Hi all.
I´ve a problem accessing files on a iscsi disk served by a QNAP NAS.

The NAS is using RAID5 and all hardware is ok. We have an iscsi drive with 4TB mapped to the server.
In the mapped drive we have a directory with about 8.000.000 files and about 1.000.000 directories. The files are all PDF, JPG and HTML and vary from 100Kb to 1Mb. All other files and directories are ok.
As the drive was full we tried to access it to clear some space. Doing that I learned that the free space on the drive was near zero but there’s only one directory when there should be a million...
I’ve tried chkdsk but I get an error after a couple of hours stating it failed because there was no free space.

I believe the files are all there because the space is occupied (the disk is still full) and there is no fisical damage on the disks. It´s a new NAS (3 months).

I believe the problem is ot the file system structure. Can anyone help? The ackup is incomplete...

Consult Data Recovery Professional as RAID cases are not that simple.
From our experience in most of RAID drive crash, data is lost not due to original problem but it is lost due to experiments. Due to Redundancy, RAID 5 data is recoverable even incase of drive failure.
