I guessed as much, it was half feature request, and half checking with the forum that I hadn't missed a checkbox in advanced settings to enable it.

I have 12 large drives (each 18TB+). I have multiple 10s of TB of data on them. I have just turned on duplication, and I can see it is duly duplicating away.. but it is copying one file at a time. so duplicating a file from drive 3 onto drive 8... then duplicating a file from drive 5 onto drive 11, etc. Is there a way to get it to duplicate in parallel ? it could be duplicating files from drive 1 onto drive 2, AND from drive 3 onto drive 4, AND ... etc etc... several simultaneous copy operations. at the moment it is going to take an extremely long time.

My main issue AGAINST storage spaces is that the underlying disks dont show up in stablebit scanner anymore it must be possible since HDD sentinel can still show/test the individual disk data

This was only true in Server 2012, since 2012 R2 (for the last three years....) it can fix corruption in parity pools too https://technet.microsoft.com/en-us/library/hh831724(v=ws.11).aspx

Okay dokay, i wont put scanner on that machine yet then! Thanks Chris

but would it be scanning the underlying disk - or would it be scanning the storage space? I have a couple of thin provisioned volumes on my space

OK, thats great, the sooner the better! I've got a 10 drive storage space and at the moment i cant even monitor the drive temps, but i'd love to have the re-assurance of a monthly surface scan on them too

Hi, Im just wondering if there is an update on getting SMART/individual disk info through a storage space? I know its possible because Western Digital's drive diagnostics still see the individual disks which comprise my storage space. Thanks Chris

How can it scan the whole disk is it has areas unaddressable by the operating system though? The Seagate archive drive is 8Tb shingled + an additional 20Gb non-shingled used for writing / temporary storage while re-shiningling at any given time that 20Gb non-shingled slice could be mapped to any of the shingled blocks on the 8Tb disk. so if you check a block is readable, how do you know whether you are getting the shingled block or the temporarily-mapped non-shingled one? (and obviously missing the other) since all of the block virtualisation is handled within the disk. maybe an 8Tb block is unreadable .. but at the moment scanner asks for it , there is some hot data sitting in the 20gb storage space waiting to be written to the shingled area and it gets that instead?

not "Useless" but there may be areas of the drive not scanned.. because they arent accessible

true... but the 20Gb of space which isnt shingled.. doesnst actually count as part of the disk... in terms of capacity.. so if its already moved everything out of the 20GB and onto the rest fo the disk, then if you scan EVERYTHING.. it wont scan that 20GB... and vice versa.. if some stuff hasn't been moved to the shingled area.. then when you scan those blocks you will get the non shingled ones and it wont scan the shingled area

hey Chris, Since he's bought the Archive Drives, and we are talking about surface scans.. how does scanner handle the address virtualisation of archive drives (or doenst it?) i.e. when you scan a certain block... how do you know if its the same block as last time? or if its been virtualised to the non-shingled area by the disk?

Nothing happens when i do that, even after a reboot, files which don't show up in the file list still don't show up. I'll have to wait for it to happen again since I've already "fixed" this one by copying the files off the individual disk and then copying them back to the pool

Hi, They are showing up when i search the individual pool part folders on the individual disk mount points... they do not show up in the pool at all, either in file lists or in search. There's no antivirus or disk tools or other filter drivers (we checked all that when i had my previous issues with metabrowser) I can enable logging, but what do you mean by "refresh the file list" ? Thanks

I have a large pool.... sometimes, rarely, but more than once, i have copied a movie to it.. and then when i've gone to find it.. it wasnt there! If I manually search the individual mounted disks.. The files are on the individual disks.. but it doenst show up on the pool. See screenshots attached If I copy the file back off the individual disk and then copy it onto the pool, it will then show up. I've tried "re-measure" but that doesn't make it re-scan the disks to find any files which have gone AWOL. 1) any idea what/how this happens? 2) how can I get it to scan all of the disks and have all of the files in the pool part folders appears in my pool? I'm now a bit concerned about how many files might be "missing" in this way! (I'm using 2.2.0.628.BETA) Thanks Chris

I'm not sure what your actual arguement is? That NAS drives are overpriced? I've had maybe 20 drives fail on me over the last 10 years, they are always about 40C... I'd rather pay slightly more for the longer warranty - most consumer NAS drives have 3 years, most desktop drives 1 or 2 for the last year I was mainly using WD 6TB Reds (+£5 for an extra year warranty) - what cheaper "desktop" alternative would you suggest?

I've got 30 disks I'm not about to start storing 30 empty cases..., or trying to keep a record of which disk belongs in which case I'd imagine he simply threw away the case and he says in his post that its obvious that the drive has been removed.. so i suspect that there was some damage done to the case

I was trying to find.. but cant: When (recently) WD released the new 6TB Red Pro, one of the review sites made a great table using the (sometimes unpublished) information about the various WD drives and comparing the Blue/Black/Green/Red/Red Pro/Re+/Re/Se models and what you got extra at each step aside from TLER and the NAS oriented firmware, the Red's do have better/more efficent motors than the green / blue (which are designed to run 8 hours a day, not 24) While you need Red Pro or high to get actual hardware vibration sensors on the circuit board, the Reds are able to measure and adjust for the kind of vibrations you get in an array, which the desktop models cant do there is more to it than just the warranty

I'm the same... I previous shelled drives when the externals were inexplicably cheaper than the internals; despite it being the same disk with some additional haradware, but then you lose the warranty I've got 12 enterprise 4TB (I got a good deal) about 14 Red 6TB - but i've got 4 year warranties on those and a few Seagate 8tb ones

haha, thats no fun i'll have to see how much i get up to at christmas.. need to duplicate that other 40TB!

I meant I wanted screenshots of someone with a 246TB pool I'm curious to know how many disks he's got and what they are all attached to and housed in ive also got a spreadsheet with all my drives (and their warranties) I was lucky to get a bunch of 4TB WD datacentre drives cheap off ebay that still all had the full 5 year warranty (and they are screaming fast)

have you looked at the 8tb drives? since they are shingled, they work out to be cheaper per TB than the 5TB ones (here at least)

Yes, where ever possible they are simply rips even the 4GB/episode stuff looks blurry and soft to me, compared to the 8-12GB/episode bluray rips yeah.. in terms of DP plugins I've only got the scanner, SSD, and space equalizer on. I've told the SSD plugin it can let the drives get to 100% full.. so hopefully it will only let new files get added to the very fast disks then the space equaliser should move stuff in the background so all the disks are filled to the same percentage

lol, yeah screenshots! Ive also got four of the 8tb drives (maybe 5.. I lose count! ) hahaha

Yes Chris, definitely slacking! however I haven't just hijacked the thread for no reason! I have 12 very fast drives... 12 slowish drives.. and 6 archive drives (deathly slow for writes) Can I set it up so that new files written to the pool ONLY go onto the 12 very fast disks and then in the background the balancers make sure that all 30 drives stay the same % full? I assume I need the SSD plugin, but there seem to be too many options. help please! hehehe
