nbdkit-full-plugin(1) NBDKIT nbdkit-full-plugin(1) 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). FILES $plugindir/nbdkit-full-plugin.so The plugin. Use "nbdkit --dump-config" to find the location of $plugindir. VERSION "nbdkit-full-plugin" first appeared in nbdkit 1.10.
