[Check_mk (english)] check_mk-df crashes

Hello,

For various reasons, we cannot use OMD, so I stick to 1.2.8p27

I have a crash in check_mk-df (bomb) I ran the precompiled file for the
host with appropriate options :

python /var/lib/check_mk/precompiled/racvision.py -v
Check_mk version 1.2.8p27
[(u'/', 6134.0, 4231.87890625)]
FS / UNKNOWN - check failed - please submit a crash
report!
[(u'/boot', 476.205078125, 284.8017578125)]
FS /boot UNKNOWN - check failed - please submit a crash
report!
[(u'/var', 3062.0, 1854.5703125)]
FS /var UNKNOWN - check failed - please submit a crash
report!
[(u'/var/log', 2038.0, 1981.91015625)]

report!
[(u'/var/log/audit', 508.66796875, 480.31640625)]
FS /var/log/audit UNKNOWN - check failed - please submit a crash
report!

The -d option helps :

python /var/lib/check_mk/precompiled/racvision.py -d
[(u'/', 6134.0, 4231.87890625)]
UNKNOWN - Exception in precompiled check: need more than 3 values to

The output of cmk -d :

The agent and check_mk are the same version.

Thanks for any clue

Well, I tracked down the problem, it is here :

def df_check_filesystem_list(item, params, fslist_blocks, fslist_inodes
= None):
if "patterns" in params:
[...]
else:
for idx, (mp, size_mb, avail_mb, reserved_mb) in
enumerate(fslist_blocks):
[....]

fslist_blocks does NOT contain reserved_mb, it contains only 3 members
[(u'/', 6134.0, 4231.87890625)]

Hi,

My mistake, I wasn't the original maintainer of our home-made package,
and there were a patch for an old version remaining...

Sorry for the disturbance
