VM Converter – FAILED: A general system error occurred: The file is too big for the filesystem

Jason Tramer Jason Tramer Profile: Jason Tramer

I recently got this error while trying to P2V a server. The reason? On default settings when setting up a VMFS volume (block size 1) the maximum size of a virtual disk is 256 GB’s.

Now what can you do to fix this? Well sad answer is you can reformat you VMFS volume with a different block size.

Block size Max Virtual Disk size
1 256 GB
2 512 GB
4 1024 GB
8 2048 GB

If that isn’t something you care to do then keep in mind by default VM Converter will take the maximum size of each volume on your physical server (c,d,e, etc) and lump them all into one physical disks. You can however go into the settings and create a virtual disk for each volume (something I recommend doing regardless). You can also adjust the size of the target virtual disk to eliminate free space, IE if your D drive is 325 GB but has 80 GB free then by default it will try to create a 325 GB virtual disk (and fail) but you can adjust the virtual disk size down to 245 GB.

Hope this helps

Switching VM’s over to a different Virtual Center breaks connection between BES and Exchange server

Jason Tramer Jason Tramer Profile: Jason Tramer

We had an issue with our BES server stop working properly. Some mail was getting to users but there were errors sending mail and we couldn’t activate any new users.

Here was the error when trying to activate.

{e} MAPIMailbox::MAPIMailbox(2) – OpenMsgStore (0x8004011d) failed

A reboot of the exchange server followed by a reboot of the BES server fixed the issues but we weren’t sure if this was a coincidence or caused by switching the VM’s over to a different Virtual Center server

Shortly after that we moved over a different set of Exchange server and BES servers and the exact same issue occurred.

Be aware!

Blackberry comes up with Enterprise Activation error on startup

Jason Tramer Jason Tramer Profile: Jason Tramer

This Blackberry was activated on the BES and worked fine but every time the blackberry booted it came up with an activation error.

I wiped the blackberry and purged/re-added the user to the BES but it would not re-activate. I then purged the user and used the blackberry handheld cleanup utility on the BES server and that fixed the issue.

ASA 5520 not Nat’ing traffic

Jason Tramer Jason Tramer Profile: Jason Tramer

A colleague of mine and I were setting up and configuring an ASA 5520. We ran through the basic setup wizard and set up the preliminary NAT and access rules and found we could get out to the Internet. The ASA itself could access Internet resources but we on the inside connection could not. So of course we double checked out NAT rules and ACL and everything looked fine. So we figured it was a bug and did a factory default reset and still had the same issue. After the second factory-default reset we were ready to chalk it up to hardware issues when we decided to do one more factory-default reset and that fixed the problem. I am unsure what change on the third reset that didn’t on the first two but since then the device has been working fine.

Cisco ASA – Remote Access VPN not getting reserved address from DHCP

Jason Tramer Jason Tramer Profile: Jason Tramer

I have configured a Cisco ASA 5520 in an environment where the remote users need to get statically assigned IP addresses. In the past this was done by using MAC address reservations on the DHCP server. In replacing their old firewall and putting in the ASA what I have found is that even though Remote Access VPN is configured to assign IP address’s via the DHCP server and even though that works (You can see the lease on the DHCP server), it does not give them the address that has been reserved by their MAC address. Does anyone know a solution to this? I would love to hear it.

SQL server not deleting files as part of Database Maintenance Plan

Jason Tramer Jason Tramer Profile: Jason Tramer

I have actually seen this issue now twice in a two week span at different clients with the same resolution so either it’s a common issue or it’s just a coincidence. In this scenario the database maintenance plan is set to delete old backup jobs, the job completes but the files are not deleted. In both cases the fix was simple, in the plan it asks you to specify the file extention it should delete which in most cases is bak. Make sure when you are entering this yyou enter JUST bak, not .bak or “bak” or anything else. If you have any charachters (including spaces) other than just the letters bak it will not work.

Hope this helps you

Using a POP connector when migrating to from POP to Exchange

Jason Tramer Jason Tramer Profile: Jason Tramer

When focussing on the SMB (Small-Medium Business) market I find that alot of companies don’t yet have their own Exchange servers and are still using POP mail. With the age of virtual servers upon us it is easier then ever to sell them on Exchange when you are already selling them a physical server and Windows enterprise license.

Best practice I have found when doing the migration is to use a POP connector on your Exchange server. This allows for a gradual migration and eliminates any lost email during the time when you are changing over the MX records.

Microsoft includes a free POP connector with Windows Server 2003 SBS and yet for some unknown reason doesn’t include one with the real version of Exchange. Still, using SBS is in fact it’s own punishment so it’s not a huge loss.

I recommend the Exchange Connector product by Quantum Software Solutions. It’s really straight forward to use and very customizable. You get a 30 day free trial, which is all you need if you are only using it for migration purposes, though I think it is well worth paying for if you think you are going to use it on a ongoing basis.

HP ProLiant is Highest Performing Server in Latest VMmark Comparison

Check out the results here:

The HP servers scored the highest performance results when running VMware in comparison to multiple other vendors including Dell and IBM. Certainly some food for thought when purchasing your next physical server.

I have been troubleshooting a BES issue with a user whose email isn’t syncing properly. Some email sync’s fine and others not at all. I found this useful article that explains it really well.

Migrating DNS records

Jason Tramer Jason Tramer Profile: Jason Tramer

I am really tired of the way some people handle DNS record changes. It’s like people (even people in the IT industry) don’t seem to realize that changes are not instant. It takes on average between 24-48 hours for any record changes to propagate across the Internet and yet you have DNS cowboys trying to cut-over records and then wonder why names aren’t resolving, or mail isn’t flowing.

Best rule of thumb I have seen is maneuver your record change in a way that for that 24-48 hour period either record will work, if you can’t do that at least make your change on Friday before you head to the pub and make sure everyone knows that things may not work properly during the weekend.
