[ScaleIO] Virtual disk bad block medium error is detected.
Hello all,
We got several [Storage Service Virtual disk bad block medium error is detected.: Virtual Disk X (Virtual Disk X)] logs in scaleIO server.
I believe this disk went bad and it caused unrecovered read error.
What I want to ask is, when I check [query_all_sds] and [query_sds], this sds seems to be healthy and all DISK seems normal.
Is this normal?
Also can you please let me know the details about monitoring disks in SDSs. Does MDM checks all disks in all SDSs frequently? or when SDC cannot connect to Disk, SDC informs MDM , then it changes mapping towards SDCs?
Thanks.

Could have just been a transient error, that the disk corrected. If all ScaleIO reports look fine, I wouldn't worry about it.
As for ScaleIO regularly checking the health of disks, look in the CLI documentation for "enable_background_device_scanner". It tells you all about it.
