comment How do I get a user id (uid) on ESXi 5.x via ssh?
@Tal I have no clue. I've never needed to do such a thing. Busybox is a very minimalist distribution of Linux. The fact that you're having issues with this indicates that there's probably a more elegant solution to your problem. Can you tell us what your end goal is? Why are you distributing SSH keys to ESXi hosts, for instance?

You probably shouldn't be distributing ssh keys to your ESXi hosts either.

You shouldn't need to change file ownership in ESXi either. These are normal actions. Can you outline your real problem?

Why do you need this? I can't think of any reason why this would be necessary.

This is in response to your question about open-source implementations..

comment fastest way to transfer small files (faster than scp)
Good answer to a crappy question. This has definitely been answered a few times here. I've been using tools that leverage UDT to provide WAN acceleration more efficient transfers over high-speed/high-latency links (or short distances with lots of small files)...

comment Alternative file system/volume manager for ZFS w/ non-ECC RAM?
You don't have an option to just use a system with ECC RAM? It's a pretty low barrier to meet. If you want ZFS, use quality hardware.

comment fastest way to transfer small files (faster than scp)
Where are you copying from and to? Distance between locations? Connection speed? Source and target server specifications? Number of files? Size of files?

comment Detecting duplicate IP address from improperly cloned virtual machines
It shouldn't happen. You shouldn't be having "bad clones". It's irresponsible and sloppy to create VM clones without at least changing the IP address or computer name. The SID can be the same, unless you're cloning domain controllers... but then, you shouldn't be cloning domain controllers :) - Try to focus on correcting the process and the root cause instead of fixing the symptom.

comment vCenter is hosed, and I want to setup a VCSA server
@HopelessN00b When I ran into too many problems with the Windows-based vCenter, I converted to the appliance. It's been much better since, and VMware is really pushing people in that direction. I don't advocate the Windows vCenter for new installs.

comment Disabling cache on ZFSonLinux
This is beyond the scope of this question. The answer is: it depends.

comment Disabling cache on ZFSonLinux
@Devon logbufs is for XFS. You have a battery-backed write cache on your RAID controller. It's fine to use "nobarrier".

comment Disabling cache on ZFSonLinux
@Devon I don't use ext4 on top of ZFS. I use XFS, though. I haven't had any abnormal signs of overhead. Are you mounting your filesystems with nobarrier, or if using RHEL/CentOS, using the tuned-adm enterprise-storage profile?
