Re: [OpenAFS] Question about RO/RW Volumes...
use the "-rw" option for "fs mkm" to force use of the RW volume. We do the same: all user volumes are mounted with -rw and have 2 RO copies one in the same partition to make the reclone fast and another one on another fileserver as a backup in case the 1st partition gets lost. We also have another tree where the RO-volumes are mounted to allow users to get back their files from yesterday. The automatic release of volumes theat have changed is done in a cron job on each fileserver machine during the night. Hartmut Lars Schimmer wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi!

Are you *really* sure, the mountpoints to these volumes (home, work, ftp) are correct? Try this: $ fs lsm /afs/path/to/home '/afs/path/to/home' is a mount point for volume '%home' The '%' is important. Another possible mistake is to have a difference between RO and RW of the volume containing '/afs/path/to' (=the volume containing the mountpoint to 'home'). Maybe you changed the mountpoint for 'home' but you didn't release the containing volume. HTH.
