Networking :: NFS Autofs Can't See Mounted Subdirectory?

Oct 21, 2010

I have a machine (mercury) on which /home/hyperhacker/video is a mounted external hard drive while the rest of /home/hyperhacker is on the internal hard disk. I have a second machine (konata) using autofs to automatically mount mercury:/home/hyperhacker in /mnt/mercury as needed. This works, except /mnt/mercury/video shows up empty.mercury:/etc/exports has: Code: /home/hyperhacker konata(ro,subtree_check)/home/hyperhacker/video konata(ro,subtree_check) and I've tried a few variations in konata: Code: $ cat /etc/auto.master

[...]
+auto.master
/mnt /etc/auto.mercury

General :: Copy Everything In A Subdirectory Across To The Relevant Subdirectory Elsewhere

Sep 16, 2011

At the moment I'm doing:

for i in mdx/[0-9][0-9].png; do cp $i ../../d_s_c/images/mdx ; done

But as well as the directory mdx, I also have other directories called ntt, etc.

How can I say 'For everything in a subdirectory, copy it across to the same subdirectory over at at ../../d_s_c/images'?

Ubuntu Networking :: Mounting NFS Share By Autofs?

Oct 28, 2010

I have a server, with a static IP of 192.168.1.17, that is running Ubuntu lucid sever edition and that exports some shares per NFS. Here is its /etc/exports:

Code:
/media/Share00 192.168.1.0/255.255.255.0(rw,nohide,insecure,no_subtree_check,async)
/media/Share01 192.168.1.0/255.255.255.0(rw,nohide,insecure,no_subtree_check,async)
/media/Share02 192.168.1.0/255.255.255.0(rw,nohide,insecure,no_subtree_check,async)
/media/Share03 192.168.1.0/255.255.255.0(rw,nohide,insecure,no_subtree_check,async)

[Code]....

However, autofs does not work: the /msrv directory appears and disappears when I start and stop autofs; but when I enter "cd /msrv" followed by "cd Share05" in the terminal, I get the "bash: cd: /msrv/Share05: No such file or directory" message after the second command.

Ubuntu Networking :: Automatically Mount NFS Shares Without Autofs?

Jan 24, 2010

Setup clients on a LAN to automatically mount NFS shares whenever the fileserver is up, without using autofs. Instead a simple bash script which checks if the server is up, and if the shares need to be mounted or unmounted is called by a custom upstart job. For a small office or home network populated with Unix-like computers (e.g., a few Ubuntu desktops or laptops and a fileserver), NFS (Network File System) is a good way to share storage space and centralise the backup of important documents. However, having a fileserver running 24/7 is often overkill for such a setup.

One way to have clients mount NFS shares automatically when the fileserver is turned on, is to use a package called autofs. Unfortunately, there are a few unresolved issues with using autofs in combination with NFS. In my case, when autofs tries to mount NFS shares when the fileserver is turned off, the Gnome desktop, and Nautilus in particular, becomes extremely unresponsive, regardless of the options used. Attempting to mount the share manually from the command line when the server is down however, does return a message of failure quite promptly, without hanging the desktop.

To solve this issue, I wrote a simple bash script that is run through the upstart system. The script simply checks if the fileserver is up, if the shares need mounting or unmounting, and then sleeps for a while before checking again. This works out quite well, so I decided to share this information in case someone else runs into these issues. PrerequisitesThis howto assumes that you have an NFS server set up with shares exported, and one or more clients capable of mounting those shares. For more information on setting up NFS shares and mounting them on a client from the command line, see: SettingUpNFSHowTo.

Clients should be able to ping the server to determine if it is running. Naturally, you need administrator access on the clients to install the script and upstart job outlined below. This script assumes that the directory paths of the shares match the location where they are mounted. In my case, the fileserver has two shares: /media/Storage and /media/Backup. On the clients these shares are mounted on the same paths. If your setup deviates from this, the script needs some modification. The script From the desktop of one the clients, paste the following bash script as a new file in your favourite text editor:

Code:

#!/bin/bash
# The hostname or IP-address of the fileserver:
FILESERVER="myfileserver.local"
# Check every X seconds (60 is a good default):

[code]...

Now adjust the FILESERVER variable. In this example, my fileserver is called myfileserver. By default, Ubuntu sets up your networking environment in such a way, that computername.local can be used to reach that computer over the local network, so the network name for myfileserver is myfileserver.local. Of course, you can also use the IP-address of the server. Next, change the MOUNTS variable to match the NFS shares exported by your NFS server. MOUNTS is an array; multiple entries are separated by spaces. So if you have one share exported as /media/MyShare, that line would look like this:

Code:

MOUNTS=( "/media/MyShare" )

An advantage of mounting shares in /media, is that they automatically show up as mounted drives on the user's desktop. Note that this howto assumes that you use the same paths for the share on the server and client side! Save the script to your desktop with an obvious name. In this example we call it mount_my_nfs_shares. Open a terminal and cd to the desktop. Make the script executable by calling:

Code:

chmod +x mount_my_nfs_shares

Next, move it to a place where it can be called by our upstart job, but also from the console to test. A good place to put such custom executables is /usr/local/bin.

Code:

sudo mv mount_my_nfs_shares /usr/local/bin

This script uses the logger command to tell the system's log what it is doing. To test this script, open up two terminals; in one, execute the following so we can monitor the log messages:

Code:

tail -f /var/log/syslog

In the other, simply execute mount_my_nfs_shares. If the script works, your shares should show up on the desktop and the computer:// location in Nautilus. If the fileserver goes down or becomes unreachable, the shares should disappear, and reappear when the fileserver comes back on-line. If this works, move on to the next step. Installing a custom upstart job The next step is to have the clients automatically run the above script when they are booted. We can use upstart for this. Create a new text file, and enter the following:

Code:

# mount_my_nfs_shares - mount NFS shares on fileserver, if present
description"Mount NFS-shares"
start on (filesystem)
respawn

[code]....

How the script works The script enters an eternal loop and keeps checking if it can reach the fileserver once every minute (unless you adjust the INTERVAL variable). If it can reach (ping) the fileserver, it checks if the mounts are already mounted by searching for them (grepping) in the output of mount. If they are not mounted, it tries to mount them. Else, if the server is down, it looks in the output of mount to see if these mounts exist. If they do, it tries to unmount them with the -f flag (useful for unmounting unreachable NFS shares).

Networking :: Autofs No Longer Working - Finding Source ?

May 23, 2011

After several days of searching, reading and re-installing, I'm at a complete loss as to why autofs has suddenly stopped working.

Basically, I can see the shared folders on the host computer but as soon as I try to cd into the folders I get "-bash: cd: [directory]: No such file or directory" (where [directory] = shared drive).

The setup was working before and the same exact setup is being used and is fully functional on another computer.

I'm running Ubuntu 11.04

Here is the content of auto.cifs:

Code:

Here is the content of auto.master

Code:

And credentials are stored in /etc/auto.smb.goblin (where goblin = name of windows computer sharing folders).

When I do "ls -l /home/shoryuken/TerraDrive/goblin" I get:

Code:

Now if I try to "cd" into any of the shared drives (like D-Drive, GW_Share or TerraDrive) I get the following:

Code:

A second or subsequent attempt at "ls -l" results in:

Code:

Note the question marks that are now everywhere.

I'm not sure where to look to find out why this is failing. The shared drive are visible, but then disappear when I try to access them. The same exact setup, on another machine works perfectly fine.

Ubuntu Networking :: Autofs And Nautilus Replacing Fstab - Browsing?

May 6, 2011

Because of NFS traffic congestion, I am trying to use autofs instead of fstab(NFS) to mount /home and /data directories on our system (from a NFS server). I have it up and running - users can log in and their /home directories work fine. However, when they need to save a file (openoffice or nautilus) they cannot see the directory tree to locate folders for saving. I have tried setting the --ghost option in auto.master, and I have tried commenting the BROWSE_MODE in /etc/default/autofs. But no luck. Using the terminal, I can go a folder and see subfolders using ls -la. They then appear in Nautilus, but later disappear. Since this is a school network, I can't expect teachers and students to use the terminal to save files. They are used to using Nautilus, with our regular NFS mounts.

Ubuntu Networking :: Ubuntu Samba Seperate Subdirectory Permissions?

Jul 18, 2011

Okay so I decided to turn my NAS over from Windows Server 2003 to Ubuntu 11.04 Desktop. This was a big leap for me as I'm still quite new to Linux, but I thought it'd be worth it. I've got everything working pretty good such as Apache2, SSH and converting my disks to ext4.My problem however is Samba. I've got it to share out my hard drives okay but haven't got effective permissions just yet. All drives and the documents storage folder have write permissions by everyone at the moment but I'm the only one that really uses them in the LAN. What I need to do is be able to do what can be done on Windows Server, create a share, set who can access it (user or group) and then under Windows Explorer change folder permissions so say Elliot can access the share and folder Stuff but Sandra can access the share and not Stuff. Which is easy enough on Windows but I need the folders under that share to work the same with Samba. Here is how the drives are mounted and where the documents folder is located:

"Samba share name" at "mount/folder"
"datastore1" mounted at "/srv/ds1"
"datastore2" mounted at "/srv/ds2"

Ubuntu :: 10.10 - Cannot Detect Subdirectory (Bash CD Error)

Dec 21, 2010

I'm trying to change to a subdirectory:
Code:
tony@advent:~/scratch$ cd Home-Arch
bash: cd: Home-Arch: No such file or directory

So I list the contents of the current directory:
Code:
tony@advent:~/scratch$ ls
duhome Home-Arch qcad_1.dxf qcad_1.svg runme stdout

OK, I assume I have mis-typed the subdirectory name in ways I cannot detect, so I copy the sub-directory name from the output of the 'ls' command, while within the terminal window, and paste it into the next 'cd' command:

Code:
tony@advent:~/scratch$ cd Home-Arch
bash: cd: Home-Arch: No such file or directory

I browse the directory and sub-directory in Nautlius - everything is there where I expect it to be. The folders/files are not hidden. What is happening here?

General :: Filter Find And Du By Content Of Inner File In Subdirectory?

May 30, 2010

I have the following command that I run on cygwin:

find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | xargs du --max-depth=0 > foldersizesreport.csv

I intended to do the following with this command: for each folder under /d/tmp/ that was modified in last 150 days, check its total size including files within it and report it to file foldersizesreport.csv however that is now not good enough for me, as it turns out inside each

/d/tmp/subfolder1/somefile.properties
/d/tmp/subfolder2/somefile.properties
/d/tmp/subfolder3/somefile.properties
/d/tmp/subfolder4/somefile.properties

so as you see inside each subfolderX there is a file named somefile.properties inside it there is a property SOMEPROPKEY=3808612800100 (among other properties) this is the time in millisecond, i need to change the command so that instead of -mtime -150 it will include in the whole calculation only subfolderX that has a file inside them somefile.properties where the SOMEPROPKEY=3808612800100 is the time in millisecond in future, if the value SOMEPROPKEY=23948948 is in past then dont at all include the folderin the foldersizesreport.csv because its not relevant to me.so the result report should be looking like:

/d/tmp/,subfolder1,<itssizein KB>
/d/tmp/,subfolder2,<itssizein KB>

and if subfolder3 had a SOMEPROPKEY=34243234 (time in ms in past) then it would not be in that csv file.so basically I'm looking for:

find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | <only subfolders that have in them property in file SOMEPROPKEY=28374874827 - time in ms in future and not in past | xargs du --max-depth=0 > foldersizesreport.csv

Networking :: User Mounted Nas ?

Jun 5, 2011

I've asked about this elsewhere and have made some progress.

I have added this line to fstab

Code:

Doesn't appear to be a problem with this until I come to mount it from the console in kde. What ever type of mount command I use I have to run it in su mode for it to work. Doesn't matter if I use mount.cifs. Same problem. Mount then requests the nas access password for user john. I can then access the nas from my desktop. Seems a little crazy to use the root password to obtain the users nas password so what have I done wrong? One solution might be to run a shell script that has root rights but I understand this can't be done.

The reason for wanting to do it this way is problems with none kde programs rw to the nas and click launching etc. There seems to be something in KDE locking this out. Same problem with samba. Opensuse 11.4 kde4.6.0
