+- Exec into the iSCSI node pod for the node where the volume is being attached.
+- Find the path where the volume is mounted, this should be in the error, and the disk name
+- umount <path>
+- resize2fs /dev/<disk name>
+- Receive the error that the filesystem isn't clean, press y to optimize
+- fsck -f /dev/<disk name>
+- Ensure the above comes back clean
+- resize2fs /dev/sdb
+- Restart pod that is mounting the disk
