This is/was rather odd since we, until recently, had massive amounts of available space. So after digging around some, I found /opt/zimbra/zmstat to contain 3.1 TB (!) of ... well, "junk"
As per this article:
https://wiki.zimbra.com/wiki/Purge_old_zmstats_data
I ran:
(I still don't know how to set "zmstat_max_retention", but that's another story)/opt/zimbra/libexec/zmstat-cleanup --keep 700
Well, this removed some quite old statistics, but unfortunately, the main issue is still here:
I really don't care much for this data over time, unless we're troubleshooting something. Then, and only then, may it be interesting with some "over time" data.1,3T ./vm.csv
979G ./io-x.csv
861G ./io.csv
7,1G ./io-x.csv.gz
6,4G ./io.csv.gz
5,8G ./vm.csv.gz
So how do I (safely) remove/truncate these files?
