Is it possible to present multiple LUNs from 1 SAN with 1 NFS server? Currently, my NFS server is directly connected to my FC SAN. Do I have to install and configure multipathing for this to work OR is this just not possible to do over one connection?

View 1 Replies View RelatedI'm trying to build a custom setup that requires a flash drive and a CD to both be mounted to root. Applications, boot data, and other static directories are on the CD, while /home, /opt, and /tmp are on the flash drive. Is there a special option I can enter into fstab to allow this? If not, I intend to modify my kernel to allow this, but I'll need to find the sources that control this function.

I made it with dd by copying it off my USB stick. e.g. "sudo dd if=/dev/sdb1 of=./image.ext2" I can mount said image with the command: "sudo mount -t ext2 -o loop ./image.ext2 /mnt/" Now, say instead of copying a partition with dd, I copy a whole drive. e.g. "sudo dd if=/dev/sdb of=./image.img". sdb had 2 partitions on it. How can I mount those separate partitions without copying that image back onto the USB drive?
View 1 Replies View RelatedI setup samba file sharing to auto mount in fstab. Everything works great except when a computer has more than on user account.
The folders in mnt are owned by root and ownership changes to the first user account no matter what user logs in. So only the first user can edit files in the mounted share.
Anyone got a clue why this is happening? Seems the mount folders should be changing ownership to the user that is logged in.
I'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails
* Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.

I have an XFS filesystem (not my root filesystem) that is not mounting.
We had a power failure over the weekend. All but one of our XFS mounts is comming up. Its a large mount (2TB) and I am not seeing errors per se...
But after attempting to mount it, it has been 4 hours and all we see in either dmesg output or in the messages file from the kernel is:
Our mount process is dead and I don't see any disk i/o going on. Am I missing something here on this?
I rebooted the box once earlier and was able mount read-only with norecovery...
I tried xfs_check and it also produced a dead "xfs_df -i -p xfs_check -c check /dev/sdd1"
I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code:
sudo tcpdump -i vlan4 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

In my production setup, i have 3 servers using the same mount point. However, i see that the IOPS is low. Does this kind of architecture have any impact on IOPS. In case it is neutral, how can i tune my setup for better IOPS.

View 2 Replies View RelatedI have an issue with users logging into a server. There are multiple (5 or so) database admins that have to log into a windows 2003 server and from there log into a red hat server. Once they are in the rhel box they execute an app (let's say xclock) that gives them an xwindows session on their desktop. Currently only one person can do this at a time, but they have asked me to configure it to allow multiple users to log into the red hat box from the windows server and run an xwindow.

It's work very well until i try restart my client server and the mount from 192.168.2.83 is gone, if i want it work again i must run mount script again. Can it become the permanent mount, so when i restart my server the mount is already exist?
- we have a bunch of linux servers.
- lots of users work with linux Desktops. They use them as testing servers.
- All the infrastructure has the Authentication services linked by Quest Auth Services againts an AD. This gives us the option of logon scripts, startup scripts, and other things.
- One interesting option this Quest thing gives us is SUDO management. We can edit sudoers file by GPO politics.
- Now we are deploying a NAS server from Hitachi with cifs and NFS mapping capabilities.
- Servers are managed by IT, so nobody can go root except us.
- Desktop users will also mount the NFS shares so they will be able to work with real data and read their own data from servers.
- Desktop users can go sudo su.
- If desktop users go from root to another user, the NFS let them work as they where the other user.
I would like to keep them from swithching users, but only between AD users, they must be able to switch to apache user or postgres user.
I want to be able to mount an ftp account to a local folder, I have set up a ftp server that is working fine, I have tested it with a few windows ftp clients and it works fine. I am trying to use CurlFtpFS to mount it to /backup as I know it is supported but am running into an error I cant get around. I have tested that my box can access the server using the ftp command, see below
Code:
root@Fileserver:/# ftp 192.168.1.254
Connected to 192.168.1.254.

I'm trying to build cluster computer system using redhat linux enterprise 5.5. And I'm on the step to set up the NFS mounting. (step 3 of part VI on this paper: However, I kept getting "permission denied" when I used the command "mount -t" to mount the slave node onto the hard drive of the master node. Even when I edited /etc/fstab file to make it automatically set up during booting, I still receive the same result. By the way, I've already logged in as a root user on both slave and master nodes.

Just the last day or so, I've noticed a long pause when I boot my laptop, with lots of disk activity. dmesg says:
[Code]...
Why would there be a 15-second pause (during which the disk is slammed) between mounting root and mounting swap? During this time I see nothing but a blank purple screen, there are no cycling dots or text scroll. Is this normal and I'm just freaking out over nothing because there's no indicator of progress?

I am having permissions errors every time I try to mount a windows host. I have a linux server and all the windows computers can see that computer and its files, but we wanted to start backing up the linux machine to one of our other computers. so I tried to mount one of the computers. here is the sequence of events:
Code:
$mount -t cifs //192.168.1.194/Admin$ /mnt/Anita-comp
password: (I have no password so I left it blank)
Mount error (13): Permission Denied
I tried all sorts of passwords we use around the office and none of them worked.
I then decided to try mounting one of our other computers. this one looked like it worked fine. no error messages at all. (I left password blank) so I look in my filesystem and the mounted drive is not in the /mnt/Anita-comp file. What gives?
My question is that I have a handful of servers, Server 1 is a Suse Linux machine and Server 2 is a Windows Server 2003 machine. I can mount and access the files/shares on the Linux machine no problem but when I come to using the Server 2003 shares I encounter problems ... here is a snip of my fstab ...
Code:
//10.0.0.20/applications /myfolder/applications cifs username=user1,password=pass1,auto,uid=user2,gid=group2,0 0
user1 and pass1 is the username and password of a user (local to the remote machine) and user2 and group2 are taken from the machine performing the mount.
Am I doing it right, is that how I should be mounting a share from a (Domain enabled) Windows Server 2003?
