My question is: Given the assertion that it's not safe to keep lock
files on an NFS partition, what mechanism do/would/should people use to
enable two applications running on seperate physical machines to use the
same lock file directory?
I don't have experience with NFS, but the issue has cropped up numerous times on this e-mail list, and the general advice is "don't use Lucene on NFS drives, period", and that is why we provided that same advice in LIA. However, I'm admittedly unknowledgeable in the reason the problem exists.
(this question is based on the understanding that unless the applications
are sharing the same lock directory, and index may be corrupted by
concurrent modifications, correct?)
Right - concurrent writes to the index could cause trouble.
