如果大家 FreeBSD 是在 VM 裡.或者實體擴充比較麻煩. 可以試著以下方式. 透過 dh -h 檢查空間使用(其實實際有100G) Filesystem Size Used Avail Capacity Mounted on zroot/ROOT/default 18G 18G 74M 100% / devfs 1.0K 0B 1.0K 0% /dev zroot/var/mail 1.7G 1.6G 74M 96% /var/mail zroot 74M 88K 74M 0% /zroot zroot/usr/home 824M 750M 74M 91% /usr/home zroot/var/log 188M 114M 74M 61% /var/log zroot/var/crash 74M 88K 74M 0% /var/crash zroot/usr/src 949M 875M 74M 92% /usr/src zroot/var/audit 74M 88K 74M 0% /var/audit zroot/var/tmp 74M 92K 74M 0% /var/tmp zroot/usr/ports 6.1G 6.0G 74M 99% /usr/ports zroot/tmp 75M 668K 74M 1% /tmp 透過 bectl list 列出 Active 狀態 - 是沒在用 , NR 是現在的.

在 freebsd-update install 時會做下面的事 (update) Creating snapshot of existing boot environment... done. patch 或者跨版都會.UFS 沒有看到.. UFS 的只有 /boot/kernel.old ※ 編輯: asdfghjklasd (140.238.52.217 日本), 10/12/2025 18:31:19
