We managed to build the mirrors by using the suggestion above mirroring the slices separately. Unfortunetly, although the mirrors were created properly the filesystems are constantly suffering from inconsistencies and fsck actually appears to be segfaulting. We have decided not to pursue this any further for the moment, however we are prepared to allow access to the machine should anyone wish to try and sort out this incompatibility with gmirror and sparc.=20 Included below is a brief logfile of a reboot after fsck'ing all of the mirrored partitions. # reboot Waiting (max 60 seconds) for system process `vnlru' to stop...done Waiting (max 60 seconds) for system process `bufdaemon' to stop...done Waiting (max 60 seconds) for system process `syncer' to stop...
