Beside the ability to recover from disk failures, other features of SnapRAIDare: All your data is hashed to ensure data integrity and to avoid silent corruption.Has anyone played with Neth in this environment? That got Neth running on a single-disk pool.

This blog post has the instructions I ov2740 to GPT partition two more virtual disks, both larger than the first. For some reason, the instructions I followed do not create the pool with the autoexpand property turned on. Once the resilver completes, I expect I should be able to zpool detach the first virtual disk, and the pool will then become a two-way mirror. It should also automatically expand to the size of the new virtual disks.

Edit: Well, that mostly worked. Probably should have done that. Very little if any of this is original to me; my sources are linked above. In the CentOS installer, set up custom partitioning.

Brandon Schneider. Mounting a dataset or directory via iocage fstab will be what's called a nullfs mount. That will let you access the data, but a jailed dataset is not the same thing. To post to this group, send email to ioc Ahh, very cool. So you can actually perform other ZFS operations on your dataset from within the jail. As in, make snapshots, additional sub-datasets, etc? Whereas, if I understand rightly, a nullfs-mounted dataset will be controlled completely from outside the jail.

Are there performance benefits or drawbacks between the jailed dataset approach and the nullfs approach? And I haven't benchmarked either very heavily but nullfs performs very well. I appreciate this example, and it works fine when creating an additional dataset on the same ZFS root as the jail, but is there a way to make it use a dataset from a different root?Disk mirroring is a good choice for applications that require high performance and high availability, such as transactional applications, email and operating systems.
