apacheds not starting anymore after server crash

[werner mueller <we...@mimacom.ch>]

hello

I'm a little desparate at the moment: we had a server crash. after 
rebooting the server i tried starting the apacheDS again but it 
terminates with an Input/output error in the logs (see below).

is there a way to repair the database or re-initialize it?
or is there another way?

we use apacheDS 1.5.4 with java 1.6 on Debian 4.0 (so far it was running 
for months with no issues)

any tipps would be great!

thanks a lot
regards

werner

FYI, the next version will have a ldif based schema, so it won't be 
possible to break it... We are currently working on that.

hello

thanks for the reply!

i was a little scared because the backups where all hot copies of the 
running server. but an older version did the job! the server came up 
running again!

it turned out the schema was broken in apacheds/data-default/schema/cn.db
that file could not even be copied anymore on the system itself (same 
input/output error.

can't wait for version 2.0 :-)


best regards

The only way is to remove all the .db/.lg files and to reinject all the 
data into the server. In other words, starting back from a backup :/

We are working on a DSR system (Disaster Recovery System) in order to be 
able to restore a base when it has crashed like that, it will be present 
in 2.0.

Sorry for the inconvenience ...
