I am running smrtanalysis software which is very demanding in terms of cpu, RAM and storage. After running for couple of hours, I got following error message:
IOError: [Errno 13] Permission denied: '/afs/bx.psu.edu/user/s/szr/smrtanalysis/tmpdir/tmpqNMh9s'
However, when I check the files, it seems that permissions are set OK (I am starting program as biomonika):
[biomonika@brubeck tmpdir]$ ls -l tmpqNMh9s -rw------- 1 biomonika biomonika 639 Feb 6 01:13 tmpqNMh9s
Actually, tmpdir is full of similarly named folders and files created at very similar times. At the time of error, there were only 131 GB of free space left.
I am wondering if "Permission denied" can mean something other than actually incorrectly set permissions, e.g. running out of space. However, the disk is "afs" which I don't have experience with - I am experienced only with use of chmod, hence the question.
