NAME

       nbdkit-full-plugin - nbdkit plugin which is always full

SYNOPSIS

        nbdkit full [size=]SIZE

DESCRIPTION

       "nbdkit-full-plugin" is a plugin for nbdkit(1).  Reads from this virtual disk return
       zeroes.  All writes and similar operations like zero and trim fail with "ENOSPC"
       (No space left on device) error.

       In other words this behaves like a sparse (thin-provisioned) virtual disk which has run
       out of space on the host.

   Equivalent nbdkit-error-filter command
       Although this is a standalone plugin, it is equivalent to using nbdkit-error-filter(1):

        nbdkit --filter=error null SIZE \
                              error-pwrite=ENOSPC error-pwrite-rate=100% \
                              error-trim=ENOSPC error-trim-rate=100% \
                              error-zero=ENOSPC error-zero-rate=100%

       nbdkit-error-filter can be more flexible because you can place it on top of other plugins
       and you can control when to inject errors.

PARAMETERS

       [size=]SIZE
           Specify the virtual size of the disk image.

           This parameter is required.

           "size=" is a magic config key and may be omitted in most cases.  See "Magic
           parameters" in nbdkit(1).
