I'm running FreeBSD 3.3-19991207-SNAP and I noticed this earlier today:
Dec 8 12:28:53 fred /kernel: nzmirror.p0.s1: fatal write I/O error
Dec 8 12:28:53 fred /kernel: vinum: nzmirror.p0.s1 is stale by force
Dec 8 12:28:53 fred /kernel: vinum: nzmirror.p0 is corrupt
Dec 8 12:29:53 fred /kernel: nzmirror.p0.s1: fatal write I/O error
then
Dec 8 12:31:23 fred /kernel: vinum: drive d2 is down
Dec 8 12:31:24 fred /kernel: vinum: Can't write config to /dev/da2s1e, error 5
Dec 8 12:31:24 fred /kernel: (da2:ncr0:0:4:0): SYNCHRONIZE CACHE. CDB: 35 0 0 0 0 0 0 0 0 0
Dec 8 12:31:24 fred /kernel: (da2:ncr0:0:4:0): NOT READY asc:4,0
Dec 8 12:31:24 fred /kernel: (da2:ncr0:0:4:0): Logical unit not ready, cause not reportable
Below are some other observations. Everything on the drives can be recovered
(its cvsup.nz.freebsd.org), but I'd rather not do that until I can source some
replacement drives.
thanks
