The actual meta-data of snapshots are negligible. As a copy-on-write file system, ZFS snapshots only require space for modified data; creating a snapshot does not immediately duplicate everything. If you have a snapshot of given size, and then add or modify files summing up to 100GB, the snapshot will "cost" you 100GB. It might even be a little bit smaller ...

A snapshot initially takes a very negligible amount of space. Its size grows later when existing data in the snapshotted dataset is updated or deleted. The maximum size of a snapshot is the size of the original dataset unless compression and/or deduplication is enabled in which case you might have a snapshot smaller or larger than its parent dataset.

With help from this question and its answers I was able to get this working (currently resilvering). To any ZFS developers reading this, the operation of replacing a disc should be made much easier/full (and fool) proof. After the initial setup and on a long enough time line the only operation every ZFS user will eventually have to do is replace a disc. ...

If I'm correct that you installed ZFS via dkms then it looks like you need to remove it via the same tool. dkms remove [module/module-version] [-k kernel/arch] [--all] Removes a module/version or module/version/kernel/arch combination from the tree. If the module is currently installed, it first uninstalls it and if ...
