Snapshot of a virtual machine failed because it was unable to quiesce an application
Hi Everyone,
Just wanted to check if anyone has found the root case of this issue.
The VM backups are failing intermittently with following error:
0xe000959a - An attempt to take a snapshot of a virtual machine failed because it was unable to quiesce an application.
V-79-57344-38298 - An attempt to take a snapshot of a virtual machine failed because it was unable to quiesce an application.
VM level backups are configured through Vcenter (Version 6.5)
We have also found the following error on Application event viewer of failed VM at the time of failure:
Evevt ID: 12289, VSS
Volume Shadow Copy Service error: Unexpected error DeviceIoControl(\\?\fdc#generic_floppy_drive#6&2bc13940&0&0#{53f5630d-b6bf-11d0-94f2-00a0c91efb8b} - 00000000000004C8,0x00560000,0000000000000000,0,000001B95E0F2080,4096,[0]). hr = 0x80070001, Incorrect function.
