sudo freshclam 失败--权限问题？

freshclam尝试以超级用户身份在 Ubuntu 18.04 上手动运行时出现以下错误（我已经按照其他问题所述停止了守护进程）。

# sudo freshclam

但是手动创建文件是可行的，所以我不确定这是否是权限问题。

# mkdir /var/lib/clamav/clamav-63297260eb8cf259cb59552e4bddc3b3.tmp/
# dd if=/dev/urandom of=/var/lib/clamav/clamav-63297260eb8cf259cb59552e4bddc3b3.tmp/clamav-7802c73731c6f7f34959ac4d37b24f6e.tmp count=5840

我找到了以下两个来源：

https://forums.cpanel.net/threads/getfile-cant-write-1448-bytes-to-usr-share-clamav-clamav-917a563483a6171fe02eac005.125857/

https://www.linuxquestions.org/questions/debian-26/warning-can%27t-download-main-cvd-from-db-local-clamav-net-786955/

但是他们的建议也无济于事（我没有配额，并且我尝试停止 AppArmor，但问题仍然存在。）

还有其他想法吗？我应该检查什么？

好的，我找到原因了：磁盘已满。

为了使答案完整，我在这里留下我的解决方案，如何使用卷扩展磁盘大小：

# df -h /
Filesystem                         Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-ubuntu--lv  3.9G  3.7G     0 100% /

我们需要/dev/mapper/ubuntu--vg-ubuntu--lv

# lvresize -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv
  Size of logical volume ubuntu-vg/ubuntu-lv changed from 4.00 GiB (1024 extents) to <14.00 GiB (3583 extents).
  Logical volume ubuntu-vg/ubuntu-lv successfully resized.


# resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
resize2fs 1.44.1 (24-Mar-2018)
Filesystem at /dev/mapper/ubuntu--vg-ubuntu--lv is mounted on /; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 2
The filesystem on /dev/mapper/ubuntu--vg-ubuntu--lv is now 3668992 (4k) blocks long.


# df -h /
Filesystem                         Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-ubuntu--lv   14G  3.7G  9.5G  28% /
