Cluster with global file system

Hi
I setup Cluster 3.2 and all working fine
I follow the SUN doc of creating a global filesystem ( 1. newfs ... 2. mount under /global/foo etc). however I cannot mount under /global
say
mount /dev/global/dsk/d3s1 /global/foo ( will say "no such file or directory" )
But I can mount on say "/a"
It can be mounted only one layer beneath /
Why ?
Appreciate any hints
Thanks in advance
Brian

Well, assuming you are doing:
# mount -g /dev/global/dsk/d3s1 /global/foo
You'll need /global/foo to exist on all cluster nodes before you issue the mount command. The mount is an 'all or nothing' mount. It can't succeed on just a subset of cluster nodes, assuming they are all up. It must succeed on all.

Installing TREX global file system standalone

I am installing TREX 7.1.23 as a distributed system with central storage (SAN). However, according to multiple SAP documents, 7.1 does not yet allow you to install the global file system in a separate manner than the TREX system installation. Refer to TREX 7.1 central note 1003900 [https://service.sap.com/sap/support/notes/1003900].
SAP does indicate there is an interim solution with note 1258694 "TREX 7.1:Install TREX with Global File System (Windows). " [https://service.sap.com/sap/support/notes/1258694].
In this note it says to execute "install. cmd --action=install_cfs --target=<UNC path_to_NAS> --sid=<SAPSID>", but I have downloaded the standalone TREX 7.1 installation and there is no "install.cmd" file to be found!?
Has anyone seen this note and know how this is done or where this file can be found?
thanks!
John

will be redesigning this installation, so closing thread

Sun Cluster 3.2 - Global File Systems

Sun Cluster has a Global Filesystem (GFS) that supports read-only access throughout the cluster. However, only one node has write access.
In Linux a GFS filesystem allows it to be mounted by multiple nodes for simultaneous READ/WRITE access. Shouldn't this be the same for Solaris as well..
From the documentation that I have read,
"The global file system works on the same principle as the global device feature. That is, only one node at a time is the primary and actually communicates with the underlying file system. All other nodes use normal file semantics but actually communicate with the primary node over the same cluster transport. The primary node for the file system is always the same as the primary node for the device on which it is built"
The GFS is also known as Cluster File System or Proxy File system.
Our client believes that they can have their application "scaled" and all nodes in the cluster can have the ability to write to the globally mounted file system. My belief was, the only way this can occur is when the application has failed over and then the "write" would occur from the "primary" node whom is mastering the application at that time. Any input will be greatly appreciated or clarification needed. Thanks in advance.

Thank you very much, this helped :)
And how seamless is remounting of the block device LUN if one server dies?
Should some clustered services (FS clients such as app servers) be restarted
in case when the master node changes due to failover? Or is it truly seamless
as in a bit of latency added for duration of mounting the block device on another
node, with no fatal interruptions sent to the clients?
And, is it true that this solution is gratis, i.e. may legally be used for free
unless the customer wants support from Sun (authorized partners)? ;)

Problems mounting global file system

Hello all.
I have setup a Cluster using two Ultra10 machines called medusa & ultra10 (not very original I know) using Sun Cluster 3.1 with a Cluster patch bundle installed.
When one of the Ultra10 machines boots it complains about being unable to mount the global file system and for some reason tries to mount the node@1 file system when it is actually node 2.
on booting I receive the message on the macine ultra10
Type control-d to proceed with normal startup,
(or give root password for system maintenance): resuming boot
If I use control D to continue then the following happens:
ultra10:
ultra10:/ $ cat /etc/cluster/nodeid
2
ultra10:/ $ grep global /etc/vfstab
/dev/md/dsk/d32 /dev/md/rdsk/d32 /global/.devices/node@2 ufs 2 no global
ultra10:/ $ df -k | grep global
/dev/md/dsk/d32 493527 4803 439372 2% /global/.devices/node@1
medusa:
medusa:/ $ cat /etc/cluster/nodeid
1
medusa:/ $ grep global /etc/vfstab
/dev/md/dsk/d32 /dev/md/rdsk/d32 /global/.devices/node@1 ufs 2 no global
medusa:/ $ df -k | grep global
/dev/md/dsk/d32 493527 4803 439372 2% /global/.devices/node@1
Does anyone have any idea why the machine called ultra10 of node ID 2 is trying to mount the node ID 1 global file system when the correct entry is within the /etc/vfstab file?
Many thanks for any assistance.

Hmm, so for arguments sake, if I tried to mount both /dev/md/dsk/d50 devices to the same point in the filesystem for both nodes, it would mount OK?
I assumed the problem was because the device being used has the same name, and was confusing the Solaris OS when both nodes tried to mount it. Maybe some examples will help...
My cluster consists of two nodes, Helene and Dione. There is fibre-attached storage used for quorum, and website content. The output from scdidadm -L is:
1 helene:/dev/rdsk/c0t0d0 /dev/did/rdsk/d1
2 helene:/dev/rdsk/c0t1d0 /dev/did/rdsk/d2
3 helene:/dev/rdsk/c4t50002AC0001202D9d0 /dev/did/rdsk/d3
3 dione:/dev/rdsk/c4t50002AC0001202D9d0 /dev/did/rdsk/d3
4 dione:/dev/rdsk/c0t0d0 /dev/did/rdsk/d4
5 dione:/dev/rdsk/c0t1d0 /dev/did/rdsk/d5
This allows me to have identical entries in both host's /etc/vfstab files. There are also shared devices under /dev/global that can be accessed by both nodes. But the RAID devices are not referenced by anything from these directories (i.e. there's no /dev/global/md/dsk/50). I just thought it would make sense to have the option of global meta devices, but maybe that's just me!
Thanks again Tim! :D

Confusion with OCFS2 File system for OCR and Voting disk RHEL 5, Oracle11g,

Dear all,
I am in the process of installing Oracle 11g 3 Node RAC database
The environment on which i have to do this implementation is as follows:
Oracle 11g.
Red Hat Linux 5 x86
Oracle Clusterware
ASM
EMC Storage
250 Gb of Storage drive.
SAN
As of now i am in the process of installing Oracle Clusterware on the 3 nodes.
I have performed these tasks for the cluster installs.
1. Configure Kernel Parameters
2. Configure User Limits
3. Modify the /etc/pam.d/login file
4. Configure Operating System Users and Groups for Oracle Clusterware
5. Configure Oracle Clusterware Owner Environment
6. Install CVUQDISK rpm package
7. Configure the Hosts file
8. Verify the Network Setup
9. Configure the SSH on all Cluster Nodes (User Equivalence)
9. Enable the SSH on all Cluster Nodes (User Equivalence)
10. Install Oracle Cluster File System (OCFS2)
11.Verify the Installation of Oracle Cluster File System (OCFS2)
12. Configure the OCFS2 (/etc/ocfs2/cluster.conf)
13. Configure the O2CB Cluster Stack for OCFS2
BUT, here after i am a little bit confused on how to proceed further. The next step is to Format the disk and mount the OCFS2, Create Software Directories... so and so forth.
I asked my system admin to provide me two partitions so that i could format them with OCFS2 file system.
He wrote back to me saying.
*"Is what you want before I do it??*
*/dev/emcpowera1 is 3GB and formatted OCFS2.*
*/dev/emcpowera2 is 3GB and formatted OCFS2.*
*Are those big enough for you? If not, I can re-size and re-format them*
*before I mount them on the servers.*
*the SAN is shared storage. /dev/emcpowera is one of three LUNs on*
*the shared storage, and it's 214GB. Right now there are only two*
*partitions on it- the ones I listed below. I can repartition the LUN any*
*way you want it.*
*Where do you want these mounted at:*
*/dev/emcpowera1*
*/dev/emcpowera2*
*I was thinking if this mounting techique would work like so:*
*emcpowera1: /u01/shared_config/OCR_config*
*emcpowera2: /u01/shared_config/voting_disk*
*Let me know how you'd like them mounted."*
Please recommend me what i should convey to him so that i can ask him to the exact same thing.
My second question is, as we are using ASM, for which i am gonna configure ASM after clusterware installation, should i install Openfiler??
Pls refer the enviroment information i provided above and make recommendations.
As of now i am using Jeffery Hunters guide to install the entire setup. You think the entire install guide goes well with my enviroment??
http://www.oracle.com/technology/pub/articles/hunter_rac11gr1_iscsi.html?rssid=rss_otn_articles
Kind regards
MK

Thanks for ur reply Mufalani,
You have managed to solve half part of my query. But still i am stuck with what kind of mount point i should ask the system admin to create for OCR and Voting disk. Should i go with the mount point he is mentioning??
Let me put forth few more questions here.
1. Is 280 MB ok for OCR and voting disks respectively??
2. Should i ask the system admin to create 4 voting disk mount points and two for ocr??
3. As mentioned by the system admin.
*/u01/shared_config/OCR_config*
*/u01/shared_config/voting_disk*
Is this ok for creating the ocr and voting disks?
4. Can i use OCFS2 file system for formating the disk instead of using them as RAW device!!?
5. As u mentioned that Openfiler is not needed for Configuring ASM... Could you provide me the links which will guide me to create partition disks, voting disks and ocr disks!! I could not locate them on the doc or else were. I did find a couple of them, but was unable to identify a suitable one for my envoirement.

Problems with the File System Repository & User Mapping!

Hi All
I am having a problem with a file system repository, and setting up user mapping for that repository.
I have done the following:
Created a File System Repository
Created a Network Path
Created a System (Including the alias)
Now when I go into User Administration and select my user the is no user mapped systems to select.
All this system is doing is connecering to a folder on our File System.
Any help would be great as this is really frustrating!
Thanks
Phil

I am using EP7 Stack 11 and unfortunately the only options I have are:
user
admin
admin,user
It is currently set to admin, user and does not seem to work!

Crystal Reports XI String [255] limit with the File System Data driver...

I was trying to create a Crystal Reports XI report to return security permissions of files and folders. I have been able to successfully connect and return data using the File System Data driver as the Data Source; however the String limit on the ACL NT Security Field is 255 characters. The full string of data to be returned can be much longer than the 255 limit and I cannot find how to manipulate that parameter.
I am currently on Crystals XI and Crystal XI R2 and have applied the latest service packs but still see the issue. My Crystal Reports Database DLL for File System data ( crdb_FileSystem.dll ) is at Product Version 11.5.10.1263.
Is it possible to change string limits when using the File System Data driver as the Data Source? If so, how can that be accomplished. If not, is there another method to retrieve information with the Windows File System Data being the Data Source? Meaning, could I reach my end game objective of reporting on the Windows ACL's with Crystal through another method?

Hello,
This is a known issue. Early versions you could not create folder structures longer than 255 characters. With the updates to the various OS's this is now possible but CR did not allocate the same space required.
It's been tracked as an enhancement - ADAPT01174519 but set for a future release.
There are likely other ways of getting the info and then putting it into an Excel file format and using that as the data source.
I did a Google search and found this option: http://www.tomshardware.com/forum/16772-45-display-explorer-folders-tree-structure-export-excel
There are tools out there to do this kind of thing....
Thank you
Don

Btrfs with different file systems for different mount points?

Hey,
I finally bought a SSD, and I want to format it to f2fs (and fat to boot on UEFI) and install Arch on it, and in my old HDD I intend to have /home and /var and try btrfs on them, but I saw in Arch wiki that btrfs "Cannot use different file systems for different mount points.", it means I cannot have a / in f2fs and a /home in btrfs? What can I do? Better use XFS, ZFS or ext4 (I want the faster one)?
Thanks in advance and sorry my english.

pedrofleck wrote:Gosh, what was I thinking, thank you! (I still have a doubt: is btrfs the best option?)
Just a few weeks ago many of us were worrying about massive data loss due to a bug introduced in kernel 3.17 that caused corruption when using snapshots. Because btrfs is under heavy developement, this sort of thing can be expected. That said, I have my entire system running with btrfs. I have 4 volumes, two raid1, a raid0 and a jbod. I also run rsync to an ext4 partition and ntfs. Furthermore I make offline backups as well.
If you use btrfs make sure you have backups and make sure you are ready to use them. Also, make sure you check sum your backups. rsync has the option to use checksums in place of access times to determine what to sync.

Cannot uninstall Exchange 2013 from Server with REFS file system

EX2013 SP1 installed fine on the 2012 R2 server with REFS, but now I need to remove it and reinstall. When I go to uninstall it, I get an error that "the specified installation directory must be located on a NTFS file system". I have tried
via control panel and command line.
I could avoid the uninstall if I could replace the Enterprise Edition license key with a standard key. the "Change License Key" option only allows you to go from standard to enterprise.
Any advice on either issues? (uninstall from REFS or change enterprise key to standard key)
According to the below TechNet article REFS is supported for an install, but maybe not an uninstall
http://technet.microsoft.com/en-us/library/ee832792(v=exchg.150).aspx

Hi,
1. I suggest romving previous Exchange server via ADSIEdit.
NOTE: It is better to try the steps with the assistance of a MS support. Do remember to backup the AD.
2. Then reformat the file system to NTFS.
3. Last, reinstall the new standard Exchange version.
Thanks

Uninstall Oracle Culster (RAC) & Oracle Database with Raw File System (LVM)

Hello,
I have configured "Oracle RAC" with "Database" on Hp Unix 11.23 Platform. The shared storage is based on "raw" file system,which has mounted through "SAN" Storage. We have used total 18 LV (logical volumes) for oracle & clusterware.
By mistaken, I have configured wrong "Public, Private IP Address & Virtual IP Addresses" during RAC installation,thus my oracle "crs" is not working perfectly. So, is it possible to modify the "public,private & Virtual" IP Addresses? If Yes, provide me the step by step modification link.
Moreover, I would like to know certain steps to uninstall entire "Oracle Clusterware & Database." Kindly do the needful the "uninstallation" steps & is it necessary to remove & recreate LVM partitions, on which "oracle crs & database" has installed?
Advanced Thanks,
Nishith Vyas

Hi,
You haven't told anything about version...
By mistaken, I have configured wrong "Public, Private IP Address & Virtual IP Addresses" during RAC installation,thus my oracle "crs" is not working perfectly. So, is it possible to modify the "public,private & Virtual" IP Addresses? If Yes, provide me the step by step modification link.BTW, this thread has information that can drive You to this change:
Re: Is it possible?
Moreover, I would like to know certain steps to uninstall entire "Oracle Clusterware & Database." Kindly do the needful the "uninstallation" steps &Again... No versions, but You this thread can drive You to this
How to cleanup / remove RAC installation (CRS,RDBMS,ASM)
is it necessary to remove & recreate LVM partitions, on which "oracle crs & database" has installed?I don't think so. If all steps on uninstalling procedure don't work, You'll can try "zero" the information on the raw device using dd.
Hope it helps,

How to configure SunCluster 3.1 8/05 with Network File System

Hi Gurus,
does anyone has experience to configure SC3.1 8/05 using nas as cluster filesystems?
I've found this document in docs.sun.com:
Installing and Maintaining Network Appliance Network-Attached Storage Devices in a Sun Cluster Environment
This document explain how to use scnas and scnasdir commands, how to use netapp as quorum device.
It seems incomplete, after I configure netapp in cluster what I need to do to register netapp filesystems in the resource group?
Thx,

Troubles with GPT file system

Hello everybody,
i got a motherboard MSI 760GA-P43FX
and i experience the following issue:
i bought a SSD disk KINGSTON SSDNOW 120GB, trying to do a fresh windows 7 installation (64bit) on it.
Later, i need to install the TRUE CRYPT to encrypt that SSD harddrive,
unfortunately, the WIN7 formats the SSD disk with an EFI (GPT) file system again and again,
and the TRUE CRYPT does not support GPT file format only the older MBR.
I red plenty of stuff on this issue, some people who got lucky and bought other motherboard
can choose between EFI and old MBR (Legacy) when booting from the DVD drive.
Unfortunately, i could not find any option in my BIOS to disable the EFI
or on the boot-up to choose non-EFI booting from DVD.
(i red somewhere when i would be able to choose the older non-EFI booting from DVD when installing the WIN7,
the WIN7 will automaticaly format the SSD with a MBR which is what i need.)
Please dont tell me i need to buy another MB, the funny thing is, i bought the same motherboards,
installing the same system, all is the same, SSD, CPU, RAM, everything is the same,
but on my 2nd machine i am just not able to go through the EFI issue.
On my 1st machine i have installed everything properly, SSD works fine with the true crypt,
all is fine! I assume the version of BIOS could be different or i dont know.
Anyway, I wont use any HDD bigger then 2 TB so i dont need any EFI file system.
I am desperate, can anyone help?
thanks!

Hello t:
Welcome to Apple discussions.
Do those applications open from the application folder? If they do:
Try trashing a preference file and restarting (com.apple.dock.plist).
If that does not help, drag the icons that do not work off the dock (poof sound). Then go to the application folder and drag the appropriate icon to the dock.

How to connect SharePoint Document Library with Local file system?

Hi
I have a SharePoint Document library and in my local system i have 3TB files. It is very difficult to upload 3TB files in SharePoint.
I want a file details in SharePoint Document Library but physical file would be in local.
While click the file in Document library. The document should open from local.
Anyone help me on it.
Thanks & Regards
Poomani Sankaran

Hi,
your requirement doesn't work out-of-the-box as all data uploaded to SharePoint needs to be stored in SQL database. Thus in your case 3 TB of fileshare would need to move to SQL.
In case you don't want to go this way, there are 3rd party vendors who offer Software like AvePoint Connector. Products like these use SQL RBS (Storage Externalization API) so that files remain in your file system but metadata is kept in SharePoint. If you
need more information on that, please let me know.

Dennis
