[OpenAFS] Windows Integration with Kerberos

2008-04-21 Thread Prasun Gupta
We would like to use windows client to authenticate with an Kerberos Server (KDC), get a windows user's roaming profile and then map the user's afs homespace on the machine. From What I have read the user Kerberos credentials have to be mapped to a windows user account, defined locally or in

Is there substantial reason to believe that this has been addressed between 1.4.6 and 1.4.7pre3? The boxes that (I would guess) experience this are beefy/fast boxes. Our hosts in question are production machines, not ones we can perform OpenAFS testing on unless there is a clear case for the

[OpenAFS] zfs File system

On solaris the recommended filesystem of use for building afs filesystem is ufs without logging turned on. This is really a very primitive file system, and it loses a lot of the new features in the filesystems. Has anybody used zfs successfully and in what configuration ? a) striped zfs

At my last job, we had switched to using ZFS exclusively for our AFS servers, and had great luck with it. Look back in the archives of this list for discussion of it, and check out one of my ex-coworker's presentations from the 2007 AFS workshop on just that subject:

We currently run with a cache set at boot time at 75% of the partition size, and this has reduced the frequency of the problem to close enough to zero for us. At previous higher values (85% ??) we still saw this on an infrequent but regular basis (across 100s of hosts). Every one of our
