Thank you for your answer. Here more details:
- Bootloader: XPEnoboot_DS3615xs_5.1-5022.1.iso
- DSM: DSM 5.1-5022 Update 5
- MicroServer HP (I dont remember the exact model but using 4 virtual disks i don't think the issue is in the HW configuration) with OS ESXi with 4 with 4 disks SEAGATE Barracuda 1TB, ESXI 6.0.0. I have other machines on that ESXI and none of theme are running into any kind of disk issues.
- The exact message is: Abonamality detected on Synology station. All volumes have been unmounted.
Some other times the message maybe is not the same but it is always related to disk issues
in this specific case I received this error after applied the DSM 5.1-5055 update
Many thx
