Have issues with 100% diskspace in your Linux dedicated server. An easy and quick way is to clear the log files<\/a> and thereby you can acquire quite a large amount of usable diskspace.
\nCheck the following:
\n1. Check the total disk usage:
\n[root@testserver \/]# df -h
\n2. Check the size of a each folder:
\n[root@testserver \/]# du -sch * or du -sch \/foldername command<\/p>\n

<\/p>\n

3. Suppose if error logs is taking a lot of space, you can always try to clear it. You can keep x number of latest entries for your reference and can null the old entries.
\nTo achieve this, perform the following:
\n[root@testserver \/]#\u00a0 vi error_log_new \/\/ create a new file to save the latest entries
\n[root@testserver \/]#\u00a0 tail -1000 error_log >\u00a0 error_log_new \/\/ this copies latest 1000 entries from error_log to error_log_new
\n[root@testserver \/]#\u00a0 > error_log \/\/ clear the contents
\n[root@testserver \/]#\u00a0 mv error_log_new\u00a0 error_log \/\/ move the contents of the latest error_log to the cleared file
\noverwrite?: yes<\/p>\n
