由于某些愚蠢的原因,Ubuntu 14.10 现在堆满了/tmp
文件。有数百万个。
dmesg
向我展示了数千行这样的代码,
[15686.146977] ecryptfs_create: Failed to create file inlower filesystem
[15686.376336] ecryptfs_do_create: Failure to create dentry in lower fs; rc =
最后,我不得不从记忆棒启动并自行运行rm -rf /tmp
和重新创建。这个问题的原因是什么?我升级了系统,它工作了一段时间。然后它给我带来了问题,当我重新启动时,我得到了大量错误。我花了一段时间才找到它,但这似乎不是一次性事件。现在我的磁盘已满,由于所有这些临时文件,我无法执行任何写入磁盘的操作。
更新
有趣的是,其中的所有文件/tmp
都包含 cups ppd 文件的内容……

(此处文件被截断)。
进一步来说/var/log/cups/error_log
,我有很多这样的条目......
E [timestamp] Unable to create "/var/cache/cups/job.cache.N": No space left on device
E [timestamp[ Unable to create "/var/spool/cups/c00196.N": No space left on device
E [timestamp] Unable to create "/etc/cups/subscriptions.conf.N": No space left on device
E [timestamp] Unable to create "/var/cache/cups/job.cache.N": No space left on device
E [timestamp] Unable to create "/var/spool/cups/c00196.N": No space left on device
经过进一步检查,我发现这些都是指向同一个 ppd 文件的符号链接。
find . -not -type d -exec ls -al {} \;

看来这是一个已报告的错误。尽管极难发现。
此错误已在 system-config-printer - 1.5.3+20141027-0ubuntu1 软件包中修复
并且,在更新日志中,
