</question>
<answer>
<para>This could happen because the pool is 100% full.
ZFS requires space on the disk in order to write
transaction metadata. In order to restore the pool
to a usable state, truncate a file you want to
delete.</para>
<screen>&prompt.user; <userinput>truncate -s 0 <replaceable>unimportant-file</replaceable></userinput></screen>
<para>File truncation works because a new transaction is
not started, new spare blocks are created instead.</para>
<note>
<para>On systems with additional ZFS dataset tuning,
such as deduplication, the space may not be immediately
available</para>
