Drive Pool solution or something else? Alternatives? - Page 2

Your desire for both is your problem. You can't have it. If you want drive pooling, something must enforce you don't have two files on different drives with the same path. You have to give up manual control; you can no longer treat the physical drives as individual volumes because they aren't independent anymore.

The reason DFS wasn't working for you was because it is designed for distributed systems, to give the users a unified view and give sysadmins a geographically partitioned view. You had all the shares on one host..not distributed. To use DFS to fake what you want, install AD and HyperV on your server. Make one HyperV guest for each drive (use Server Core here). Put each guest into a different AD Site. Use DFS to merge them all. It's doable, but probably not worth it just to shoehorn Windows into a role for which it is not suited.

False. You certainly can have it. Obviously it is trivial if you do not have identical path/filenames on different drives (which is certainly the case for my media pool). If you do have identical path/filenames on different drives, then it is straightforward to have a rule that, for example, always points the symlink to the "first" occurrence (or "last", or some other rule). That is not ideal, but it just means you should avoid making identical path/filenames with this type of pool, not that it is impossible to do what he wants.

Of course, it may be very difficult to manage on Windows. But it is quite easy on my linux box.

Linux has VFS. Windows does not. You can easily add layers in the middle with Linux, but with Windows you have to run around catching butterflies filesystem events. That's why I think all the FooRaid software for Windows is crap.

DFS solves this deficiency at the larger scale, but it's not a solution for a single server.

Anybody can confirm if it works on Windows OS?
Thanks.

Just a thought, but change your management and thought process to suit how the software actually works.

Most media/file shares only need to be read only for ALL users. Then simply have a folder that has read/write access for users to share content or add new content. Once a week (or whatever schedule fits your needs), move content to be kept from the shared folder to its home on the read only drive. It's basically what you are doing now, without the need for using accounts and permissions to set access for all files/shares/drives/pools/whatever. The only data that can lost or corrupted by the users is the small amount of data in the open access folder.

Just my two cents.

This is not directed at anyone in specific, but it's just common sense to keep access privileges as low as possible, there are many many reasons why you would want your pool to be read only. Apparently yet another reason has surfaced earlier this month: there is new malware/virus that is circulating on the net that encrypts your files and demands ransom to unencrypt them. The current going price is about $2000.

So guys, stay cool, stay safe.

 

I'm still testing DrivePool + SnapRAID combination by removing hidden and system attributes of PoolPart.GUID folders. I have created a batch file that removes hidden and system attributes from PoolPart.GUID folders, runs SnapRAID sync and scrub 6 days a week at midnight. I have created another batch file that is similar to the first one, but it does full data check instead of scrubbing, that one will run only once a week at midnight.

 

On my to do list are:
- Test SnapRAID file recovery by doing a test delete of one of the files, I have been too busy to do it, but it has to be done
- Find a good way to log the batch file results into a text log file
- Find a way to email me the results

How about mounting each drive as a folder to the master drive? Then use SnapRaid only for parity of the master and mounted drives?

How has your DrivePool + SnapRaid experiment worked? I have Drivepool installed and I really like it and the scanner. Now I'm trying to get SnapRaid working on top. However, as you have found out SnapRaid can't recognize the hidden folders of DrivePool. Any suggestions?

Wouldn't work because 1) it does not solve the hidden folder problem, and 2) I'm not sure how SnapRAID would handle mounted drives inside master drive, theoretically I think you can point SnapRAID to individual folder on each drive if you do not want to protect entire drive, but once again, I am not sure how SnapRAID would handle it. Basically I think this idea is a non starter because one, I'm not sure if SnapRAID can handle it, and even if it did, it does not solve the original problem.

Yes, I'm still using it, it works just fine. Yes, DrivePool data folders have 1) hidden and 2) system attributes applied to them, so in order for SnapRAID to recognize those folders you need to remove hidden and system attributes from them. So once you do that SnapRAID will recognize those folders, and fortunately Stablebit Drivepool does not reapply hidden/system attributes once you remove them. I used attrib command to do that. I'm not at home, so I do not remember the exact syntax, but it should look something like this:

 

attrib -H -S D:\PoolPart.GUID /D

 

I actually created a couple of .bat files that remove hidden/system attributes from PoolPart.GUID folders just in case StableBit DrivePool decides to reapply them, and then run either snapraid sync or check command. I just migrated my fileserver to a new box so I still have to set up nightly jobs running those .bat files, but once I do it's going to be leave and forget kind of operation.
