[OpenAFS] RAID, AFS and tokens

[Petros Triantafyllidis]

Sorry for the long silence, but other commitments prevented my instant
response...

 As it came out, Craig Everhart was right who believed that the RAID
plugging was not the reason for unability of Windows clients to obtain
tokens.

Just to answer some of Shyh-Wei Luan's questions:

We are using Kerberos IV

Yes it is.

This is the only thing changed in our cell before the primary server's
restart. A second server (wich is also authentication server) was added
running RH 7.2 and OpenAFS. The first one was Solaris 2.6 and
Transarc's AFS. The new server listens both ports 88 and 750, according to
/etc/services.

This was my suspicion too. Now that I realized that the RAID was not the
reason, I am trying to find out what the possible cause could be. The main
server needed a "boot -r" to let the Win clients get authenticated.
Coincidence?

Thanks a lot,
Petros
