NAME

6       nbdkit-full-plugin - nbdkit plugin which is always full
7

SYNOPSIS

9        nbdkit full [size=]SIZE
10

DESCRIPTION

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.
18
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 \
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.
