I haven't had a chance to take a closer look at this problem until now. (In reply to Loris Luise from comment #8) > Hello, > > what can I do on my side? I am not sure whether you use 'delalloc' on your system. I don't see these details from the log that you pasted. So now only I could suggest is that you can try to turn off the delalloc. The step is as below: % sudo mount -t ext4 -o remount,nodelalloc ${DEV} ${MNT} After this, it won't track the delayed entry on extent status tree. So it will avoid es shrinker to take too much time to scan delayed entries that couldn't be reclaimed. Then I will try to reproduce this problem on my sand box and think about how to improve es shrinker.
