I am having problems installing Debian 7.7 i386 on the newest HP DL380 GEN9 server with P440ar storage array. The disk detection during installation fails to detect the array.
I have pinpointed the problem to hpsa.ko driver to be outdated as I need a minimum version from September 2014. I have already tried following the guide on " [URL]" but the driver compiling from sources fails (guide is from 2012).
Here is where I got the latest sources: [URL]....
Is there any possible way to install this debian version with this storage array? Newer kernel version is really not an option for me.
"3.2.0-4-686-pae #1 SMP Debian 3.2.65-1+deb7u2 i686 GNU/Linux"
I'm trying to delete directories (long story, Mac temp files there, Windows not cooperating) on a sever connected to a HP 20 Modular Smart Array set up as RAID5. System currently running Windows. I've booted from a 9.10 LiveCD but can't see the external drives. Is it correct that I need to install mdadm to "see" those drives from LiveCD? From a different machine (linux) I can mount the drive using samba like so:
sudo smbmount //IP address/hostname RAID5 Root Share /mnt/ntserver -o username=smith,password=abcde123
I have admin privileges on the Windows OS. In linux (or Windows beforehand), is it possible to take ownership of the directories so that I can do a rm -f -r <dir> ?
I have an Acer Altos EasyStore SATA NAS box that hung, the only way to reboot was to crash the system (unplug it). Upon reboot it was not recognising the hard drives (it wanted to do a destructive reinitialize). Most of the importent data was backed up, however some was overlooked and we'd quite like to get it back. Removing the disks and placing them in a PC with enough SATA bays to cope, and booting with a live linux distribution (System Rescue CD) I can see the 4 drives are not suffering hardware error and that the original partions exist. Using mdadm I can assemble the Arrays without error (seems to be three but the only one I am concerned with is the RAID5 array of about 3TB). /dev/m1p2 mounts as a loopdevice once an offset is entered. In turn this mounts as an XFS parition. However despite df showing the partition almost to be full. ls -l or ls -a on the mount point shows it to be empty!
I got thusfar using a translation from a German language forum, unfortunately I only speak a little German, and the only other English language post on a simlilar matter I found within that site had no replies. The next step was to unmount loop, then run xfs_chack and xfs_repair on the file system. xfs_check returns that there is are a few dir size and offset errors along with link count mismatches. This I would presume normal for a file system that has become slightly corrupted. xfs_repair (version 3.0.3) gets as far as Phase 3 it finds and corrects zerolength entries, offsets on directories and bogus inode numbers. However the final two lines are:
Code:
realloc failed in blkent_append (2671166480 bytes)
zsh: segmentation fault xfs_repair /dev/loop1
A search on the error missing out data size just returns code to generate it, is anybody able to explain what it means? Also remounting hard drive, ls and varients of still do not return anything. Am I missing some thing (root I am logged in with now would have different credentials presumably to root on the NAS box, so how do I get around this)?
My goal is to connect up a bunch of CentOS 5.6 servers to storage array which is running as an SRP target. These servers will be running eventually as Xen hypervisors. I'm using Mellanox Infiniband cards and a Qlogic Infiniband switch.
OFED drivers are already installed as standard. I have done the following.
1. Base install of CentOS 5.6 X86_64
2. Installed the following packages...
openib
ibutils
srptools
infiniband-diags
opensm
[Code]...
It works perfectly and connects to the target immediately with great results. I'd just like this to happen correctly on startup.
To work around the issue I have added the line srp_daemon -e -o into the init script for opensm /etc/init.d/opensmd but it doesnt always start the srp_daemon process. Its rather hit and miss
I'd really like srp_daemon to run as a service with a proper init script but I wouldnt know how to write one. I understand that this issue has been addressed in the RHEL6 srptools package but that doesnt help me because the software I intend to use on these servers specifically requires 5.
is there a way or terminal command to disable access to a USB storage device upon insertion given that it is not permitted?

I just discovered that inserting any USB drive causes an immediate hang of the system. The keyboard caps lock and scroll lock lights blink. Only recourse is to power cycle the system. This is after installing Kubuntu 9.10 in January, I don't believe I had occasion to insert a USB drive until tonight. 100% reliable. No entries in logs, presumably because it hangs the kernel when it happens. The /var/log/kern.log file has been corrupted due to file system damage (1+ sectors of some other file inserted into chain) and probably other files as well.
I've not had occasion to report other bugs, but I've found no way to report anything other than application bugs. I tried using "ubuntu-bug kernel" which helpfully said there was no such application as 'kernel' and has been busy "collecting problem information" for the last half hour or more. Somehow I don't think its ever going to finish.
The crash only happens when booted into Kubuntu 9.10. If I boot off of 9.04 then USB drives work fine. Both USB drives I've tried reliably produce the crash. One is a random cheap USB thumb drive (imprinted "Cisco"), the other is a 16GB Corsair Voyager.

But there are some Bad Blocks on the NAND.Hence copy is not complete. Although on Linux machine there is no error message. Now , what is there in a normal pen drive which manages the Bad Block or what am I missing so that such Bad Blocks are managed.

we have purchased the Dell PowerVault NF 500 NAS Storage Box with Window Storage server 2003 is Installed.we have LDAP server for authentication the user in network for accessing network resources.All ubuntu users on client side use ubuntu(LDAP server )for user authentication.when a user logon on client side machine his home directory is created on client machine .
but we want to use the NAS storage device to store the home directories of user.we want to implement that ,whenever a user logon his home directory is created on powerValut NF 500 storage device so that all user data is stored centrally for taking the backup .we want to mount NAS storage device so that user uses when they login and create user profile.
I need to auto-mount a storage device AND execute a program passing mount point path to it. How can i do this? I'd like to avoid polling for new storage devices. I'm looking for something like acpid for ACPI events, but working with storage plug events instead.

I can either do it manually, or install some other file manager that has this capability. This leads me to my question, I've noticed that if I install Nautilus, which automatically mounts android devices OotB, I get this functionality in Thunar as well. This leads me to believe that there is clearly a dependency package of some kind installed when running apt-get install nautilus that enables it, It'd be great to get this functionality in Thunar without having all the nautilus packages just littering about for no good reason. the required package is gvfs-backends, which I should have realized when I was unable to browse smb:// addresses. You forget a lot when you only make a fresh install once every 2 years or so.

I've searched high and low, and can't figure this one out. I have a older Olympus Camera (2001 or so). When I plug in the USB connection, I get the following log output:

Secondly, the drive is not mounted in the FS, but when I run gphoto2 I get the following error:
$ gphoto2 --list-config

An error occurred in the io-library ('Could not lock the device'): Camera is already in use.
*** Error (-60: 'Could not lock the device') ***
What command will unmount the drive. For example in Nautilus, I can right click and select "Safely Remove Device". After doing that, the /dev/sg7 and /dev/sdg devices are removed.
The output of gphoto2 is then:

I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.

View 2 Replies View RelatedCost effective (the people want cheap) solution to increase server storage space with as little impact on throughput (what I want) as possible. I have a server that sends instructions to 20 clients to perform certain tasks. The clients send gigs of data back to the server for storage.
BACKGROUND INFORMATION
Network: Gigabit Ethernet
Clients: (20) HP, Solaris, Linux
Linux Server: Dell R805 PowerEdge (QUAD Core Athlons 16 gigs of ram, 4 gigabit ports.
Selected directories are mounted (NFS) by clients. One directory to be mounted by the clients contains executable files. Mount commands are sent from the server (rsh) to the clients. Yes I know (ssh) but this is how the software was originally written so let's go with it.
The clients then receive commands to execute the binaries contained within the mounted directory. The binaries basically create an image of the clients filesystem including special applications. The client then sends the files and directories to the server which stores this �image�. This process can be reversed to restore a client to the initial baseline image.
In a nut shell, 20 clients are sending gigs of data to the server for storage. I need to attach a NAS (gigabit) to extend the storage capability of the server. The server would mount (NFS) to the hard drives on the NAS. The NAS, configured as a �direct attached storage� device (DAS), means the storage device is connected directly to the server and not the network (which makes it a DAS). This would provide direct storage expansion for the server. However, this configuration cannot be a bottleneck that significantly hinders performance.
Clients <---data---->Server<----storage---->DAS/NAS
1) Will a low end NAS (gigabit port) work? (NetGear 1TB ReadyNAS Duo, RND2110-100NAS) or something with a higher rated throughput (QNAP TS-239 Pro II)
2) Low end won't work, go with �?
3) Does the processor on the NAS play any role that would determine the performance of this configuration given that the server would mount directly to a directory on this device (DAS/NAS)?
Is there a way to determine the IO size that is being used for reads and writes to an attached storage device? I am trying to pattern the IO sequences to storage. I have seen mentions to max_sectors_kb but the notes indicated that changing this value did not change the IO size to the storage.

So my aim is to install openSUSEx64 11.3 onto my Macbook; but for whatever reason, upon boot-up, the system won't recognize the USB thumb drive with the expanded image of openSUSE on it. I followed steps in Terminal to expand the image onto the said USB stick and know it worked properly because Terminal said "Process Completed." Do I need a special type of USB thumb drive or am I missing something? I am using a late-2009 Macbook. By the way, these were the steps used to prep the USB thumb stick:
1. Open a Terminal (under Utilities)
2. Run diskutil list to get the current list of devices
3. Insert your flash media
4. Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)
5. Run diskutil unmountDisk /dev/diskN
6. Execute sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m
7. Run diskutil eject /dev/diskN and remove your flash media when the command completes
