There were four VMs ( 3 Linux & 1 Windows ) found file system corruption and caused company's application failed in this month. In linux guest OS, I need use FSCK command to fix file system. And in Windows server I lost ntoskrnl.exe file and need to use chkdsk to fix file system. I have checked server and storage hardware, but there is nothing error found.
Anyone could give me some idea about this problem? We are running Dell poweredge server and Huawei-Syamantec iSCSI storage.
