Let's take a simple example setup: ccdconfig ccd0 128 CCDF_MIRROR /dev/da1e /dev/da2e The ccdconfig man page says that the ccd partition should be offset not to overlap the disklabel area. It is not clear however what should be offset: a) the component partitions (da1e, da2e in our example) from the beginning of their respective drives or b) the data partition I will create within ccd0c ? May be you will show your disklabel output? Thanks in advance for any input. And another question. Suppose one of the mirrored disks fails, I remove it, configure one disk ccd, work from it for a certain time, then bring another fresh HDD from the store. How am I supposed to return to mirrored configuration? -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/149@fidonet http://vas.tomsk.ru/ PGP key: finger vas@mpeks.tomsk.su To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
