Description Curtis Doty 2009-02-01 22:42:16 EST
Running this:

  lvreduce --test --resizefs -L4G foo/bar

Will run both of these:

  fsadm check /dev/foo/bar
  fsadm resize /dev/foo/bar 4194304

Note that fsadm has an option for --dry-run but it isn't used!
Comment 1 Alasdair Kergon 2009-02-02 07:43:21 EST
Thanks for spotting and reporting this!

Normally --test is safe because it prevents the program from issuing any writes.
We need to add some new protection for fork/exec.
Comment 2 Alasdair Kergon 2009-02-02 09:27:50 EST
Default behaviour for exec_cmd() in test mode should be to print the command but not actually execute it.

Then some exceptions can be made to that, such as if the command is fsadm, add '--dry-run', and MODPROBE_CMD is probably OK too.  (The "fsadm" hard-coding should be removed too and replaced with a similar FSADM_CMD.)
Comment 3 Zdenek Kabelac 2009-02-25 07:39:24 EST
support for  --dry-run added by commit:
