After working fine for two weeks now, all of a sudden my NSS pool on a
RAID 5 container in OES Linux SP2 disappeared. I went into ncpcon,
typed volumes and got only SYS and _ADMIN. I typed mount volumename
and it could not find my volume. I did an /etc/init.d/nss restart and
that didn't help matters. I rebooted the server and it all came back.
Firstly, I want to know why this happened, so I can try to make sure it
doesn't happen again. And if it does happen again, I want to be able
to fix it quickly without having to reboot the server. This is a
production web app server. Thanks.
