10
12 "nbdkit-full-plugin" is a plugin for nbdkit(1). Reads from this
13 virtual disk return zeroes. All writes and similar operations like
14 zero and trim fail with "ENOSPC" (No space left on device) error.
15
16 In other words this behaves like a sparse (thin-provisioned) virtual
17 disk which has run out of space on the host.

19 Equivalent nbdkit-error-filter command
20 Although this is a standalone plugin, it is equivalent to using
21 nbdkit-error-filter(1):
22
23 nbdkit --filter=error null size=SIZE \
24 error-pwrite=ENOSPC error-pwrite-rate=100% \
25 error-trim=ENOSPC error-trim-rate=100% \
26 error-zero=ENOSPC error-zero-rate=100%
27
28 nbdkit-error-filter can be more flexible because you can place it on
29 top of other plugins and you can control when to inject errors.
30
32 size=SIZE
33 Specify the virtual size of the disk image.
34
35 This parameter is required.
