what command remount one filesystem mounted?

thanks

man mount
remount
Attempt to remount an already-mounted file system. This is commonly used to change the mount flags for a file system, especially to make a readonly file system writeable. It does not change device or mount point.

this is right?


mount -o remount /dev/hda3

thanks

Well you can specify the mount point or the device name.
In fact you can add the options you want while remounting like this
mount -o remount,usrquota,rw /mnt/new
where the usrquota and rw are the options newly given while remounting(just a practical case where remounting is really useful)

I do not think you want to use "mount -o remount" . That is for mounting the same drive in a second place while it is still mounted in the first place. I think what you want to do is mount a drive that you unmounted.

To mount a drive (or partition) just anywhere you have to become root with "su". You have to know where you want to mount it, and what it is called. If you have a directory in /mnt called "win" you can do this:

mount /dev/hda3 /mnt/win

hda3 is the second partition on the second hard drive. You have to be root to do this. To mount it as a regular user, the partition and mount point have to be listed in the file /etc/fstab. Try this:

cat /etc/fstab

You should see something in that mess like this:

/dev/hdb3 /home/chuck/Misc ext3 defaults,user 0 1

This says that my third partition on the second hard drive can be mounted on the directory /home/chuck/Misc. If I want to mount it manualy, I can do this as a regular user:

mount /home/chuck/Misc

And it mounts hdb3 on /home/chuck/Misc. Try it and let us know if it works.

Good luck

I forget of the "point mount" above (fist post)
so, the complete command is (if this is right):
mount -o remount /dev/hda3 /mnt/quota

my drive is mounted in /mnt/quota

I activate quota in /dev/quota editing /etc/fstab
so I must remount my drive, but I don't want unmount and mount my drive again.

I'd like to remount my drive, so I used:
mount -o remount /dev/hda3 /mnt/quota


This is right (mount -o remount /dev/hda3 /mnt/quota)?


Thanks again for all helps!!!

Not exactly
You can use remount option to specify more options to an already mounted drive.
For eg if you have mounted a drive as ro and you want to mount it rw you can use
mount -o remount,rw
if you want userquota enabled
mount -o remount,usrquota

but what command only remount one partition mounted?

this is right?
mount -o remount /dev/hda3 /mnt/xxx

thanks
