General :: Fix Filesystem Mounts That Are Missing The Nosuid Option Where They Should Have It?
Mar 22, 2011
I have these file systems mounted without the nosuid options set.
debugfs on /sys/kernel/debug type debugfs (rw)
/dev/mapper/KusuVolGroup00-DEPOT on /depot type ext3 (rw)
/dev/mapper/KusuVolGroup00-HOME on /home type ext3 (rw)
/dev/mapper/KusuVolGroup00-VAR on /var type ext3 (rw)
/dev/sdb1 on /home1 type ext3 (rw)
Do I set the option in the fstab files or set the files directly.

I'm trying to mount some file systems in the /sys directory with the nosuid option. Upon executing the command:
mount -o remount,nosuid /sys/kernel/security
or
remount nosuid /sys/kernel/security
/etc/mtab will show that they have been applied, but upon restart of the machine, the nosuid option is removed.
Soooo, the question is why are they being removed? Can /sys files carry the nosuid option?

I have been able to plug my iPhone in, and Ubuntu (10.04) has been able to see it immediatly. I was able to browse any pics etc. AND, I had the ability to SSH into it (Places>Connect To Server). In the connect to server dialoge, I clicked on the drop box and had several options including SSH. Now, there's nothing in the dialogue except "Custom Location". So, what happened? My iPhone no longer mounts and I have no SSH option! And I have not updated anything and made changes. I have tried 2 different cables and different USB ports.

I just discovered that you can automount an ext4 filesystem with acl enabled by running "tune2fs -o acl". (I knew about tune2fs but did not dare to use it until now). However, the acl mount option does not show up in /etc/mtab and /proc/mounts. Can I ignore this, or is there a way of telling the system about the actual mount options?
Edit: I can do "tune2fs -l <device> | grep acl | awk '{print $4}'" and if that isn't empty I can update /etc/mtab with "mount -f -o remount,acl <device>", but like the udev rule I previously messed with this seems lumberingly unelegant to me.

What the hell is wrong with 11.04? One day I wake up and find all of my mounts functioning properly, the next day many are missing. I've been running with the same fstab for years. The problem isn't only with cifs shares, but even with internal ext4 shares. I'm so disgusted I'm about to run to Windows after 10 or so years of prompting people to move to Linux.

In regards to compiling a custom kernel:
When using make menuconfig - under Device Drivers --> Character Devices --> there should be an option with the label "Enhanced Real Time Clock Support" (CONFIG_JS_RTC).
The problem is that this option seems to only show up while using the menu method when other options are either enabled or disabled and I've entirely forgotten what should be what. I swear fingered it out once.
This is on an older computer (P4) so HPET is no good.
You would think that disabling the HPET option would enable the RTC option but that does not appear to be the case.
I understand I can just add the option to the .config file and avoid this hassle but I'm very interested to know how to make this work.
To show my appreciation I will do something nice for you such as call you a nice name or tell you that you are pretty (or ugly if that's what you prefer).

I have multiple ubuntu machines and I connect to one through an NFS share. I have done this for a few years without issue. However, since re-installing ubuntu and upgrading to 10.4 I have a problem with my system hanging when the remote shares are lost.
Basically, I can power down the machine downstairs, and my main machine then has a fit. I can not open any folders in ubuntu, nor can I shut down. If I try and shut down the system hangs, last time it hung for 8 hours before I had to kill the power.
These are the lines in my fstab
I don't know what I've done wrong, or how I can prevent this from hanging. I have googled the heck out of this as well and can't seem to find an answer either.

why my df -h command is telling me I'm missing 18G?
***
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_aikifedora-lv_home
357G 272M 339G 1% /home
***
This was 'df -h /home' straight after a fresh install. It says it's 357G in size, but even though 272M is in use, it's telling me I have only 339G left available. Where did that extra 18G go?

I have a 6x1TB RAID5 set up for testing on ubuntu created with mdadm and formatted with an ext4 fs.
This is being shared over CIFS for windows clients. When looking at the fs from both the file box and the clients, it says 4.47TiB total capacity, and 4.24TiB free space. The only folder is Lost+Found which is empty.
I don't have much experience in Linux filesystems as of yet and I don't understand where this 300 gigs has gone!
Is it something to do with journaling?

I don't have a "CPU MHz" line in my /proc/cpuinfo. I wonder if this is because I installed a 32-bit Ubuntu (10.10, Maverick) on 64-bit (dual core) AMD hardware. Various apps depend on the "CPU MHz" value and simply refuse to run without it. Is it, indeed, a 32-bit software on 64-bit hardware thing? If so, is there any fix short of replacing (clean-installing) the whole system in 64-bit?
$ uname -a:
..... 2.6.32-27-generic #49-Ubuntu SMP Wed Dec 1 23:52:12 UTC 2010 i686 GNU/Linux
$ cat /proc/cpuinfo:

cpu family: 15

model name: AMD Turion(tm) 64 X2 Mobile Technology TL-58

Attached is a picture of my desktop.
As you can see, there is no wireless option, but only a wired one.
Does anyone know of anything that could be causing this. Just downloaded 10.10 today.

When I was running 10.04 I was able to select the sleep option in XFCE's logout menu and it worked perfectly. I've just done a fresh install of 10.10 and now the sleep option is missing. How can I bring it back?

I downloaded the release version of 11.04 desktop 32bit today and ran into a problem with the upgrade. Not sure if I missed a step or not, but when I booted the CD to do an Install of 11.04 desktop 32bit over 10.10 desktop 32bit I expected to see the upgrade option similar to what is in this link (red arrow pointing to it):[URL]... On my install screen all the other options were there except the upgrade.
Since I was on a schedule for this particular computer I am doing the Update Manager Network upgrade instead but I have 3 other computers to do as well. Any ideas on what I might have missed? Should I have booted to Live version first instead of Install then look for an upgrade option somewhere? I read something that alluded to that on a website.

I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?

I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

I have just installed XBMC (yum install xbmc) and noticed that the option where you can control it via the HTTP protocol is gone. Just as a curiosity I have installed it on my windows machine and the http server option is there. Does anyone knows what you have to do to fix this?

I recently installed Ubuntu 10.10 on my desktop which also have windows xp installed. After the installation I could boot to both Ubuntu and Windows. I then installed some updates from the update manager in Ubuntu 10.10 and after this the windows option in the grub boot menu is gone. The boot_info_script055.sh returned the following result
Boot Info Script 0.55 dated February 15th, 2010

=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #5 for (,msdos5)/boot/grub.

I've got a fresh install of 11.3 on a x64 machine. I've managed to work through most of the initial hiccups and get a smooth system.However I've noticed that the 'System Logs' option in YAST is missing. Has anyone else noticed this? Is there some supplimental package that I should install? If it was removed from 11.3, is there an easy way to find and read these logs?

Ubuntu Lucid not all the icons in the menus on the panel at the top of the screen are there any more.how do I get those back? I really miss my bookmarks icon, and the icons in the system menu. I don't care if the icons are there by default, I just want the choice of whether or not they are displayed.

I removed Evolution and replaced it with Thunderbird. I no longer have the option within the white envelope in the panel for compose mail, etc. I really liked this function but it appears to me to have been an Evolution specific function. How to make this work for Thunderbird?

just recently, while attempting to boot to windows 7, i happened to select the wrong boot option by mistake, that is the windows 7 recovery (something like that, cant remember it specifically, but the word 'recovery' is there). the option has been there eversince i installed ubuntu 11.04 on my system, of which i cant find the answer as to why it existed there. so once i selected it (which was by mistake), it took me into some recovery process which i abandoned as quickly. it restarted and the windows 7 option was no longer there. the windows 7 recovery option, however, is still there. How to get my windows 7 boot option back?

I'm testing out 10.04 on one of my partitions, and I love it. I have been using it exclusively for a while now, I have not logged into Windows since! Really don't care about windows anymore!However, yesterday I went to boot into windows... and I noticed the option to choose it is missing from my list! Maybe I'm just not getting to the correct list? The list I get shows like 5 different modes and versions of Ubuntu and something called Windows Recovery (which does nothing), but that's it.
