The most recent check_netapp_pro code release includes 2 important bug fixes which users might like to test. The first relates to call- and store files getting too big and the second to VolumeAutosize crashes on some volumes. Both bugs are fixed in the RC and next major releases.

1. The call files were sometimes reported to be too large. After investigation it transpired the –store-descriptions parameter was being ignored in certain
cases.

$ ls -lh /.../calls/10.242.106.71
total 6712
-rw-r--r--  1 ila  staff   385K 22 Nov 16:59 volume_history.143912378.call
-rw-r--r--  1 ila  staff   387K 22 Nov 17:03 volume_history.143912605.call
-rw-r--r--  1 ila  staff   387K 22 Nov 17:29 volume_history.143914188.call
-rw-r--r--  1 ila  staff   124K 22 Nov 18:21 volume_history.143917294.call
-rw-r--r--  1 ila  staff   122K 22 Nov 18:22 volume_history.143917375.call

The code was modified at approx. 18:00 and the size difference are clear to see showing the bug being fixed.

2. The VolumeAutosize was an issue for the newer 4.0 released codebase, where we unexpectedly encountered undefined values from the nodes themselves.

$ ./check_netapp_pro.pl VolumeAutosize -H $HOSTNAME -w =MAX/100*20 -c =MAX/100*10 ...
Use of uninitialized value $X0N20 in string eq at .../checks/VolumeAutosize.pm line 123.
Use of uninitialized value $X0N21 in subtraction (-) at .../checks/VolumeAutosize.pm line 150.
Use of uninitialized value $X0N22 in subtraction (-) at .../checks/VolumeAutosize.pm line 150.
Use of uninitialized value $X0N29 in concatenation (.) or string at .../lib/Il/SysMon/CheckPlugin/Metrics.pm line 594.
Use of uninitialized value in substitution iterator at .../lib/Il/SysMon/CheckPlugin/Metrics.pm line 931.
The threshold-formula '/100*20' evaluates to nothing.

The fix in this case was related to a value being checked for true or false, and taking a non-relevant default value in certain cases. A workaround would be to discover hosts where autosize-is-enabled=n/a using –explore and to then remove them from the checks by using the –exclude parameter.

These fixes will ship with version 4.1.0 However, if you need these fixes urgently, or would like to test the release, the RC 4.0.2_02 includes both the fixes and is already available for download.
