Hi all,
strange things happens to me and I would like to avoid it to the future, but I am not sure, what caused it and how to prevent.
I get corrupted VHDX file, where MSSQL DB was placed. The VHDX was 15 GB dynamic drive, where only 10 GB has been used. The drive has been located on CSV (HP 3PAR over SAN) with many others files (cca 200 VHDX, more than 60 VM running without problems).
- no VM crash or reboot
- no VM live migration
- no storage migration (HP 3 PAR, no ODX)
- no one logged in on the VM
- no application log error or warning
- no system log error or warning
- nothing special audited in the security log
- no antivirus or backup running at the time
- no special scheduled jobs
The drive simply become "Not Initialized" for the VM and for other systems the VHDX seems to be corrupted and unreadable.
Q1. how to fix (the file cannot be mounted, converted, edited or inspected)
Q2. how to track down the root case
When the problem occurred first, we simply initialize the drive, create new partition and format. Suddenly one week later we get the same issue at the same time :(
