Hi Hive Mind,
Does anyone have any thoughts on removing the sticky bit on the
/var/tmp directory and setting it to 777?
Something about it doesn't sit quite right with me but I can't so far
find any negative impact of doing so.
The reason for this is that we have a large amount of data moving
through that folder, in the order of more than 100GB. We have cleanup
scripts which need to be able to remove files and folders to reclaim
space every time a job finishes but the files are created by the user
who launched the job, and the control process, and hence the cleanup,
runs as a different user. And there we have a problem as the sticky
bit prevents the cleanup from running and we have boxes falling over
because their disks fill up.
I'm fairly sure the first response to this will be "Use sudo", as that
was our first response too, or "store the data somewhere else". Both
of these are possible but difficult, the latter exceedingly so. We've
tried to think of every sensible alternative but the simplest fix
would be to just change the permissions and hope there isn't something
which is going to bite us as a result.
Any cautionary tales gratefully received.
Cheers,
Craig
