On XFS file system we can change mount options from inode32 to inode64 but not the other way .Following are possible options .
a) Use 64-bit database client to install on existing mount point .
b) Reformat filesystem to be <1TiB in size and mount only with inode32 with help of system admin or operating system vendor ,if there are no other applications or clients installed on same mount point .
c) Create a new mount point with inode32 for 32-bit applicatioins/client
d) Install database client on other local filesystems such as ext4 .
Note :- Suggested to reformat file system with less than 1TB is due to known issue as mentioned in XFS documentation

Errors on XFS file system for large disks mounted with 64-bit inode (inode64) option
The use of the XFS file system, the default local filesystem on Oracle Linux/RHEL 7, for larger disks (greater than around 1TB) with the inode64 mount option may result in errors when using EBS such as:

Preparing to launch Oracle Universal Installer from..
Please wait …Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
This is due to the use of 32-bit executables in EBS which can result in the accessing of inode numbers on the file system that are greater than the 2^32 limit of the 32-bit userspace. It is recommended to use the 32-bit inode option (the default for XFS) or other local filesystems such as ext4 if this problem is encountered.
