'rhc tidy'没有足够磁盘空间时如何在openshift上清理磁盘空间？ [英] How to cleanup disk space on openshift when 'rhc tidy' has not enough disk space?

问题描述

 文件系统块配额限制宽限文件配额限制宽限
 / dev / mapper / EBSStore01-user_home01 
 1048572 0 1048576 6890 0 80000 
  

我发现了一个不同的stackoverflow问题可以通过'rhc app-tidy'清理磁盘空间

但是当我运行这个命令时，出现以下错误：

 警告：Gear xxx正在使用磁盘配额的100.0％
无法执行：/ var / lib / openshift / xxx / mysql的'control start'
  

当我运行以下命令时，请查看哪些文件使用的空间最大

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

我得到以下输出：

正如你所看到的git目录占用大量空间，但是当我尝试做'git gc'时，出现以下错误：

 计数对象：226，完成。 
使用多达2个线程的增量压缩。 
压缩对象：100％（192/192），完成。 
 dm-0：写入失败，达到用户块限制。 
 fatal：sha1文件'/var/lib/openshift/xxx/git/mythings.git/objects/pack/tmp_pack_ipHspL'写入错误：磁盘配额超过
错误：无法运行重新包装
  

所以现在我已经没有想法了，我可以做些什么来清理一些空间？

感谢！

解决方案

如上所述，您需要 ssh到您的盒式磁带（你会在Web控制台找到代码 - 在删除按钮旁边），然后 cd到app-root / logs ，然后运行du -sh检查当前目录的维度，在我的情况下文件 php-error.log 为 542M 。您可以使用 rm -f php-error.log安全地将其删除

My quota on openshift has exceeded:

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

I found a different stackoverflow questions that the disk space can be cleaned by 'rhc app-tidy'

But when i run this command i get the following error:

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

When i run the following command do see which files are using the most space

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

I get the following ouput:

20M git/mythings.git/objects/21
20M git/mythings.git/objects/12

As you can see the git directory takes a lot of space, but when i try to do 'git gc', i get the following error:

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

So now i am out of ideas, what can i do to cleanup some space?

Thanks!

解决方案

As mentioned above you need to ssh to your cartridge (you will find code in web console - next to delete button) and then cd to app-root/logs and then run du -sh to check the dimension of the current dir, in my case the the file php-error.log was 542M. You can safe delete it with rm -f php-error.log
