For future reference, it is a lot easier to associate partitions with a single top-level directory than with multiple ones, as you have chosen to to. For example, if I assign a partition to /home, I can just mount it there in fstab, without needing to use the symlink indirection you use: /dev/hda4 /home ext2 defaults 0 2 >Bu I am facing one problem. > >When I boot my system logger does not see the /var/log which has been moved >to the new location . > >The system just hangs . At what point does it "just" hang? What is the last message on screen? And how long do you wait ... are you sure it is a true hang and not a problem that times out after, say, 3 minutes? >When I boot in single mode by passing an argument to my kernel that does >show in the dmesg in the new location . > >In addtion when I run a command like 'clear ' it shows that it could not >find the library to run it . Where does your system have libncurses.so.5 (the "missing" library)? On my systems,it is always in /lib, a hard place to lose. >I have mounted hda5 & hda6 in my fstab . > >I did create soft link for my new var , new tmp & new usr to the the /var , >/tmp , /usr as ffs :- > >ln -s /mnt/hda5/var /var >ln -s /mnt/hda5/tmp /tmp > >ln -s /mnt/hda6/usr /usr This should all work fine, assuming the symlinks are created immediately after the partitiions are mounted during the init process. >I moved the old files using the ff commands:- > >cd source directory > >cp -ax * /mnt/usr5/var > >or > >cd /src/dir ; tar cf - . | (cd /dest/dir && tar xvf - ) > > > > >But still it does not work . > >Please find attached the dmesg & library error and fstab. I assume the dmesg example is from the single-user boot, not the one that "just hangs". So it doesn't tell us what is up with the hang. Next time, please also include the output of ... ls -l / df ... and if you are reporting the results of two different boot/init sequences (single user and multiuser) please be VERY VERY clear about which attempt each result goes with. >Please advice. > >Thank you for your help in advance. > >bj Hi Ray ! Thank you for the prompt reply. 80 % of the solution worked . 1. I did mount hda5 & hda6 as below . 2. After I keyed in the symbolic links as below my commands could find the lib . 3 But the sym link to /var did n't work & once I reboot , the system created a /var by itself .The system created /var is mostly empty . If I delete that auto created /var , and reboot , it creates the /var again . The contents I have listed below . 4. yes , the system stopped for 5 minutes looking to start the system logger . After it could not find it , the boot process move forward and the normal login prompt did come( not single user but multi user login prompt ) . So you were right , the system didn't hang but just stopped for 5 minutes trying to start the system logger . . I did mount hda5 & hda6 in the fstab . Cat /etc/fstab gives the ff LABEL=/ / ext3 defaults 1 1 none /dev/pts devpts gid=5,mode=620 0 0 none /proc proc defaults 0 0 /dev/hda5 /mnt/hda5 ext3 defaults 1 2 /dev/hda6 /mnt/hda6 ext3 defaults 1 3 none /dev/shm tmpfs defaults 0 0 /dev/hda3 swap swap defaults 0 0 /dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0 /dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0 The symbolic link also worked . After I keyed in the ff :- cd / ln -s /mnt/hda5/var ln -s /mnt/hda5/tmp ln -s /mnt/hda6/usr ln -s /mnt/hda6/home Once I cd / and give the four link (ln ) commands three work . The result running file command on the links :- usr: symbolic link to /mnt/hda6/usr tmp: symbolic link to /mnt/hda5/tmp But the link to var didn't . It gives no error message. But when I type reboot , it shows that it could not find a file shutdown.pid under /var . Once I reboot , it gives quite few error messages that shows that it could not still find /var. It does stop around 5 minutes trying to start the system logger & after 5 minutes , it keep boots successfully. After I log in I notice a /var directory has been created . This /var has been created auto , as I didn't create it . The system is auto creating this directory & removing the sym link ,and so it does not find the other needed files in /var. Why do you think this is happening ? In addition I would also like to have the command to mount a partition read only such as /usr on a readonly partition. Cheers, bj When I do ls -lR on the auto created /var , it gives out the ff contents :- var: total 4 drwxr-xr-x 3 root root 4096 Feb 27 09:28 lib var/lib: total 8 -rw------- 1 root root 512 Feb 27 09:28 random-seed drwxr-xr-x 2 root root 4096 Feb 27 09:22 rpm var/lib/rpm: total 308 -rw-r--r-- 1 root root 8192 Feb 27 09:22 __db.001 -rw-r--r-- 1 root root 1310720 Feb 27 09:22 __db.002 -rw-r--r-- 1 root root 360448 Feb 27 09:22 __db.003 -rw-r--r-- 1 root root 12288 Feb 27 09:22 Name -rw-r--r-- 1 root root 12288 Feb 27 09:22 Packages - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
