I am curious if mounting a directory inside an already mounted directory is considered safe? I have done this on an Ubuntu server before but never thought to ask if it could cause problems.An example:
/dev/mapper/Raid5-VMStorage on /var/lib/libvirt/images
/dev/mapper/Raid1-SpareStorage on /var/lib/libvirt/images/Workstations
I'm having a bit of an issue with Lucid installed via Wubi. I stuck the OS on its own partition (30 GB in size), and don't store any large files in the Ubuntu file system (when I download something large I move it to another hard drive.) I don't have anything wacky or esoteric installed on my system.
I've been consistently having a problem where, after a few hours or a few days of being booted up, Ubuntu warns me that my available HD space is dangerously small. The amount of available HD space Ubuntu sees then shrinks from a few GB to nothing within a few minutes, and the only way I can seem to solve this is to reboot. Taking a closer look at what's happening, my Home folder balloons in size until there's no more writable space recognized. But there are no files being created or added to, so it looks like there's a bug of some sort. This SEEMS to be correlated with watching videos (or maybe it's the pulling of large files from a mounted directory into RAM? My videos are all on another HD, as mentioned before). I can generally go a few days without getting the "low space" message, but I can't seem to make it through a full 2-hour movie without getting the error.
I am trying to get NFS mounts working properly using autofs, but I'm only getting partially results. I have an auto.master set up for indirect mounts and a list of map files for each entry. Forgot to mention that when I mount the directory using /etc/fstab or setup a direct mount in /etc/auto.master I can see files in the mounted directory...
View 10 Replies View RelatedI have 3 disks in my PC which are partitioned equally as I use them for Raid 1.The first partition on every disk is a simple ext2 partition for booting. No Raid there. So I mount them as /boot and /boot2 and /boot3. So I can backup my /boot to the other boot directories. That worked for some month and this morning I just want to look if all directories have enough free space left. So I did a df -h and got this:
Code:
Dateisystem Grove Benut Verf Ben% Eingehängt auf
/dev/mapper/system-root
6,0G 301M 5,4G 6% /
udev 1,5G 292K 1,5G 1% /dev
/dev/sdb1 122M 29M 87M 25% /boot
/dev/sdc1 38M 21M 16M 59% /boot2
...
/dev/sda1 122M 29M 87M 25% /boot
As you can see /dev/sda1 and /dev/sdb1 are both mounted on /boot
Here is what mount says:
Code:
/dev/sdb1 on /boot type ext2 (ro,acl,user_xattr)
/dev/sdc1 on /boot2 type ext2 (ro,acl,user_xattr)
...
/dev/sda1 on /boot type ext2 (ro,acl,user_xattr)
This is no Problem for me as I could just remount it correctly, but I would like to know if this problem is known. I did not change anything by now and this PC is a server which is running 24/7, so I can deliver more debugging Information if someone is interested.
I wanted to set ACL for a directory. For that it is important that the device should be mounted as acl on that directory.
But I do not want to add the acl mount in /etc/fstab. So I am tempoararily mounting the device to some temporary directory as acl and setting ACL and then unmounting it. Then, I'm mounting it to the original directory.
The code is below:
tmp="/tmp1/backup"
orig="/mnt1/backup"
dev="/dev/sda2"
mkdir -p $tmp
[Code]....
The group is being changed, but ACL is not set for the directory.
I have a server running RHEL6 and a virtual machine also running RHEL6. I created a directory /home/data on the server and another on the VM. When I mount the host directory on the VM, I am not able to change the ownership/permissions through the VM no matter what. The ownership is set to "nobody" and I can't even change it to root.
View 4 Replies View Relatedmount an NFS directory as a regular user (which doesn't have sudo rights) because a suitable entry (i.e. with the user option) is defined in /etc/fstab file.But, when I mount it, I am not the owner of it! The owner is the default superuser of the system. So I don't have write permissions in the mounted directory.
View 4 Replies View RelatedI'm running Fedora 12 - Linux 2.6.32.21 with a boot partion on /dev/sdb3 of a hard disk.
I downloaded a vanilla kernel version 2.6.35.4 and have built it and run it successfully. I built this kernel to play with building device drivers.
My grub configuration uses the same root filesystem for my fedora installation as my vanilla 2.6.35.4 kernel; both use the LVM root filesystem. (/dev/sd4 /dev/sdb5 /dev/sdb6)
When I'm running fedora 12 (2.6.32.21) I can see the files in /boot which contains my kernel, system-map, initramfs, grub directory, etc. I also see my vanilla kernel 2.6.35.4 and it's associated support files (map, initramfs, etc.)
My question is when I boot into my vanilla 2.6.35.4 kernel and I look in /boot, I only see my vanilla kernel and it's associated support files. No grub, no fedora kernel. If I do a df -a, I see that /dev/sdb3 is not mounted like it is when I'm running my fedora kernel. I'm confused as to what is going on here. Can anyone shed some light on this?
I have a problem with sshfs. I want to share a binary with some others computers, but i only want them to be able to execute (no read/write ).

But when I mount directory using sshfs, users cant exec/read/write ...

I'm having trouble with an NFS mounted directory on a newly installed 5.3 server.
The directory mounts fine using this command:
However I cannot write to the directory despite it being mounted RW and having read-write access on the host (a Netapp Filer). If I check permissions on the mounted directory, I see it is owned by 'avahi-autoipd':
I have disabled the avahi-daemon in chkconfig, although it wasn't running to begin with. Any idea why this directory would be owned by avahi-autoipd and whether or not that has anything to do with why I can't write to the mounted directory?
I've looked everywhere and haven't found someone with a similar problem or even a hint to how to fix it or what's even going on.I'm trying to mount the Sims 3 raw ISO so I can install the game with PlayOnLinux. Every program or method I've used to mount it seems to mount it successfully. My problem is, that when I go to open the mounted ISO image, the folder is empty and nothing comes up. Even when I go to rightclick > Properties,it displays the contents as nothing.
View 9 Replies View RelatedI am using back in time to back up files from home and from another mounted directory on my system (ntfs). The back-ups are occurring automatically and appear to be complete; but, I cannot delete old back-up snapshots in the backintime GUI Also with sudo nautilus or as root in terminal with (rmdir) I cannot delete the snapshots. My drive is filling up and rather than uninstalling back in time, I would like to simply delete the unneeded snapshots. How can I delete these files? Is there an rsync file that I should configure to delete these? My expectation of backintime was that it would back-up at the requested frequency and not create complete duplicate copies of the files, but, use symbolic links to unchanged files. How can I verify if this is the case? Does the cron file control this>

I am trying to get a ubuntu machine (client) onto a windows active directory (domain) this i have done and you can login using winbind to the client desktop no problems however i dont want the domain users' home directories on the client machine so i have set up a ubuntu server (samba) to hold the home directories now so far i have been able to set up a share which both windows and linux can read and write to with no passwords needed, and if i have modified the /etc/fstab file on the client to mount the samba share on startup however if i login as a domain user it fails to create a home directory on the share with the following error:
"/mnt/home/admin2" does not exist
now the main question is this in fstab i have used a cred file stored in /usr/share/.smbcred which should be accessible by all users right? i know i can put the creds into the fstab file but i can't find how and it is just failing to mount when i try so if you know how i will try that, also does fstab run before or after the home directory is created as if it runs after then the cred file is working but the home directory is looking at a location which hasnt been mounted yet or if fstab runs before then the location is not mounting right (hoping for second one )

I have a server: A with some directory dirA/ I want to have an access to that directory on server B.
I was reading about "mount" but its very ambiguous for me.
I have a computer (C1) to which I can connect through the Internet (ssh, for instance) (it has a static ip and though it is sitting behind a router, the appropriate ports are all forwarded). I have another computer (C2) that doesn't have a fixed ip address and sits behind a router that I cannot fiddle with (so no port forwarding here). I would like to know if there is any way to connect from C2 to C1 such that a directory on C2 would be mounted on C1.

I have recently experienced a problem that occurred after an automatic update. After the update it said restart system. So I did and proceeded as normal. when after the reboot Firefox suddenly stopped working, crashed and upon clicking it again only a blank box appeared. Then my other apps followed and i soon couldn't do anything so i shut down my computer. Upon restart I got a black screen with tons of text and something around the lines of
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting / sys/ on root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or dirctory
[code]....
So I rebooted and pressed shift to open that grub thing and booted from an earlier kernel. This time it said checking HD for errors and after booted normally. Everything seemed fine but next day it did it again. Starting with Firefox crashing and then everything else. I again booted from a previous kernel and it worked but upon checking with uname -a it did not list the kernel i chose to boot from. So I decided to upgrade 10.04 to 10.10. This upgraded my kernel and deleted the old ones so i am hoping i am good now.

View 7 Replies View RelatedI've to make a Windows 2000 share on my Server Linux CentOS 5.1 with all the updates installed with yum. I've a directory on a Windows 2000 that contains some images for a catalogue. I have my internet site on CentOS 5.1 with a Apache - Mysql - PHP web server. I have to mount my directory on a share in /mnt/catalogueimages and made a symbolic link from my /var/www/html/mysite/catimages to this samba share.
This is what I do following your guide a this link: [URL]
I have placed in my /etc/fstab this line:
//SERVER/C/Catalogue /mnt/catalogueimages cifs user,username=Administrator,password=,uid=apache,gid=apache 0 0
My Windows 2000 server have no password.
After that I made the symbolic link:
ln -s /mnt/catalogueimages /var/www/html/mysite/catimages
All it's OK.
The problem is that I can't see the images via browser. I have tried also to put some images in the directory /mnt/catalogueimages, deleting the mount point, in order to see if the problem was in apache: the images are visible via browser. Why I don't reach to see the images mounted with samba?
I have attached a 2 TB LUN to the HP Blade Server running CentOS 5.3 via a Qlogic HBA. To provide the cluster users with sufficient storage areaa, I want to move only the home directory from the default partitioning schema to the attached storage and leave the remaining partitions on the main harddrive of the server. So, having copied user directories & files to the new location, i.e.,
/cluster/home2 on the new storage partition, what modification(s) should I make on the server?
/export/home is the default location for the users.
/cluster/home2 is NFS shared directory serving as the new home location for the users.

BusyBox v1.13.3 (Ubuntu 1:1.13.3.1ubuntu11) built-in shell (ash)(initramfs) After searching the Internet, I found a "solution". I just had to boot with a USB stick with the Ubuntu Rescue Remix (the normal Ubuntu USB won't boot either), and i wrote;
Code:
sudo fsck /dev/sdb5
Now I could start my Ubuntu again. So whats the problem? If I turn off my computer the normal way, there is no problem, but if I log off, put it into sleep mode, if something happens and I have to turn it off with the button it goes back to the first problem, and I have to reboot it with the USB stick and fix it all over again! If I don't have the USB stick with me, I probably wont be able to use my laptop!

I install both as letting Ubuntu decide partitions for one drive, do the same for the other, and create a raid, and do them from scratch. No dice, same problem.

I was looking for the specific shared folder. Instead I got a root level parent directory that included the folder I wanted, and a couple others.
smbclient -L <ipaddress> gives me a parent directory on the root
First question: Can I mount a specific folder within a share?
Second question: Could somebody define share? I thought it was the specific shared folder, but that doesn't seem to be the case.
