Partitionning Disk for OS X Server 10.5.4 - A good Idea?
Hi,
Is it a good idea to partition the Disk for a clean install of OS X Server (10.5) to put the system on one partition and other files (datas of groups and users) into the second partition?
If yes, please what size of partition should I consider for OS X Server to breathe freely?
TIA
If you cant get another drive in there (highly recommended) then yes I'd recommend that.
The problem is, the system keeps some data on the system partition (mail, for example is stored in /var/spool/imap) so if you truly want to separate the data you will need to move this folder (with the mail server off) and change the setting.
Id say about 20GB would be reasonable, that is enough for the system and anything you might add to it, and plenty for things like the collaboration tools which use so little space as to be not worth moving.
Whatever you do, backup your stuff. Even if its just Time Machine (which in my experience is better than nothing, even in the 'advanced' setup)
Does that help?

SSD or spinning disk for Mac Mini server?
I'm using a Mac Mini 2cd as a media server (operating over wifi), and the hard drive is dying - I'm going to replace it, and was thinking of an ssd (the os is on this drive, the media is on a large external). Would this provide any real world speed increases?
Thanks!I would just run with a standard hard drive then they are much cheaper. You can get a 1TB for about $84
I have an old G4 Xserve that I use to use for that. But, it is just sitting somewhere collecting dust now. -
Using OS X Server to host Wordpress site, good idea?
I have a 2009 Mac Pro. If I installed OS X Server to one of my HDD partitions, does OS X Server come with all the app's for me to host my Wordpress blog? I've already bought a domain name. I know it's more reliable (much better uptime if I bought cloud hosting), but at this moment it's just a casual blog. If my Mac Pro went to sleep would the blog/website go down? If yes, that's not a problem, but just want to know. I also think it would be fun to see if I can set up a blog/website and host myself.
But I read I need a static IP address for this to work? If yes, that means all the small businesses for which OS X Server is marketed to, need to buy a static IP address which I heard is expensive.
I also heard that hosting is dangerous as my Mac will get attacked/hacked? Wouldn't OS X Server include protective app's? And even if the hackers got through, the only damage they could do would be limited to the partition that OS X Server and the website is located on? I wouldn't want my whole network and my entire Mac Pro endangered. Please advise. Thanks!In no particular order...
All internet-connected systems can and do get probed, can and do get attacked, and the attacks may or may not be accessible. WordPress in particular has a long history of security vulnerabilities, so not only are you keeping OS X current and backed up and related tasks, you're also now responsible for keeping and updating WordPress and likely also MySQL database software (quickly!) after vulnerabilities are announced.
OS X Server is the whole operating system, not something that sits in a partition — you boot OS X (with Server.app installed) and your Mac now has various services that are available.
If your Mac does get breached, then your whole local network is potentially vulnerable. This is why some sites configure their web-facing servers in what's called a DMZ. The DMZ is a second part of the local network that is configured such that it cannot access most or (preferably) all of your core network. Low-end router-gateway-firewall devices do not offer DMZ capabilities. Some open-source router-gateway-firewall packages do (if you want to use your own spare x86 hardware), and mid-range and upper-end commercial router-gateway-firewall devices often also do offer a DMZ.
Backups of your server are part of maintaining security — if you get breached, then having a set of backups in depth — multiple backups, going back to (hopefully) before the breach are how you can recover your environment, should your server be breached. You'll want to keep copies of these backups out of the DMZ and/or off-site or otherwise out of reach of the potentially-breached server, as some attackers have intentionally deleted everything.
When you install OS X Server, you'll also need to get your local network going, your local DNS services going — you cannot solely reference off-network DNS servers successfully, properly-configured local DNS services are a prerequisite — and you'll need to get port forwarding for TCP port 80 and potentially TCP port 443 configured through your router-gateway-firewall device — and you'll need these ports to not be firewalled at your ISP, and you'll usually also want to have static IP address though a non-firewalled dynamic IP configuration can be gotten going. (If you think you may want to run SMTP mail services eventually, then you'll either need static IP, or you'll have to run via a relay service.)
Also check with your ISP, and see if your service tier permits servers. Some of them don't, on the non-static-IP service tiers.
In short: do you really want to be IT and network support? If you do, then all this stuff is entirely feasible and does work and does work well — usually — and you'll learn a whole lot about IT, IP, networking, DNS services, Apache web services, and system and network security. If you just want to blog, then using a cheap or free hosting service (somewhere off of your network) will be far less work. Can all this work? Sure! There are a number of folks around the forums that host their own stuff. Once you get the hang of it all, it's not that bad to maintain, either. -
Snow Server with Wi-Fi clients - good idea?
Hi everyone,
I am planning on purchasing a Mac Mini with Snow Leopard Server. Currently we have 2 iMacs, one MacBook Pro and a PC (will be going soon!) all networked with a wireless gateway and AirPort Express. Everything works well. However I want to consolidate things. Store all user accounts in one central location (so access, management, backup etc. becomes easier).
My question is if I buy the Mac Mine Server would I have to connect the clients (atleast the desktops) physically to the server through Ethernet or can ALL clients work over Wi-Fi? I think in offices/businesses etc. Ethernet is preferred and is common. What are the merits and demerits of Ethernet and Wi-Fi (other than the obvious ones)? What about speed? (we have 802.11g for Wi-Fi). Is accessing the Mac OS X Server over Wi-Fi in large numbers and no wired clients a common scenario?
Is it possible to turn the Mac Mini into a "headless" server. If yes, how?
If you have any links for this topic, that would be great!
Thanks,
KennethWired Gigabit Ethernet (GbE) networking is massively faster than 802.11n 5 GHz dual-slot is massively faster than 802.11b/g.
If you're sipping bandwidth, you probably won't notice the difference here.
If you're slinging any serious quantities of data around, you'll quickly find yourself moving to 802.11n 5 GHz dual-slot (locally 200+ Mb), or to GbE wired.
If you're in an environment with interference from other WiFi stations, then 5 GHz can avoid the racket in 2.4 GHz band. Regardless, wired networking typically has a much reduced likelihood of interference.
I generally prefer to run a mid- to upper-end firewall, and to use one or more AirPort or Time Capsule boxes as an access point (AP), and preferably with a gigabit wired "backhaul" to the network.
A Mac Mini is more than capable of running Open Directory and other such; just make sure you work out your archival strategy, lest you end up with a corruption or data loss or such. RAID is nice and a decent defense against a disk failure, but it doesn't protect against corruptions and deletions. (The Mac Mini Server can have interna; RAID. Other Mac Mini boxes can have external RAID added via the FireWire 400 or FW800 connection or (less desirably) via USB, and external RAID storage.)
The Mac Mini box doesn't need a head, but it doesn't hurt to have an old LCD and a keyboard available for hook-up to the box; that equipment is cheap and common and usually already available, and it can make various management tasks easier. If you want to administer the box fully remotely, then investing in a network power strip or remotely network-managed Less- Interruptible Power Supply can be useful; having a remote power switch can avoid a few trips over to the box to reset or reboot it.
And if you're setting up the network fresh, stay out of 192.168.0.0/16 private class c; use the 10.0.0.0/8 private class a or 172.16.0.0/12 private class b blocks, as either of these blocks tends to avoid VPN-related IP routing problems that tend to arise with subnets in 192.168.0.0/16. -
I use the same apple ID for all my devices, 2 iphones, 2 itouch, 1 macbook pro, 2 ipads. Becuse I have small children, can I change that and still, have control, and don´t need to buy the same things serveral times.
It is something I would avoid if possible. I would want to educate my children to think possessively and therefore of security. Yes, I know you are all family but at the end of the day you wouldn't want your children to be blaming each other for any problems that arise. Well, that's how I see it, for what it is worth.

Old battery for home use and 1 "traveller" battery? good idea?
My powerbook is my main computer and is connected to the adapter 90% of the time.
Would there be a noticable benefit from only using the new battery if i need to go on the road and leave the current battery in the laptop for home use?
If so is it best to leave the new battery half charged when not in use?You might want to read this page on the same site as the previous link, because most of my opinions are based on sources like that one, since I am not myself a battery expert.
So what would you class as a shallow discharge? 50 or
75%?
This is going to sound stupid, but I don't really put a number on it, only because I haven't seen one. I only see the advice about shallow vs. deep discharges. But I also don't think it needs to be that precise. The most damaging percentages seem to be 0% and 100%. I am not sure there is so much difference between 50% and 75%. Also, it's pointless to finesse it around that range because if you are on battery and you need to work longer, you should work longer. Being able to use the runtime you bought is more important than ekeing out incremental runtime preservation. I think this is why Apple's advice is so general, because it will essentially accomplish the goal. ("An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge.") Unplug it when you need battery, and plug it back in when you don't need battery.
As the battery will sometimes "rest" for a month or
more should i follow the apple battery care
suggestion and leave it at 50% ?
That seems fine. The page I linked to says 40%. Other sites say 40% and in the fridge. Again, anywhere in the ballpark is probably Close Enough.
Network, do you leave the battery at a specific
charge when resting?
Resting plugged in, 100% obviously, can't do much about that.
Resting and not in the laptop (short term offline), I aim for 90-95%. The only reason for that is on the site I linked to, it says "The worst condition is keeping a fully charged battery at elevated temperatures," so I figure it's easy to not have it fully charged. However, I will not drain it to 40% for short-term room temp storage, because that would require planning at least an hour ahead to charge it back up to 100% before going out the door. If you forget to do that, you walk out the door with your 40% charged battery, and that 5ucks.
Resting long-term, I'll drain to around 40%, put it in a ziploc bag, and put it in the fridge. Some say getting it down to fridge temperature isn't important, and I really don't know. But all agree, never put it in the freezer!!!!!
There is a balance here between convenience and runtime preservation. If you wanted to obsess over runtime preservation you could drain to 50% and fridge it every time you take it out of the laptop, but the reason that's totally stupid is that every time you want to use it you have to get it back up to room temperature and charge it. That's why I like to have different criteria for might-need-it-today storage (almost charged, room temp) and long-term storage (half discharged in the fridge).
The reason i'm hammering at this is that this
powerbook is nearing the end of its cycle and i doubt
i'll invest in another battery in the future.
Totally understand. That's why I looked into this stuff myself. But since I have a battery that's pretty new, and I think I can get decent runtime out of it for at least 2 years, that means it should last long until the ol' PowerBook G4 feels out of date enough for me to upgrade.
The main points here are, if you want to use your battery for its intended purpose, don't worry about micromanaging the percentages, just use it normally, don't drain it every time, keep it cool when possible. -

Partitioning the Harddrive for a scratch disk for CS1 & CS2
Hello all...
I need to see if there is a way to partition the harddrive on the work macs for the use of a scratch disk. We have a dual 2.0 G5 and a Quad.
The only thing is the fact that there are tons of materials on these macs as we are a advertising agency and are in the process of migrating all workable files to a new mac server that was ordered this week.
Can this be done without wiping the HD first?
Our apps mainly CS1 on some machines and CS2 on the Quad seem to run a tad bit slow. Could this be to not having a scratch disk for these adobe programs.
Or should we wait until the server has arrived and then just reformat the machines at that time?
Please help guys.
Dual 2GHz Power PC G5 & 4 x2.5 GHz PowerPC G5 Mac OS X (10.4.6)Never partition the boot drive. Even if it is used for scratch (and even if you set another drive for primary scratch the boot drive will still be used some). Keep your boot drive free of everything else except the system and applications.
Order some RAM, order a 2nd drive for each system. And a dedicated scratch disk - meaning you would need a 2 or 4-channel SATA host adapter for PCI-X.
You might want to use WD's 10K 150GB Raptor for boot drive (and yes, it works just fine on the DC/Quad G5s). The 10K 74GB Raptor makes a nice disk also and could also be used for scratch disks in a RAID. Use your original OEM drive just for local data.

2) How to SMI Label/Format a disk while OS Installation in Solaris 11.1?
As we know that ZFS is the default filesystem in Solaris 11.
We have seen in the Oracle documentation that for rpool below are recommended:
- A disk that is intended for a ZFS root pool must be created with an SMI label, not an EFI label.
- Create root pools with slices by using the s* identifier.
- ZFS applies an EFI label when you create a storage pool with whole disks.
- In general, you should create a disk slice with the bulk of disk space in slice 0.
I have seen the solution that using format -e, we change the labelling but all the data will be lost, whats the way to apply a SMI Label/Format on a rpool disks while OS Installation itself.
Please provide me the steps to SMI Label a disk while installaing Solaris 11.1 OS.Oracle recommends below things on rpool: (thats reason wanted to apply SMI Label)

FileVault 2 encryption for the startup disk not a good idea for server?
Hello,
in the Mac OS X Lion help files it states the following:
With Mac OS X Lion Server, encryption isn’t recommended for the startup disk or any disk that stores service data. If these disks are encrypted, the server can’t restart until you go to the server and enter the password at the server’s keyboard. If you use Lion Server to share an encrypted disk, the disk isn’t available to users until you enter the password at the server’s keyboard.
Does this also apply to regular Mac OS X Lion? I would like to be able to wake up my iMac from sleep through SSH, and occasionally be able to restart the system remotely if I need to. If the above is true it seems like it would disable me from doing this.
ThanksDoes anyone have an answer?

Help: Partitioning a Scratch Disk for CS3
Hello Gang,
I finally got around to installing 2x500GB Western Digital RE SATA RAID Edition hard drives in my new Mac Pro. They are in a RAID 0 striped configuration and will be used as my scratch disk. If I understand things correctly, I need to partition a certain portion of this RAID Scratch disk for CS3. I have no prior experience doing this. Anyone care to walk a newbie through the process? Thank you!
MikeIt is best to have the scratch disk a different disk than the OS and program disk. The size needed depends on how big of images you will be using, how many you will have open at one time, how many layers or smart objects you could add, and a few other things. Some do OK with 20 gigs, others have 300+ gigs.

Having trouble partitioning my disk for bootcamp with windows 8.1
I have a 2012 MacBook Pro Running i5 Processor, 8Gb RAM with 500GB HD running OSX Yosemite 10.10.2. I was able to successfully install Windows 8.1 using boot-camp assistant and partitioned it with the minimum of 20Gb. I tried installing Microsoft Office Pro 2013 on the Windows 8 OS after the boot-camp process yet with the installation process it used up 19 out of 20Gb not allowing me to install anything more then 1Gb. The file for Microsoft office was 4Gb. I went back to OSX to extend the partition space for Windows 8 OS and wasn't able to adjust it manually. Question is if i have to do the install process again from the beginning and add more space to the partition or if there is another solution without deleting the OS.
From Boot Camp 5.1: Frequently asked questions - Apple Support
Can I resize the Windows partition after installing Windows?
No. Back up your important files, then use Boot Camp Assistant to delete the old partition and create a new one. -
I'm getting the following error when trying to enable disk de-duplication on a volume on my Windows 2012 R2 file server. The error is:
"There was an error updating Data Deduplication on volume: MSFT_DedupVolume.Volume='\\?\Volume{8dfc4322-9997-11e3-93f5-005056a84b9b}\' - HRESULT 0x8056530b, The specified volume type is not supported. Deduplication is supported on fixed, write-enabled
NTFS data volumes and CSV backed by NTFS data volumes."
The volume in question is a 1TB VMFS volume mounted to the virtual machine that is the Windows file server. I could find no info anywhere that references this error as it relates to a standard mounted volume or VMware or VMFS.
Any ideas on what could be the problem or how to fix it? I could find nothing in the log files other than an entry which is basically a repeat of the error above.
Any help would be greatly appreciated.
- ADEHART
P.S. This is a volume that was previously mounted on an older Windows 2003 server. Not sure if that may make a difference.have you compared this issue to the ones that are successful and compared what is different?
Have you made sure of the following:
Servers
See the following list for server requirements for deduplication:
• Server hardware should meet the minimum requirements for running Windows Server 2012. The deduplication feature was designed to support minimal configurations such as a single processor system with 4 GB of RAM and one SATA hard disk drive.
• If you plan to support deduplication on multiple volumes on the same server, you need to plan an appropriately size for the system to ensure that it can process the data. The general rule is that the server needs 1 CPU-core and 350 MB of free memory to run a deduplication job on a single volume, and that job can process about 100 GB per hour or around 2 TB per day. Deduplication scales with additional CPU core processors and available memory to enable parallel processing of multiple volumes.
For example: If you have a server with 16 CPU core processors and 16 GB of memory, deduplication uses 25% of the system memory in the default Background Processing mode, and in this case, that would be 4 GB. If you divide by 350 MB, you can calculate that the server could process about 11 volumes at a time. If you add 8 GB of memory, the system could process 17 volumes at a time. If you set an optimization job to run in Throughput mode, the system will use up to 50% of the system’s memory for the optimization job.
• Data Deduplication supports up to 90 volumes at a time; however, deduplication can simultaneously process one volume per physical CPU core processor plus one. Hyper-threading does not impact this because only physical core processors can be used to process a volume. A system with 16 CPU core processors and 90 volumes will process 17 volumes at a time until all 90 volumes are done, if there is sufficient memory.
• Virtual server instances should follow the same guidance as physical hardware regarding server resources.
Volumes
Volumes that are candidates for deduplication must conform to the following requirements:
• Must not be a system or boot volume. Deduplication is not supported on operating system volumes.
• Can be partitioned as a master boot record (MBR) or a GUID Partition Table (GPT), and must be formatted using the NTFS file system.
• Can reside on shared storage, such as storage that uses a Fibre Channel or an SAS array, or when an iSCSI SAN and Windows Failover Clustering is fully supported.
• Do not rely on Cluster Shared Volumes (CSVs). You can access data if a deduplication-enabled volume is converted to a CSV, but you cannot continue to process files for deduplication.
• Do not rely on the Microsoft Resilient File System (ReFS).
• Can’t be larger than 64 TB in size.
• Must be exposed to the operating system as non-removable drives. Remotely-mapped drives are not supported.
Note
Files with extended attributes, encrypted files, files smaller than 32 KB, and reparse point files are not processed by deduplication.
