Hello,
I have read the referenced thread with great interest,
and I have a related question.
If we replace NAS with SAN (SAN is basically a remote
block device).
If a single server mounts the SAN partition, and a single
derby server is run on this server, I guess we shouldn't
encounter any trouble, should we ?
Regards,
M. Maison

Hi,
I work in a french company which provides secure online file
management services (SaaS solutions).
In one of our applications (backup software), in case of a large
file, we cut it into blocks and we use a Derby db in order to
maintain the block indexes. These Derby dbs (version 10.5.1.1) are
stored on a NAS (cluster Isilon NL series) shared between webservers.
The derby db is directly acceded on NAS and it is thread safe.
Everyday, we are observing many Derby db corruptions (Unknown page
format at page Page(524,Container(0, 1024))) and these dbs are no
longer usable.
I join the derby log file corresponding to the last night on 1
webserver.
Thanks in advance for your help.
Best regards,
