 ===== How-Tos =====
 ==== Clone a pool without losing snapshots ====
@@ Line 5: / Line 11: @@
 You have just to create a snapshot and send it to the new pool. All the previous snapshots will be sent preserving dates and names.
 <code>zfs send -R MY_OLD_POOL@MY_LATEST_SNAPSHOT | zfs receive -F MY_NEW_POOL</code>
+==== Compile latest release for Debian ====
+<code>
+# apt install --yes debootstrap gdisk dpkg-dev linux-headers-$(uname -r) \
+  git-buildpackage build-essential dkms libaio-dev \

+==== Expand zpool to size ====
+This command works with the volume, not the pool. You will need to execute it for every volume if you pool has more than one.
+<code>sudo zpool online -e zpool-docker nvme-Amazon_Elastic_Block_Store_volxxxxxxxxx</code>
