Hello Florin,
As the filesystem servers do not exist anymore as you deleted it previously,
the client could not reach them to complete the unmount process.
Try unmounting them using '-f' flag, ie: 'umount -f <filesystem path>'
You should also reach out to AWS support and check that with them.

We've created a few Lustre FS endpoints in AWS. They were mounted on a
system. The Lustre endpoints got terminated soon after that, and others
were created instead.
Now the old Lustre filesystems appear to be mounted on that node, and
there's automation trying to unmount them, resulting in a very large
number of umount processes just hanging. In dmesg I see this message
repeated many, many times:
Lustre: 919:0:(client.c:2116:ptlrpc_expire_one_request()) @@@ Request
sent has failed due to network error:
What is the recommended procedure to unmount those FSs? Just running
umount manually also hangs indefinitely. I would prefer to not reboot
that node.
