Mapping SAN to cluster nodes
I have mapped a block of space from SAN to 3 cluster nodes (2012r2)as below:
- 2 ports from each node have been mapped to the same share on SAN for redundancy.
- MPIO has been configured on all nodes
- SAN share has been successfully added to all nodes .
Question:
Should I see the same contants of that SAN share on all nodes, currently I created some files from 1 node, but I could not see those files in that share from other nodes?
Any idea why?
Oh god, you've not have you? You've just caused immediate, irretrievable data loss sorry.
NTFS isn't a cluster-aware file system, you need something to act as a lock manager too.
MS Cluster Services can do some of this for you but they won't be active/active as I suspect you want - for that you might needs something like Symantec Storage Foundation which uses it's own file system for this.
Either way that 'share' is dead, you'll need to wipe it.
