Receiving alerts that FSDB is running out of space. I don't have high availability nodes, so seems like I'm unable to take the node offline.
1. How do I increase the size of this partition
2. Is there any way in the interface to see the current size of the partition, (to verify it has expanded)
You have to take the appliance down to expand the disk space. From there you can either add space to Hard Disk 2 (disk 1 is OS, and disk 3 is logging I believe), or add a new .vmdk. When you power up, the space will automatically be added. Job done.
