Resize the zfs on solaris 5.10

hi All,
i have solaris 5.10 serving zfs filesystem via equallogic iscsi , i have resized the luns from the equallogic gui but i do not know how to resize at the solaris server. what are the steps? can i do it while filesystem online?

thanks guys for your replies, here is the output of the command " zpool status -v"
can someone give me a step by step on how to resize, also, can i do the resize while the filesystems online.? anything else i need to worry about doing this resize process?

  • Resize mirrored ZFS rpool

    I have a ZFS rpool mirrored with 2 hard disks. I need to resize it with bigger capacity. Below is my questions;
    1. Can we resize a mirrored rpool?
    2. If yes, How? (Please provide me the source) Thanks.
    3. If the rpool is using local disk and i have other storage LUNs can be attached... what is the best practice to increase the rpool size?
    4. If resizing is not possible, can someone shed some light how could we migrate a mount point from rpool (local disk) to new pool (SAN storage). Please advise.
    Thank you.

    Yes, it is possible to increase the root pool size by either attaching a larger disk and detaching the smaller disk or by using zpool replace to do an outright replacement. If you attach a disk from remote storage, so that you have a local disk and remote disk for a mirrored root pool, then there is a risk that if the remote disk is slow to come up after a boot, for example, the pool might be degraded. Similarly, if you use remote storage for both root pool disks. Forcing loading the drivers early in the boot process can help this.
    Which Solaris 10 release is this?
    Does the existing root pool disk have existing unused slices or is all the disk space in slice 0?
    There is a way to expand the root pool disk slice if existing unused slices exist but its a bit more complicated, but I can walk you through it.
    The doc that describes root pool disk replacement is here:

  • Zfs on solaris 10 and home directory creation

    I am using samba and a root preexec script to automatically create individual ZFS filesystem home directories with quotas on a Solaris 10 server that is a member of a Windows 2003 domain.
    There are about 60,000 users in Active Directory.
    My question is about best practice.
    I am worried about the overhead of having 60,000 ZFS filesytems to mount and run on Solaris 10 ?
    Edited by: fatfish on Apr 29, 2010 2:51 AM

    Testing results as follows -
    Solaris 10 10/09 running as VM on Vmware ESX server with 7 GB RAM 1 CPU 64 bit.
    ZFS pool created with three 50 GB FC LUNS from our SAN (Hardware RAID5). There are shared to ESX server and presented to the Solaris VM as Raw Device Mappings (no VMFS).
    I set up a simple script to create 3000 ZFS filesystem home directories
    #!/usr/bin/bash
    for i in {1..3000}
    do
    zfs create tank/users/test$i
    echo "$i created"
    done
    The first 1000 created very quickly.
    By the time I reached about 2000 each filesystem was taking almost 5 seconds to create. Way too long. I gave up after about 2500.
    So I rebooted.
    The 2500 ZFS filesystems mounted in about 4 seconds, so no problem there.
    The problem I have is why do the ZFS file system creation time drop of and become unworkable? I tried again to add to the pool after reboot and there was the same slow creation time.
    Am I better off with just one ZFS file system with 60,000 userquotas applied and lots of ordinary user home directories created under that with mkdir?

  • How to convert ufs to zfs in Solaris 10

    After installinng solaris 10 i wnat to convert my ufs to zfs , how can i do that , unfortunately tehre is no documentation available in docs.sun.com. any help is greatly appreciated

    I found a document on Sun site long time ago titled "The best file system in the world" (Peter Baer Galvin's as far as I remember). I believe it can be still found somewhere there, and here are some of citations that may be helpful:
    There are many things that ZFS is, currently, and a few that it is not. The most frustrating current limit is that ZFS cannot be the root file system. A project is underway to resolve that issue, however. It certainly would be nice to install a system with ZFS as the root file system and then to have features like snapshots available for systems work. Consider taking a snapshot, making a change that causes a problem on the system (e.g., installing a bad patch), and then reverting the system to its pre-patch state by restoring the snapshot.
    Also, ZFS can be imported and exported, but it is not a true "clustered file system" in that only one host can access the file system at one time.
    An open issue is the support of ISVs, such as Oracle, for the use of a ZFS file system to store their data. I'm sure this will come over time.
    Hot spares are not implemented currently. If a disk fails, a zpool replace command must be executed for the bad disk to be replaced by a good one.
    A mirror can be removed from a mirror pair by the zpool detach command, but RAID-Z sets and non-mirrored disks currently cannot be removed from a pool.
    Also, currently there is no built-in encryption, and at this point ZFS is a Solaris-only feature. Whether ports will be done to other operating systems remains to be seen.
    Just a brief word on the readiness of ZFS for production use. Usually, a new file system would not even be considered for production use for quite a while after its first ship. ZFS, on the other hand, may well garner production use immediately on its production ship. The testing that has gone into ZFS is astounding, and in fact testing was considered a first-class component of the ZFS design and implementation.

  • ZFS in Solaris 10

    Hi all,
    Two month ago, I have download Solaris 10, and there aren't the ZFS filesystem, so I want to know if Solaris have been upgraded and if it now contains the ZFS filesystem.
    Thanks.
    Willits

    There are no Solaris 10 update releases at this time.
    There are newer Solaris Express releases, but they don't include
    ZFS.

  • ZFS in solaris 10 x86 ?

    In the Solaris 10 installation, I can only set the filesystem to UFS ? I want to know if ZFS is in Solaris 10 for X86 and if yes, how I can enable it.
    Thanks.
    Willits

    I'm afraid ZFS didn't make it in time for the first official
    Solaris 10 release ('GA') for either sparc or x86.
    Promised for an early update release.
    BTW, does anyone know what GA stands for?

  • Can't boot with zfs root - Solaris 10 u6

    Having installed Solaris 10 u6 on one disk with native ufs and made this work by adding the the following entries
    /etc/driver_aliases
    glm pci1000,f
    /etc/path_to_inst
    <lang pci string for my scsi controller> glm
    which are needed since the driver selected by default are the ncsr scsi controller driver that do not work in 64 bit.
    Now I would like to create a new boot env. on a second disk on the same scsi controller, but use zfs instead.
    Using Live Upgrade to create a new boot env on the second disk with zfs as file system worked fine.
    But when trying to boot of it I get the following error
    spa_import_rootpool: error 22
    panic[cpu0]/thread=fffffffffbc26ba0: cannot mount root path /pci@0,0-pci1002,4384@14,4/pci1000@1000@5/sd@1,0:a
    Well that's the same error I got with ufs before making the above mentioned changes /etc/driver_aliases and path_to_install
    But that seems not to be enough when using zfs.
    What am I missing ??

    Hmm I dropped the live upgrade from ufs to zfs because I was not 100% sure it worked.
    Then I did a reinstall selecting to use zfs during the install and made the changes to driver_aliases and path_to_inst before the 1'st reboot.
    The system came up fine on the 1'st reboot and did use the glm scsi driver and running in 64bit.
    But that was it. When the system then was rebooted (where it made a new boot-archive) it stopped working. Same error as before.
    I have managed to get it to boot in 32bit mode but still the same error (thats independent of what scsi driver used.)
    In all cases it does pop the SunOS Relase banner and it do load the driver (ncrs or glm) and detects the disks in the correct path and numbering.
    But it fails to load the file system.
    So basically the current status are no-go if you need to use the ncrs/glm scsi driver to access the disks with your zfs root pool.
    File-Safe works and can mount the zfs root pool, but that's no fun as server OS :(

  • Do I need to resize the sparsebundle file after migrating to new larger AirPort Time Capsule?

    Just upgraded my Airport Time Capsule from an old 1TB to a new 2TB version.
    I have migrated the sparse.bundle file by using the ethernet method but now I want to know if I need to resize the file using Disk Utility or does it happen automatically? If it doesn't resize automatically then Apple should at least have some option to automate this process as it seems a natural request.
    Over time people would want to continue using their same old back up and just allow the file to get bigger as it is moved onto a newer larger device and still have access to all the previous old backups all on one device/system.

    It should continue to resize automatically or would if Yosemite worked properly.. since TM in Yosemite is lousy it might well need you to fix it.. It isn't hard.

  • Photoshop CC: Have a template that I moved image into.  Image is too small.  How do I resize the image while in the template?  Or must I go to original image file and resize there again and again until I get the right fit?

    I have a template that I am able to plug different pictures into at different times.  The problem is that when I plug an image into that template, I find that the image is either too big or too small.  Is there a way to plug the image into the template and resize the image (and not the template itself) OR will I have to go to the file with the original image and resize it there and then try to plug it in to the template to see if it fits------and if it does not fit, go back to the original file with the image and resize it again and see if that fits---and so on and so on...........?  I have tried the" image size" option but it's hit or miss------mostly miss!
    Thanks!

    Read up on Smart Objects. It looks like you have no idea as to how to create and use them.
    Jut create a Smart Object from the layer containing whatever it image it is that you are "plugging into your template".  But you do need to learn the application at its most basic levels.
    Photoshop is a professional level application that makes no apologies for its very long and steep learning curve.  You cannot learn Photoshop in a forum, one question at a time.
    Or is it possible that you don't even have Photoshop proper but the stripped-down Photoshop Elements?"
    If the latter is the case, you're in the wrong forum.  This is not the Elements forum.
    Here's the link to the forum you would want if you're working in Elements.:

    If you do have Photoshop proper, please provide the exact version number of that application and of your OS.

  • How do I stop iPhone Safari from dynamically resizing the visual viewport?

    Sorry I post this here, but I couldn't access the developer forums (no error given, it just keeps returning me to this page https://developer.apple.com/devforums/) I'm not even sure wether that's been moved here and it's just the redirection non working.
    I need to Stop iPhone Safari from dynamically resizing the visual viewport, or in other words, to stop it from trying to "fit" the layout into the viewport.
    Why?
    Because any recalculation javascript does on absolutely positioned elements makes the whole site super IRRESPONSIVE.
    I don't know wether the issue is the element going out the already-set layout viewport (which triggers the page resizing to fit the visual viewport) or just the calculations being made constantly, but I can stop the calculations from happening when not "touching" the screen, but I need a way to stop the page resizing.
    I tried setting the viewport width to 1040px, as my layout width, and it fixed the header's width being narrower than the body (or shifted left?), but the whole page is still resized with every motion-frame (one every 3 seconds, due to overloading the redrawing engine)
    Is there a way to prevent that?

    No, that link doesn't solve it. It just says the same is found everywhere online.
    There's probably no way to do it, as per their way they "accidentally" omitted the oposite case: the page being wider than 980. They only mention what to do if the site is narrower. Something I learned is big companies (with reputation management) could let you run in circles for years no answer rather than telling you something is not possible.
    I'm the developer (can't access the dev forums, don't know why) and I DID setup the viewport, scale and other properties but none of them stopped from re-fitting the new re-sized layout in the viewport. They just ensure the "initial" view.
    I think the feature I'm looking for must be achieved with some JavaScript function targeting Safari-proprietary variable/property… if even possible.
    I just had to make things never reaching the edge until somebody contributes something useful

  • I am using a doc formatted on excel --- how do i resize the doc to fit on one page?

    I am using a document that was formatted in excel (on a PC) --- how do i resize the document to print on one page?

    Hi phylw,
    Here is one way. View > Show Print View. At the bottom of the window is a slider control called Content Scale. Slide to the left to shrink the document.
    Under File > Print... you will see a print preview that tells you how many pages the document now occupies.

  • Cannot resize the albums in album view in Itunes 11.  For those of us with large libraries (160gb), this is extremely frustrating.  I want to make the artwork smaller.  This seems to be a serious oversight.

    Cannot resize the albums in album view in Itunes 11.  For those of us with large libraries (160gb), this is extremely frustrating.  I want to make the artwork smaller.  This seems to be a serious oversight.

    I agree.
    It was very useful to reduce everything to small and quickly scan down looking for missing artwork.
    Particularly useful when I only connect to the machine with iTunes via screen sharing, so everything can be a bit slower to scroll through at times.
    In fact, itunes 11 when used purely as a server for Apple TV etc is a downgrade in usability IMO, as they've got rid of some of the useful views that helped me manage my library remotely.

  • Is it possible to resize the partitions without losing data?

    I have following issue:
    I have dual-boot Arch with Windows XP. I created 4 partitions: 40GB XP's system disk (ntfs), 80GB ntfs data disk, 1GB swap and 25GB Linux partition.
    But I am running XP so rarely, that it is frustrating, that I have most of my data on ntfs partition... I'd like to wipe out that 80GB ntfs, resize the system ntfs partition up to for example 60GB, and add the remaining 60GB to my linux ext3 partition (because I'm running out of free space recently...).
    Has anyone done something like this, and how safe it is (if possible at all)
    Yes, I have read this: http://wiki.archlinux.org/index.php/Res … _partition, and a few more.
    I just don't have time to reinstall both systems (especially I would not like to install Windows, because I'd rather install Vista from my recovery disk, than hack the XP to work again...), and if some issues are likely to appear, then I'll give it up for now .

    It's trivial using gparted, but as with any similar operation, you run the risk of losing data - so you'd better backup.

  • How to find out the info regarding Solaris, server hang or shutdown.

    Hi
    As I am handling the Solaris 9 Server remotely.
    As in last week the server has stopped to respond suddenly, we have tried to ping, ssh which was not working. As ultimately we have asked the Data Centre Team to hard reboot the same, to resolve the issue.
    In the same ref I would like to know how we come to know the reason, what caused to reboot the same, i.e . any log file, etc..

  • No Disk meet the criteria for Solaris installation

    Hi all, I have a problem when trying to install Solaris 8 (Intel) on my PC. There are some funny things happened while installing the OS.
    1.) My motherboard does not support booting from CD-ROM, so I downloaded a Device Assistant Boot Disk to boot it up. Then I use dd.exe to make the boot disk from the image, I have tried many times that after creating the boot disk, this boot disk will contain 512 bytes of bad sector. So why?
    2.) After using this boot disk to boot up and install the OS, before entering to the detection of the bus type stuff (still on the white screen), at the bottom of the screen, it says "ata_command select failed ... ...", what does this mean?
    3.) When the system go back to the white screen with language selection, I choose English (which is 1), and the system try to find my hard disk, but it failed and says "No Disk meet the criteria for Solaris installation" with a new line saying "installation documenation found.". So what is happening?
    Appreciate for any help.
