[zfs-discuss] Adding to zpool: would failure of one device destroy all data?
I didn''t find any clear answer in the documentation, so here it goes: I''ve got a 4-device RAIDZ array in a pool. I then add another RAIDZ array to the pool. If one of the arrays fails, would all the data on the array be lost, or would it be like disc spanning, and only the data on the failed array be lost? Thanks in advance.

Your data will be striped across both vdevs after you add the 2nd vdev. In any case, failure of one stripe device will result in the loss of the entire pool. I''m not sure, however, if there is anyway vm recover any data from surviving vdevs. On 1/2/08, Austin <ShyGuy91284 at atwelm.com> wrote:> I didn''t find any clear answer in the documentation, so here it goes: > > I''ve got a 4-device RAIDZ array in a pool.
