If centralization of storage is your goal by choosing NFS, iSCSI works
reasonably well with SOLR indexes, although good local-storage will
always be the overall winner.
I noticed a near 5% degredation in overall search performance (casual
testing, nothing scientific) when moving a 40-50GB indexes to iSCSI
(10GBe network) from a 4x7200rpm RAID 10 local SATA disk setup.

Solr 4.2 does have field compression which makes smaller indexes. That will
reduce the amount of network traffic. That probably does not help much, because
I think the latency of NFS is what causes problems.

Hello Walter,
Thanks for the response. That has been my experience in the past as well.
But I was wondering if there new are things in Solr 4 and NFS 4.1 that make
the storing of indexes on a NFS mount feasible.
Thanks,
Saqib

Greetings,
Are there any issues with storing Solr Indexes on a NFS share? Also any
recommendations for using NFS for Solr indexes?
I recommend that you do not put Solr indexes on NFS.
It can be very slow, I measured indexing as 100X slower on NFS a few years
ago.
It is not safe to share Solr index files between two Solr servers, so
there is no benefit to NFS.
