65 0 200M 0 part
└─sde2 8:66 0 4.6T 0 part

root@NAS:/# mount /dev/sde2 /mnt
mount: unknown filesystem type 'exfat'

Wow I learned a little linux today.  RN104 didn't support exfat (to which my question about partitions earlier should have resolved this)

So I did the following:

"sudo apt install exfat-fuse exfat-utils" then

" mount /dev/sde2 /mnt" then

"cp -R /data/* /mnt/NAS/"

and done!  of of course umount when done :)

Great!  I'm glad you got the volume backed up.

How is it that the GUI is so slow and barely functions but the console works fine?  I figured this was a disk issue but it feels like a control or mgmt plane issue.  Is there anything I can try before factory resetting?

I also downgraded 6.10.5 to 6.10.4 and no change.

The GUI runs at a fairly low priority, so if something is consuming the system resources it will be starved before other functions. 

You can try running top, and see if something is taking a lot of CPU time.

Okay I found the solution to my issue, so let me recap for others. 

Plex was slugglish or quit working which is what alerted me to any issue.  SMB shares were available for a few days but ended up failing as well.  GUI was very slow and web pages took minutes to hours to load, sometimes not at all.  Was barely able to upload the previous firmware but that didn't fix the issue.  From a previous post you can see I was able to mount an external and backup everything via SSH.  From there I factory reset the box and that still didn't fix the issue but did point me in the right direction.  After the reset, the drives kept trying to sync for hours even though there was only 12MB of data.  Once I deleted the partition everything came back to life.

Not sure what you mean.  Are you saying you deleted the data volume?

Yes the volume.  Do you think the X-Raid is better than Raid-5?

For most users, yes.  If your disks are equal size, then it is RAID-5.  If they are of unequal size, XRAID will give you the more capacity.

FWIW, the GUI performance will be slow when the volume is resyncing (and that is required in both RAID-5 and XRAID).  Since resync takes place at the block level, the resync time is the same whether the volume is empty or full.
