If you extract one of the disks, the logical volume associated to it is invalidated. So, you insert a replacement disk, and the card refuses to recognize the volume.

Can you do this by marking it as 'good' via mfiutil and then using mfiutil to create a volume? -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
