Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

I am trying to make a replacement storage spaces direct cluster on server 2019 to replace our 2016 cluster.  But I have an issue after creating the SET switch and creating hyper-v virtual NICs tied to the SET switch it only displays the virtual NICs speed at 10gb I am using one dual port card on each node.  On the 2016 cluster the virtual mic shows 20gb.  Am I missing something on the 2019 cluster? Should the virtual NICs so the aggregated bandwidth of the physical NICs the the SET switch is connected to?

I have a PowerEdge T610 with a Perc 6/i Integrated controller. when i look at it in Open Manage i can find the predictive failure drive and have i identified it by enable blinking on the drive. but i can't tell if it is a RAID level drive so i can replace it without shutting down the server? OpenManage shows 2 connector(s) the first Connector 0 RAID has 4 drives 0:0:0:0, 0:0:0:1, 0:0:0:2 and 0:0:0:3 all on line and good status. the other connector, Connector 1 RAID only shows 1 drive ID: 1:0:4 Physical Disk: Status show Non-Critical.  Drive details below. what i am trying to figure out is, is the drive part of a RAID array? Seem odd to have 1 drive sitting by itself not as part of a RAID.  Also, what data is on this specific drive?
in the OS Disk Manager is shows.

VMWare Storage: VM using 4.7Tb when disks add up to 2.8Tb and there are no Snapshots. How can I find out what is using the extra disk space?
VMware Version 6.0

The VM has 5 disks total of 2.8Tb No snapshots

Used Storage 4.77Tb

Why is this so high is there some orphaned disks?

We have a 3 node cluster with shared storage, SV1, 2, and 3.

Our issue started when we were getting RPC errors when trying to connect to the cluster in failover cluster manager and other nodes hyper-v. Error is below:

"Cannot connect to the RPC service on computer "SV1". Make sure your RPC service is running."

It turned out that this issue was because the domain admin password had expired, once we changed it and logged off/on on all of the nodes the problem was fixed.


_______________________________________


Now, when we are on SV1 we cannot create any gen. 2 VM's, but we can create gen. 1. On SV2, and 3 we are not noticing any problem. Also, we are able to create the VM if we add the ISO afterwards.

I don't think it is a problem with the storage location or the actual ISO because we are grabbing the same ISO and creating a vm no problem on the other two nodes.

Attached is the error we get when attempt to create the gen.2 VM.
Error when creating win10 VM on SV1

We also get error event [14026] in event viewer under the hyper-v server roles in custom views. Details below:



"The description for Event ID 14026 from source Microsoft-Windows-Hyper-V-VMMS cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

I'm stumped by an extremely slow backup process on one of 8 virtual machines that are all being backed up using the same process.  Here are the particulars:

HP ProLiant ML350 G9 server with ESXi 6.7U3 (HP custom image) standalone installation; 2 Xeon E5-2609 CPUs; 80GB memory; @7TB of provisioned internal storage (RAID5).
There are two NAS's connected to this server; one NAS has 16TB of storage that is used for backups ONLY; the other one has 6TB of storage used for virtual disks attached to several different VMs.
There are 4 VMs on this host machine, 3 of which are backed up to the backup NAS. All of the VMs are running Windows Server 2019.

The VM that is causing the problem backups is provisioned with 6TB of file storage; a 4.5TB vmdk on the internal datastore and a 2TB vmdk on the storage NAS.  All of the VMs on this server as well as 5 VMs on another standalone ESXi 6.7U3 server are backed up to the backup NAS using one of the VMs running Veritas Backup Exec 20.4.

The problem appears to be only (or at least primarily) the 4.5TB VMDK that is on the internal storage of this server.  It is so slow that it's taking upwards of 5-6 DAYS to back up the contents of this one virtual disk.  Formerly when this data was on another host machine (an older machine running ESXi 5.5 and using Backup Exec 15) the backups would run at about 1-3GB of data/sec and take about 2-3 days to back up the entire virtual machine, plus 2 other smaller VMs, and duplicate the backup to an …

I have encrypted the volume using luks in centOS 6.3.
And generated the key added to the volume.
I have also added the entry in the /etc/crypttab for the encrypted volumes. As the volumes are from storage it takes more time for the server to reboot, so i have commented the /etc/crypttab entries to boot faster.

I Ubuntu I am am able to decrypt the volume using cryptdisks_start and in centOS 7 I use systemd-cryptsetup@<name>

Where as in CentOS 6.3 I am not able to find both the above commands.

My requirement is to boot decrypt the volume after the server boot's using a command like cryptdisks_start or systemd-cryptsetup@<name> .

Openstack swift issue.  I have all nodes running Ubuntu 16.04.4 LTS.  I have one controller node and 4 swift storage nodes.  All of the storage nodes have 1 boot drive and 3 data drives.  The first storage node works just fine.  However, it filled.  Upon which I realized the other 3 nodes are not working correctly.  It appears that the "boot" drive on the other 3 nodes is full.  However, I cannot find where the space is taken from.  The three data drives are mounted off of /srv/node/sda, /srv/node/sdc, and /srv/node/sdd (as described in the OpenStack documenation).  If I unmount them, I am still able to access those paths and see the contents.  So, it is saving the data to local disk and not the mounted disks???

Any help would be appreciated.

Hi I have two VNX5500,

I have created a storage pool "pool 0" and expanded it to 10TB.

There is no data on it but it has 3TB used by 18 Virtual Disks which I can see under private luns.

I want to delete the pool but cannot delete it directly or delete the 18 virtual disks.

Any idea how I can do this?

I have checked and I cannot see and mirrors, san copies or snapshots associated with it.

I am setting up a 3-node Windows failover cluster using HP dl360’s with emulogic SM1200e card to handle MPIO connecting over fc to an IBM v5000 SAN. all were configured together, click for click. when I went to test the failover, nodes 1 and 3 copied files with no disruption at all. when I pulled the fo cable on the first connection for node two, MPIO stopped copying for 30 seconds before resuming without replugging the cable. I moved the fiber to different ports on the SAN but the problem followed the port on the hypervisor- same behavior regardless of which SAN ports I used. in case this is not clear I am assuming the problem lies with the second connection that I did not pull on the node 2. pulling the other cable on this node worked just like the other connections with no disruption. so I assume no issue with the San or server just the card. any idea how to find out why it waits 30 seconds before switching paths?

How might I move these files into a dropbox? The computer has two drives, c and d. It has been working slowly for a year now and I'm just now trying to transfer all the files so I can wipe the drive. I did try doing that without deleting personal files and it didn't fix it. 20190927_123129.jpg There are multiple files that give me this error message, all different types so im not sure what the common factor is. I have tried using the command prompt to try to find the original source but it did not work. I tried looking it up online and tried some of those suggestions but again, the command prompt did not turn anything up. Thanks for the help.

I have a Lenovo P520c with 3 HD's and I want to RAID the drives. I have Intel Rapid Storage installed, I went into the UEFI and changed it from AHCI to RAID. How ever when I do that the PC wont boot and there is a warning on that setting stating changing it may cause it not to boot. My question is there a way I can get this RAID built out without blowing away the OS and rebuilding it?

Hi, I've noticed all our access switch interfce LEDs blinking rapidly which suggests there's a broadcast storm going on, the switches are all Cisco and mainly 2960X, there are two stacks formed with 4 switches each and three other standalone access switches together with six storage and server switches.

Any ideas on the best way to analyse and identify the cause (without disconnecting cables as this is a live environment).

Thanks.

Hi there, im at a loss as well as my developers. We are having a new CRM created within Dynamics 365.
Without going into the whole CRM and what it does, we have an area under each client account where documents are uploaded.

The problem we have with the storage of the agreements and contracts. Dynamics storage is expensive, but the main problem we have been told about but the developers is the files will be secure to the to owner of the client account but other members who are invited as sub members will apprently not be able to view these files.

The original suggestion which does work is to use a Sharepoint site. This technically does work but it does open the risk to allow anyone who may stumble across the sharepoint site to access the storage and see the files.

I did come across an article that suggested Dynamics coulod be integrate with a solution like Azure Blob, but my devlopers are not aware of this solution and again im not sure how close to keeping the files secure from users who shouldn’t have access

This is the article i found https://community.dynamics.com/crm/b/dynamicscrmbestpractices/posts/alternatives-of-document-storage-in-dynamics-crm


So my main questions is regarding finding a solution that will allow us to store these files for each account, atthe same time limiting access to these files to the account owner and the sub members.

Is there a way using APIs etc??

Thanks

Queries regarding Content Library in v Sphere 6.5..

What if We have multiple DC for multiple location managed by single DC ?
Will there be any bandwidth issue if we use single centralized content library?
Data store used for Content library must be accessed by all Host running from different DC/Locations ?
 
Will there be any impact if use single centralize content library as earlier image files were there @diff Data store configured at different locations

Dell PowerEdge T320 H310 RAID controller does not recognize all physical drives?
I have two identical T320 servers with Perc H310 controller. I'm trying to add an additional RAID 1 virtual drive for data partition. I purchased compatible drives for this server and installed then. When I enter the controller BIOS I only see drives 0,1 and 3 don't see drive 2. Both servers are giving me the same result. I thought it may have been a defective drive but I was able to eliminate that theory. I have updated both servers to the lasts BIOS, iDrac and controller firmware's. Any thoughts?

Some time ago we migrated some databases from SQL Server 2012 running on Windows Server 2008 R2 (Databases are in an Availability Group) to SQL Server 2016 running on Windows Server 2016.

The new server is running on All-Flash storage.

There are a pair of web servers running a web application, these servers are Windows Server 2016 and it is a PHP web application running in IIS.

Since migrating there has been a noticable reduction in page load times, particularly when saving data.

Typically it was < 5 seconds, but now has increased to >10 seconds.

We use ExtraHop to monitor our wire data and can see that round trip times to the DB servers is <100ms, however the application executes a significant amount of queries per save operation, so the comulative effect could be a part to play in the performance issues.

We have disabled Anti-Virus, but this had no effect.

What would be the suggested places to look to try and identify where the bottleneck is?

Hi,

The below one is rough from actual one.  If I call only T2, application works fine. When I call T1 and then T2, then fuse_main fails with /dev/fuse already mounted as per /etc/mtab.

Here, I am surprised, how  T1 thread affects T2 thread. What could be the reason.

void*  someworkerfn()
{
     //some logic
}

void* call_fuse_main()
{
     //prepare agrs (-s,-f,-o,allow_other...)
    //fuse_main
}

int main()
{
      pthread_create(id1, NULL,someworkerfn,NULL);  //joinable thread-T1
      pthread_create(id1, NULL,call_fuse_main,NULL); //joinable thread-T2

      return 0;
}

Thanks,
bvm

We have Dell r730 running Solaris 11 and MD1420 storage array connected through perc h830 raid controller. MegaCli is unable to collect disk information.

The command is /MegaCli -PdList -a0

and the error we get is:
ERROR:Could not detect controller.
Failed to get ControllerId List.
Failed to get CpController object.

Any suggestions? Is there a different software that can be used under Solaris 11. Mainly we are trying to check disk status every few hours through cron job, so that any disk failure can be notified through email in a timely manner.

Similar hardware running Solaris 10 x86 works fine.

/MegaCli -PdList -a0 | grep -i "Firmware state"
Firmware state: Online, Spun Up

We have a PowerEdge R410 with a PERC S300 Raid Controller.  We had an issue with one of the drives not being recognized by the Raid controller, so we decided to rebuild the RAID and reinstall Windows.  The RAID appears to be set up fine in the card, but no OS installation is able to detect it.  We've tried Windows 2012 R2, Windows Server 2016 and Linux, but none can see the virtual drive.  Any suggestions??
