Issue
Executing /usr/share/cb/cbdiag to collect diagnostic information fails.
Symptoms
Similar errors to the below are reported in the terminal you're executing cbdiag in"
cp: cannot make directory `/tmp/cbdiag_2015-04-10_10-21-59/var/log/cb/coreservices': No space left on device
cp: cannot make directory `/tmp/cbdiag_2015-04-10_10-21-59/etc': No space left on device
cp: writing `/tmp/cbdiag_2015-04-10_10-21-59/var/log/messages-20150410.gz': No space left on device
Cause
Although the compressed cbdiag*.zip file is eventually saved/stored in your current working directory, the cbdiag uses the /tmp directory to stage individual log files before it commits the compressed .zip file to disk. If the /tmp folder is on a partition with limited space, the above "No space left on device" errors will be returned.
Solution
1. Run the following command to enumerate how much free space is available in /tmp:
2. There is a --tmpdir=dir argument built into the cbdiag script. Please run the below for usage information:
3. Specify a temprary staging directory outside of the default /tmp location. Example:
| /usr/share/cb/cbdiag --tmpdir=/more/space/here --post |
