Been playing with 5.1-beta (Jan. 21 build) in the interests of seeing
what I need to get together to set up my next system. I was hoping to
do it with three drives, booting from a softraid RAID 5 volume.
When installed and rebooted, all works OK. What I've been running into
are panics when trying to run the softraid volume in degraded mode,
i.e. if I disconnect a drive and start the system.
I've seen similar issues with a RAID 5 volume mounted on just /home
instead of on /. RAID 1 appears to work fine, though.
Here's one example. Though the panic traces vary, they're all very easy
to reproduce--just set up a three-drive RAID 5 array, then bring up the
system with one drive missing.
