Fixed In Version: ovirt 3.5 rc1
Doc Type: Bug Fix
Doc Text:
Previously, creating or editing an NFS storage domain's mount path so that the server's name ends in a digit (for example: myhost1:/path/to/data) was not allowed, meaning that legal host names could not be used as storage servers providing NFS storage to Red Hat Enterprise Virtualization. This limitation has now been removed so that hosts with names ending in digits can now be used as NFS servers.

Description Marcus West 2014-07-21 03:24:04 UTC
## Description of problem:

In RHEV, admin UI rejects FQDNs ending in a digit when creating NFS storage domains

## Version-Release number of selected component (if applicable):

3.4, customer also reports this happening in 3.2

## How reproducible:


## Steps to Reproduce:
1. Create an NFS Data Center
2. On storage, create an appropriate NFS share
3. Via DNS create a domain that ends in a digit (ie: foo.example.f7)  Or, just update /etc/hosts so that storage resolves to this name.
4. Try to create a storage domain with foo.example.f7:/<export>

## Actual results:

Attempt to create SD fails ("Error while executing action: Mount path is illegal, please use [IP:/path or FQDN:/path] convention.")

## Expected results:

Create SD as expected, with FQDN ending in a digit

## Additional info:

The workaround is to use the IP address, or short host name (assuming domain is in resolv.conf search path). 

While this is an unusual domain name, It is to my knowledge valid [1], and I can't see any logical reason why it should be excluded.

Comment 1 Allon Mureinik 2014-08-03 09:41:18 UTC
Technical insight:

This error doesn't come from the fortend (see test in http://gerrit.ovirt.org/#/c/30964/ that proves this point).

The failing validation comes from the backend in NfsMountPointConstraint.

Marcus, is this bug intentionally private?

Comment 4 Elad 2014-08-14 10:44:56 UTC
Eyal, this bug is targeted for 3.5 downstream. 
Since there is no such build, Can we verify it on ovirt-3.5 RC1?

Comment 5 Elad 2014-08-14 10:46:34 UTC
Also, please add 'fixed in version'

Comment 6 Elad 2014-08-14 12:38:17 UTC
Verified based on https://bugzilla.redhat.com/show_bug.cgi?id=1126342#c1

 Ori 2014-08-13 09:56:16 EDT

verified on rc1
steps taken:
1.edit /etc/hosts file with FQDN that ends in a digit to an NFS domain ip
2.connect to that domain
