CeeQuu, just to confirm, you don't have the issue when writing via FTP or SMB to directories outside of a pool?? If that's the case it has to be a mergerfs issue, right?
Hi,
Had time to run more tests. I'm pushing through Netgear Prosafe Gigaswitch, GS105 v4. I get steady 65-72MBs to my backupdrive in the same system as the merger pool, whole 30gb test file goes in with out hickups. its a 8tb drive with 1.2tb free so the 70MB cap might be drive space (or my workpc or OMV server hardware is choking.) I get from backup to PC a nice start of 112MBs before the buffers saturate and then a steady 90MBs rest of the way. Target drive on my PC is 1TB "random stuff never defrag" drive.
So outside the pool things don't bounce. With the gigaswitch i do get about 4gb burst before freeze pause. with the Asus AC68U i get about 2gb so somethings a bit different "direct" to OMV pool.
I also get this random "not enough space" with large files to some of the folders with both the backup drive and the pool. Pool has 2tb of free and backup 1.2tb so plenty of spave.
Pool is set mfs - most free space, as i don't care where in the drives data is spread.
MB on the server side FM2A88x e4 with Qualcomm® Atheros® AR8171, work PC is old (running x58 with a 6c xeon) and has a realtek 8111c chip with latest drivers.
EDIT:
Back at it.
Something kills the lines at OMV side, i think. I had a look at the various logs and i get link kills from all sort of things MiniDLNA reports unexpected link kills at steady pace, FTP bounces all over the place.
Attached a few pics. I don't know how to verify if its the qualcom or OMV that resets the links when enough stress is put on it with file transfers. Take a look at the FTP transfer log to see the way it bounces the link.
