Handling updates on a SOFS using RDS 2012R2 and deduplication

So we are using RDS 2012R2 with well over 100 Personal VMs. The data sits on a Scale Out File Server that is deduplicated. Everything is good except on patch day. I am currently sitting around 45% free with my space but on patch day i dip very low. The more/bigger the patches the closer to 0% i get. It then dedupes out and i am back to the 45% range. What is Microsofts recommendation to handle this huge patch dip?

RDMA & Multichassis Link Aggregation (MLAG)

April 27, 2015, 12:52 pm

Hello everybody,

I am implementing a Scale-out file server together with Hyper-v, both clusters have been equipped with Chelsio nics which have been placed in different VLANs (to enable SMB multichannel). I ran some file copy between these systems in order to see how RDMA is working and I have observed some strange and inconsistent behaviours. I was expecting to see the same speed when moving files between systems that shares the same network infrastructure (all servers are connected to the same switches) and that mount the RDMA nics.

The network team implemented MLAG on the switches on which the RDMA nics are connected.

I just wondered if the implementation of MLAG could potentially interfere with the proper operation of the SMB 3.x ? 

The behaviours that I have observed can be summarized as:

File copy between the Hv hosts - I manage to achieve a speed of 1.5 GB/s, but during this process the speed fall down (almost to 0 MB/s) for two times. it seems that I have reach a bottleneck or some hard limit.

File copy between the FS cluster node - I managed to achieve a speed of 600 MB/s, but at 1/3 of the copy the speed is reduced to 135 MB/s without been able to recover to the 600 MB/s.

File copy between the Hv hosts and FS - I managed to achieve a speed of 600 MB/s.

Thank you for the help J

I use the following robocopy command to copy files from old to a new server:

@ECHO OFF

SET _source=d:\data\
SET _dest=\\newserver\DATA\

SET _what=/COPYALL /ZB /secfix /SEC /MIR

SET _options=/R:0 /W:0 /LOG:C:\MyLogfile.txt 

ROBOCOPY %_source% %_dest% %_what% %_options%

How can i change this command to only log changes new files and directories.  Right now is logging everything.

Thanks

Hello,

Our previous file server died, the data was recovered and placed on a sun server. Now I have deployed a new file share server win 2008 R2 and need to move/copy the files/data to the new server. In the past I have used SyncToy for desktop, is there something similar for server 2008?

Please let me know ASAP please since I need to move the data back.

Thanks,

folder redirection directory change

hello,

i am an ict technician at a school in belgium.
i have a problem with folder redirection, orginaly the folder redirection was configured for SOME of the users f.e:
my document to \\dc1\homedir\%username%\my documents

now the following problem , my dc1 storage was not enough to keep up with the place of the documents etc

2 weeks ago all of my users have folder redirection to \\dc2\homedir\%username%\my documents.
for the "new users" that didnt used the dc1 before is their no problem but for the users that did use the dc1 is their a problem.
the sync center doesnt remove the \\dc1 location and gives conflicts.
the sync center gives the following locations : \\dc1 and \\dc2.
also when they create a word document and save it under my documents they somethimes get an error, file corrupted or path unfindable. or when they download something it sais u dont have the rights to open while they just downloaded it.
also somethimes f.e they get no icons on the desktop or on the start menu they are just white icons.

the only option i know for now is to delete the user profile on the local pc , log in again.
the user get an temp. account, i log in to my admin again and delete the .bak from the registry
log in again with the new user and the sync center is allright.
also theirs no more problem with word or what so ever.
but this is insane because we have allot of users and allot of pc's its almost impossible to go from pc to pc to remove the users.

thanks in advance !

greeting

Hi

We have 2 windows 2008R2 servers in our DFS.  It is a mesh replication setup.

We tried adding a 3rd one by first pre-seeding the data.  However after adding the new server to the existing replication group; a bunch of files/folders got zapped and ended up in conflictanddeleted folder.  That is so stupid!

Any explanation?  I can't find anything useful in the eventlogs on why in the world such thing can happen!

Move DFS replicated folder Server 2012

Hi,

 I have 2 Windows 2012 R2 servers in the same DC, one server has a 6 TB disk and the other has a 5TB disk. One server has 300 GB free and the other has 8 GB free, I'm seeing disk IO problems, as well as backup issues trying to backup several TBs on a single volume.

The two servers are members of DFS replication groups for various shared folders with satellite offices. Replication has been a little problematic - lots of 4202 errors in the event logs, with backlogged files building up.

Im also aware that having a single volume limits DFSR to use a single DB for all my RFs, which isn't best practice. What I would like to know is what's the correct procedure to introduce a new file volume and move some of the existing data on to the volumes to get around the issues above?

Thanks

File Server loses all it's shares and becomes unavailable

We have problems with a Windows Server 2008 R2 File Server. At random the file server loses all it's shares and the homedrive and application shares are not available anymore. A reboot seems the only way to solve this, untill it happens again. Today we had another crash and we were able to create a manual dump of the Server service. I have used WinDBG to analyze the dump, but I'm not really confident what I can use from this dump. Here is a copy of the dump:

DFSR stopped working, UpdateState = Blocked ?

Hi!

I have a weird problem, our DFSR have stopped working on one of our servers. We have seven remote2008 R2 file servers that is synchronizing to one Server 2012 R2 server à la Hub and Spoke.

I ran Get-DFSRState and saw that many files had the updatestate Blocked. So I ran this command:

Get-DfsrState | ? SourceComputerName -Match TheServerThatIsFailing01 | Group-Object updatestate

Count Name                      Group
----- ----                      -----
  144 Waiting                   {Microsoft.DistributedFileSystemReplication.DfsrUpdate, Microsoft.DistributedFileSystemReplication.DfsrUpdate, Microsoft.Distribute...
  267 Scheduled                 {Microsoft.DistributedFileSystemReplication.DfsrUpdate, Microsoft.DistributedFileSystemReplication.DfsrUpdate, Microsoft.Distribute...
  345 Blocked                   {Microsoft.DistributedFileSystemReplication.DfsrUpdate, Microsoft.DistributedFileSystemReplication.DfsrUpdate, Microsoft.Distribute...

I have no idea how to troubleshoot, there's free disk space available, no errors in event viewer.

Does any one know what blocked means? How do i troubleshoot ?

Thanks!

If I attempt from the GUI, nothing happens.  I did give myself FC permissions to the SysVol folder.  I even tried drilling a few folders down using the GUI and same thing, nothing happens.

Windows 2012 File Cluster Deduplication Issue (Garbarge Collection not working)

Hi

I have a 2 node Windows 2012 Standard File Cluster with 5 cluster roles.  I have about 250TB of storage present to the cluster split down into lots of smaller sizes.  One of my colleagues enabled Data deduplication on one of the drives, the drive in question is 30TB in size.  Something happen over a course of 48 Hours and used up all the free space.

My problem is I have moved around 1TB data of the drive to another Drive but windows is still reports there is no disk space.

I have run the following command from powershell but it has not helped. 

"start-dedupjob -volume <DriveLetter> -Type GarbageCollection -Full" and "start-dedupjob -volume <DriveLetter> -Type GarbageCollection -Full -Priority High".  Both times I can see the job has been scheduled and is running with "Get-dedupjob" but the job just sites at 0% progress, I have left the job to run for 5 hours and still no change in the progress and no disk space reclaimed.

I have read on another forum to turn off Deduplication and then run the Garbagecollection again but when I turn off deduplication within seconds it has been re-enabled, almost like it does not turn it off.

This is a major issue for me and if anyone can help that would be grate.

i mean explicitly not labs / homes but something you roll in the office you don't own yourself :)

would you put into production some free solution with allowed commercial use (no eula violation! ) but with community only / limited vendor support? 

what would be a game changer for you? say going freenas (free) -> truenas (paid) upgrade?

DFSR Alternatives

Hey all,

I have a fairly large DFSR implementation in which I think I am pushing the limits. I have already passed the recommended limits and am now pushing roughly 8 TB per set of servers and over 10 million files. I have 9 of these so its like 72 TB. I was wondering if anyone has any better more robust solutions or if I just need to add more sets of DFSR servers to spread the data out more.

Here's what I need from a solution which are all included in DFSR: ( a full appliance style hardware solution

1. A distributed Namespace - i.e. one virtual name can point to multiple servers\share on the back side.

2. Two way replication, real time (or close to it)

3. Ability to prioritize where the user load goes and be able to move the users around on the back side.

4. Ability for users to connect to any of the machines in the namespace (i.e. not read only, nearline, or offline)

Thanks in advance

Life moves pretty fast. If you don't stop and look around once in a while, you could miss it.

iCACLS question

Using Windows 2012 R2 I am trying to understand iCACLS command to fix permissions on a folder. 

Default permissions using iCACLS looks like:

NT AUTHORITY\SYSTEM:(F)
NT AUTHORITY\SYSTEM:(OI)(CI)(IO)(F)

Looking at permissions in the GUI from the advanced dialog, SYSTEM account has full permissions. There are other ACE entries for other accounts but only the single entry for SYSTEM account. 

When I attempt to reproduce the first ACE setting for SYSTEM permission using iCACLS or GUI and it comes out as:

NT AUTHORITY\SYSTEM:(OI)(CI)(IO)(F)

What is the additional ACE seen in iCACLS and how do i reproduce this?
