yet another fstab thread

There are some things I just can't figure out.

1) How do I execute fstab without rebooting?

2) I'd like to mount /dev/hdb via uuid, because I have two reiserfs exchange drives, one of them should be mounted with write permission for root only. How do I get the uuid? I remember using lshal to get the uuid for my usb device, but that's it.

er.. well. that's it

I saw ubuntu added a umask=0222 - option of the ntfs disk I had in my box while installing. What does the fourth digit do? Is it vital for something? I kept using this for my other ntfs drives, since 444 didn't work (would make more sense to me, since I can't write to it anyway)

My fstab, just for fun:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

proc            /proc           proc    defaults        0       0

#ex1
/dev/hda1       /               ext3    defaults,errors=remount-ro 	0       1
/dev/hda5       none            swap    sw          				0       0

/dev/hdc        /media/cdrom0	udf,iso9660 user,noauto		0       0
/dev/hdd        /media/cdrom1	udf,iso9660 user,noauto		0       0


/dev/hde1       /mnt/hde1		ntfs    umask=0222			0	 0
/dev/hde5       /mnt/hde5		ntfs    umask=0222			0       0

#/dev/fd0        /media/floppy0	auto    rw,user,noauto 		0       0

#ex2
/dev/hdg1		/mnt/hdg1		ntfs    umask=0222			0       0
/dev/hdg2		/mnt/hdg2		reiserfs	defaults			0	 2

/dev/hdb1		/mnt/hdb1		reiserfs   defaults			0       2

##usb-drive
/dev/sda1		 /mnt/sda1	vfat	defaults,umask=000 	0	0
/dev/sda2           /mnt/sda2	vfat	defaults,umask=000		0	0
/dev/sda3           /mnt/sda3	vfat 	defaults,umask=000		0	0

In my fstab file the code looks tidy... I use alot of <tab>
Anyhow.
hdg1 and hdg2 are on two different drives. So it just fails to mount one and mounts the other, or mounts none if it isn't in there, depending on what drive is in there at the moment. I guess this is alright.

Hello oskar,

You can use the command 'mount -a' to mount all devices depicted in /etc/fstab.
Also you can use the function 'LABEL' for linux device file systems on mounting.

Thanks,,

I knew I once knew this.
Going to check out that label thing, thanks.

---edit---
I must return to report I have the same problem with the label. I can't find it, and I don't know how to write it to an existing reiserfs filesystem. (you label the filesystem, not the partition, right?)

Hello oskar,

The directive LABEL is used for filesystems. We can assign a Label for an existing linux partition so that even if the HD is changed and connected to a seperate connector, the OS detects it.

Thanks,,

found it!

"blkid" shows the uuid of all the harddrives.
