Description of problem:
Alasdair Kergon 2014-08-13 18:01:41 EDT
The man page says:
WARNING: The cryptsetup-reencrypt program is not resistant to hardware or kernel failures during reencryption (you can lose you data in this case).
ALWAYS BE SURE YOU HAVE RELIABLE BACKUP BEFORE USING THIS TOOL.
THIS TOOL IS EXPERIMENTAL.
When you run the tool it says:
WARNING: this is experimental code, it can completely break your data.
I'm wondering if that runtime message should be changed to match the man page i.e. to tell you that you MUST take a backup because if the process is interrupted for any reason you will need to restore from it.
Version-Release number of selected component (if applicable):
Should we clone this for RHEL 7.1 as well?
It's not necessary. I would like to fix it in upstream as well. So it should go away with rebase in 7.1
Not so benign warning has been rephrased in https://gitlab.com/cryptsetup/cryptsetup/commit/1623ee71abb5bccb69ff691857d8f674b4f6dba4
The utility 'welcome' message has been dropped out. In the man mage there's no longer remark about the utility being experimental, but warning about power/hardware failure implications still apply.
Retested with cryptsetup-reencrypt-1.6.4-2.el6, cryptsetup-reencrypt no longer warns about being experimental, this message has also been removed from its man page.
Moving to VERIFIED.
