Hi,

 

I use a usb drive to backup my share once a week.  Its a usb i use for other machines to take backups.  The usb drive has been fine up to now and still works in the other machines but in the last few days it wont mount on unraid saying in the log its already mounted. I think i must have disconnected it previously without a clean unmount.  Is there a way of fixing this without rebooting the server?  Ive tested my other usb drive which is the same usb model and that one mounts fine on unraid.

 

Im still on 6.8.3 at the moment on my HPZ620.  Diags attached.

Unlikely.

What is the safest way to reboot?  Manually stop Vms and dockers first or just use the reboot option in the gui without manually stopping anything?

 

I dont reboot very often unless i have to.

GUI reboot might work but depends on how your VMs are configured and the set timeout, if possible always best to stop them first, dockers should not be a problem.

Stopped the VM and rebooted and all seems ok now.  I have the unraid upgrade to do next. 6.8.3 to 6.9.1.

 

Is there anything i need to be aware of before doing the upgrade? I have a backup of the usb.

 

Is it quick and simple like the plugin upgrades just with a reboot?  Then if there is an issue, is the rollback just copy the backup usb files over the top of the new and reboot again?

Always good to read the release notes.

Usually yes.
