Ok, I did the compact on 1 osd.
The utilization is back to normal, so that's good... Thumbs up to you guys!
We learned the hard way, but happy to spot the issue and share the info.
Though, one thing I want to get out of the way before
adapting the other
OSDs:
When I now get the RocksDb stats, my L1, L2 and L3 are gone:
I guess that they have all been merged now. On a OSD with L0 and L1 I
see L0 disappear after a compact. After a restart, recovery, and then
dumping stats again it's there again. So yeah, it gets created
automatically.
We use the NVMe's to store the RocksDb, but with the spillover towards
the spinning drives.
L4 is intended to be stored on the spinning drives...
Will the other levels be created automatically?
Yeah pretty sure that's how RocksDB works, and tested that (see above).
