Synology NAS /tmp の空き容量
次の様に /tmp 以下に zip を作成していたら，エラー（No space left on device）に．

空き容量を表示する df コマンドで確認すると，
Iwao@DS116:/tmp/Iwao/i_Tools.tmp/20190121/tst$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 2.3G 920M 1.3G 42% / none 502M 0 502M 0% /dev /tmp 504M 501M 2.7M 100% /tmp /run 504M 4.9M 499M 1% /run /dev/shm 504M 4.0K 504M 1% /dev/shm none 4.0K 0 4.0K 0% /sys/fs/cgroup /dev/sda3 2.7T 495G 2.2T 19% /volume1 Iwao@DS116:/tmp/Iwao/i_Tools.tmp/20190121/tst$
確かに空いていない．
NAS を再起動して対応．
