zfs destroy pool-x@snap1

     Example 12 Remotely Replicating ZFS Data
       The following commands send a full stream and then an
       incremental stream to a remote machine, restoring them
       into poolB/received/fs@a and poolB/received/fs@b, respectively.
       poolB must contain the file system poolB/received, and must
       not initially contain poolB/received/fs.

       # zfs send pool/fs@a | \
         ssh host zfs receive poolB/received/fs@a
       # zfs send -i a pool/fs@b | \
         ssh host zfs receive poolB/received/fs

     Example 13 Using the zfs receive -d Option
       The following command sends a full stream of poolA/fsA/fsB@snap
       to a remote machine, receiving it into poolB/received/fsA/fsB@snap.
       The fsA/fsB@snap portion of the received snapshot's name is
       determined from the name of the sent snapshot.
       poolB must contain the file system poolB/received.
       If poolB/received/fsA does not exist, it is
       created as an empty file system.

       # zfs send poolA/fsA/fsB@snap | \
         ssh host zfs receive -d poolB/received

Agrandissement du disque ZFS de web4a

Agrandir le disque depuis https://admin.komodo.ch

Il est probable que l’agrandissement depuis l’admin komodo ne se réalise pas directement. En règle général il y a un intervenant chez eux qui va appliquer la configuration demandé et le résultat est visible le lendemain. Si le résultat ne se fait pas tout de suite, il est recommandé d’écrire au support pour expliquer ce qui a été fait et ce qui est attendu.
