[one-users] Problem with datastores after 4.4 to 4.6 upgrade

[Matthew Richardson]

Hi,

Problem solved - I had accidentally run 'onehost sync' as root, rather
than oneadmin when I did the upgrade.  This left some of the files
inaccessible to the oneadmin user which caused problems.

In case anyone else hits this, to fix it I did:

On all the hosts:
chown -R oneadmin:oneadmin /var/tmp/one

On the server:
chown oneadmin:oneadmin /var/lib/one/remotes/.update

onehost sync --force host1,host2,...

Thanks,

Matthew
