rbh-report -S stopped working #101

Hey @tl-cea, I use rbh-report -S to split file class reports by user AND group and this command stopped working a few days ago I'm not sure why:

[root@oak-rbh01 scripts.d]# time rbh-report --user-info  -S  -C stanford+groups+nosnap
Using config file '/etc/robinhood.d/oak.conf'.
filter class: stanford+groups+nosnap

real    7m52.198s
user    0m0.004s
sys 0m0.002s
[root@oak-rbh01 scripts.d]#

It just displays nothing anymore for this particular file class filter.

If I remove -S, the command works fine:

[root@oak-rbh01 scripts.d]# rbh-report --user-info -C stanford+groups+nosnap
Using config file '/etc/robinhood.d/oak.conf'.
filter class: stanford+groups+nosnap
      user,     type,      count,     volume,   spc_used,   min_size,   max_size,   avg_size

Version: robinhood-lustre-3.1.4-1.lustre2.10.el7.centos.x86_64 Any idea on how to troubleshoot this? Thanks!

Ok closing as this problem was due to MySQL's tmpdir being too small to handle some temporary tables when -S was specified, but not due to an issue with robinhood itself. I fixed it by changing tmpdir to a larger volume.
