Hello,
Afs Cache must persist after reboot, but it's not the case in my
configuration, i do not know why :
Can someone explain me ?
Server : Linux Gentoo openafs 1.6.5
Client : Linux Gentoo openafs 1.6.5
kernel module 1.6.5
1 - Boot, afs cache is filling with data ( ~ 260M , network bandwith
show me ~ 260M also ).
2 - shutdown
3 - boot, all data seems to be redownload from server ( network
bandwitch show me ~ 260 M)
cat /etc/openafs/cacheinfo
/afs:/var/cache/openafs:474276
afsd -afsdb -dynroot -verbose -debug
afsd client, debug msg :
