请帮助我,当我尝试增加 LVM 中的分区大小,但当我尝试它不起作用时,我执行以下操作:
df -h
Filesystem Size Used Avail Use% Mounted on
udev 3.9G 0 3.9G 0% /dev
tmpfs 795M 1.3M 794M 1% /run
/dev/mapper/ubuntu--vg-ubuntu--lv 244G 113G 121G 49% /
sudo lvextend --resizefs -l +100%FREE ubuntu-vg/ubuntu-lv
Size of logical volume ubuntu-vg/ubuntu-lv unchanged from <248.00 GiB (63487 extents).
Logical volume ubuntu-vg/ubuntu-lv successfully resized.
resize2fs 1.45.5 (07-Jan-2020)
The filesystem is already 65010688 (4k) blocks long. Nothing to do!

之后一切都保持不变。我不明白我做错了什么。更准确地说,我还没有完全了解。
答案1
LV 已达到约 247 GiB 的最大大小,并且没有更多可用区可供分配:
vgdisplay --- Volume group --- VG Name ubuntu-vg ... VG Size <248.00 GiB PE Size 4.00 MiB Total PE 63487 Alloc PE / Size 63487 / <248.00 GiB Free PE / Size 0 / 0
它包含的文件系统有一半多一点仍未使用:
df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu--vg-ubuntu--lv 244G 113G 121G 49% /
答案2
我真是个傻瓜啊。出于某种原因,我认为这一切都可用,而不是还剩下多少。出现这种想法是由于磁盘空间不足的错误。但实际上一切都很好。抱歉胡言乱语(
