We just moved to new Ubuntu servers.

We use file-column (with some modifications) to deal with our file uploads.

deploy@jgp-web01:/var/www/oursite$ ls -l public/uploaded_file/file_name/000/000/051/585/ 
total 4
-rw-r--r-- 1 gerhard www-data 2670 2008-11-15 05:09 MatthewJacobsCV.txt

deploy@jgp-web02:/var/www/oursite$ ls -l public/uploaded_file/file_name/000/000/051/585/ 
total 4
-rw-r--r-- 1 deploy www-data 2670 2008-11-15 05:09 MatthewJacobsCV.txt

If you look carefully, you’ll see one is owned by “deploy” and the other by “gerhard”.

These are mounted by NFS, shared across the two computers.

So these are actually the same file, but with different permissions on each.

A quick use of the “id” command confirmed this;

deploy@jgp-web01:~$ id deploy
uid=1004(deploy) gid=33(www-data) groups=33(www-data),1005(aspire)

deploy@jgp-web02:~$ id deploy
uid=1002(deploy) gid=33(www-data) groups=33(www-data),1003(aspire)

The answer is;

root@jgp-web01:~# usermod -u 10000 deploy

root@jgp-web02:~# usermod -u 10000 deploy

boom!

Now this is resolved, but you’ll have to chown all the existing files, back to `deploy`, else they’ll still be attached to the old uid.

UID problems across a shared mount?
