CentOS 5 Server :: NFS Mount Of Loop Mounted ISO's Showing No Files
Jul 16, 2009
I'm having a problem accessing files via nfs where an iso has been mounted through the loop device on the nfs server. Basically what I am attempting to do is access the 6 CentOS 5.2 ISO's via NFS from one of my client machines. The client is able to mount the share and see its sub directories leading up to the mount point of the ISO, but the contents of the mounted ISO image are simply not visible (on the client, they are visible on the server).
I am running FTP server using vsftpd 2.0.5-12 on Centos 5.3 64bit with default settings, annonymous access enabled. Each night new files are created and moved into a FTP subdirectory (/var/ftp/spectra) by a script. The files are owned by a local user/group, not root, and the same holds for the /var/ftp/spectra subdirectory. The new files are not visible via FTP. Only visible are files that were created the same day when I made the directory /var/ftp/spectra. Also files that are created "in place", e.g. by vi, are visible until I change their owner/group. This is the situation when vsftpd is runned as a system service (/etc/init.d/vsftpd start).
When I start the vsftpd directly using the command /usr/sbin/vsftpd (both without or with the configuration file specified), all files are visible and normally accessible via FTP.
I'm trying to mount a mounted NFS share. I have a server that connects through VPN to a network, that has the NFS share exported. I am able to successfully mount the NFS share on that server, in /media/iSCSI. Now I want to share this NFS share with other servers, that are on the same network as the VPN-ed server, but are not connected to VPN. When I try to export the mounted share, I get:
I've recently started using Linux Mint (version 10) on a Dell Mini 1012 netbook. I'm using a loop device to mount a file on a NAS but whenever this loop device is mounted and has been accessed, my machine fails to shutdown.
Firstly I mount a share on the NAS using cifs (the NAS is aimed at Windows machines so doesn't support NFS). I have a sparse file on the share (which I created using Cygwin in Windows, using the dd command).
I used losetup to create a loop device and formatted it as reiserfs.This works and I can successfully use the mount point. I'm using it with Backintime.If I try to shutdown my machine without unmounting the loop device, shutdown hangs.
These messages just keep repeating and the system never shuts down.So I assume the problem is something to do with unmounting the CIFS/loop device.If I unmount the loop device all is fine. I don't need to unmount the cifs share.Any ideas on how to resolve? Should I add a script to run during shutdown (i.e linked from /etc/rc0.d and /etc/rc6.d) to sync and unmount the loop device? Or is there a better solution?
I would like to know when usb inserted, its showing cant mount when i clicked details its showing bad blocks in beginning , and smething in /dev/sd6. Can i knw why usb drive cant be mounted automatically , even if its set to do so, and to cope the error mentioned above
Just moved to Ubuntu from XP. Whole process has gone very smoothly, but left with a small problem (i.e. it isn't actually affecting usability) that I don't seem to be able to fix and can't find on forums/internet. I also have a problem with the Floppy drive, but I've seen that problem elsewhere in the forums.
It's a dual boot system with both NTFS and Ext4 drives. All are visible and fully accessible. I decided to convert one of the NTFS drive to Ext4. That appeared to be successful and was successfully remounted as an Ext4 drive. The drive label is "Data". I did have a bit of a problem getting it remounted so that I could see/use it under my log-in as opposed to just under root. It's at this point I think that I did something to create the problem.
I now have two entries for "Data" in drop down menu for Places. The true one is shown as a standard hard drive icon, but the false one is shown as a different icon - possibly an external drive icon (note that the floppy drive is also showing as the same icon and I can't access that, but I've seen that's a problem elsewhere in the forums).
I can write and read to the true "Data" hard drive. If I click on the other false "Data" icon, I get the message "mount: /dev/sdd1 already mounted or /media/Data busy mount: according to mtab, /dev/sdd1 is already mounted on /media/Data". If unmount the true drive and try to mount the false drive, the system mounts the true drive instead. If I log into nautilus as root, neither the false data drive or the floppy appear in the left hand panel.
I thought anything mounted to /media would appear on the desktop?mount /dev/sdb1 /media/datadoes mount sdb1... files are available in Terminal. But there is no icon on the desktop. Why? What do I need to do to get a desktop icon?
I have recently installed Fedora F11 with a Samba server. The smb.conf seems fine but I cannot see any of the files in the share from a Windows machine. I am probably missing something unbelievably simple but driving me nuts!
I can see the machine and share from windows
When logged in as the user fred I can see all the files in Linux - most are owed by fred.
smbuser: Code: # x_name = SMB_name1 SMB_name2 ... root = administrator admin nobody = guest pcguest smbguest fred = fred smb.conf: Code: [global] workgroup = Workgroup server string = Samba Server Version %v
netbios name = MachineName
hosts allow = 127. 192.168.0. ......... [Docs] comment = Main Documents path = /mnt/documents read only = no browseable = yes valid users = fred ......... The other thing I find a bit odd is that Code: service smb restart does not effect the way that the windows machine sees Samba. It appears that you need a full restart to get the changes to show properly.
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.
For some strange reason, my media mounted in /media is not showing on my desktop on Lucid (10.04).I've been through gconf-editor to make sure the box is checked to show the mounted media in Nautilus. I also checked the options to show my Home folder and Computer icons on the desktop, but these do not show either.Tried ubuntu-tweaks to see if it would work, but no go there either.
I have two external hard drives mounted to my computer. They both work and are accessible. The one shows up on my desktop when it is mounted just fine. The other one does not. I went in to Configuration editor-apps-nautilus-desktop and checked the volumes_visible. That makes the other one not visible/visible but not the one I am having problems with. I read somewhere that devices must be named for it to show up and both devices are named, I even changed the name and that didn't do anything. Again, this device shows up in my computer but not on my desktop like all my other devices do. If anyone has any ideas on how I can get this external hard drive to show up.
This is probably me looking but not seeing an option somewhere. I re-installed 10.10 over 10.04 by formatting the root partition but keeping the home partition the same, to save me a lot of work. (64 bit) However, now when I mount a CD, DVD or USB stick, they don't appear in Dophin's "Places" window. What have I missed please?
I recently moved into a new place and when I hooked up my webserver, I wasn't able to bring up my page, even from localhost. With some digging, it seems that I can't access the database that housed my posts (wordpress installation). I looked for the datadir in MySQL and that directory shows the wordpress directory that should be holding the database and all the files are still there. 1) why the database no longer shows up 2) how to restore the database from the files?
I have a bit unusual request. There are three partitions on my hard drive. Two of them were assigned to mount points / and /home during system installation. The third one was left intact. After installation the first two partitions were automatically integrated into directory tree and there was a shortcut on the Nautilus sidebar for the third one. Then, I registered the third partition in /etc/fstab for automounting at /home/user/Data directory. For now it works fine, the volume is mounted on startup. But I still have the shortcut to this volume in Nautilus sidebar and icon on my Desktop. I am interested, if it is possible to disable showing of this items on Desktop and in Nautilus to make the third partition look like registered at system setup time.
Summary of issue: EXT4 filesystem won't mount--with error = mount: unknown filesystem type 'ext4'. Is no ext4 in kernel the issue? Or is something corrupted?Really perplexed by this. I updated Centos 5.5 to 5.6 to get ext4 (5.6 is supposed to have full support of ext4). I built several arrays and put the ext4 filesystem on them. All went well until I tried to mount them. BTW, this array (below) is set up as a RAID6 using partition 1 of #8 2TB drives.Bear with me here; just trying to be complete and not waste your time.
Attempting to mount give this:[root]# mount -v /dev/md1 /asc/array1mount: unknown filesystem type 'ext4'Note: it does "fake" mount with ption (which apparently does everything except the system call):[root]# mount -f -v /dev/md1/dev/md1 on /asc/array1 type ext4 (rw,grpquota,usrquote)e2fsprogs:Package e2fsprogs-1.39-23.el5_5.1.x86_64 already installed and latest version (for Centos 5.6; CentOS 6x uses the 1.41...)
I have a large NFS share with a variety of software ISOs on it. I've only tried this on Red Hat Enterprise Linux, but when trying to do the following, the mount comes back with an error indicating no permissions to mount. Why would this be happening?NFS is mounted thusly:mediaserver:path/to/isos /media/nfsThis is the mount call that failsmount -o loop /media/nfs/product.iso /tmp/productIf I copy the ISO, there is no issue. The NFS share is mounted rw.How can I loop mount the ISO from the NFS share without copying it first?
i have been trying to complete the following project1) Configure a FTP server where we can upload and download files.........2) server must run at 9 pm & stop at 9 am automatically ............although the first task was easy ,i have no idea how to accomplish the 2nd task(not to mention I'm a new user)
I had a centos Linux 64bit installed on my server. Unfortunately I don't know how but my OS crashed and now I have no way to get back my DATA except for rescue disk. I have a Linux 64bit loaded in my server with rescue but I have tried many ways to mount my hdd in Linux and was not succeed.
I have been having the hardest time with this. I am trying to mount a share on a Ubuntu 10.04 system from another Ubuntu 10.04 system.
The system with the share has the OS on one drive and then data on a second internal sata drive that is mounted. The share is on this second drive.
I can see it when I browse networking from the other system but it won't mount. I get a message saying that the folder contents can't be displayed. I do not have permissions necessary to view the contents...
I have tried setting the share folder permissions as permissive as possible but can't get passed it.
I setup my client to mount some nfs mounts at boot but although they seem to be mounted, they are not! Before I give the details, I'll start by saying this is not a wifi problem. I'm using a good old wired connection. The server runs NFS3 with the following line in '/etc/exports':
I have tried the following nfs options in the fstab as you might have noted above: _netdev,auto,bg,retry=10. None of them seem to fix the problem. I realise a quick hack at boot time would fix this in an instant but I'd like to figure out why this is failing.
I have two servers, 82 and 70.My exports file on 82 reads /...70(rw)on 70 I have a mountpoint called mnt_for_82I execute on 70mount -t nfs -o rw ...82:/ mnt_for_82I go to server 70 and indeed can read and travers the mounted subdirectories. However, I try to create a file or subdirectory under the mount point on 70 and I get a *Permission Denied* error.I'm sure there is a simple explanation for this issue as well as a correct nomenclature for what I'm trying to do in nfs
I need to know particular mount point mounted or not before send data to that mount point.Are there any commandsi used this command. mount -t nfs 172.16.102.50:/root/ESSR_share /root/shared_storage/pc50 -o rw,hard,intr but it take long time (when machine(172.16.102.50) is not available)
I need to read information from SUN hard disks which are about a decade old. My CentOS 5.6 mount command comes from util-linux 2.13-pre7."mount -t ufs -o ufstype=sun /dev/sdb2 /New" reports "mount: unknown filesystem type 'ufs'", though its man page describes such settings.How could I read an external UltraSCSI hard disk (yes: high pitch noise and only 9 GB capacity) on a current CentOS? Is that possible at all?
I dont know if this is possible or not but here what I would like to do. I have 6 linux server and each has 100GB disk space. All of these 6 box are compute nodes and space are not used really. However, If I can combine 6 servershard disk that will in total 6*100GB gives you quite a bigger space. Is there any tool or ways to mount these drive in one volume instead of mounting individually ?
