I thought I did, but apparently not. I tried pulling the disk, replacing it with another disk having the same SCSI ID, and creating a label for it - ala the vinum web page. (this is after partitioning and changing the partition type with disklabel). When I start vinum, it shows the RAID5 plex as degraded, and the affected disk as down. So far, so good - the file system is slow, but fine. Next, I init the plex, using "init mmvolc.p0.s2". Ok, so how do I rebuild parity from here? I try starting the plex, and it comes up. No rebuilding parity, nothing. but when I try to mount the file system, it is trashed. (presumably because one of the disks is full of zeros!). I tried the step by step on the website, but it didn't work. Could someone give me some pointers on how to replace a faulty disk? Fortunately, I have backups of all the data - so I was able to fix these problems with newfs, and just restore - but that is a PITA, especially since I built the array to avoid having to do this just for a single disk failure.
