I'd really appreciate some help on this. I've submitted a github ticket, but I haven't got an answer. This is what I've done.

I installed a centos 7 server and followed the single node docker install on github

I ran both step1 and step2 scripts.

I login to the web ui

I created an object user named nfs_user.

I created a bucket named nfs_bucket. I added the nfs_user as the owner and added the nfs_group with r,w,exec permissions

I went to file and created users named nfs_user (10001) and nfs_group (10002) with the corresponding IDs

I created an export and used nfs_user under anonuser and root squash and nfs_group under anon group.

This is what happens on my client.

[root@localhost /]# showmount -e 10.44.236.152

Export list for 10.44.236.152:

/ns1/nfs_bucket *

[root@localhost /]# mount -t nfs -o vers=3,sec=sys,proto=tcp,async 10.44.236.152:/ns1/nfs_bucket /nfsshare/

[root@localhost /]# cd /nfsshare/

[root@localhost nfsshare]# ls -al

total 1

drwxrwxrwx. 3 10001 10002 96 Apr 26 16:28 .

[root@localhost nfsshare]# mkdir test_dir

[root@localhost nfsshare]# ls -al

[root@localhost test_dir]# touch file

touch: cannot touch ‘file’: Remote I/O error

[root@localhost test_dir]# echo 'help me' > file

-bash: file: Remote I/O error

[root@localhost test_dir]# cd ..

[root@localhost nfsshare]# echo 'why am I getting this IO error' > file

-bash: file: Remote I/O error

Any ideas here?
