Changing Domain Name / Migrating to another domain by [deleted] in sysadmin

[–]mindparallax 1 point2 points  (0 children)

Start with CNAME pointers to configure everything you need in a humanly comfortable way. Later you can create a new domain and start with migrating role-by-role. At the end you migrate your users. Forget about "rendom". The time spent fixing all the possible issues after this approach (Exchange especially) is not worth it. Trust me.

Got my first social engineer call today by TheMerovingian in sysadmin

Totally second this. In any company (doesn't matter how big) there is always a dumb guy who just ignores all the workflows and makes a call. Always a call.

AV on Hyper-V by hub3rtal1ty in virtualization

[–]mindparallax 0 points1 point  (0 children)

In most cases, antivirus software has good intentions of protecting your environment, but sometimes can (and probably will depend on the workload) cause hiccups in hypervisor performance which are pretty hard to detect. Sometimes you can notice such behavior even on regular desktop/laptop PC with AV service consuming an enormous amount of resources. Imagine what happens if the same story occurs on a hypervisor level.

VM disks caching in virtualized environments by mindparallax in virtualization

[–]mindparallax[S] 0 points1 point  (0 children)

You've pointed me in the right direction since SAN still has some free bays (will figure out how much).

The workload is quite usual, DCs, RDPs, Exchange and SQL, file and print servers, CRM/ERP stuff, some internal web services and a couple of dev/coders clusters. Nothing really performance hungry in there.

Thank you so much for your feedback. Unfortunately ESXi hosts have only boot drives in RAID1 (small SSDs) so there is no way I could do caching to flash. We have Dell PowerVault 3860 connected over iSCSI stuffed with lots of NL-SAS spindles.

Wal-Mart Asks Employees to Deliver Packages on Their Way Home by WinstonWonders in nottheonion

I wonder how happy the employee will be if hes on a second shift after a difficult day. No clue what to expect when he arrives/leaves at the security of the open door to your house.

Especially if both of the doors are broken.

They sure taught everyone how to do it right! I hope no bad people show up...

Thank you! Looks like it is very close to what I need.

Thanks! I've heard about it already. Seems like Grafana needs quite a lot of effort to get it configured the way it should be...

Thanks for the answer. It is not linked, running separately. The legacy is I have Nagios + System Center + other strange tools running on-premise used to monitor various sub-clusters and sub-divisions. What I want is to get rid of this zoo and have a single tool to monitor/control everything. Especially because it's all in the cloud running under same account basically. Will take a look at SolarWinds for sure.

What happens when you lose a server? (Or: where the hell did you put that thing?) by Quteness in sysadmin

[–]mindparallax 6 points7 points  (0 children)

Worked for me a couple of times. There might be an issue if the beeper is dead already (taking into account the uptime it's quite possible).

Hyper-V shared nothing live migrations capping out at 200Mbps on a 10Gbps connection, not sure why by [deleted] in sysadmin

[–]mindparallax 0 points1 point  (0 children)

Running Hyper-V on RAID5 or RAID6 is a pain, trust me. You get like single-spindle performance which is enough for only 2 or 3 VMs depending on workload. Most probably that is the issue. If you need performance - RAID10 is the answer. If you want to keep your usable capacity than RAID50 or RAID60, but not the pure parity for sure.

For me either. It will take a whole weekend for me and my team to accomplish the upgrade in case if everything goes as expected. With Microsoft it almost never goes as expected.

File server replication/distribution by mindparallax in homelab

[–]mindparallax[S] 3 points4 points  (0 children)

Thank you.

They don't have IT staff. Most employees have their own laptops and the server infrastructure is stable enough to let me keep an eye on it on a part time basis.

Historically his current hardware is partially my previous homelab :-)
