The warning message you are receiving includes multiple comments, in other words, a summary of alerts\notices.
One of those notices is that you do not have enough spare disks in the system. in the cli, type, "Options raid.min_spare_count" which will show you the value of minimum spare disks for that system - this is configurable. If you have less spare disks in the system than what is configured in that option then this condition will trigger the alert you are seeing regarding minimum spare disks.
The other message you are seeing is that the volume shown is 71% full to capacity and 98% of inodes used(which is kind of like meta data on each file stored - and it obviously has a limit). When you increased the inode count on that volume how much more did you increase it by? (what is the current value?) And what is the new message you are receiving since you increase the inode count - you mentioned there was a new message.
