Networking :: Can Re-export Via NFS A Partition That Is NFS Mounted On Server?
Jan 8, 2010
I have a DHCP/PXE server behind a firewall. It mounts partitions on the file server on the corp. network on the other side of the firewall. Every box that PXEs also mounts partitions on the main file server.
I was hoping I could change them to mount from the DHCP/PXE server, so that server could cache and cut down on the requests through the firewall, as well as the sessions that the firewall must track.But it seams a little strange to try to export directories that are simply NFS mounts on another server already.

using suse 11.3 and kde 4.4.4 on the mounted fat32 partition I cannot change icons partition is mounted in fstab in this way:/dev/sda8/ /dati vfat user, users, gid=users, umask=0002, utf8=true, 0, 0.I can create files folders modify, move and save them on the partition but if I try to change the icon (in dolphin right click>properties>click on icon) of the /eros folder (or any other folder or link) system gives me
this error:impossibile salvare le proprieta' , non hai accesso sufficiente per scrivere su /dati/eros/.directory tha in english is something like this: impossoble save properties, you havent enough permission access to write on /dati/eros/.directory this happen also as superuser I remember that with suse 11.0 or 10.3 I was able to change icons on fat32 partitions, now with 11.3 I cannot, there ought to be a way to do what I did with the previous version with this 11.3 brand new ad more advanced version shouldn't it?

Is there a program that will reread the partition table and update the kernel even if one of the unmodified partitions is mounted? I installed my system on one partition, then I added another with free space. Now I want to format the second partition, but the kernel doesn't know about it yet. I tried sfdisk -R /dev/sda, but it refuses while the root partition is mounted. Is there anyway I can avoid rebooting?

I'm wandering if it is possible to set up a partition on a laptop's HD so that if I use a USB cable between it and another device, the partition would appear as an external HD on the device.
Old Mac laptops used to have the option at boot-time of sharing the hardrive via firewire (they might still have it, have no clue) I'm looking for something similar, but on a laptop with Linux running on a different partition.

When I powered-up my computer today I received the message that the home partition listed in /etc/fstab cannot be mounted and to press ESC to go to the recovery shell.
My computer is dual-boot, with Windows on the first hard disk (sda) and Ubuntu 9.10 on the second hard disk (sdb); I am using Grub version 1.97 beta4. The home partition is thus on sdb2 and the file system is ext4.
The /etc/fstab file contains all the partitions and has not changed since last October. Also, when issuing the command fdisk l, all partitions are correctly displayed, including the home that cannot be mounted.
Finally, the command fsck /dev/sdb2 quickly returns the result that /dev/sdb2 is clean!

I am trying to actually wipe my entire hard drive and figured it may just be easiest to format the hard drive and deleting the partitions. So when I go to System => Administration => Disk Utility => Select the Hard Drive => Click Delete Partition => And I get the error shown in my screenshots. What would be my best way to delete this partition and remove ubuntu completely for the time being. And yes I am using the latest RC. 10.04. However I don't suspect this is a bug.

I'm using LVM-based partitioning. I can not mount one partition. Here is some information I can provide.

This incident happened after I try to encrypt this partition and then an error message appears. If not mistaken, it contains an error number (I forget) and a warning which reads that can not remove the LABEL on the devices.

I would like to resize the /home partition but it is mounted and when umount is run, it errors with 'busy'.
System Configuration:
I installed jessie on a laptop with one SSD. I used guided partitioning and selected the whole drive with multiple partitions. The /home now takes up 420 GB. I would like to reduce that to 20 GB to make room for another partition.
What are the methods reduce this partition?

recently i did a fresh install of 11.3 on an ext4 partition. My data disk is a ext3 and the new system mounts it during boot.I can write to it but i can not execute programs from this partition.in fstab i can not find something like "noexec"permissions of mount folder looks ok for me. e.g. execute compiled "hello world"
me:~/datadisk> ./hello
bash: ./hello: Permission denied

I had my hard disk partitioned as below:-
Size Label Mount point File system
52 GB Multimedia /MM ntfs
52 GB Backup /ABackup ntfs
52 GB Extras /Extras ext4
27 GB root / ext4
60 GB home /home ext4
The problem is that I cannot access the /MM and contents. I tried Properties > Permissions and changed applied the changes to subfolders and contents too. Now I can access /MM but not the contents. All are marked with a lock logo.There are numerous folders/files.Changing the permissions individually is a hectic work.possible to do it in a command line/script?

I'm totally new with linux and Ubuntu. I've just installed 10.10 yesterday and since then it's been an uphill struggle These forums has helped me out quite a bit already so I hope you can continue doing it with this problem I have.I got a single drive where the bootpartition is ext4 and the other "storage" partition is a remenant from a windows 7 installation I had, with NTFS. Decided I wanted to give Ubuntu a try! Now i've run into permission trouble though, mainly because I wanted to set up an FTP server (oh what a struggle THAT's been, I have some stories... ). I've done a "mount --bind" so that I can reach different resources directly from my chroot. It turns out though that the mounted partition isn't giving anyone except the owner (me) permission to see the resources. FTPing into the server gives the mount points but gives a 550 error and can't list anything inside of them.It works perfectly for me just running it at the prompt or using the mount points directly in the Ubuntu GUI though (since I'm the owner/admin/whatever).
My intended solution that I've found was that people with NTFS drives did a few magic tricks with the line of text in Fstab so they could access their NTFS drives. Problem for me is that my sda3 mount isn't showing up at all in fstab, even though fstab is supposed to (as far as I know) show all mounted devices on there. All the while, I have my sda3 totally accessible from /media/Storage/. Any pointers as to why this is?After I installed Ubuntu, I just mounted the sda3 with the Disk Utility from System->Administation and didn't think much of it afterwards until now.What's the best course of action here? remount the ntfs partiton using fstab? Convert the ntfs partition into an ext4? I have a lot of data on there I want to keep as well.

I have a 500 G, where 80 are used for FC13. I added a new 80 G partiton, using Disk Utiliy, called it Backup, and I can access it when I am logged as root, When I log with any other user, even with all privileges (added almost in all groups), I get a dialog box requesting authentication.
I enter my user password, file manage just disappears as soon as dialog box disappears and I think it is a permission issue again.
In disk utility opposite to Device there is "dev/sdb", in mount point there is media/backup.
I opened fstab, I can not see an entry, here is the fstab :
Quote:
#
# /etc/fstab
# Created by anaconda on Wed Jun 16 00:58:19 2010
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
[Code]....
So what is the route to follow to follow to allow my user to access normally read and write to it without anu persmission issues

Every time I mount one partition manually as read write it works fine for a couple of minutes before reverting to read only. It still appears as read-write when I list the mounted directories but won't let me write to it. I have tried unmounting and remounting it, but after a few minutes it always ends up as read-only again.
$ mount
/dev/sda3 on /scratch type ext3 (rw)
$ mkdir /scratch/file

I have two ext4 partitions: one with Ubuntu 10.10 64-bits and the other just for storing files.When I log on to Ubuntu, my second partition is not mounted. Shouldn't Ubuntu mount my second partition by default (since it recognizes it as ext4)?If it should, why is this happening to me?If it shouldn't, how can I get my second partition to be mounted at startup? Should it be by using the same solution provided by prayag_pjs (first reply)[URL]

I've been working at creating a highly available set of host servers for a linux diskless boot cluster.Each host machine is fitted with redundant power supplies and two 1TB drives in a Raid-1 configuration.When I first started this project they each had twin 160GB drives. In my original setup I had both nodes acting as primary systems so that I could mount /dev/drbd0 to my /data directory and see changes immediately.It had worked in the past where I could make a file in /data on the first machine and it would show up in the /data directory on the second machine. One day this had stopped working where if I made a file on the first machine it would display on the second one until I unmounted /data and remounted it to the /dev/drbd0 disk.
This is when I bought the new disks and decided to start from scratch. The weird thing is that if I make a file on the primary and remount on the secondary to see it and then delete it from the secondary and THEN delete it on the primary, the primary throws no error however it goes into read-only mode because it knows that file was already gone.Below is my configuration file, sda8 is an 820GB partition which is used for all of the data I want to replicate, currently populated with ~10GB of data. Sda7 is my metadisk partition which is 500MB large clearly more than needed by drbd.Also you will notice "incon-degr-cmd "halt -f";" is commented out. This is because when I go to actually use it drbd throws an error when reloading the configuration and I'm not sure why that is either
resource r0 {
protocol C;
#incon-degr-cmd "halt -f";

Anyway i have a very old Mandrake server where a previous owner hosted mailboxes on. This server is getting very slow and does alot of e-mail related tasks like:popsmtpmxIt runs on sendmail (which is also very outdated...) and it doesnt seem to respond to its config files. And the whole smtp and mx thing leaves us with some really weird mail problems...So i want to implement it in our current mail setup in which i have it all on seperate servers:2 smtp server (dns roundrobbing) (postfix)4 mx servers (1 etrn) (postfix)1 webmail server (v-webmail) (just apache and connects to the pop/imap server)And 1 pop/imap server (postfix, dovecot)I also want to implement smtp authentication because of all the mobile clients i have to host... This is where it gets tricky.
I want to export the unix user table of the old mandrake server and import that into a mysql database. This database will be used to authenticate the smtp users.I also want the export of the unix users to import it to the other pop/imap server so users can logon to that server instead of the crappy Mandrake server.I would expect that the export from unux users to mysql (including passwords) is the hardest part. I googled it, but some of the stuff i found didnt seem to be very reliable, so thats where you guys kick in :-). So is this possible? If so, how can i do it?I know i should go with some kind of ldap situation but that seems a way bigger hassle then this setup.

We recently upgraded our NFS server from Centos 4.4 kernel 2.6.9-42.0.10.plus.c4 to Centos 5.4 kernel 2.6.18-164.6.1.el5
In our queue directory where we shuffle files to be processes some files will go missing.
Example structure
/Queues/Process1/subdir_xxx
/Queues/Process1/subdir_xxx
etc...
/Queues/Process2/subdir_xxx
/Queues/Process1/subdir_xxx
etc...
Where 'xxx' is a date/time string down to the second.
Each subdir entry contains a number of files, depending on load at the time.
What we see happening is that a subdir will appear empty from a client (ls -la shows . and .. ) but an rmdir will fail with a 'directory not empty' error. From all 7 clients (mix of Centos 4 and 5). However on the server the files are visible. If we 'touch' the files the clients will then pick them up and process them.
It doesn't appear that waiting any amount of time will make the files visible (we've waited 8 hours while testing).
We've tried different mount options, NFS4, etc. Nothing got rid of the issue. Changing one server to use CIFS however solved it. So it appears to be some bug in NFS.
The problem appears to be intermittent and random, we can go hours without seeing it, or minutes. I'd say it affects fare less then 1% of the files written.

Yesterday, I upgraded to the 10.04 verion of xubuntu. Looks fine. However, I keep my data on an NTFS partition of my dual boot laptop, and am finding that I can't access it.
I have a symbolic link to that mounted partition, and when I click on it, I can see the first level of folders, but I can't execute them (even though they seem to be set to 777) and I can't open anything...
