I have about 50 servers with at least 200 GB free on each host. I need close to 10 TB of continuous shared storage between almost half of the servers for a new app I building.
I was looking into buying a storage device but was wonder if I could get any use out of the free space on all the servers, grouping all of the free storage from the hosts into one reduduant storage array.
I have this unique situation, I think. My TV plays certain files only through external USB storage. My Ubuntu server stores all of these files on local hard disks. I do not want to buy an external hard disk and then keep moving it between both. Now, strange as it may sound, is it possible to somehow connect my server to the PC and expose a given local hard disk connected to the server, as an external USB drive to the TV?
View 1 Replies View RelatedI installed Ubuntu 10.10 (64 bit) on a Dell Precision 670 desktop that I share with another user. The OS is installed on a 160GB disk, which also has the /home folders. There is also a second internal disk (1TB) which has shared files (music, pictures, etc).
How can I configure Ubuntu such that either person can read or write to this shared disk? Right now, if someone is logged into the PC, the disk can be mounted, but then it is not available to the other person.
My Goal: I'm migrating data from the OpenSUSE server to the 2008 Storage Server. The idea is that all the data will reside on the 2008 Storage Server in an NFS share which will be mounted to the OpenSUSE server in the same location in which the data sat in initially.
I'd like this to be completely transparent to everyday use -- all programs designed to interact from a few other servers / computers will still work without modification, and, more importantly, all file permissions can remain the same. As far as I've seen the SMB mounting doesn't full preserve the *nix file permissions. I'm hoping the NFS mount will, but please tell me if I'm wrong. SMB is so much more straight-forward and already working. I should also note speed is a giant plus for NFS.
The Players:
Windows Server 2003 - The Active Directory server
Windows Storage Server 2008 - The new file server
OpenSUSE 10.3 - The workhorse server
I have no control over the operating system choice. I have no control over the AD server. I have limited, intermittent access to the person who does have full control of the AD server. I have full control over the file server and the workhorse server.
What I've done: The Storage Server is running Services for Network File System (NFS). It has a 6.5ish TB RAID partition configured for NFS and Samba/CIFS sharing which is used for the data storage. The Samba/CIFS share is mountable and accessible, but I haven't found a way to maintain proper user permissions on the files. When I connect the owner and group for every file is root:root, which led me to NFS in hopes this would fix the problem.
The AD server admin has installed Services for Unix, and we imported the OpenSUSE passwd and group file. Either this didn't work, or it take a bit more configuration. Tomorrow morning we're going to take a deeper look into the SFU configuration with the AD.
Right now I can mount the NFS share on the OpenSUSE under the root account:
Command results truncated to what I think is relevant info. Ask if you need more.
Code:
My Problems:
I'm hoping the "Permission denied" error is solely because the UID and GID mappings are incorrect. I have, however, tried to create an NFS share with full permissions to "Everyone" and anonymous access, and I get the same results.
Also I've run into another roadblock. Why do non-root accounts fail to execute the mount /mnt/datadir command?
Code:
AFAIK 1048 is not a restricted port, so regular users should have access to bind to the port. I also have a Gentoo machine where regular users are allowed to execute the command. The 'mount' command shows that the NFS share was mounted with the username executing the command too.
Server NFS Config:
Code:
The following are the settings on localhost
The above was written yesterday and not posted in hopes I could solve the problem this morning. I failed.
Update: The domain admin installed an NIS server on the AD server. I installed an NIS server on a Gentoo Linux box. They weren't able to communicate. The Linux box thought the Windows NIS service wasn't running and Windows couldn't find the Linux machine. NIS led to a dead-end right about there. I also tried to manually link the user accounts to UNIX UIDs via the AD user properties window to no avail.
For use on a test LAN, ie. security is not an issue, I need to install the most basic FTP server available just so we can share files back and forth between test hosts : launch FTPd, have it share a directory through either "anonymous" or a single, shared login/password?

View 4 Replies View RelatedI have an external drive that I want to do backups to. Most times it goes great, other times the server gets real sloggy, and I do a 'df' and see I'm at 96% disk usage. What has occured is the disk failed to mount apparently, so the backup backs up to my local disk at /media/backups/
I have /media/backups in my /etc/fstab pointing to /dev/sdc1, but I think the external disk will sleep when not in use for long periods.
How do I make sure /media/backups is REALLY going to the external drive and not my local drive? Is there anyway to sort of test it BEFORE I write umpteen gigs to my local hard drive?

After installing the latest updates to 10.04 (there were many, so I don't know root cause) Flash didn't work properly. I'm running Adobe flash 10.1r53, 2.6.32-22-generic kernel, Chrome5.0.375.86, Firefox3.6.3
Pandora complained "Flash Local Storage is Currently Disabled". When I went to Adobe Flash Player Settings Manager Global Security Settings Panel, it wouldn't allow me to click the box to "Allow third-party Flash content to store data on your computer". It was unclickable. I also received the Google Chrome error "Your Permissions Can Not Be Read".

The fix to Flash isn't much different. Perform this command & it should fix it for Google Chrome and Firefox.

Problem:Your company network has internal only hosts / websites with names that end in .local, e.g.Your freshly installed Ubuntu machine works fine on the network, has internet access, etc. but cannot connect to these particular systems.Testing DNS with tools like dig / nslookup works fine, but normal name resolution with ping / telnet / browsers does not work.Solution:1.

Press Ctrl-X, Y, Enter to saveExplanation:Ubuntu ships configured to do name lookups for self-configuring networks, based on the AppleTalk / mDNS / Bonjour protocol. In the configuration shipped for the resolver, this protocol is considered the final aurhority for the ".local" top level domain, and DNS will not be checked. The above configuration change eliminates this and restricts lookups to (a) /etc/hosts file, followed by (b) DNS
View 1 Replies View RelatedI can reach other hosts by means of their global addresses by either the IP address or hostname (that has the global address). What I want to (also) do is have a hostname that references the IPv6 link local IP address (an AAAA record in DNS, or just the fe80::<whatever> address in /etc/hosts) and use that host name in commands to access that host. The problem is, an interface ID is needed when making such a reference.
It sure looks like the programs just pass the host name string on to the resolver library, which does not understand the significance of the '%' even though it could find and see that the name preceding the '%' is consistent with that being an IPv6 link local address (e.g. the logic could have been "split at first % and see if preceeding name is found as a link local address and accept that if so, or ignore the split otherwise" ... but it isn't). Is there a different syntax for this ... or was it overlooked in the design of programming around IPv6?I want to be able to address a host by its link local address, while still using a mnemonic instead of having to type the IPv6 address.
I have one scsi storage array, JetStor SATA 416S,split into 2 halves. each is RAID5 12TB. Is it possible to dedicate each half to a different rhel5 server. I have "lsi22320-r" ultra230 dual channel scsi adapter in each server.
The first server sees the 2 halfs however the second server doesn't on the first server:
I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.
It is running Ubuntu server 8.10
The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.
My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.
I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

Is there a "correct" way to set up a shared folder between two local users using only EXT4 that will allow both users read & write access to everything in the folder?
Here's my scenario: My wife and I use the same computer. I want two separate user accounts (mine and hers), but I want ~/Music to point to the same location for both users so that I don't have to duplicate all of the files.
Too protect the innocent, I'll use Jack and Jill.
So say Jack downloads or rips an album:
"/home/jack/Music/Radiohead/Ok Computer"
I want Jill to be able to able to create a folder:
"/home/jill/Music/Radiohead/Hail To The Theif"
I know the basics of symlinks so I can get /home/jack/Music and /home/jill/Music to point to the same place. I also have Jack & Jill in the same group.
The problem I'm having with my test setup is when Jack creates "/home/jack/Radiohead", it is set up to where Jill can read, but not write. So she can play songs from Ok Computer, but if she wants to download Kid A, she has to go in and manually change the permissions on Radiohead first.
Also, while I might set up multiple directories this way, what I DON'T want is for Jack to be able to modify /home/jill/otherdir where otherdir is just a regular directory set up with default permissions.
Oh, and as an added bonus, it would be nice to set up another account (i.e. a "guest") with limited permissions that can read, but not write/modify.
