hard-link

This is what I would like to do. I have a symlink "/var" linking to "/tmpfs/var.1"

/var -> /tmpfs/var.1

I start a script called "cache_tmpfs" from /etc/rc.local on startup

this script will copy /var.backup/* contents to /tmpfs/var.1/

cp -dpRxf /var.backup/* /tmpfs/var.1/

now the problem is that kernel is opening messages log file in /var/log/messages, is it possible to remove the current /var symlink and recreate a new one (that will symlink to /var.backup insteed of /tmpfs/var.1) without issues as files once opened by system become hard links??

rm /var && ln -s /var.backup /var

Thanks...

Check if a file is real or a symbolic link

Is there a way to tell using C# if a file is real or a symbolic link? I've dug through the MSDN W32 docs (http://msdn.microsoft.com/en-us/library/aa364232(VS.85).aspx), and can't find anything for checking this. I'm using CreateSymbolicLink from here, and it's working fine. >>> More

RHEL5: Can't create sparse file bigger than 256GB in tmpfs

as seen on Server Fault - Search for 'Server Fault'
/var/log/lastlog gets written to when you log in. The size of this file is based off of the largest UID in the system. The larger the maximum UID, the larger this file is. Thankfully it's a sparse file so the size on disk is much smaller than the size ls reports (ls -s reports the size on disk). On… >>> More
MySQL & tmpfs : performance

as seen on Server Fault - Search for 'Server Fault'
I was wondering if, and how much, using tmpfs could improve MySQL performance and how it should be done ? My guess would be to do mount -t tmpfs -o size=256M /path/to/mysql/data/DatabaseName, and to use the database normally but maybe I'm wrong (I'm using MyISAM tables only). Will a hourly rsync… >>> More
