EMC Scaleio stuck rebuilding
Hi, we have problem with EMC Scaleio storage V2.0 . A day ago, one of SDS nodes was disconnected for short time due network error. ScaleIO detected it, and started rebuilding ~800GB of data. However it stuck at about 15GB and no rebuild is happening. I have tries to stop SDS service on affected node. ScaleIO rebuild remaining data, but these 15GB are still stuck.
There are 14 SDS nodes, enouth free space. We use 3 fault sets.
Any Ideas how to force rebuild ?
Thanks,

Hi,
Rebuild can get stuck for many reasons - see if there is any device reporting errors on any of the SDS - if yes, try to clear the errors and see if it progress. You can also try to switch MDM ownership, that should also kick the rebuild off.
Thanks,
Pawel

Can you please try to switch the MDM ownership to the slave MDM? This can force them to restart the stuck rebuild.
