Hi guys

 

First time I need some help with unRAID, so I hope I included everything needed.

 

My story goes like this:

 

My wife started complaining about the noise from my server. So I thought I would make it sleep when not using it. Therefore I installed a plugin called "Dynamix S3 Sleep". That works fine, and my server goes to sleep after being inactive. However, once when I started it again one of the disks in my array said it needed to be formatted. I thought, that is weird, but OK and hit the format button. Once it was formatted I stopped the array and took the newly formatted disk out of the array, then I started the array again. After that I stopped the array again and put the disk back into the same spot, and let the array rebuild. 

 

After the array was rebuild I noticed that all of my Dockers and my VM was missing (I had not paid attention to that while messing with the array, so I am not sure at what point they disappeared). I could fairly easily get my Dockers back up and running by using the user templates it had saved previously. However, I don't know how to get my Windows 10 VM up and running again.

 

I have attached the diagnostics from my server, so maybe someone can figure out what happened?

 

Thanks a lot in advance!

Best regards

Kinda mistake #2, but a pointless step.

 

Net result is that you formatted a drive with all of your information on it.  You could rebuild 100 times, and the parity process will still rebuild what is effectively an empty drive.

 

Based upon your disk usage, you formatted and lost everything that was on disk #1.  unRaid is no different than any other OS.  Formating erases the disk.

 

As far as I can tell, your docker applications should be running.  binhex deluge, plex, sonarr all say they started up, but for some reason the docker log is empty.  (same with the libvirt log)

 

 

Thanks a lot for your reply Squid.

 

I can confirm that I lost data, unfortunately. Hopefully my cloud backup can rescue me now. 

 

I would like to know how I should have proceeded instead of formatting the disk. Maybe I should have stopped they array and removed the disk from the array, and then formatted the disk?

 

I assumed that formatting the disk and then re-adding it to the array, would allow me to rebuild the array without data loss. Like it should allow when a disk fails.

 

Thanks in advance!

Formatting a drive in unRaid is the same as in every other OS.  You wipe the contents.  Parity information is always real-time, so if you then rebuild, all you're doing is rebuilding an empty drive.

If you ever see an unmountable drive, then basically you need to Check Disk Filesystem on it.  (And post here for the expert advice)

As above, nope.  Parity information is only ever used to recover failed drives.  A drive that is unmountable isn't failed, but rather corrupted, and any write operation to the drive (ie: format) will update parity to reflect the fact that you now have an empty formatted drive.

OK - nice to know!

 

Thanks a lot for your help Squid
