Subject Can solrcloud be running on a read-only filesystem?
Date Fri, 02 Jun 2017 10:56:19 GMT
Hi All:

We have a normal build/stage -> prod settings for our production pipeline.
And we would build solr index in the build environment and then the index
is copied to the prod environment.

The solrcloud in prod seems working fine when the file system backing it is
writable. However, we see many errors when the file system is readonly.
Many exceptions are thrown regarding the tlog file cannot be open for write
when the solr nodes are restarted with the new data; some of the nodes
eventually are stuck in the recovering phase and never able to go back
online in the cloud.

Just wondering is anyone has any experience on Solrcloud running in
readonly file system? Is it possible at all?

Regards,
Wudong
