File Transfer problems
I am currently runing a Readynas ultra 6 plus with 3 6TB and 3 3TB WD Reds via windows 10 pro, the PC is running i7 intel second gen with 16g of ram. The problem i'm having is if I transfer files lar...
- Apr 12, 2021Thanks to everyone that helped. I have now upgraded to 4gb of ram and that has now helped my file transfer problems. Thank you.

How much RAM is in the NAS? it is still running the stock amount 1GB
You may want to open an SSH session up the next time Will do that if I knew how?
Are you performing a volume balance somewhat regularly? I have never done that, ever.
Thanks for the advice.

You may also wish to look at RAM usage.
If you have quotas enabled on the volume and lots of snapshots that can use a lot of memory. With just 1GB RAM I'd recommend disabling quotas on the volume and also using a custom snapshot retention policy if you wish to use snapshots to ensure that only minimal snapshots are kept.
I rarely, if ever balance my data volume, so I differ from some here in thinking that balancing is recommended far too often. The NAS automatically returns empty chunks to unallocated space. If your volume was to get full enough to benefit significantly from a balance you'd need to free up space first anyway.
With 5+ TB of storage space free there should be plenty of unallocated space but you can easily check that in btrfs.log.
Note it's important what percentage you have free rather than the raw amount (5TB free on a 100TB volume is very different to 5TB free on a 19TB volume). With your volume you probably have about 25-30% of the capacity free which is a decent amount.

What disks are you using? If this issue happens only when writing to the NAS, then you might be using one or more SMR drives (your symptoms sound consistent with that).
- bolterMar 01, 2021AspirantThanks for the suggestion, but all the drives are WD CMR reds. After reading a few suggestions, I think I will try upgrading my ram first as DDR2 ram isn't that expensive anymore. Only problem is, the ram I have found states it is only for AMD yet all the specs fit the specs for the readynas. Buying this type of ram in Australia is hard to find.

- WD20EFAX (2TB)
- WD30EFAX (3TB)
- WD40EFAX (4TB)
- WD60EFAX (6TB)
The WD Red Plus and Red Pro line are CMR.
