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
