[Voyage-linux] 'ro' changes in version .5 onwards

[Olivier Lacelle]

Well I'm not exactly sure about this but from what I can deduct from my voyage setup is this:
1- First I'm assuming that 'remountro' only locks the root mount "/".All the other mounts found when running the command df seem to stay writable.
2-Run the command lsof | more.It's a bit of a pain to go through but what you're looking for is a number followed by the letter 'u' or 'w' in the FD column, followed by 'REG' in the TYPE column with a path leading to a file NOT included in one of the mounts found in df in the NAME column. Here's an example:
COMMAND    PID    USER   FD      TYPE     DEVICE    SIZE       NODE NAMEminiserv. 4366    root    2w      REG        3,1     105       1019 /var/webmin/miniserv.error
In my case only webmin has such an entry, and it's the only program I've used that's given me problems.
Hope this helps.

How to check if any process is using the disk?
