Description Javier Bahillo (mail address dead) 2015-05-25 09:18:51 UTC 
When defined a max log size for samba:
max log size = 100000

it looks that samba process keep file descriptors open for samba.log.old even if that file has been deleted:

In worst cases, this might led to usual tools like df to report filesystem  being full, while it is actually not (just because of file descriptors being opened - restarting samba will close those descriptors and workaround the issue)
