I'm not sure, may be solr should skip inaccessible directory.
Because it is standard rule to place service on separate filesystem.
On the other hand it is possible to place solr/home not on the top of
mounted fs.
Anyway it would be better if error message was more clearly.
2013/10/9 Erick Erickson erickerick...@gmail.com:
What do you think Solr should do in this case? If the
process doesn't have permission to the dir, it can't
write to it. You need to set the permissions, or the
authority of the process that Solr is running as
appropriately.
Best,
Erick

For example:
solr/home located on /var/lib/solr.
/var/lib/solr is another file system, it has lost+found directory, and
only root can read from this directory.
As result solr can't to star.
It is because discovering directory to which tomcat do not have rights.
Yours faithfully.
