A couple of days ago, one of our file servers running server 2019 had a lockup, and upon rebooting it, a number of files (over 90%) in a shared folder seems to be corrupt. I've since done a restore, and they seem to be fine again. The error message (which i can't remember exactly off the top of my head) was the one where it says SYSTEM can't access the file (i can find the exact error message). I couldn't delete any files, nor could i restore over the top of them. The weird thing is, it was only one folder share that was corrupt. The drive contains three other shares, and they all seemed to be fine when i checked them over, so it doesn't appear to be a drive issue. It is a virtual server, running on VMware.
I need to try to get to the bottom of what caused them to corrupt, and was wondering if there is anything specific in the server logs i need to looks for. I can see some errors in the logs at the time that it happened, but not sure if they are related or relevant. One refers to having I/O errors, which seems to be relevant, and the others appear to be related to windows search.
Is there any specific places within the logs which will help me work out the root cause of the issue?
I need to report back as to the cause of the issue, and need to ensure that it's not going to happen again.
