Hello, I'm having a play with gmirror, but I'm consistently running up against this problem: WARNING: Expected rawoffset 0, found 63 My chain of events is this: Start with a fresh disk, one slice covering the entire disk, no partitions yet: app1# disklabel -r da1s1 # /dev/da1s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 71119692 0 unused 0 0 # "raw" part, don't edit Set up a gmirror on it (this disk only at the moment, no other providers): app1# gmirror label -hv gms1 da1s1 Metadata value stored on da1s1. Done. In response to this command on console I see the following: GEOM_MIRROR: Device gms1 created (id=2385087336). GEOM_MIRROR: Device gms1: provider da1s1 detected. GEOM_MIRROR: Device gms1: provider da1s1 activated. GEOM_MIRROR: Device gms1: provider mirror/gms1 launched. WARNING: Expected rawoffset 0, found 63 app1# disklabel -r /dev/mirror/gms1 # /dev/mirror/gms1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 71119692 63 unused 0 0 # "raw" part, don't edit partition c: partition extends past end of unit disklabel: partition c doesn't start at 0! disklabel: partition c doesn't cover the whole unit! disklabel: An incorrect partition c may cause problems for standard system utilities da1s1 still shows: app1# disklabel -r da1s1 # /dev/da1s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 71119692 0 unused 0 0 # "raw" part, don't edit I feel I'm missing something blatantly obvious here. Is that offset of 63 something to do with metadata? Have I not left any space for metadata that I should have done? I was hoping that I'd be able to end up applying this gmirror command to an existing disk with live data on it, and then attach a free disk to achieve a complete mirror from an existing system? Are these warnings about partition c actually ignorable, or even normal? This system is 5.3-BETA5, built moments ago, and supped just before that. Appreciate any help. -- Chris
