Hello,

Please help me. Sorry for my english.

Before I performed live migration many times, but today after migration windows report about many error on disk. After reboot vm chkdsk found and fix many error. I lost data and restored vm from backup.

Before I had only one (or may be two) similar problem with live migration for 5 year using PVE.

Please say me which conditions for safe live migration?
If I set disk cache write-through. Is more safe?
