It has happened two times, each one after a clean reinstall and a wipe of the old fs. In less than a day, both installations got corrupted and the filesystems went readonly. When listing the contents, I saw many directories with question marks. My system has 4 drives and 2 fs: - 1 SSD in single - 3 HDD in RAID1 I do readonly snapshots every hour of all the subvolumes, so I have hundreds of snapshots. Now I'm back in 3.16.4 without any problems. I'm trying to reproduce my setup in a virtual machine. If the corruption happens again, I'll send you more data on this problem. -- Juan Orti https://miceliux.com
