dvd.collector Posted October 16, 2015 Share Posted October 16, 2015 Hi all, am trying to understand why my unraid server is currently running really slowly. Its hard to say exactly when this started, but it could be from the latest release. One thing I'm noticing is that accessing my server whilst the move is running is almost impossible. Windows just hangs when trying to even list files in a share. So I started monitoring the console and see the write count increasing on 4 disks at the same time (excluding parity) whilst the mover is running. Is that to be expected? I'd assumed one file copied at once (this is what the log seems to show), so why writes to multiple disks? I also notice from running the drive testing script that one drive (disk seems to be slow, however the slowness of the server in general seems to still be there even when not writing to this disk.

BRiT Posted October 16, 2015 Share Posted October 16, 2015 Are you running cache dirs? Were the drives sleeping when browsed by Windows? What are your folder explorer settings, general files or media or music or automatic? Do you have spinup groups enabled? What shares are being used when moved? What are your share settings and thresholds? What are your disks min free space settings? No one can answer your question unless you provide more details. Quote Link to comment
dvd.collector Posted October 16, 2015 Author Share Posted October 16, 2015 Are you running cache dirs? Yes Were the drives sleeping when browsed by Windows? Some were, but the ones being accessed by the mover were spinning (according to the GUI) What are your folder explorer settings, general files or media or music or automatic? General Do you have spinup groups enabled? No What shares are being used when moved? Just one share called TV Series What are your share settings and thresholds? Set to High water (is that what you mean?) What are your disks min free space settings? set to 0kb (default?) Quote Link to comment
