High disk write percentage

October 1, 2015, 8:22 am
$

What could be causing the write percentage to be very high on my 2008 R2 servers? I ran diskmon to see what the disk activity looked like and it's almost all writes, even when I'm the only user logged in and not running any programs. I am not seeing any performance problems, latency, etc, but it strikes me as odd that there is so much writing happening. I'm also not seeing any problem with disk space being used up, so it must be processes that are constantly overwriting something?

I'm seeing the same type of activity on physical servers and VMs. The VMs are on an equallogic san, and SanHQ shows above 95% write percentage pretty consistently on the Windows server LUNs. FWIW. most of these servers are in their own LUNs, and they are separate from the data LUNs.

Is this normal?

Failed SMB Connections - Server Not Found

I have a Windows 7 Pro client (through VPN tunnel) that can connect RDP, HTTP/S, SMB, and PING to Server A (Server 2008) but cannot map any SMB shares (by FQDN or IP) to Server B (Server 2008 R2). Client can RDP, HTTP/S and PING to Server B. Both servers are in the same LAN segment and sitting on same VMware host.

Where do I even begin to look?!? Any help would be appreciated.

Scripting techniques for shares on Windows 2008 R2 Clustered File Server

Scenario: Windows Server 2008 R2 Clustered FS, two nodes.

Needs: I have to move all file system structure from a clustered disk to another, then recreate all shares and quotas.

Now I had found an unsopported way to backup quotas by saving disk "System Volume Information" and restoring on new disk.

About shares: is there any way to script shares export and import when configured at cluster level? Unfortunately I can't use Get-SmbShare and Set-SmbShare because they're included only from Windows Server 2012.

Any advice about it?

DFS Advice

October 1, 2015, 4:30 am

Looking for some guidance on how we should setup some new infrastructure we've recently purchased as part of a SAN replacement project.

Current setup is that we have multiple virtual Windows 2003 file servers that have Domain DFS Roots on them.

We've purchased 4x HP StoreEasy 3830's which are setup as 2+2 node clusters. One cluster is at our production site and one is at our DR site.

We're migrating all of the DFS roots and data on to these and are hoping to have high available/seamless transition between sites if we need to invoke DR.

We're quite confident on how we can setup the live site by using file server cluster services but are a little unsure on how to setup the DFS for the DR site.

We also use Access Based Enumeration on the Server 2003 which has resulted in us having to cacls commands to apply NTFS permissions to each DFS Link created.

1. Can anyone recommend or provide any links to how we can setup the two clusters so DFS/data is replicating and accessible?

2. Even if we get the data replicating, will we have an issue with the ntfs permissions on each DFS link, because the cacls command points to the local server/cluster name if we fail over connections to the second cluster it all changes and the permissions will not be in place? How can we resolve this issue?

Thank you in advance

Bizarre DFSRoots subfolder permission inheritance issue

October 2, 2015, 3:35 am
$

Hi, I really hope somebody can shed some light on this...

Once in a while we get an issue where some (and sometimes all) users get niggling issues, such as the 'Documents' link in Start Menu not working (other issues within various applications also crop up at the same time).

We have various namespaces set up on our domain, one of which is called \\stockportgrsch.net\userfiles.
There are 3 namespace servers for this namespace (FS04, FS05 and FS06).

When the above issue arises, if I look at the permissions for 'C:\DFSRoots\Userfiles' on each of the servers, I will find that on at least one of them (and again sometimes all), permission inheritance seems to be broken.
By broken I mean that only 'Administrators' are showing in the ACL, but when I look at inheritance it thinks it's turned on.
The only fix I have at present is to click 'Disable Inheritance', click Apply, and then click 'Enable Inheritance'.
This puts the permissions back correctly, as below.
I know I can do this every time but can't keep checking this and obviously am worried that this might be a symptom to a wider issue!

Users Unable to Access/Save Files With Full Permissions

Hello,

We have several users who are unable to save and/or access certain files within their home directory.  The users had no issues on Friday to access/save these files, no permissions have been changed prior to the incident (only after the incident for testing) and no updates have been applied to the machines the users are using to access the server.

Things I have checked:

  1. Users have Full Permissions over the location/file they are trying to access
  2. Users are Owners for the "Share" permissions on the folder they are trying to save to
  3. Removed Inherited permissions and tried to access without success
  4. Restarted client machines to no avail
  5. With a specific file, I tried to move it to other locations within the shared folder, to no avail
  6. Moving the file to the desktop seems to allow access; moving back encounters the same issues
  7. This is happening on two different servers (Windows 2008 R2 and Windows 2003 and on two different domains

We are planning a server restart tonight when users stop working, but can't think of anything else that could be the cause of the issue.

We are getting the "Access Denied.  Contact your Administrator" message with the files that can't be opened.

FTP server requires credentials - but all credentials are wrong

I have set up an FTP server with FTP site on Windows Server 2012, allowed anonymous on sever (in IIS) and at site level. When I try to access the FTP site the server askes for credentials, even though I allowed anonymous. Whichever credentials I add, when prompted are rejected as wrong, even the admin account. I've tried this several times with different accounts and double checked that the credentials are in fact not wrong, but the browser doesn't accept it and tools like FileZilla and SmartFTP says explicitly"wrong password" (even when I access as anonymous). Why would this be?

EDIT: It doesn't matter whether I allow anonymous or not, I've tried all variations, but I always end up here: I'm asked for credentials, and the credentials are wrong (not not accepted, but wrong password or user name.)

Storage Spaces: Rebuild Problems (Detached Virtual Disks)

October 12, 2015, 11:52 am

Today I moved my physical disks to a new enclosure. The Pool is made from 10 harddisks and 6 SSDs.

(One HDD was a hotspare, all virtual disks are either 3Copies/2Columns or 2Copies/3Columns disks)

Two "Errors" happened during the migration:

- First, I dropped one of the SSDs on the ground
- Second, I didn't connect 3 of the SAS-Cables properly.

When the server was started, Storage Spaces noted that 2 SSDs and 6 HDDs where missing, set them ALL to retired and enabled the HDD-Hotspare.

No rebuild was going on, because obviously you cannot recover from only 2 HDDs containing data.

So, I shutdown the machine, fixed the SAS-Connections and started again.

After Setting the Disks back to "Automatic" Usage (they have been detected properly now) I could not repair anything, because the SSD dropped to ground was not found anymore.

So, I grabbed an older, smaller (but sufficent) SSD to replace the broken one. After using powershell to retire the missing SSD, invoke a Disk-Repair i'm now facing the following Situation:

The HDD-Tier seems "healty" again. However, some Virtual Disks are now reporting a "detached" state rahter than "degraded" or "incomplete" - The disks that have been reported "degraded" or "incomplete" are now "ok" again after running the repair.

Usually every SSD showed 53,3 GB of usage. After the repair, the "new one" only contains 22,5 GB of data and the retired one still Shows 31 GB of data. (It Looks like the content of the detached disks has not been repaired?!)

I'm unable to remove the retired physical disk. ("Still in use" Server Manager claims)
I'm unable to "attach" the detached virtual disks to the Server in order to re-run the repair command. (tried the Manual-Attach-$False-Powershell Thing as well as every UI-Option)
Error just says "Error attaching Virutal Disk: Failed to attach virtual disk. Failed"

5 out of 12 disks ended up "detached" - how can I attach / repair / recover these disks?
Since everything is either double- or triple mirrored, a single SSD-Failure should not be able to harm any virtual disk?!

Feel free to come with everything that's in your mind - I've played all cards on hand...

Very Same Situation reported here:
https://community.spiceworks.com/topic/901742-storage-spaces-1-failed-hard-drive-causes-mirror-to-crash

The hotfix mentioned there is only for 2012, not 2012 R2 - cannot install :(

fsrm not reporting accurately

October 10, 2015, 2:24 pm

We have two Windows 2012 R2 servers that are DFS servers. We use DFS to replicate users documents folder so that it's highly available. We have deduplication enabled on the specific volume. I've installed FSRM and I've run some reporting specifically to find out how much space is used by people storing mp3's and other audio files. I don't think the report is returning accurate information. I've done a search on the drive redirecting output to a text file and there are thousands and thousands of mp3's. When I run the report in fsrm in doesn't return the same amount of data. I calculate there is probably 100GB's of music files on the share and the report only returns 12GB's.  Same with wma files.  I know a specific user has 6GB's of wma files and when I run the report it doesn't return that user as having any of those files. What could be the issue of fsrm not returning accurate information?

DFS Namespace Availability

October 13, 2015, 2:50 am

Hi,

I hope you don't mind but I have a couple of questions regarding DFS. I am in the process of configuring DFS where I work to replace the generic file server set up we have. We have two sites that are on the same domain, eventually we'll have a DFS server in each location. I'm almost there, at the moment I have two servers configured with DFSN/R, I have replication between the two servers. Both servers are configured in the namespace, referral statuses are enabled, I have edited the referral ordering so they are first and last among all targets, both are members of the replication group.

The issue I'm having at the moment is when I take down the first target the namespace is no longer available, in order to work on any files or folders I have to navigate to \\server-name\company-docs

Firstly, does anyone know how I can provide a highly available namespace so that if the link between the two sites fails, users at each site will still be able to reach files and folders via \\domain-name\company-docs instead of having to revert back to \\server-name\company-docs?

Secondly, can I configure DFS so that users at each site connect to the DFS server on that site?, as I think because they are both in the same domain they will both have the same cost.

Thanks in advance.

Store Shadow Copies on Different Volume

Hi,


I want to store shadow copies of volume "U:" on volume "S:", but shadow copies settings menu only lists the volume selected (in this case "U:") as a Storage area location.

I've tried enabling and disabling the shadow copies to clear past restore points if there were any, I also formatted volume "S:".


Both Volumes are part of the same disk, and the disk is assigned to a File server failover cluster.

Servers running as virtual machines Windows 2012 R2 (VMware 5.5), and the Disk is added as an RDM disk.


I'd like to avoid combining the volumes as a last resort, any other suggestions?

Thanks.
