Bug#280213: exim4: Thinks it's always out of spool space

[John Goerzen]

Package: exim4
Version: 4.34-6
Severity: grave
Justification: renders package unusable

exim4 is giving 452 errors to all clients.  From its log:

2004-11-07 22:30:33 spool directory space check failed: space=0
inodes=4096

Yet:

erwin:/etc/exim4# df -h /var/spool/exim4
Filesystem            Size  Used Avail Use% Mounted on
/dev/hdc5             1.2G  905M  240M  80% /var
erwin:/etc/exim4# df -i /var/spool/exim4
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/hdc5                  0       0       0    -  /var

This is a reiser FS.

This makes Exim completely unusable on this system, since it absolutely
refuses to store any new mail.

Enabling debugging showed:

22:42:43 19164 SMTP>> 452 Space shortage, please try later

So you can see there is an issue.

This may be of interest, from Python:

s.statvfs('/var/spool/exim4')
>>> x.f_bavail
343762L
>>> x.f_bfree
343762L
>>> x.f_blocks
509885L
>>> x.f_bsize
4096
>>> x.f_favail
2760788L
>>> x.f_ffree
2760788L
>>> x.f_files
2770848L
>>> x.f_flag
0
>>> x.f_frsize
4096

So, you can see statvfs() is not at fault here.
