General :: Simple Way To Umount NFS Mount In System?

Oct 25, 2010

I've mounted a share using standard nomenclature for the NFS mount command with the following command line:

mount -t nfs -o rw {IP address1}:/ /mnt_for_70 / {IP address2}(rw)

mnt_for_70 is a mount point I created on {IP address2}

I'm confuse and want to be sure I use the correct command on the correct host to correctly umount the nfs share.

Would I execute umount /mnt_for_70 on {IP address2}

Not sure if such a simple command will work. As this is a semi-production host pair, I hesitate to just umount so simply & I have no test systems to try this on...

General :: Mount And Umount As User Without Fstab?

Jul 19, 2011

I am writing this software that creates virtual block device nodes almost like loop does. I need to allow non-superusers to mount and umount filesystems from these devices. I don't know the names of the block device nodes beforehand so i can't use fstab entries to add "user" or "owner" flags there.

Currently i solve this by providing a small suid helper tool that verifies that this is indeed "my" block device the user is trying to mount and then just call /sbin/mount or /sbin/umount to do the job. This is definitely better than setting a suid bit for the whole program but not really perfect.

Debian Configuration :: Can't Umount Ramdisk After Loading New Root File System

Feb 1, 2010

I have built a kernel with a ramdisk(ramdisk.image.gz) included. Also in the kernel command line I specified root=/dev/ram0. I am trying to use this ramdisk to load a loopback file as the root filesystem off a fat partition. This is /sbin/init from the ramdisk.

#!/bin/sh
mount -n -t msdos /dev/mmcblk0p1 /mnt
losetup /dev/loop0 /mnt/linux/linuxdsk.img
mount -t ext2 /dev/loop0 /mnt2

[Code]....

The problem is both umount and blockdev report "device is busy". I want to free up this RAM any suggestions?

OpenSUSE :: Dolphin Services - Get Mount / Umount Option Under Right Click Services Menu

Dec 7, 2010

So I want to get mount/umount option under right click services menu. I went to Dolphin -> Settings -> Configure Dolphin -> Services -> Download New Services and from there I installed KDE CDEmu Emulator and MountISO. But neither of them is showing up in actual context menu. Neither in Dolphin -> Settings -> Configure Dolphin -> Services for that matter. I tried to install them as normal user and as a root. I went to have a peak in /usr/share/kde4/services/ServiceMenus/ but they aren't there as well... It's just me or lots of things seems to be not quite working in 11.3?

Server :: Simple Mirroring Networked File System?

Apr 8, 2010

I have two web servers. One is active and one is in reserve. I keep the user data (web pages) in sync by running rsync every 10 minutes or so. This copies any changes from the active machine to the reserve machine. But, it's slow, only gets changes every 10 minutes, bogs down the disk, does strange things to files that are changing during the rsync process etc...

I want something that will automatically copy any changes from the active server to the reserve server as they are made. IE I hit 'save' on the active server, it copies the file to the reserve server. Simple!

I've been looking around and I see GFS which is really vastly more complicated than I need. I'm happy with read-only access on the reserve host, so I don't need distributed lock management.

I could theoretically implement this by setting inotify watchers on every file and running an SCP or rsync command when a file gets saved. So, it can't be that hard.

I do not need a true networked file system, as in something I mount over the network. I just want something to keep my disks in sync.

General :: Mount A Filesystem When The System Boots?

Dec 21, 2009

I'm trying to mount a filesystem when the system boots, so i won't need to mount it everytime..

So what I did was copying the line of the filesystem I wanted to mount on startup from /etc/mtab:


Code:

And pasted it as it is, in the /etc/fstab file. when the system booted, it didn't work. not only that, I wasn't able to mount the filesystem at all, (it gave me some kind of an error) so I removed the line from fstab file and it all back to normal. how can I mount this filesystem on boot? (i'm using Fedora 12)

OpenSUSE Network :: Nfs Server On 11.2 - Mount.nfs: Mount System Call Failed

Apr 29, 2010

I've tried to get an opensuse box I have to share a directory via NFS. I've failed each time, but I thought that the third time, I'd enlist some help from the forums, if I could. how do I know that the nfs server and not the client is the problem? Short answer is: I don't! That's why nfs (and many netwrk problems) are laborious, you're troubleshooting needs to take place at both source and desitination. Next question, what do I have set up so far? Well, I did download the nfs server kernel stuff (two months back) and /etc/init.d/nfsserver start seems to get set up OK. No errors and the daemons nfsd, idmapd, mountd area all running. So, I *think* that part is OK. I have the share set up properly in /etc/exportfs and have "exportfs -r" it.

OK, now onto the trickier stuff: the client and iptables. On the client pinging to the nfserver box is perfect, and I have rpcbind running. the reported error is "mount.nfs: mount system call failed" though from experience nfs errors don't mean a whole lot.However, I will go off and check now and see if I need a mountd running on client-side too.Then there's iptables .... ouch, that could be a long and painful trek. I don't see any specific ports being blocked, and it's the iptables that the default v11.2 opensuse came with. I did turn them off and the problem was the same, so whether wishfl thinking or not, I'm hoping it's not an iptables issue.

General :: Mount A File System (/dev/sdb) As Ext3 (rw,acl,user_xattr)?

Jul 15, 2009

I'm trying to mount a second hard drive as a ext3 (rw_acl,user_xattr). I type the ff.:

# mkfs.ext3 -c /dev/sdb1(it seems to create a file system from this 2nd HD)

then type:

# mount -v /dev/sdb1 / type ext3 (it seems to mount it)

But when I check the ext3 systems with typing:

# mount -t ext3 (to check the list of ext3 devices, it gives me this)
/dev/sda1 on / type ext3 (rw,acl,user_xattr)
/dev/sda2 on /home type ext3 (rw,acl,user_xattr)
/dev/sdb1 on / type ext3 (rw)

How can I make /dev/sdb1 on type ext3 as (rw,acl,user_xattr) as the others?

General :: Boot From USB And Independently Of Host System Mount Pen Drive

Feb 16, 2010

I've for quite a while been going forward with making my own linux system with a purpose of being USB bootable. A lot of it has been taken from LFS and molded to my needs. The purpose of this is to, most of all, learn. My aim is to have a small linux system, bootable on most systems and able to run burnintest in textmode. This will be run of a vfat formatted pen drive with syslinux. The rootfs is run from a ext2 image file. My current image is bootable and is able to run burnintest, I do however still have some polishing to do.

I began this project by using uClibc and my image would be tiny enough to be run from a single initrd (20mb ~). What I didn't consider is the fact that burnintest is pre compiled using glibc, so had to re-do everything with a different c library.. After doing this I realized i no longer would be able to boot simply from ram as loading ~80mb to ram takes quite a lot of time during boot. I'd really like to keep the rootfs in an image file for easier management and I so far haven't found a way to mount this roofs image.
