Hi sa.taku,  if you don't have issues with your cluster and the DellEMC Support does not need a total log set with all dumps you can delete the dump files and core files with --clean-all or of course manually out of the /var/crash directory too. Memory dumps are created e.g. if there are failures or exceptions during booting a node. If you delete the files and after the next reboot there are new dump files you should open a SR to find the reason for the issue. Maybe there is something going wrong with the cluster...  If you want to keep all dumps and core files stored on the Isilon but want to exclude them of a new log set you can use the parameter --no-dumps and --no-cores.  Phil
Hi,  Our customer has a Isilon clustoer running in OneFS 8.0.0.3. And the size of isi_gather_info has been too big, almost 3GB.  I'd like to know how to reduce the size of isi_gather_info.  I found that the "minidump.tar" file in a node was 2.5GB. And I found a commnad option for isi_gather_info when Iread CLI administration document for OneFS 8.0.0.  --clean-cores  --clean-dumps  --clean-all  Which command delete the minidump file, and reduce the size of isi_gather_info???
How can I reduce the size of isi_gather_info?
