I've been playing around with zfs for a bit, and ran into a problem where i corrupted an entire drive (on purpose) by way of dd if=/dev/urandom of=/dev/ad12 .. as expected, the zpool noticed: su-2.05b# zpool status pool: array1 state: ONLINE status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Replace the device using 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-4J scrub: resilver completed with 0 errors on Mon Jul 23 23:05:53 2007 config: NAME STATE READ WRITE CKSUM array1 ONLINE 0 0 0 raidz1 ONLINE 0 0 0 ad10 ONLINE 0 0 0 ad12 UNAVAIL 0 0 0 corrupted data ad14 ONLINE 0 0 0 ad16 ONLINE 0 0 0 raidz1 ONLINE 0 0 0 ad18 ONLINE 0 0 0 ad20 ONLINE 0 0 0 ad22 ONLINE 0 0 0 ad24 ONLINE 0 0 0 errors: No known data errors now i want to resilver that disk, but the problem is this: su-2.05b# zpool replace -f array1 ad12 invalid vdev specification the following errors must be manually repaired: ad12 is in use (r1w1e1) but nothing is using that disk as far as i can tell! has anyone successfully done this? would it be better to use slices instead of whole disks for zfs on freebsd? i want to get some experience with this so that i know what not to do when a disk breaks for real :) -- Best regards, Sverre S mailto:ss.alert@online.no
