[jira] [Commented] (TS-1161) insafe raw device in storage.config

["Leif Hedstrom (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-1161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13235647#comment-13235647 ] 

Leif Hedstrom commented on TS-1161:
-----------------------------------

Yeah, don't use e.g. /dev/sda. Use /dev/disk/by-uuid/...   or /dev/disk/by-path/...  or some such, and make sure you get it right. :)

I guess we could try to detect if a disk is in use, I don't know if there are any portable and reliable ways to detect that (but, I haven't looked). It's not as easy as looking via "mount" etc., you have to take into account various other disk managers, such as LLVM, or even just the software raid layers.

> if you system is on /dev/sda and you put /dev/sda into storage.config, TS will destroy the data on /dev/sda without any hesitate.
> this is proved to be true, please do not try, trust me.
