ReadyNAS share consumed space always 0
I’m looking into why the NAS shows Data consumed as only reflecting the Utils share of 584Mb. The PsyData share uses 4.26Tb. It shows snapshots as consuming 5.67Tb and just over 1Tb remaining. I worry about deleting Snapshots as they're reportedly using space tht is plainly being used by Data.
I’ve got bitrot protection ON and have read that that can cause disk defragmentation over time, and also that setting a Quota for the shares might rectify the problem. UPDATE: Not only was I unable to set a Quota it's probably good that I didn't as another forum item "Re: ReadyNAS share consumed space always 0" not only fails to give a satisfactory resolution to this worrying issue but the questioner reported that they didn't have the "Data consumed = 0" issue until after they'd turned Quotas on and off!
I also see that Month end snapshots are retained >forever< under Smart Snapshot management so when the issue with the space consumed is resolved I will delete them manually at regular intervals, or see if I can setup a Smart schedule that doesn’t retain them forever!
Until I get an answer to this question I shall restart Resilio sync (it's been off while I've been trying to reduce space used, I deleted 200Gb yesterday but this didn't result in any increase in the available space) and wait for that to complete then will reflash the firmware (it's the latest, 8.8.0. Meanwhile this seems to me to be a serious bug that needs a definiite solution...)
Thanks, love & respect,

THE SOLUTION TURNED OUT TO BE DEFRAGMENTING THE VOLUMES
& possibly also deleting and turing off Snapshots first. Reflashing and Balancing operations do not help with this issue. From my diary:
18:18 I re-flashed the 314 f/w but (as I expected) that did not fix the Consumed = 0 issue. I saw that I had only deleted Snapshots for PsyData (the Share for which data used was showing as 0) but not for Utils. Misreading advice on how to do it manually I installed and got SSH (actually a more modern piece of code called ‘Gate One NT’ – it uses Python for example) working (I had to enable the SSH protocol then allow the admin user to use it) only to find that I didn’t need to ‘touch’ old snapshots as all of mine are post ReadyNAS OS 6.2 and that I could delete them manually in a very straightforward way. So I did, and that still, again unsurprisingly, didn’t make any difference to the Consumed bug. So I then looked into what Balancing does – it’s sort of like a partial defrag – so at 18:15 I started a Balance operation which is already 24% complete. I have a fair degree of hope that this, as it deals with the availability of metadata, will fix the Consumed error. Either way I plan to run a defrag…
During the Balance I realised that there were loads of Snapshots for the Resilio Sync share – I can’t imagine what they contain! Maybe how Resilio Sync is configured? Anyhow, I took the risk of deleting the lot >while< the Balance was still running, it seems to be OK with that. It’s exciting: the Balance is now 80% complete… Meh: BalanceFinished&DataConsumedStillWrong.jpg :( So I ran Defrag – and 19:13 at long last – perhaps because I’d disabled Snapshots (speaking of which https://community.netgear.com/t5/Using-your-ReadyNAS/Disabling-snapshots/td-p/955102 is wrong – there is no option to set the Snapshot Schedule to Never – what you have to do is turn off Smart Snapshot, and in Manual set the schedule so that all hours of every day are set to OFF – Day Off or Night Off - and I couldn’t work out how to let the forum know!) the Data consumed bug is gone and the NAS knows I have c.50% free – now to get on with converting .MTS files to .MP4 (that’ll save at around 1Tb)…

Are you seeing all your files in the main shares? If so, it is safe to delete snapshots.
Dear StephenB,
Thank you for that - yes, I do see all my files under the share that says Space consumed = 0 - I've backed everything up (c5Tb) just in case but your advice has given me the extra confidence I needed to actually delete the snapshots (I'm nervous as any problems is likely to mean doing a restore and as my backup is a home machine - a ReadyNas104 - it only sends data back to my main server at 10mbps - with Gigabit ports on my router I get c120Mbps from the 314 :)
I will update this post with what actually fixes the problem (e.g. deleting snapshots, reflashing or defrag).
Big Love & respect,
Psy <3
