I'm seeing huge latency sometimes when unmounting ext4 partitions. Steps that triggered this most recently:
sudo -s
cd /tmp
dd if=/dev/zero of=test.ext4 bs=1 count=1 seek=1G
mkfs.ext4 test.ext4
mkdir /mnt/test
mount -o loop text.ext4 /mnt/test
echo $(seq 65536) | (cd /mnt/test; xargs touch)
time umount /mnt/test
I'm seeing upwards of 5 minutes for the umount to finish. |
