I was logged in as root but parted is not on my system. It's the last slackware.
root@cthulhu:/sbin# whereis parted
parted:

root@cthulhu:/sbin# cat $PATH
cat: /usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/usr/games:/opt/www/htdig/bin:/usr/lib/java/bin:/usr/lib/java/jre/bin:/opt/kde/bin:/usr/lib/qt/bin:/usr/share/texmf/bin: No such file or directory

Is this not normal?

Well, you're in a Red Hat specific forum here.

Redhat? I didn't notice that. (just did a search for my problem on all the forums)
Anyway, It works ok now. I first partitioned the hdb drive yesterday morning with cfdisk and it appears that there was still a partition (swap space from previous installation) on the disk. So when doing a mkfs, he made a filesystem on the whole 400MB that the partion was.
I removed thus again all partitions with fdisk and after a new mkfs, it was ok.
bye.

Hey,

I am going to do more or less the same.

I have no more space at / , so I will reformat a ntfs partition, making it reiserfs, and then transfering all my /opt to this new
partition (it is now under /, and it is using almost all off the space).

But I have still some doubts, because of course I am affraid of the possibility of destroing my data...

First:

Should I use

cp -a /opt /new_partition

or

mv /opt /new_partition

?

Will they, or wich one,m preserve my permitions and etc?

Then I just

1- go to single user, format and mount the new one,

2-change my fstab to point /opt to the new partition,

3- rename the old one,

4- reboot,

5- if everything is ok, delete the old one, if not, use the fstab .bak , rename again the old /opt and came here
at forum again asking for help?


BTW, this is what I have now on my Slack 10:

I hope to transfer /opt from / in hda3 (primary) to the /new in hda6

thanks and bye

cp -a, but not the way you've planned to. You would get the directory /new_partition/opt, which is not what you want when you plan to mount the new partition on /opt. You want "cp -a /opt/* /new_partition", so only the contents of /opt are copied.

I have a question along these same lines....(maybe).
Let's say I have created 3 x 5 GB partitions on a 20 GB disk. I know I have 5 GB left, but what is the best way to see how much unallocated disk space is left? Thanks.

i think you could try"

$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/md0 8.0G 6.5G 1.1G 86% /
/dev/hda1 244M 84M 148M 37% /boot
none 124M 0 124M 0% /dev/shm
jaws:/home/jhibbets/ogg
9.7G 8.7G 452M 96% /mnt/jaws

Not exactly what I meant. Let's say you forgot the size of the hard drive.
How would you determine unallocated disk space?

Various ways to do that. Look at the physical size of the drive as reported in the /var/log/dmesg file or by running parted /dev/hda print or fdisk -l /dev/hda or entering the partition tools to examine the disk.

Thanks Misc! So in the example below, I have roughly a 17 - 18 GB disk, correct?

# parted /dev/cciss/c0d0 print
Disk geometry for /dev/cciss/c0d0: 0.000-17359.921 megabytes
Disk label type: msdos
Minor Start End Type Filesystem Flags
1 0.016 51.796 primary ext3 boot
2 51.797 5868.984 primary ext3
3 5868.984 9869.296 primary ext3
4 9869.297 17359.921 extended lba
5 9869.312 11865.468 logical linux-swap
6 11865.484 16718.437 logical ext3
7 16718.453 17100.937 logical ext3
8 17100.953 17355.937 logical ext3

One other question. What is a good solid way to determine what disks are on the server.
For example; What if I forgot I have two other hard drives on this server, that are not being used.
What could I do to determine how many disks are physically plugged in? Thank you everyone for the help!

-gromo

As above, /var/log/dmesg

Thanks!
Do you have some example output from /var/log/dmesg, that you could share with us?
What do we want to look for, that tells us this is a disk?

I think you can see it somewhere in the dmesg like this:

Normally it detects all the harddrives that are on your system, even those that aren't mounted or don't have a linux partition.
