Another happy user of Drivepool with a question regarding NTFS compression and file evacuation. A few days ago I started having reallocated sectors counters on one drive. Stablebit scanner ordered drivepool to evacuate all the files, but there was not enough space so some of them remained.
I bought another drive, which I added to the pool, and tried to remove the existing one, getting an "Access is Denied" error. Afterwards, I tried to force evacuation of files from the damaged drive using the appropriate option in the Stablebit scanner. This triggered a rebalance operation which was going very well, but then I notice several hundreds of GB marked as "Other" not being moved.
Then it stroked to me that the new drive has some files without NTFS compression, whereas the old drives in the pool did have. I think somehow since the checksums are not the same for compressed and uncompressed files this is somehow confusing the scanner. What I did so far (for consistency at least, hope this doesn't make things worse!!!) is to disable compression from all the folders I had it enabled (from the old drives, including the faulty one) and wait for the rebalance to complete.
Is this the right approach? Is this also expected to happen when using NTFS compression? In drivepool is actually not worth the hassle to have it enabled? (I was getting not fantastic savings, but hey! every little helps, and wasn't noticing perf. degradation). Hope the post somehow makes sense and also hope my data is not compromised for taking the wrong steps! Thanks!
