Ubuntu :: Create A Dir That Points To Another HDD
Jun 30, 2011
I am currently running a lot of simulations and am always interested to speed things up a bit. My workstation has 2 hdds, 1 ssd-drive (sda1) and 1 mechanical platter drive (sdb1). Of course, most of my data are on the mechanical drive and the ssd is mostly used for booting.
However, to speed things up a bit, I wonder if it is possible to create a pointer or link in a directory residing within the mechanical drive, which will write the data, in reality, to the ssd instead. For example,
Code:
/home/me/sims/data/dump
would normally reside on sdb1. But I would like it to point to a mount point of the ssd instead, e.g.,
Code:
/ssdtemp/dump

I have a large collection of files on a computer (tallgrass) and tallgrass is running an ftp server, which I have the username and password to. There is about 600 GB of files on tallgrass that I need access to, but I don't have a big enough hard drive. I need these data files to run a cpu-intensive calculation, and my CPU is significantly better than tallgrass' cpu, which is why I want to do it on my computer. (Tallgrass also doesn't have enough RAM.) What I would like to do is create a "symbolic link" on my hard drive that will point to the directory containing the data on tallgrass. Read-only is perfectly OK. This way I could read from mylink/data0001.dat and it would read from the file data0001.dat over ftp from tallgrass. I shouldn't have any speed issues because tallgrass is on my 1 Gbps LAN. Is there a way I can do this?

At work I use Ubuntu and one nice thing about it is that it creates mount points for removable drives automatically.
In Slackware I can set up XFCE so that it mounts drives when they are plugged in, but only if they're already specified in the fstab (which means I must have used them and set them up in advance).
This is becoming a problem now that removable usb drives of all sorts are so common.

Ubuntu 9.10. I have a problem - when I mount other partitions of my hdd or the system automounts usb disks these are mounted in /media directory with permissions 0700. So there are two problems there:
- When I switch user on my desktop to another that user can't read data from the usb disks
- I can't share data through network because smbd doesnot have read permissions on the created mount points
I think editing /etc/fstab is wrong way, there would be more right way to change permissions on mount point. I tried to change/add parameters umask, allow_other in gconf-editor (/system/storage/default_options, subsections vfat and ntfs-3g) but that does not show any results. Article [URL] recommends Open Places → Computer. Every volume except the generic File system one should have a Drive and Volume tab in its properties dialog where you can set mount options. But I did not find those tabs. Where should I set option to mount usb disks with permissions rwx for every user of my system?

I have wireless G and N access points in my house. The N network is set to allow only N connections. I have a Lenovo laptop with a Intel Wireless N chip in it, and after one of the 10.10 updates it stopped connecting to my N access point. The G access point works just fine.
The logs for the Wireless N access point alway show "Bas Password." I am having the same problem with either NetworkManager or wicd.

Installed 10.10 maverick on my compaq mini 110, activated the restricted STA driver... But under the networking drop down it shows wireless as enabled but I cannot actually see any networks, there should be about a half a dozen to see. Works fine under windows. Before the restricted drivers are activated ifconfig shows eth0 and after eth0 and eth1 but when I do iwscan eth0 or eth1 it tells me this action is not supported! I have tried reinstalling from cli but no difference?

I'm using Zorin OS 4 Lite, which is a variant of Lubuntu 10.10. For some unknown reason, the desktop shortcut on PCManFM is pointing to my home folder, so I have all my personal files covering my Desktop (kind of annoying to be honest ). And when I try to add a shortcut to the Desktop it adds it to my home folder instead. Seems like there's some kind of hard link between the Desktop shortcut in PCManFM menu and my home folder. However, I can't find where it is or how to fix this. Has anyone else had this problem? How do I fix this?

I am having trouble connecting to 1 particular wireless hotspot. It used to work in Ubuntu 10.10, but after upgrading to Ubuntu 11.04 it sees the Access Point, tries to connect but never succeeds. I can however still connect to my home router. Both use WPA2, both have a good signal. I have an ASUS UL30a laptop with a (output from lspci): Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) NIC I was thinking of installing the linux-modules-backport-net package?

I have two wireless access points in my home network. A Linksys upstairs and a Watchguard Firebox downstairs. The Firebox acts as the gateway for my network to the internet (well, the ISP's router anyway). I invariably use my Hardy Heron installed HP laptop downstairs, less than 10ft from the Firebox. The signal bar for the Firebox shows three bars, the linksys just one. So, why the heck does my Ubuntu insist on connecting to the Linksys everytime?! I can manually switch it afterward but still, it's annoying.

Is there away to view wireless access points without being connected. I am having trouble getting connected to my wireless DSL modem. I have no problems connecting with Windows Vista. Just can not get Ubuntu 9.10 to connect. iwconfig says no associated with access point. I can connect with ethernet cable.

I have figured out manually setting the swap partition and setting "/" as the mount point for the primary partition during install. If during install, I want to create another partition to keep the OS separate from installed programs and such, to be able to do a clean install every 6 months and not loose everything (or anything) I have done prior.

I am having trouble with the advanced partitioning, I dont know what any of the mount points are for. I have a 64GB SSD which I want to use only for the boot files, and I have a 640GB which I want to place everything else on, as to preserve the life of the SSD. How should I configure my mount points/partitions in the ubuntu 11.04 installer?

I have an Ubuntu 11.04 laptop that I use to connect to a Windows 7 server. Everything was working fine until the hard drive on the server crashed and it was replaced with a backup. Now I intermittently lose access to the shares with Nautilus giving me the following message:
"The folder contents could not be displayed.You do not have the permissions necessary to view the contents of Folder"
When I look at the mount points in terminal I see the following:
drwxr-xr-x 5 root root 4096 2011-07-08 13:12 .
drwxr-xr-x 23 root root 4096 2011-05-03 11:17 ..
d????????? ? ? ? ? ? Folder
Where Folder is the mount point.My fstab looks like this, although I must point out that I have tried virtually every possible permutation with no change.
//10.35.1.110/Share /media/Folder cifs rw,_netdev,iocharset=utf8,credentials=/root/smb/credentials,uid=1000,gid=1000,noperm,file_mode=077 7,dir_mode=0777,sign 0 0
Sometimes the permissions will revert back by themselves, sometimes I need to umount and mount to get back in.I have tried deleting and recreating the mount points. No change.It is driving me up the wall, I have tried everything I can think of, installing/uninstalling winbind, the fuse modules etc etc. I use this machine as a production machine in a heterogeneous environment and everything works awesomely except for this. I love Ubuntu, I can't even think of booting Windoze these days but not being able to access the network shares is a right show-stopper for me.

I'm fuming about this again after doing my third install of 11.04, this time on one of my laptops. Why was the ability to edit mount points taken away in the 11.04 "Allocate Drive Space" portion of the custom install? In earlier versions, you could choose a mount point in the file system from a drop down (i.e. mount this partition as /, or /home, or /opt, etc.). You could also enter your own location to suit your needs. This allowed me to do tricks like mount my home partition under /media/home, to prevent my settings being clobbered by the installer (later, after integrating the settings created by the installer with the settings in my home directory, I could edit fstab to mount the home partition in its rightful /home location). Or to put my windows partitions under /media/WinXP or put my old Linux parition under /media/oldlinux. I could do whatever I want. Now, I have limited options. I can only choose a location from the drop-down. I cannot edit it. Want to mount a partition under /media/home? Tough. Want to mount Window under /media? Nope. Can't. Instead, if I select an ntfs partition, I only get the choice of mounting it under /dos or /windows. WTF do I do if I have three windows partitions (like I do on my desktop)?
Listen, if I'm doing a custom install, and I know enough to partition my drive, don't you imagine I don't need the mount point option dumbed down for me? If I've gotten to this point, I obviously know what I'm doing (or, if I don't, I'm already screwed bcuase I'll probably nuke a partition that I want to keep)limiting my choices here is stupid. I know, I can clean this up afterwards by editing fstab or using some other tool but my question is, why should I have to? What's the logic in removing this options from the user?

I have JDK 1.6 update 13 installed on my machine from binaries. For my java web applets to work, I had to install JRE 1.6 update 12 from the Debian repos. I downloaded a webstart app the other day that should install a programing emulator for me, but it can't seem to find my JDK or my version of Netbeans (everything built from binaries). On another forum, someone suggested that the JRE was the problem, so we linked every referece we could find to a JRE to my JRE in the JDK folder. JAVA_HOME, my PATH and even the /usr/java directories point to my JDK. For some reason, if I log into other accounts, every variable seems correct, but the account still points at the old JRE? My solution was just to remove the old JRE so everything would be forced to look at the newer one, but I can't every time I try, I am told that Open Office and several libraries will be removed also. Is there some way to remove just the old JRE and its two basae pacakages without the rest of my programs?

want to create a iSCSI connection which mounts /home directory to a share on my NAS via iSCSI. Does anyone know if this is possible on a RHEL 5.4 machine? I am building the server from scratch and then creating the iSCSI mount point in /etc/fstab. After the /home directory is mounted on the mail server, I will copy all the mailboxes over to the /home directory via iSCSI.

I'm not exactly sure if this should be here and not in the Hardware & Laptops section, but seeing as my only problem is with WiFi, I'm guessing this is the right place. Under Ubuntu, my laptop (an Asus K42Ja, more details below) can see wireless networks normally. However, when I attempt to connect, it fails to establish a connection. Under Windows on the same laptop (dual boot), no problems are experienced.
According to this, there's a firmware bug in my wireless chip which causes connections to get dropped. I'm not getting connections at all, but I still tried the workarounds on that page with no luck. The router is a TP-Link TL-WR340G. My previous laptop, a really old one from 2003 running Ubuntu 9.10 was able to connect to that router without problems. The wireless card was Intel on that as well (but, of course, much older). The router is set up to use WPA for security. I didn't use WPA2 as I read something a while ago about problems with WPA2 and some Linux distros. Please correct me if I'm wrong here.
If anyone's curious, I'm posting this on Ubuntu, via an ethernet cable to the router mentioned earlier. Some tasty technical bits: dmesg (the latter half of the "timed out" messages is me retrying after double-checking the WPA key)

Have openSUSE 11.1 and (AFAIK) KDE 4 on an older notebook; worked OK for weeks, then booting became a problem and the OS seemed to go to sleep between keystrokes: now the cursor stops blinking, the clock stops running, and nothing happens after clicking a radio button until the mouse moves. Am now 25 minutes into a reboot, hung at "Unmounting file systems" but it also hung for a while when changing run levels. Is this related to the stability problems with 11.1 I've read about? Possibly KDE? Where would I adjust a config to use kde 3.5 rather than 4?

i want to have 2 partitions. one is called system. the other is private.
in the private partition i've got some folders i want to mount into system as system folders.
folders in private:
- www
- home
mount points in system:
- /var/www
- /home
is this possible? cause it seems that you can only specify a whole partition to use for a mount point and not a folder in a partition or am i wrong?
i run ubuntu server.

When I insert an SD card in the reader, slackware creates a mount point and mounts my card volumes. On unmounting the volumes, the mount point vanishes. How do I achieve this manually?When I attempt to mount a volume using the mount command, the mount point folder must exist and the folder does not vanish on umount. Is there a way to create a mount point if it does not exist? and ensure that the folders vanish on umounting?
