General :: Find Out Server Is Connected To SAN Storage?
Apr 10, 2011We have near about 90 RHEL servers. I want to find out which servers are connected to SAN [HP-SAN] storage???? Because many of them are having local hard disks.

View 2 RepliesJust installed ubuntu 10.04 on my Dell inspiron 1525 laptop. Everything got installed right, and I elected to select the sta driver rather than the B43 driver. After restarting, the b43 option disappeared. The wireless said it connected, but when i went to firefox it wouldn't load and said server not found. My wireless card is a bcm4312. Any ideas as to why this is not working?

USB storage devices are painfully slow, if the data to be copied is above 4GB it works on transferring for more than half an hour and then comes up with an error dialog(saying something like file size is too big).

There will aswell other features i was planning to use on it which made me think of linux, for example, svn server, websever with mysql to testing my applications, connection manager, all these i am sure on how to make and setup... but i am not very familiar with samba hence i am not sure if it is the best options for file sharing aswell as media sharing and/or my only option.i also heard that ntfs might be trouble some for linux in some cases

I would like to know if it is safe to clear it and how to clear it (assuming it will not disrupt/kill server services to do so).
I have Matrix control panel so i can view the storage etc but it does not have an way of clearing the /Var directory.
I have Putty Access to root but do not know which command to use.
I found a few threads but the information is not clear to me as there seems to be an assumption of basic knowledge I don't yet have.
My linux/ubuntu support that usually does this kind of thing for me is away and not contactable and my server is grinding to a halt and unable to store/send email.

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...
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.

My system is SUSE 11.1 I want to see who is connected via SSH. For instance, I have users connected using FileZilla. I can see in th e/etc/var/messages that they authenticated/connected, but I can't see if they have since disconnected or not.
Also, about 3 years ago I used to use Fedora for my SSH and in the sshd_config I'd make custom logs for each account, specify which user accounts were possible, port number, etc, etc. Is this possible to do using the SUSE linux? Any links on how to do this on suse? I haven't used linux in 3 years and can't find my old sshd_config files to take a glance...I did look at the sshd_config on SUSE, but it looks very different.
The intention is to have this system dual-boot. When i first put it together, i decided to setup a raid5 array spanning 3 sata drives. I installed Windows 7 first, decided i'd get to Linux later. I left 150mb or so at the beginning of the array for /boot, and about 200gb at the end for my linux install. i'm getting to the linux install. My distro of choice is Fedora 12. I start the setup, and at the point where it's time to partition, the installer tells me that its unable to find any suitable storage devices.
I Crtl-Alt-F2 to a console, and fdisk -l. Fdisk reports three individual drives which all have partitions already. All have free space. None make sense. So i turned to google, and found some threads which explain that this chip doesn't run a true raid, rather its what's been referred to as fake raid. Which is that it depends on the windows driver in order to actually present the array to the OS, and that the best way to get by that on linux, is to break the array, and use LVM instead.
That's all well and good, but i lose two things in doing that. First i lose the resiliency of raid 5, and second, well, what does that do to my windows install? I've considered moving all of my data from windows to other machines, and then just starting from scratch, but i'd really much prefer a method of using the chips fake raid in linux. Is there a driver, or module which i can install to make this happen?
I have a computer with grub installed, and nothing else. I'd like to install Debian on it without having to burn a CD. (and I don't have any flash disks.) It has a nice ethernet card, and I have another computer right next to it with an ethernet card. I also have an ethernet cable. However, I don't have any router free which I can mess with for these purposes. As I've looked up, apparently modern Ethernet cards don't need crossover cables, normal cables will work for this type of connection.
I've tried several different "tutorials" on how to set up a netboot server, but
None of them are complete. All of them assume that you understand how DHCP works, and that you can do things like set up a dnsmasq server. I don't understand the DHCP protocol, with submasks and whatnot (I know that it is the protocol for assigning computer network addresses, and that's it), and I don't think I should have to in order to simply connect two computers. All of the tutorials give you incomplete configuration files, and ask you to fill in things which I don't understand, and for me it doesn't make sense to customize these settings, as I just want to connect them and I really don't care what ip address the TFTP server has or whatnot. All of these assume that you are going through a router. I am not. When I try googling for ways to directly connect two linux computers with an ethernet cable, I can't even find instructions, just more references to "you need crossover cables".
So basically, I have two computers directly connected by ethernet cables. Tell me what packages I need to install, what the contents of my configuration files should look like, and what, if any, commands I need to run in order that when I turn on my second computer, and select network boot, it will start up a minimal debian system.
EDIT: Hmmm, it looks like I actually have a linux kernel installed too, but no root filesystem (so no other programs besides busybox).
I have 2 servers each one with a RAID and I want them mirror they data so if one of them goes down the other one take the job with out disruption. I've heard of multipath by I want to know it in detail or learn of more options.
View 2 Replies View RelatedWhat is the current state of NFS failover (i.e. setting up two server with shared storage, with automatic failover if one fails?) I've seen a cookbook, but no details that would let me assess how well it works. There are lots of complex issues with data consistency, but the detailed information on that is years old. Our needs are fairly simple: 2 servers, a shared array, and I'm reasonably sure that we don't use locking. However we'd like failover to work reliably without loss of data.

how both storage devices will be supported by Ubuntu or Debian??

View 3 Replies View RelatedI just installed Ubuntu 10.04, 32 bit, yesterday on my Dell Latitude 6500E and I am new to Linux. I can't find my HP LaserJet 3015 on my home network, even though it is connected to a new Windows 7, 64 bit PC thru USB. The other Windows PCs find it fine, and all 4 PCs can see each other on the network. So, I installed the HP software (http://hplipopensource.com/hplip-web...all/index.html) and that went smoothly, but the printer is still invisible. I also added Samba and that works great like everything else. I plugged the printer in directly to my Ubuntu laptop's USB port and it printed instantly. Now, if I could just print to the LaserJet on the network. Anybody got this one figured out? Does Wine provide a way around this?

The storage device is a gfs partition mounted on the servers as the home directory using SAS cables. These servers have RHEL 5.4 as the installed operating system.
Setup2: A standard tower server with Debian 6 as the operating system used for tape backups. This has a tape drive connected to it.
Question: How to mount the storage device of setup1 using NFS on the server in setup2.
I need a bash script to run ARPON for the connected network device, eth1 or eth2. (ethernet or wireless)
Arpon has an option (-o) to select the network automatically, but it only works for ethernet, hence i need this script. I've also tried running arpon for ethernet and wireless at the same time, but the arpon process running the inactive device will consume all of my CPU.
So, basically i need a script to find which device is connected, eth1 or eth2 and then to run arpon -d -i <device connected> (or something like that).
Is there an easy way to do this? code...
I've searched everywhere how to find the connected device via bash, but i couldn't find anything.
I am trying to figure out the best server configuration for the following:Low power (I want to plug the server in and forget about it)High redundancy of data (I don't want to loose my music and documents!)The ability to stream music + movies to laptop (maybe subsonic or Jinzora)VPN server with IPsec or OpenVPN NAS $800 budget 2TB with ability to add more drives :Unix Server with software RAID (maybe RAID6)
VPN setup on virtual OS via VirtualBox
NAS setup on virtual OS via VirtualBox
My Questions:What would be the best raid configuration if I wanted at least 2TB of data and the ability to add more disks when the space begins to add up?What would be the best OS to use for setting up a software RAID (is a FakeRAID a better solution)?Does it make more sense to separate the VPN and NAS with different OS's?My goal will be to access my data from any computer from anywhere but mostly just my Laptop from work.

View 5 Replies View RelatedI'm building an Ubuntu 9.10 home server to essentially backup all my PCs to, serve media, and store other large data (I record music and film). Here's what I have as far as storage goes:
4GB CompactFlash: for OS
2x 500GB WD drives: intended for RAID-1 for backup (which I will in turn back to external drive on a weekly basis)
3x TB Hitachi drives: intended for RAID-5 for media and storage
Both RAIDs will be software-driven. Now, a few questions:
From what I've read, I can benefit from using LVM on top of the RAID. Is this true, and besides the complexity and potential difficulties in recovery in case of disaster, is there a downside to LVM?
Would I benefit at all from using smaller logical volumes on the RAID-5, or should I just make one at the full size of the drive?
Also from what I've read, it seems that XFS may be the best filesystem to use, from a stability and performance standpoint. Should I go that route, then? I suppose that if it IS beneficial to have multiple smaller logical volumes, then there may come a point that I need to shrink and grow these logical volumes, and if that's the case, it appears XFS is out of the question. What's the runner-up; Reiser? I currently have /swap and /home partitions on the CF card. I'd at the very least like to remove the /swap partition and just create a swap file on the RAID-5. Should I move my /home partition to the RAID-5 as well?
In our environment we are using EMC for storage. We are using Qlogic provided drivers and PowerPath and the OS is RHEL5.3. Currently we have 2 Luns connected in one of our server (emcpowera & emcpowerb) and storage team has allocated another 100Gb Lun to that system, my doubt is if I execute "ql-dynamic-tgt-lun-disc.sh" script that would be enough to detect the Lun and see the device under /dev/ as emcpowerc or I need to execute "powermt config" and "powermt save" commands also.
