Re: Troubles with moving /var
Ciao Alberto Bigazzi, I actually did it by hand, by tar-ing /var, copying it under /home and untaring it there. Then deleting /var and symlinking /home/var to /var. But I guess this is something VERY BAD as I ended up with lots of problems with PERMISSIONS. Now normal users CANNOT write into directories under /var, like /var/log or /var/lock, so I get lots of troubles of any kind... I have done the same things, with the same errors... :-) I think that the problems are all that daemons that don't want to recognize the changes. shutdown now should fix all (or stop restart all daemons).

Troubles with moving /var
The / partition on my home PC is fairly small and sometimes gets filled up because ov /var, so I've decided to migrate /var somewhere else. I have /usr and /home as separate partitions and would like to leave /usr alone, thus putting /var under /home, which is quite large and nearly unused (it's just a home PC, and use it to connect to the 'real' one at work). Q: Which is the correct way to do this? === I actually did it by hand, by tar-ing /var, copying it under /home and untaring it there. Then deleting /var and symlinking /home/var to /var.

Now normal users CANNOT write into directories under /var, like /var/log or /var/lock, so I get lots of troubles of any kind... sounds like you forgot the -p switch to tar, which preserves the permissions, without it everything gets set according to your (probably root's) umask, if you have already nuked the real /var then your in for a bunch of chmoding i suppose.. I am not sure the best way to find out what the permissions are supposed to be other then have someone send you a recursive ls -l of their /var hierarchy. I am not aware of any quick way to restore the permissions to the proper values other then manually at this point, perhaps someone else has some ideas? just a couple i can tell you now, /var/lock is mode 1777, /var/log is mode 755 (users should not be able to write there), /var/spool/mail is mode 2775 those are the most important `special' directories i can think of right now, but there are several daemons with special directories under /var that have different owners/modes to allow them to run non-root. always mv the old directory out of the way and test your change before rm -rfing it ! :-) -- Ethan Benson To obtain my PGP key: http://www.alaska.net/~erbenson/pgp/
Re: Troubles with moving /var
i moved /var /home /usr with the command cp -a which preserves everything, i did it on 2 main servers and have nbot had a single problem so i bet its a safe way of doing it(the servers have been online since april) cp -a doesn't work on more obscure platforms like irix..there is a tar command..that acts like cp -a i saw it posted in a magazine(Maximum Linux) but i forgot what it was, if its linux its safe to use cp -a nate On Mon, 20 Dec 1999, Alberto Bigazzi wrote: albbig albbig The / partition on my home PC is fairly small and sometimes gets filled albbig up because ov /var, so I've decided to migrate /var somewhere else. albbig albbig I have /usr and /home as separate partitions and would like to leave /usr albbig alone, thus putting /var under /home, which is quite large and nearly albbig unused (it's just a home PC, and use it to connect to the 'real' one at albbig work). albbig albbig Q: Which is the correct way to do this? albbig === albbig albbig I actually did it by hand, by tar-ing /var, copying it under /home and albbig untaring it there.
