NTFS Corruption on ISCSI volume - Multiple hosts accessing save NTFS iSCSI Volume

We are experiencing NTFS corruption on an ISCSI mounted volume. We accidentally mounted the NTFS iscsi volume on another server for about 10 minutes. Upon realizing the mistake we logged off the iscsi target on the second server. We restarted the primary server to run chkdsk and realized the data was missing. We can see the drive but it shows that it is empty.

We are currently running chkdsk /f /r to see if that fixes the problem.

While we wait I want to know what other tools can we look at to restore the data?

The chkdsk /f /r seems to have worked. Is it highly suggested that we copy the data out, and reformat the  drive before using in production? We are fighting against the clock to get this to work before production hours. We are considering just running 20 minutes snapshots throughout the day to buy us one day. Is this is a significant risk?

You should not need to take those steps.  A good backup (snapshot or otherwise) is a good idea, but as long as you don't mount it again while in use, you should be OK.

So as long as chkdsk completed and we can see our data we can safely use the data? Our plan is to use the data on the "dirty" disk for one day and then in the next evening copy the data to another volume, reformat, and then copy back to ensure that we are working with a clean disk

rspit / rsp_it,

It appears you are using two different accounts.  I will assume the two accounts are the same entity and answer as though the Author is asking clarifying Questions, not another Expert chiming in....

Again, if the chkdsk completed, you should be fine.  I would do either a backup or a snapshot now, but only as a Just-in-case scenario.  Just be sure you don't double mount it again. :)  You can't always recover from that.
