Mac OS X 10.13 Slow, acting weird, Disk Utility Errors, Finder Hangs, Can't Open Finder Windows: Drobo!

Update: Seems to be working now but I didn't do anything super technical. I still don't know what the issue is. I think maybe some sort of tiny disk error or issue that the Drobo or Disk Utility corrected...but nothing I could see. If I could only see those secret Drobo logs. But I might panic if I saw the sausage being made.

Update 2: I replaced the USB 3 card and cable because it seemed like that was a factor. The mouse and keyboard would stop working during these system hangs. It has greatly improved my Drobo 3 read/write times...so read the next post up about that swap. I benched it just now at around 100MB/sec which ain't shabby. 

One note is if your Drobo series 3 falls below 15% free space, performance SUCKS. I'm at 12% free and it still sucks.

I'm playing with Unraid, and will be selling my Series 2 Drobo at least. 

Working on this issue as I write and here's what I think solved issues for me:

Drobo 3 wasn't mounting the Time Machine or regular volume (it would only mount one) on the desktop as it should. Right now I'm running Disk Utility First Aid on it. I also have Drive Genius and I may pull the drives to check their SMART status and sector scan them in a sled on my desktop Mac Pro. This shouldn't do anything to the disk as it won't understand the file system to potentially write to anyway, I believe.

(Someone comment if I'm wrong.)

I'm also going to finally, two years after release, upgrade to 10.14 Mojave.

The finder preferences were perhaps corrupt. I deleted them using the terminal as I could not even open finder windows to do it with the GUI.

I'm on OS X 10.13.6...and thank God I have a budget gaming laptop running Windows 10 to type this on.

Also:

I had what looked like an aborted Time Machine backup hanging around and it throws TONS of errors in Disk Utility when you run First Aid.

Here's how to delete them:

And here's how to turn off mobile backups if you have a desktop or just want to save space. 

MacWorld Article 2

I don't know the purpose of a Mobile Backup for me, personally, as I'm always connected (nearly 100% of the time) to my Drobo 3 anyway.

After deleting the bad snapshots using the instructions in article 1, my boot drive went through First Aid no problem.

Personal Note: my company is entirely gone in about two weeks due to Covid19. Please give me a Subscribe on my YouTube channel so I can monetize it. 

Honestly, there's some good tech and money videos on there. Thanks for helping me out.



Unraid 6 and Time Machine: Can't Mount Share in Time Machine Preferences

 From the Unraid wiki: (https://wiki.unraid.net/UnRAID_6/Configuring_Apple_Time_Machine)

"From here, there are just a few more steps:

  • Connect to your Time Machine share by connecting to it through the Finder.
  1. Next: go to Time Machine Preferences on your Mac and “Select Disk”.
  2. Your newly mounted Time Machine share should show up. Select this share, enable encryption if desired and click “Use Disk”.
  3. Now, Time Machine will say it’s trying to connect to your share. Before clicking connect, it’s recommended to eject your mounted share from your desktop and then connect.
  4. Time Machine immediately begins making periodic backups—automatically and without further action by you."


Simple fix: in my case, under OS X 10.13.6 High Sierra, I HAD to eject the mounted share. So it's really more like a requirement.

The gist of it is: Mount your share so the Time Machine Preference Pane can 'see' it, and then when the window asking for your password and user to connect is open, switch back to the Finder and eject the share THEN hit connect.

I'm out of work. No job. :) Buy me a cup of coffee or what you'd give any other IT savvy panhandler here: 


Will solve OSX/Unraid/SMB issues for food.
