Re: BTRFS Raid5 error during Scrub.

[Robert Krig <robert.krig@render-wahnsinn.de>]

By the way, how serious is the error I've encountered?
I've run a second scrub in the meantime, it aborted when it came close
to the end, just like the first time. 
If the files that are corrupt have been deleted is this error going to
go away?
