Balance terminating

Balance terminating

[Swasher]

Hello, i'm started balancing on my raid0:

$ btrfs fi show
Label: none  uuid: efdcd026-f5f0-49e7-a173-8eb777018119
        Total devices 3 FS bytes used 4.57TB
        devid    3 size 1.82TB used 1.82TB path /dev/sdd
        devid    1 size 1.82TB used 1.82TB path /dev/sdc
        devid    2 size 1.82TB used 1.82TB path /dev/sdb

Btrfs Btrfs v0.19

After it, I'm start watch for progress via 'balance status', and I can see how 
progress run. But only for 83% left. 

I'm wait few hours and try cancel it with 'balance cancel'.
More than 12 hours had passed, but balance stalled in this state:

$ btrfs fi balance status /mnt/raid/  
Balance on '/mnt/raid/' is running, cancel requested
386 out of about 2231 chunks balanced (387 considered),  83% left

Question: Can I'm safetly reboot server? Or should I do something else?

What's the kernel version?

Yes it's safe. Please note that an interrupted balance will continue on
next mount unless 'skip_balance' is specified (and then balance cancel
will clear the state from the fs).
