I have been using a portable USB disc for storing media. After several weeks of inactivity, when I used it with git-annex again I noticed it was running very slowly. I mean, it is an USB 2.0 connection,
git-annex sync would take a few minutes, but now it takes many hours.
When adding files to it (
git-annex add), I would see the list of files passing by at the speed I would expect, but then, at the end, I would have to wait; the next day I saw the operation had completed.
git-annex status makes me wait a similar amount of time, and
git-annex sync also makes me wait, even when it has nothing to do — I saw
top reporting 100% CPU usage,
fuse were saturating the USB connection to its maximum.
File operations outside of
git-annex seem to work fine, so I can't blame the hardware or the filesystem (NTFS mounted with
