I'm trying to set up a raid5 from three SCSI disks (I know that a serious raid5 should use five disks or more, but I have to make do with three at the moment). The configuration is as follows: drive ibma device /dev/da1s1e drive ibmb device /dev/da2s1e drive ibmc device /dev/da3s1e volume raid5 setupstate plex org raid5 512k sd length 0m drive ibma sd length 0m drive ibmb sd length 0m drive ibmc This works ok. Then I run vinum init to initialize the drives. Trying to create a filesystem on this construct results in the error message: newfs: wtfs: 65536 bytes at sector 71130688: Input/output error Is that trying to tell me that my calculation of the group size is incorrect? Does it have to do anything with the fact that the three disks have slightly different capacities? Vinum reports the disk sizes as 17500MB (da1) and 17359MB (da2, da3). The raid5 volume and plex have a size of 33GB. BTW creating a concatenated volume on the same disks works ok, newfs does not throw an error here. Any help is appreciated.
