Title:
ntfs copy kills ubuntu
Status in linux package in Ubuntu:
Confirmed
Bug description:
This is trivial to reproduce - just plug any external drive with ntfs
and copy smth substantial to local ntfs partition. The result - mouse
doesn't even move most of the time, the system is useless and
unresponsive until copying is finished.
Yes, ntfs is not native on GNU/Linux but nevertheless - this is very
common task on loads of dual boot installations. And under no
circumstances it should make ubuntu useless as it does now. I don't
care much if copying big files to/from ntfs takes 5 or 10 minutes as
long as I can actually keep using ubuntu in a meantime.
Note the same effect can be observer while copying between ntfs and
ext4 or btrfs - only in this case you can sometimes move mouse pointer
a bit.
I hope that using BFQ
http://algo.ing.unimo.it/people/paolo/disk_sched/ and some of systemd
magic might help in this case.
