I get Operation not permitted for root user on one server but not on the other "identical" server.
Running on Amazon Linux 1.
Server 1:

Mounted as rw per mount cmd on both servers. Both servers have identical /etc/fstab.
Setup on both servers is identical:
lrwxrwxrwx 1 root root 14 May 21 2018 s3mnt -> /storage/s3mnt
drwxr-xr-x 7 brutus brutus 4096 May 21 2018 storage
# mount
s3fs on /storage/s3mnt type fuse.s3fs (rw,relatime,user_id=0,group_id=0,allow_other)
When changing permissions on the mountpoint I get the expected changing ownership of Input/output error. So it's not that. Wish it was :(
What else can I check to find out why I am running into the above issues on one server but not the other?
