Hi,
I am archiving some old disks and while trying to umount [-f] them I am
getting errors and I basically cannot get rid of the mount anymore
without rebooting. This is on a HEAD from mid-end-August (around
r351518M).
Given there is a lot of work going on at the moment to deal with
“disks dropping out by error” and not to panic I was just wondering
if this is something to address as well? Somehow umount -f should be
able to succeed (in the future)?
fsync: giving up on dirty (error = 5)
