Unassigned Devices Preclear - a utility to preclear disks before adding them to the array

Start by going to the cache_dirs settings and only inculding shares that need to be cached.  Normally any share on an SSD pool device doesn't need to be cached by cache_dirs.  Shares like 'isos' don't need to be cached.  Cache_dirs by default will cache everything it finds.  It can be a real memory hog.

Thank you for the replay.

 

I don't have any shares on the SSD Pool.  At least not intentionally.  And I wasn't quite sure how to do this, but I went into the settings and excluded every folder that IS NOT a normal media folder.  Hopefully this is what you were suggesting?

 

If I did do it properly, it did not fix it.  Same error on preclear attempt.

  • Not really, I assume the GUI is using some old disk info and not refreshing to get the current one, since it also happens the other way around, i.e., if you boot with a precleared disk and then format

I actually prefer the opposite.  Only include the shares you want cached.  If I remember correctly, cache_dirs will cache remote shares and that is not necessry and is wasteful of memory.

Made the changes.  Still same error.  Is it possible it's a hardware issue?  Not the drive, but the mobo or sata ports?

Maybe, but the error was a memory issue.  That's why I had you check the cache_dirs setup.  At this point I would run a memory test.

Thank you for the responses and attempts to help.  I'm switching my setup back over to an Intel board in a few days.  Seeing some other wonkiness since switching to AMD.   Will wait until I make that change and run a preclear again; see what happens.  Thanks again.

When I run the plugin from the Tools screen I get a message that says "There are no disks that can be precleared.".  But, I have a mounted disc in the unassigned Devices screen.  

When I look at the unassigned devices screen I don't see an icon for the preclear.

I've tried the plugin with the drive mounted & unmounted.  Not sure what I'm missing.

Update:  And I found my own answer.  I had to delete the partition first.

So I ran a memory test on both the old memory I was using and the new memory I just installed during the switchover (back) to an Intel setup.  All momory checked out fine; no errors.

 

But on the "new" setup, once I got everything up and running I attempted to preclear some discs.  Four discs to be exact.  They all failed and produced the same low memory error.  So I'm now using a new mobo, new processor, and new memory and am still getting the same error.  Also, during these new attempts to preclear, I stopped all dockers and VMs and shut down both services.  As you can see in the stats screenshot the system has plenty of available memory.

 

I'm at a loss.

You got it right.  So that is the problem.  It shows no space on rootfs.  I'll have to do some research and see if I can figure out why.

By the way, when I boot in safe mode I get this:

rootfs          16404780 1090788  15313992   7% /

 

And this:

rootfs on / type rootfs (rw,size=16404780k,nr_inodes=4101195,inode64)
rootfs on /mnt type rootfs (rw,size=16404780k,nr_inodes=4101195,inode64)

I was going to ask you to do that next.  That's what it should look like.  A plugin or docker is causing an issue.  Add them back one at a time until you see the issue.  Let me know what you find.

I verified it was not a docker or VM.  Same results with all dockers and VM running.  No issues. 

 

How does one go about adding plugins one at a time?

Just go to the apps and add them back.

So this is interesting.  I just booted back up under normal mode, but prior to doing so I removed .plg files from the \flash\config\plugins folder.  So no plugins are currently installed/running.  Docker is shut down and VM is shut down.  I am back to:

 

Filesystem     1K-blocks  Used Available Use% Mounted on
rootfs                 0     0         0    - /

Reboot with docker set to not start.  I suspect you have a docker container mapping issue.

Yep.  That's the condition I am currently sitting in.  Rebooted to a normal boot, but both Docker and VM services are turned off.  Plugins are all loaded and active.  Same rootfs condition.

Give me a new diagnostics in that condition.

Looking at the newest diagnistics, I have several suggestions for plugins to remove as a test:

  • Compose manager.
  • NerdTools - you may have a package being installed causing an issue.
  • Gpu stat.
  • Nvidia-driver.
  • disk location.

 

The reboot.  I don't know if any of these are causing an issue, but let's eliminate the possibility.

Dan - after rebooting the server (same old flash drive, but on a USB 2.0 port) I am not able to mount the SMB shares now.  Did you change something in the SMB setting that would prevent these from starting?

UD thinks 'SERVER-NEW' is off-line.  Turn 'NETBIOS' back on and see if UD sees the server is online.  It may be needed to recognize that server.

Yep, that fixed it.

That older server needs it enabled so UD can resolve the IP address.

 

Did the USB2.0 port change let the 'df /' work?
