Corruption in sharepoint 2013

Question

We have a share point 2013 farm with 2 nodes. There are 64 web applications in one node. 2 weeks back when we tried to create another HNSC web application it corrupted the whole system and all our sites were down. We had to restore back the entire machine to get it to work. Has anybody faced this issue before? If so what is the root cause for this and remedy. Thanks in advance for any help Rajesh

There were actually 2 mysteries here which likely lead to my trouble figuring this out. Nothing was actually corrupted just an inexperienced user and an inexperienced admin coupled with some slightly strange behavior in SP. The first mystery that of the phantom files was caused by SharePoint marking most of the uploaded files as checked out to a user but without any checked in version. SP did not show them but it did count them in the ItemCount property of the library. My understanding at this point is that this was caused by bulk uploading of files through explorer. The second mystery I'm still a little confused by. The original AllItems view actually existed in the library's views collection but it had been marked as hidden and the title had been blanked. I'm not sure how the user set it as a hidden view from the UI (I haven't yet found the button to do that) but I was able to restore the view by setting the hidden property to false and assigning a title to it. The invalid URL listed in the library if there are no visible views I'm guessing is a bug especially given that the cancel button in the library properties redirected me to a totally different site collection but at least it's easy enough to remediate. Hopefully this information will help the next confused SP rookie admin to try to avoid thinking SP has gone completely off the rails.
