I run rebuildparity if checkparity finds any errors after unclean shutdowns. > The problem is that I can't find anything in the vinum docs about this > command other than it's purpose.

When reviving a disk the data on that disk is calculated from the data and the parity on the other disks. I think rebuildparity only reads data and writes the parity calculated from that but for all disks. > When I start a degraded disk it starts to revive -- which led me to believe > that vinum was also recalculating the parity.

I'm pretty sure, that it isn't. -- Christian Laursen _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
