hy ,
if i understand you right and you want to move the partition just one time
, delete all records from the vldb which point to the server , you want to
make free with vos delentry . migrate the harddrive to the other server
and restart the fs process . now make a vos syncserv and syncvldb and all
your volumes are now on the new Server .
but don't forget , for this task you have a downtime of your system ...

Re: [OpenAFS] Switch containers between two fileservers
Sorry my unclean description. I don't want to move the volumes. I want
to change the physical disks between two servers. Server A has 400GB
data container and should stay serve as an AFS server. Server B has
800GB data container and currently is also an AFS fileserver. However,
we need to switch the RAID containers (by changing harddisks) between
those 2 servers and use server B for different purpose.
So the question is:
Can I move all volumes from server A to server B and then take the B's
drives and put them into server A?
Thank you.
