Re: add and copy a partition
Just wonder, the reboot is really annoying. Are they going to fix it in the new kernel or there is a way (even complicate) around ?

first: using tar is POSIX compliant, thus you can use tar method on
any POSIX(applications) compliant machine.
second: this is the Unix way.

Sure: serialize (or pickle, or marshal) simply means to get a flat representation of a data structure. For example, you could say computer programs are seralized representations of the parse trees. I think the term pointer-isomorphism should be obvious: a non-formal definition wouild be to say that there is a mapping between the addresses such that one structure goes into the other.

Re: add and copy a partition
Hi I have ran out of space on my /home/USER partition and I would like to erase one of my windows partions and to make it ext2 and to copy the /home partition on it (exactly as it is - without the need to make a new user and install everything from scratch). Is it possible ? Can someone show me how to do it ? It is possible. This or a very similar problem was discussed many times on the list. You can probably find an exact recipe in the list archive. My favorite solution is to read www.linux.org.il/LDP/HOWTO/mini/Hard-Disk-Upgra de.html.

Can someone show me how to do it ? assuming you can red HOWTOs and such, here's the skinny: - fdisk to change the partition type. if changing the size too, you must reboot if another partition is mounted from that drive. as long as even ONE partition is mounted from that same disk, the kernel won't re-read the partition table. - mke2fs on it - mount it on /mnt/newhome or somewhere. - stop mail daemons or anything running. infact maybe do all this at runlevel 1 (init 1) - copy the stuff over, I use "cp -a /home/* /mnt/newhome" - switch around: mv /home /homeold (umount and remount if a seperate partition) mkdir /home umount /mnt/newhome -- change/add the entry in fstab mount /home et voila. have fun, if you have abslutly any more questions, please don't hesitate not to call me. -- Ira Abramov ; Penguinophile ; www.linux.org.il And 1.1.81 is officially BugFree(tm), so if you receive any bug-reports on it, you know they are just evil lies."
