gerrit disk was full

Just now the gerrit disk quota filled up. It hit the limit at 7.6G disk usage. I gave it 10G of space via zfs to not get pulled in too deeply, we may want to investigate whether anything filled it up unintendedly/erratically. When I look at the listing I made when writing https://osmocom.org/projects/osmocom-servers/wiki/Osmocomorg_Web_Servers gerrit already had 7.19 G disk usage then. It seems some snapshot may have filled up the rest now, and the remaining 400Mb are from new commit objects / repos repack? It's too late now for me to wait for a du to complete... ~N
