[OpenAFS] About cache persistence over reboot

[nicolas prochazka]

Hello,
Can someone explain me if afs cache client persists after restart/reboot of afsd

Server : Linux Gentoo openafs 1.6.2
Client : Linux Gentoo openafs last git 1.6.3

- When I start my afsd cache, and copy some files, the cache grows up.
- If I restart afsd ( /etc/init.d/openafs-client restart ) , my cache
is recreate and only contains the primary directories.

Is it a normal behavior ? the cache only persist during afsd running ?
not after restart or reboot

Best Regards,
Nicolas Prochazka.
