Hi,
We have experienced a double failure - during a replacement operation of our UPS(s), while the secondary UPS were offline, our primary UPS experienced a power glitch and took down our development/test clustered servers. Upon recovery, all disk volumes came back up okay but one of the drive is now marked as 'Unknown'. Here is a quick background settings of what we have:
OS - 2x identical test servers running Windows 2016 Standard in a 2 nodes failover cluster configuration
Clustered Role - SQL 2017 only
3 Volumes - mounted using iSCSI to a Synology NAS (RS3614xs+) [This is for our Test/Development Environment so we can see what we need to do for our Production Environment]
1. Heartbeat = Formatted using ReFS used as Disk Witness in Quorum (Raid 10 Array) - no issue post power glitch
2. SQLLog = Formatted using ReFS as SQL Log Petitions (Raid 5 Array) - no issue post power glitch
3. SQLData = Formatted using ReFS as SQL Data Petitions (Raid 10 Array) - drive volume is 'Online' and shown as 'Health' but it is marked as 'Unknown' . [It does have the correct drive letter under properties from within the Failover Cluster Manager]
The 'repair' option on the failed drive is not active, is there anything else that we can do other than to wipe and start all over?
I'm not too worry about this since it is under Test/Development but my bigger concern is had this been in the production and this occurs, a full wipe and start over would then become extremely time consuming and not practical.
Thanks.
