I have an exported (via NFS) file system that contains other sub-mounted file systems (eg, DVD drives, ISO files, etc). While the sub-mounts show up locally, they aren't visible when the parent mount is exported.
In /etc/exportfs, the nohide option is specified for that export.
What else do I need to do?
I have a filesystem mount at /A. I can export that filesystem via nfs with no issues.
I then mount an ISO image in a folder under /A: mount -o loop fname.ISO /A/isomnt. The original mount /A had the nohide option.
The files in the ISO image are available on the local machine, but the submount doesn't get exported by nfs to any other systems (FWIW: it does show up via samba). I have even run exportfs -a after the ISO mount, but that did nothing.
I have several ISO files that I would like to make available this way, without having to make several nfs exports for all of these, and then make mount commands on all of the remote systems.
Is this possible? If so, what do I need to do to make this work?
I am using OpenSuSE 11.3 (64 bit) and am trying to force my new server use NFSv4. Later, GSSAPI, sould be added, but for beginning, I want to configure without it for now. If I try using NFSv3, this works good, but I need NFSv4. I have exported my directory:
Code:
omega:/ # cat /etc/exports
/distrib *(ro,no_root_squash,sync,no_subtree_check)
After mount attempt I have a error:

View 2 Replies View RelatedI had everything working okay, but suddenly I couldn't mount an NFS share from one specific machine to another specific machineIn detail, I have a server (machine 'S') with a share '/big' exported. All hosts on the subnet (ie, 192.168.1.0/24) have rw access . A client machine, 'A', can mount the share S:/big. But client machine 'B' cannot. Not only are they on the same subnet, but this had been working for quite awhile. Also, I have another client 'C' and it can still mount the server's S:/big share.
When I say that 'B' cannot mount S:/big, what really happens is that the mount call just hangs for a long time (10min+). There is nothing in dmesg or /var/log/messages either.I don't think I did anything that would have changed this. The lines in '/etc/exports' are still the same. Machine 'B' has complete net access to 'S' (ping, ssh, etc), and 'B' can even mount samba shares on 'S'. Just not nfs.
I have upgraded one of the computers on my network to Fedora 14 (previously Mandriva 2010.1). There's a directory on another machine that I want to mount on this one. The directory can be mounted OK on two other machines in the network (including one running Fedora 13) and, before the upgrade could be mounted on this one, so the nfs server is OK.
If I try to mount manually I get the following:

/etc/hosts has the names and ip addresses of all the machines on the network so the reverse dns lookup (which I have fallen foul of in past years) shouldn't be an issue. So I'm kind of out of ideas. I don't recall there being any problem accessing this mount with Fedora 13 .
I am trying to mount /NFS as nfs mountpoint on two servers ( A & B ) having OS OEL 5.

I have a machine which had a hardware fault and I want to read the disks by plugging them into a SATA-USB docking station in another machineWhen I do thisI can see the partitions on the old disk, but cannot read the LVM volumes on one of these physical partitions.Commands like pvscan do not find anything on this disk. Apparently you are supposed to export the volumes before trying to read them on a new system, but this was not performed. Does anyone know how to access the data on this disk? Surely it is possible.

After making several attempt I cannot mount share on client. What I am missing here? OR is there problem with F11 with NFS server? While throwing everything including sink... I ran tcpdump on server while issuing mount command from client; I got following tcp dump.

I have two mount points that used to work. I have them defined as cifs shares in fstab, and they map to a Windows machine, which I am able to ping from my Fedora machine, but for some reason I get a mount error 2, and the destination is not accessible. The man page doesn't really give any troubleshooting steps. Since I am mounting by IP address (which as I said has worked before), nothing has changed, although the IP address did change, which I updated in the fstab file to the new IP address (and since I have reserved this new IP address so it can't change again!)
I ran a test and shared a folder from another one of my computers, and added a line in fstab to auto-mount that, and I get a "permission denied" error 13, which is different than the error 2 I get on the other 2 shares. What should I be looking for as far as actual connectivity between the machines? I have verified that the windows machine is on and I can access the same shares from another computer.
Update: Added the host and IP address to my hosts file, and replaced the IP address with the name, and still get the same error. Also, the share name has a space in it, so I replace that with a "�40" space character (which worked in the past). I tried replacing that with an actual space, and putting quotes around the URL, but then I get a "bad URL" error.

I have just been gifted with a Linux dedicated server for the next six months, with an option to renew after that time has expired, and I'd like to set it up for FTP/P2P use. I do have some familiarity with Fedora from work, but only as a pre-installed desktop OS. The company providing the server has asked me to choose a OS, so of course I picked the one with which I already have some knowledge. They've also asked me to provide partition and mount point information, and it's here that I'm having some problems. I've spent most of my free time today reading everything I could about partitioning for a server, and I'm still not comfortable making this decision on my own.
The server comes with two drives - one 500GB and one 1TB, and 8GB RAM. My thinking is to use the 500GB drive for the OS, and the 1TB for media storage. I know I still have a good bit of learning to do, but I just want to get the blasted thing set up so I can get on with the hands-on part of figuring out how it works.
I'm using a simple Bash script to export an environment variable, eg.
Code:
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/my/own/dir

So after much intense reading of linux documentation and posts I can't find an answer to my question. Maybe someone can help.I am trying to access a kernel symbol that isn't exported (the symbol exists in /proc/kallsyms but not in Modules.symvers). Is there a non intrusive way (by avoiding compiling the kernel with CONFIG_KALLSYMS and parsing /proc/kallsyms in my LKM) to reference kernel symbols that are in /proc/kallsyms and not in Modules.symvers i.e. not exported symbols.

Both machines are running FC11 - should i be using nfs4?
I export a folder via NFS service.I able to mount this NFS share in another Linux machine.The folder has many files.The ownership of these files aren't belong to single user. There are more than 10 different users' files in the folder.I am trying to migrate all these files to another folder. When I use "cp -a", the new files' ownership are all reset to the logon user.
Both NFS server and client machine has exactly same copy of users/groups as these 2 machines refer to same LDAP directory service. When use "ls -al" to list the NFS share in client, I can see the files ownership is exactly the same as the NFS server.Is that possible to preserve the ownership of files while doing such migration? The "cp -a" fail to deliver the job.
I run a headless Ubuntu 8.04 server, which acts as a web, email and file server. I am sticking with 8.04 as it is a LTS release and will upgrade to the next LTS when it is released.
I have two external USB drives, that I need to mount at boot. I have been using /etc/fstab up until now, with the following entries:
Code:
However, as I gather from doing searches is quite common, occasionally I get an error during boot (causing the system to drop to a recovery shell) because the USB drives take time to wake up and the system hasn't found them by the time it reads /etc/fstab.
From doing searches, it seems there is nothing you can do to fstab to fix this, so you need to mount them using an rc.local script instead, using:
Code:
The problem is, as I have two USB drives, their /dev/sdxx location changes between boots. I thus want to use UUID codes as I do in fstab, however I haven't found anything about this.
Does anyone know how I can use the mount command and UUID to mount a drive in rc.local and what options I have to use the mount the drive with the same options that I am using in my fstab entry? Obvisouly, I can't refer back to fstab using the mount command, because then I will still get the boot error issue if they are listed in fstab. And there is no space internally for the USB drives as there is already two internal drives.

Yet, when I type mount all it reports is (rw,mand). The share works just fine, and I can see the masking (all files are showing as rwxrwxrwx as expected etc) but mount is not listing the options?!
Is this normal expected behavior? Is there a bug report on this? I've google'd to the best of my capabilities and could not locate any such information which is why I decided to hit the forums prior to filing a bug.

I installed bacula as i beleive it will do the job (unless someone has a better and simpler to configure idea) and i would like it to backup to my external usb 1Tb hard drive. I am able to mount the drive manually but this server gets turn on and off often to save power (and cut the electric bill) when not in use. I tried adding a line to fstab but when a do that, the server gets stuck on the startup even with the drive turned on. I read somewhere that i should use the UUID of the drive as it could change from sbd1 to sbh1 on restart so i did, same result.

View 6 Replies View RelatedI am very new to Ubuntu and have been having trouble mounting my FreeNAS drive. I installed Ubuntu 10.10 on partition sda2. I wanted to keep FreeNAS completely separate from here, so I used Virtualbox to host FreeNAS as a guest o/s on a second hdd, sdb1 mounted at /media/NAS-Data. I can access the NAS from all computers except my Ubuntu box. I have CIFS/SMB and NFS (among other) services enabled on FreeNAS.
I would like to run a program that needs access my music. I followed many of the "How To's" on the forum, but am not sure if they didn't work or if my setup is different and can't work the way that has been described. My last effort was to mount the file system using NFS, but I get a timed out error.
When I run showmount -e 192.168.0.44, result is /mnt/cNb-NAS-data 192.168.0.0. I've tried many variations to mount, but none have worked. For all I know, again I'm very new to Ubuntu, the file system is already considered mounted (/media/NAS-Data), and I just need to find the correct path to access my data. This is probably obvious, but when I navigate to NAS-Data, it has the Virtualbox NAS.vdi file.
Was hoping someone might be able to either help me get the correct path name or mounting instructions in order to view these files from Ubuntu.
