/u01 filesystem filled up
Running a X5-2 ODA with 2 RAC nodes, database version is 12.1.0.2, grid version is 18.3.0.0. and linux is 4.1.12-124.18.6.el6uek.x86_64 #2 SMP Wed Aug 15 19:15:35 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux
Currently running 70+ databases in a load balanced way. Also have flashback enabled.
Just had an issue where our /u01 filesystem started to "fill up". In fact it took only 5 mins and it was 100% full.
during this time I was deleting old trace files and trying to see where the large file(s) were located. I didn't find any.
When I looked at 'top'.... one database stuck out so I started the database instance on our 2nd node and stopped the instance on the first node.
