I don't think this is what was being asked for. My understanding is that they don't have a second array to move the volumes to, but would rather attach the existing array to the new server. I'll also venture a guess that the operating system on the new server supports the filesystem type(s) of the existing /vicepxx partitions and can run the namei fileserver. I would recommend reading the relevant portions of the AFS Admin Guide, in particular: http://www.openafs.org/pages/doc/AdminGuide/auagd008.htm#Header_160 for instructions on how to change a server's IP addresses (step 5 is where one might want to move disks from the old server to the new one), and http://www.openafs.org/pages/doc/AdminGuide/auagd008.htm#HDRWQ138 for information about the sysid file (which may be worth transferring to the new server). The topic has come up on this list before, so a look at the archives should help. One thread that seems relevant begins at https://lists.openafs.org/pipermail/openafs-info/2006-October/024192.html Maybe someone who has actually performed this kind of procedure (I haven't, yet) can comment further. Having a fresh backup of all the volumes involved should be helpful for one's peace of mind. (See José Angel's earlier question about backups, which I think is also answered in the archives.) _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
