[Linux-HA] Testing behaviour to disk faults

[vini.bill at gmail.com]

Well... You could try forcing the disk to be umounted after successful
service initialization ( as root; "umount -af" ). But I don't know if that's
what you want. You should expect some warnings and errors on
/var/log/messages and /var/log/localmessages.

Hope that helps.
