mounting a reiserfs partition

[Commander]

hey guys,
i was running out of space in my main parition(/) so i decided to reize one of my fat32 partitions and create a new reiserfs parition for some of the bigger applications in the linux partition.  (i didnt know how to use any of the linux applications, so i used partitionmagic.  it went well).  but now if i try to mount it, it goes nutty.  i've been running around google for a while now but none of the proposed solutions worked.
i tried adding this to fstab

Code: [Select]

/dev/hda8            /apps                reiserfs   defaults   0 0  but it gave up with

Code: [Select]

mount: wrong fs type, bad option, bad superblock on /dev/hda8,
       or too many mounted file systems if i try manually (because it worked for other people)

Code: [Select]

linux:/ # mount -t reiserfs /dev/hda8 /apps
mount: wrong fs type, bad option, bad superblock on /dev/hda8,
       or too many mounted file systems as you can see, the same thing happens.
here's what i get with fdisk

Code: [Select]

linux:/ # fdisk -l

Disk /dev/hda: 163.9 GB, 163928604672 bytes

You have to format the ReiserFS partition.  P. Magic won't do this.

[Commander]

thanks for the hint! i formatted it with yast and added this line in the fstab file

Code: [Select]

/dev/hda8            /apps                ext2       acl,user_xattr,users,gid=users,exec 1 2 now the only problem is that a normal user (me) have no write permission.  is it possible to have write permission (and hopefully execution) in that drive as i do in my windows fat32 partitions?
thanks

[Calum]

yes, you need to set a value for umask. i recommend 022 which will set default permissions of 755 to everything that gets created on that partition. this will involve adding "umask=022" after "exec", comma separated, no spaces.


actually i just thought about this and it should not be necessary, have a look at this:

/dev/hda6        /                reiserfs    defaults         1   1
/dev/hda7        /home            ext3        defaults         1   2

so now i think on it again, normal users do not have write permission on those direcories either.

also i think on it further and realise that a normal user does not need to have write access to program files either, so whatare you actually trying to do here?

also, why not make the new partition be /opt instead of adding a new nonstandard directory to your filesystem?

Why are you mounting a reiserfs partion as ext2?

hang on:

/dev/hda5 on /mnt/mydocuments type vfat (rw,umask=0)

proc on /proc type proc (rw)
none on /tmp/jack type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)


so, is "83" reiserfs or ext3 then? it looks like i have a reiserfs / partition and an ext3 /home partition, but both show up as "83" using fdisk. what's up?

ok, i was looking into how the reiser partition got named ext2, and i found out that i formatted it with the wrong type.  so i formatted it again with reiserfs and now the fstab line looks something like

Code: [Select]

/dev/hda8            /apps                reiserfs   acl,user_xattr,users,exec 1 2 if i add any other items in the options, namely (gid=users or umask=022), i get the error "mount: wrong fs type, bad option, bad superblock on /dev/hda8, or too many mounted file systems" .
as for why i wanted this drive; i wanted it so i could install the applications that can be installed on any directory (matlab, jdk, firefox, thunderbird, sunbird, amsn, azureus....) and for downloading files into from bittorrent clients  (if i tried saving them in the mounted fat32 partitions, it started wining about not being able to set permission or allocate space)
any ideas?


ps. thanks fot the help so far

Try

Code: [Select]

df -h
Then try

Code: [Select]

umount /mnt/hda9 for example.

The partition shouldn't be /, so I don't expect problems there.

[Calum]

i don't know why you don't just symlink the /opt directory there and create another directory called something like /downloads and this way you can retain proper permissions for /opt and all the programs installed into it, and you could just "chmod  777" the /downloads directory.

HMMMMMMMMMMMM...

since you are writing to this partition/folder by a user, it would be consistent to make
/dev/hda8 mount at /home/$USER/apps instead of /apps .... but whatever.

So, i would assume you have done (as root):

# mkdir /apps


As far as i see all you should need to do is add this line to your fstab:

/dev/hda8        /apps           reiserfs    defaults         1   2


then make you (the user) own that directory.

# chown $USER.users /apps
# chmod 777 /apps

(replace $USER with your username and in some distros it will be $USER.$USER)

and then you should be able to read/write your user in that directory.

ok,  so i took the suggestions and did the linking to /opt.  it's working so far with no problem.
MoR:  thanks for the suggestion, i'll certaily try it out (even if it means having to track back )  but i have this nagging feeling that this wont work since fstab will probably overwrite any permission on that folder automatically.  but i'll certinly try it out once i get home.

just incase it doesnt work, i need to get something off my chest:  WHY THE HELL IS THIS SO COMPLICATED!?  ALL I WANT TO DO IS RW AND EXECUTE AS A NORMAL USER!  FOR THE LOVE OF GOD!

ok, that;s all.
thanks

as with a lot of things, it's a lot more complicated if you don't know how to do it.
