当'rhc tidy‘没有足够的磁盘空间时，如何清理openshift上的磁盘空间？

Question

我在openshift上的配额已超过：

 Filesystem  blocks   quota   limit   grace   files   quota   limit   grace
 /dev/mapper/EBSStore01-user_home01
            1048572       0 1048576            6890       0   80000        

我发现了一个不同的堆栈溢出问题，磁盘空间可以通过'rhc app-tidy‘来清理。

但是当我运行这个命令时，我得到了以下错误：

Warning: Gear xxx is using 100.0% of disk quota
Failed to execute: 'control start' for /var/lib/openshift/xxx/mysql

当我运行以下命令时，请查看哪些文件占用的空间最多

du -h * | sort -rh | head -50

我得到以下输出：

605M    wildfly

320M    git/mythings.git

正如你所看到的，git目录占用了很多空间，但当我尝试执行'git gc‘时，我得到了以下错误：

Counting objects: 226, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (192/192), done.
dm-0: write failed, user block limit reached.
fatal: sha1 file '/var/lib/openshift/xxx/git/mythings.git/objects/pack/tmp_pack_ipHspL' write error: Disk quota exceeded
error: failed to run repack

所以现在我没有想法了，我能做些什么来清理一些空间呢？

谢谢!

Answer 1

删除您可以轻松地从备份或包中恢复的任何内容，例如JDK。这应该会给你足够的空间来做清理。然后恢复您删除的所有内容。

或者支付更多的存储空间。:-)

Answer 2

如上所述，您需要将ssh到您的cartridge (您可以在web控制台中找到代码-删除按钮旁边)，然后将cd到-/logs，然后运行du -sh来检查当前目录的大小，在我的例子中，文件php-error.log是542M。您可以使用rm -f php-error.log安全地删除它

Answer 3

使用ssh clients (i use putty)或command prompt ssh到应用程序目录，然后尝试找出不必要的文件并将其删除。

在我的例子中，删除app-log文件夹的内容就像是在施展魅力。

注意临时文件夹和日志文件夹
