INTEL SS4200-E concerns

Guys i just purchased this network storage device, and i think i made the wrong choice. I would really need your help on answering some questions.

 

-Is it absolutely nesecary to implement raid on the drives installed? Cause i dont need RAID. I only care about utilizing 100% disk space of the drives, i dont want mirroring and backups and stuff.

 

-Does each drive need to be formatted upon insertion or can you have data on them. Cause 2 of the 4 Disks I intend to use,contain data and they're almost full. One of them has less than 8 GB disk space left.

 

-Are the drives reformatted on linux format? Does that meann i wasted 8 hours of my day formatting 2x1.5TB Seagate drives on NTFS format?

 

Please give me some hope, cause if what i fear is about to happen, that would be highly inconvenient.

    Hi Rock,

    1- Since you do not want RAID at all, you can always proceed with Linear Configuration. A linear disk configuration does not offer any data protection. If you lose a hard disk, data loss will occur. A linear configuration is similar to using multiple hard disks in a regular computer. Each disk is an independent entity, and the data on it is self-contained. You can add or remove the disks without affecting the other disks. All the available disk space is used for data.
    If your storage system has only one disk, you must use a linear configuration. However, you can use a linear configuration for two, three, or four disks as well.

     

    2- When you insert a drive, it is to be formatted for RAID rebuild or new configuration however I have not experimented with Linear Configuration as in your typical scenario however I do think you might not be able to access your existing data. I am not saying that it's impossible but I will check & revert to you on this one.

     

    3- As for the volume & partition information:

    • SS4200-E operating system volume is mounted as /dev/hda1 and is a Linux ext2 partition. hda1 is a 256MB DOM (Disk on Memory) module installed in the motherboard IDE port.
    • The data is in an ext3 journaled file system on an lvm2 logical volume on an md raid (RAID 1 for two disks and RAID 5 for four disks) array mounted as /dev/evms/md0vol1. The array consists of a partition from each of the disks. There is only one partition on each disk that spans the entire disk.
    • The operating system used by the user determines which option you should choose.
      • Windows/Mac OS X user (CIFS)
      • Linux/Other Mac user (NFS).

    Hope this answers your questions, as for the 2nd question, I will double check and revert you know, keep in touch for that.

    Javed,

     

    This is a 4200 he is talking about. He has to have RAID, this is not a 4000 unit.

    I have tried to connect to the /public folder on an SS4200-E to no avail.

    I tried both the CLI "mount -t nfs /ip-num/public /mnt" and variations thereof.

    also tried using the Webmin gui interface. It seems that the nfs server on the

    device can't be seen/found.

     

    - I am upgraded to the latest firmware on the intel site.

    - I enabled nfs in the network services.

    - I am trying to connect from an UBUNTU 8.04 SERVER running

      LAMP + Webmin/Virtualmin.

     

    Is the nfs server functional?

    OK, I can report that the nfs server is indeed functional. I used a Windows nfs browser

    and found out the share name format  is nfs://ip-addr/mnt/soho_storage/samba/shares/shared_folder_name

    so in linux you would do:

    >mount.nfs  /192.168.1.x/mnt/soho_storage/samba/shares/your_shared_folder_name    /your_mount_point

     

    I still get a permission error on my linux server but I was able to browse using the Windows NFS browser.

    Good to know and thank you for the update Oak.

     

    Yes Flash I know Rock is talking about SS4200-E and I gave him an update on that. SS4000-E has been discontinued long time back and in this case, Rock wanted help regarding SS4200-E.

     

    Rock, I checked and Linear RAID configurations in SS4200-E is not possible at the moment.

     

    Thank you everyone for pitching in and thank you for using Intel.

    Wasn't the point of his post to get 100% data storage usage... He could always do a RAID 0 setup... risky, but 100% data usage.

    - well or you can always get the SS4200-EHW(or take out the installed DOM) without preinstalled intel OS and put some OS on and just use it as a normal computer on network for storage as anyway it is based on a desktop mainboard..what was it 845 chipset or something like that? Well I know for that case the only advantage of this system would be that it has a little bit nice looking chassis(depends on point of view):).

    - well the advanced option would be just adjust the linux OS that is running on that storage. Come on guys, it's just linux and you can do everything with it (if you find out how to get all 'permisions');)

    - well I know the RAID 0 option is really risky..I would personally never use it for any data I would like to have..when it crashes you can just forget your data, but when a non-raid disk crashes you can recover it always at home easily. So RAID 0 just for something where you need amazing transfer speeds but the data is not important or always easily recoverable.

    nfs is working just fine here. I'm actually using autofs on Ubuntu Karmic. Note that Paths to NFS Shared Folders are in the following form: /nfs/SharedFolderName (This is mentioned in the gui somewhere)

     

    So to follow your example, try this: sudo mount -t nfs /ip-num/nfs/SharedFolderName  /mnt/SharedFolderName

    The /mnt/SharedFolderName must exist.

     

    Then, try to access the share as a regular user, not root.

     

    Let us know how it goes.
