[SOLVED] Can't run script after hard disk was filled

pljvaldez · 12-13-2010, 10:38 PM

I have a MythTV backend setup with videos also transcoded to a directory for streaming to my Roku frontend. A week ago, the backend had an issue that caused the hard disk to fill up, which borked a bunch of things up. I've since repaired the damage (and learned a lot about log size settings for logrotate.d). Anyway, my last problem is that a script I wrote to compare the files in the transcoded directory to the MythTV base directory and delete files no longer relevent doesn't work anymore. I get the following error when run by any user, including root:

Code:

bash: ./roku-autoexpire.sh: /bin/bash: bad interpreter: Permission denied

The script worked fine before the hard disk fill, but now I can't seem to get it to work. Both the original MythTV partition and the streaming partition are XFS. Here's the pertinent lines from fstab:

Code:

/dev/sdb1       /var/www/mythroku       xfs     defaults,auto,grpid,exec,user   0       0
/dev/sdc1       /mnt/mythtv     xfs     defaults,exec,user      0       0

Permissions for the directories are the following:

Code:

drwxrwxr-x  2 mythtv mythtv 16384 2010-12-13 19:21 /var/www/mythroku
drwxrwxr-x 2 mythtv  mythtv   20K 2010-12-13 20:13 /mnt/mythtv

Any ideas on where to begin? I tried fiddling with the mount options for the partition, but that didn't seem to solve the problem.

Have you had a look at the file /bin/bash to see if it:
a) exists
b) has at least executable permissions, I don't know if you'd need any others; you could set it to 777 temporarily just to see if it fixes the problem
c) works as you would expect

I did check \bin\bash and even wrote a quick script to touch file.txt. It works in ~ but not on the /var/www/mythroku directory. I CAN just run touch file.txt from bash in that directory. But if I put it in a script it fails to execute. So I think this is a mount/permissions issue related to execute permissions, but I can't see the problem.

And I assume

Code:

echo $SHELL

returns /bin/bash as you'd expect, even from that directory? And have you tried installing another shell, like zsh, then running

Code:

cd /var/www/mythroku
/bin/zsh #prompt should change to zsh default
/bin/bash #prompt should change back
exit; exit

I only propose installing zsh so you can actually tell if it's running /bin/bash properly from the mythroku directory, you might be able to think of a better way...

I fiddled around with the fstab line some more and just set it to "defaults" and remounted the partition. It appears to be working now. It's weird to me that xfs doesn't take all the normal mount options of other linux filesystems. Thanks for the help.
