Questions before whole disk encription (dmcrypt+LUKS)

I am intending to encrypt my two internal laptop drives. That means a 128GB SSD (partitions: Arch, swap, Windows7) and 750GB HDD with most of the data (two partitions: data, and system backup).
I intend to do it using dm-crypt + LUKS (my understanding is that's the best method for the job), and I am going to do it in-place, which means on existing system/data, using this ingenious script: http://www.johannes-bauer.com/linux/luksipc/
However, I have some questions that I was unable to find answers to:
1. I am going to encrypt entire SSD. I know that SSDs work better if they have manual overprovisioning left so that TRIM may work properly, extending the life and performance of the SSD.
For this reason, right know on my 128GB SSD (Samsung 830) I have 12GB of unpartitioned space left.
But if I encrypt the entire drive, then even if the unpartitioned space is still there when I run gparted from within the encrypted system, will the TRIM mechanism still see it as unpartitioned, or will see the whole disk as partitioned and occupied due to full disk encryption?
2. If I get it right, I need to separate boot partition, and leave it unencrypted. So I will put it somewhere on that SSD. But if I intend to do dm-crypt+LUKS block device encryption, doesn't it mean that it will encrypt everything on that SSD? If so, then should I go around it?
3. I am not clear on the process itself, and wiki does not say anything about it. I think I need some kind of key file to access encypted partitions. But when in the process and how am I supposed to generate it? And what to do with it so that system remains bootable from syslinux? wiki.archlinux.org/index.php/Disk_Encryption is very rich in theoretical information, but I found nothing about the encrypting process itself.
4. As I mentioned, the SSD contains also a small Windows partition for duel boot. Do I need to take some extra steps to ensure it runs, or will it work as long as the Arch boot work?
Does anyone know answers to (any of) those questions?

@Lockheed SSD do not interpret the disk table as far as I know, therefore it does not make a distinction between "unpartitioned space" and "partitioned, but unwritten space". The involved layers for a LUKS-encrypted partition is:
+------------+-------------------+------------------------------------+
| ext4 | /dev/mapper/Arch | mount with "discard" (default) |
+------------+-------------------+------------------------------------+
| LUKS | /dev/sda1 | cryptsetup --allow-discard option |
+------------+-------------------+------------------------------------+
| phsyical | | disk needs TRIM support |
+------------+-------------------+------------------------------------+
When a filesystem is mounted, you can use fstrim / to TRIM free space. To TRIM a whole drive (e.g. just before reinstalling when you have a backup on a secondary disk), you can use blkdiscard /dev/sda.
(2) "block device" likely refers to the model where data is read/written in blocks rather than per byte ("character device" such as /dev/null). Encryption is also done per block, not per byte. If you write a file of 1 byte, then the encryption would still touch the whole block size which is more than 1 byte (typically a power of 2, e.g. 512 kiB).
(3) with LUKS you can have multiple key slots. Knowing one of them does not give any knowledge over the other key slots. Keep all keys secret, only one is needed to access your data... By the way, while I used a key file to migrate my old data to the new encrypted partition, I already had a passphrase in a key slot. The keyfile was just occupying another key slot. At boot, the keyfile would be used to unlock the device, but in case of emergency I could use the passphrase instead.
(4) if you are not going to need it, then just wipe it completely (possibly after making a backup, just in case.). If you ever need Windows, use it in a virtual machine. As ball said, LUKS is incompatible with MSWIN.

Question about using ZFS root pool for whole disk?

I played around with the newest version of Solaris 10/08 over my vacation by loading it onto a V210 with dual 72GB drives. I used the ZFS root partition configuration and all seem to go well.
After I was done, I wondered if using the whole disk for the zpool was a good idea or not. I did some looking around but I didn't see anything that suggested that was good or bad.
I already know about some the flash archive issues and will be playing with those shortly, but I am curious how others are setting up their root ZFS pools.
Would it be smarter to setup say a 9gb partition on both drives so that the root ZFS is created on that to make the zpool and then mirror it to the other drive and then create another ZFS pool from the remaining disk?

Just a word of caution when using ZFS as your boot disk. There are tons of bugs in ZFS boot that can make the system un-bootable and un-recoverable.Can you expand upon that statement with supporting evidence (BugIDs and such)?

I asked this question before but I can't find it now. Anyway, I'm trying to import a DVD video that was made on a MAC and use it on a new iMovie project.
How do I do the importing.

If the video is already on a DVD:
You need to convert the VOB files in the TS-Folder of the DVD back to DV which iMovie is designed to handle. For that you need mpegStreamclip:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
which is free, but you must also have the Apple mpeg2 plugin :
http://store.apple.com/us/product/D2187Z/A/quicktime-mpeg-2-playback-component-f or-mac-os-x
(unless you are running Lion in which case see below))
which is a mere $20.
Another possibility is to use DVDxDV:
http://www.dvdxdv.com/NewFolderLookSite/Products/DVDxDV.overview.htm
which costs $25.
For the benefit of others who may read this thread:
Obviously the foregoing only applies to DVDs you have made yourself, or other home-made DVDs that have been given to you. It will NOT work on copy-protected commercial DVDs, which in any case would be illegal.

If you are running Lion:
From the MPEG Streamclip homepage
The installer of the MPEG-2 Playback Component may refuse to install the component in Lion. Apple states the component is unnecessary in Lion, however MPEG Streamclip still needs it. See this:
http://support.apple.com/kb/HT3381
To install the component in Lion, please download MPEG Streamclip 1.9.3b7 beta above; inside the disk image you will find the Utility MPEG2 Component Lion: use it to install the MPEG-2 Playback Component in Lion. The original installer's disk image (QuickTimeMPEG2.dmg) is required.
The current versions of MPEG Streamclip cannot take advantage of the built-in MPEG-2 functionality of Lion. For MPEG-2 files you still need to install the QuickTime MPEG-2 Playback Component, which is not preinstalled in Lion. You don't have to install QuickTime 7.

Disk utility gives "Error: Partition map repair failed while adjusting structures to fit current whole disk size"

I am getting the following error when running Disk Utility (under ML) on an exteral USB hard drive:
Error: Partition map repair failed while adjusting structures to fit current whole disk size.
I get thsi when I ask Disk Utility to "Repair Disk" at the top level of the disk hierarchy (i.e. not on one of the partitions within the disk but on the disk itself). I was not getting this error with Lion on the same disk before I upgraded from Lion to ML.
It seems like a bug in ML. I found websites where they suggest that you just run Lion's Disk Utility and it will show the disk to be fine.
Any thoughts?

So, I finally seemed to have resolved things with the Seagate 4TB Firewire external drive. If you Google about, you will find a thread on Seagate's own support forum that describes how to disable the sleep function on the drive. You CANNOT ALLOW THE DRIVE TO SLEEP WHILE CONNECTED TO YOUR MAC.
After a lot of reading, here's what I think is happening: the drive goes to sleep, after some period of inactivity, and when you shutdown your Mac, OS X tries to write something to the drive as part of the dismount / disconnect / shutdown process. That fails in some manner, leaving the drive 'corrupted' at the filesystem or partition level.
Then, on the next boot-up, Mountain Lion tells you that it cannot repair the drive and it mounts as read only. Your only fix at that point is to re-partition / re-format and start over (which is big fun with 3TB of data to copy back on to the drive).
If you prevent the drive from sleeping, whenever it's connected to the MacBook, then the above process doesn't occur and voila, the drive just works. So far, I haven't had any problems with about a week of starting / shutting down my MacBook connected to the offending drive (translation: I was going to return the drive, but the problem is clearly with Mac OS X Mountain Lion).

Thinking of upgrading to SL,But i have some Question before moving to SL

I will be glad if anybody can help me with my questions before moving to Sl.first,i like to know,after upgrading or fresh install,do i need to reinstall another windows xp on the machine,cos i use VMware Fusion?
Secondly,What option is the best,Upgrade or Fresh install?
Can i make backup using an external usb2 drive? and what can i do so my old setting remain after installing SL.Setting like my Chat history,and will my applications use the same lience key?
Anybody with usefull advice?
What important it the history of chat i had on my pc.i work for a company as a mid man and this history help me to remember last diccussion with client..

In your place, I would move to SL if, and only if, I had an external drive with a bootable clone of my internal on it. I think that there is enough risk in going to SL that such conservatism is warranted. I would not use time machine alone for backup/restoring when moving to an OS upgrade or doing a point update. This app can be problematic and, consequently, its solo use is too risky for me in these cases. You will be able to extract your settings, files, and programs from your clone if you do an erase and install. You can erase and install or upgrade with any SL disk except the gray ones that come with specific machines. I still prefer to erase and install.
To erase and install (see upgrade option below), start up to your DVD and stop after selecting your language. Use the menus to start Disk Utility and erase your drive. Quit Disk Utility and proceed with your installation. At the end, you will be able to choose to reclaim your settings, files, and apps from the clone (plug in the external at the point of the last install restart).
If you do not like SL, then you can restore your internal using the clone. I would do all cloning and related restoration with SuperDuper, Carbon Copy Cloner, or some other up-to-date cloning app, including Disk Utility. Your clone also will serve as an independent backup for your data.
Upgrading is a very sound process on a Mac. Still, I also would insist on having a bootable clone on an external before upgrading. An upgrade is performed by installing over your existing installation from the desktop or having started from your SL DVD. All your programs, data, and settings will be present after an upgrade, but incompatible programs will be archived.

PGP whole disk encryption and Snow Leopard

I've got Leopard with PGP whole disk encryption on it but am having difficulties in installing SL as it want to wipe the HD.

Hi Thomas
Sorry I was trying to save this as a post rather than a question but it hasn't seemed to save my edited message for some reason.
PGP for me is better in that it encrypts the whole disk rather than just the user account. Using FileValut is really unfriendly with TimeMachine, it slows the computer down and for a lot of people you can't actually activate it if you don't have enough space remaining on your HD.
PGP will encrypt your whole disk without slowing it down or taking up any additional space. It also works better than a firmware password that can be bypassed by resetting the PRAM.
The problem with PGP is that in trying to install Snow Leopard the installer doesn't recognise the boot partition even once the encryption has been removed. This causes it to prompt the user to wipe the HD. Here's the solution I found after some pain I might add:
Remove all the encryption from your HD and Time Machine.
Back up!
Start the Terminal from the Leopard Installer (Utilities->Terminal). This has to be done from the installation disk.
Type diskutil list
Identify your system disk. In most cases it is disk0s2
There's a volume called "Boot OSX" on the next partition, probably disk0s3. If your system is different than disk0, then use that identifier in place of disk0 for the rest of these instructions.
Type diskutil unmountdisk disk0
Type gpt remove -i n disk0 where the n is the last number of the boot partition; for example, disk0s3 would be 3; you would type gpt remove -i 3 disk0
Exit Terminal
P.S. if you accidentally remove the wrong partition OSX wont start up but don't worry, run disk utility from the installation disk and create a new partition and restart. All your data will still be there!

Questions on asm disk discovery:

Questions on asm disk discovery:
1）What is the relationship btween asm_diskstring in the init.ora and DiscoveryString in the GPNP profile.xml?
2) Which one of the above two finally accounts for the disk discovery process?
3) We know that asmlib disks are self describing at the disk header. This overcomes the disk name/path persistency issue as we no long need to rely on the path to discover the asm disks, by setting asm_diskstring='ORCL:*' , ASM instance will identify the right disks automatically. However, I am not sure if setting asm_diskstring='ORCL:*' is the most economic way to do the discovery as I am not sure if Oracle will have to probe all the disks on the OS to determine the right disks. If Oracle has to screen all the disks in this way, then I think setting asm_diskstring='<path_to_asmlib_disk>' will be much faster, although this will be open to the persistent problem. Is my understanding correct?
Thanks.

From my understanding all disk you see in /dev/oracleasm/disks are the disks in your system that been discovered by asmlib at discovery stage.
Currently, due to bug 13465545, ASM instance will discover disks from both locations, ASM_DISKSTRING and gpnp profile, which can cause some mess in disk representation for asm. You can check the settings using asmcmd command: dsget, and set to be the same using dsset.
I think its more secure to set ASM_DISKSTRING to only the disks used by asm instance.
ASMCMD> dsget

Ed

E71: annoying confirm connection question before s...

hello
how can I disable the confirm question before a synchronization?
I'm synchronizing over a bluetooth connection. The user guide tells me to click on authorize but I can't find the opportunity to choose this option. Is this done on the E71 or in the Nokia PC Suite application?
thanks for any hints

hello,
do you have any idea how to sync my e71 offline with outlook emails/inbox. there's no checkbox for emails on the synchronisation set-up screen (only contacts, tasks, calendar). I've been doing this for years with my Palm Treo. I can't believe it's not a function on this high-end Nokia?

What logical device for COMSTAR whole disk iSCSI?

Hi,
We have a poor man’s cluster with data redundancy through locally mirrored iSCSI disks.
Solaris 11.1 x86 + Solaris Cluster 4.1
Most all of the instructions I found describe mirroring the physical disks on the SAN, making a ZFS volume and iSCSIing this volume.
We’d like to use the whole disk in raw mode without any filesystem between the physical SAS disks and the iSCSI target.
What is the correct logical device for stmfadm create-lu ?
One of our disks pairs was configured with LU data file /dev/rdsk/c0tXXXd0
After a few months of use, the zpool has become degraded and scrub fails to fix the problem. zpool status claims both disks are degraded, but smartctl test gives both physical disks a clean bill of health.
We used this zpool/zones for testing automatic failover during node failure, so it is very possible that this pool had been corrupted in the course of these tests and the logical device selection has nothing to do with the problem.
We have another pair of disks configured with /dev/rdsk/c0tXXXd0s0
I benchmarked the two configurations by copying data to a dataset on the mirrored iSCSI disks.
/dev/rdsk/c0tXXXd0s0 gave a result of 80 MB/sec while the /dev/rdsk/c0tXXXd0 configuration gave a result of 50 MB/sec.
This may be due to the fact that the /dev/rdsk/c0tXXXd0 configuration is degraded.
I've seen some references to using c0tXXXd0p0 but I haven’t had a chance to try this out yet.
Thanks for your help and advice.

I tested the volume based iSCSI method and performance wise it sucks donkey d1ck.
If it had been 50%, slower we could always buy another node, but the performance was truly pathetic.
My make shift benchmark comprises of cp:ing 10 gigs of random test data from the local disk to the HA mirror of iSCSI disks and a sync at the end.
Volume based iSCSI results          17m25.932s total write time, 9.8 MB/sec
XXd0s0 whole disk iscsi                2m13.468s total write time, 77 MB/sec
I made the test configuration as zpool->volume->iSCSI->efi-part according to the following instructions:
www tokiwinter com / solaris-cluster-4-1-part-two-iSCSI-quorum-server-and-cluster-software-installation /
I made the volume 5% smaller than the available space to account for metadata, spare blocks, ect.
I did a little digging into my current partition tables and there is corruption/weirdness in in both the XXXd0 and XXd0s0 cases.
The XXXd0s0 configuration has not seen a lot of reads or writes, that why it still appears to be ok.
I’m convinced that in 6 month, it will be in just as bad condition as the XXXd0 configuration.
prtvtoc:ing one of the XXXd0 disks shows:
*                          First     Sector    Last
* Partition Tag Flags    Sector     Count    Sector Mount Directory
       0     24    00        256    524288    524543

I was impressed by partition 24 being 4194304000.00 TB or 4 zettabyte disk size. That’s a great compression ratio for a 146G drive
Has anyone in the community successfully used iSCSI without zpools and volumes on the physical disk?
If you have, please share your results and configuration. I’ve hit the wall with this one.

A few questions before buying a spectre x360

Hi I'm considering buying a 13" Spextre x360 once Win10 arrives in final version - but have a few questions before going ahead. Mostly looking into the 4041no (i'm from Denmark) - or similar configuration. I need a configuration with at least 500 GB of hard drive and 8 GBs of RAM. 1. Will the spectre support all the new windows 10 touchpad gestures (similar to OS X/Mac gestures)? I have read something about the touch pad on the not being a "precision touchpad" but instead being run by synoptic drivers or something. Don't know exactly what it means. I come from a Mocbook Pro - and these gestures are so good. 2. One of the things some talk about in reviews is heat - that the x360 gets very hot to hold. Even just browsing the web. And also fan noise being loud. Any experience here - is it just a few unfortunate buyers, or are any of these issues generic. 3. Browsing the web there are so many different model numbers, that i can't keep up - and some of them seem to be identical configurations. Is there any overview of what is what. For instance 4041no and 4040no seem identical - but there is a difference in price, at the stores i have seen online. Similarly there is a 4030no and a 4032no. What are all these models. different numbers for every store/country/????. Any help here.. 4. The 4041no model i'm looking into has this QHD screen. Very high resolution. How is that in everyday life for surfing the web (mostly Chrome), Photoshop, watching movies local/streaming and more. It seems that everything will be very small, or is there scaling options or other stuff that makes this high resolution usable in real life. Or maybe lower the resoltion in settings. Any experience? I will soon try to find one in a real store to try out if possible. Think i'll start with those questions :-) And maybe also some generel feedback on the spectre x360. Thanks /Jonas

Hi Jonas,
I have the 4014 model (core i7, 256gb ssd, 8gb ram and FHD screen) so I can answer some but not all of your questions.
1. Touchpad is responsive and easy to use for me. Just upgraded to windows 10 and multi touch gestures are working fine. Three finger tap to open search, four finger tap to open the quick settings panel. Three finger flicks do app switching and minimising. The pad is controlled by the synaptic driver, but it has quite a few options and seems to work well for me.
2. Heat is not an issue for me. Sure, it gets warm when running intensive tasks, but as long as you are not pushing the cpu for long periods of time, it will be fine on your lap. Browsing the web, the fan will come on briefly when I load 10 or more tabs at a time, otherwise the fan will remain off.
Being an aluminium chassis, it has the ability to transfer heat out of the shell more easily than a plastic laptop, so you might notice it getting warm quicker, but it also cools down fast.
The fan is no louder than any other laptop I have used.
3. Can't help you with model numbers, sorry.
4. I'm finding that a lot of applications do not scale correctly on my FHD screen, so I can imagine that the QHD would be the same or worse. Most of the time, you can get the applications to look better by turning off display scaling in the compatibility settings. Sometimes this means that the application then looks smaller on screen, though text, images and icons are sharp, they are harder to read. The QHD would make these apps even smaller. I do not think QHD is worth it on a small screen for this reason.
In general the laptop works well. I use it in my job as a teacher, and being able to convert from laptop to tablet is a huge benefit. It is super fast to start up and easily gets me through a school day (quite often getting home with more than half a charge). I will just close the lid between uses and it sleeps, drawing very little power. It is capable of running Photoshop and office apps, while browsing the web and doing some light duty CAD modeling on the side.
One small issue that I and a few others have had is a crackling, buzzing noise due to the processor power regulation. Only audible in really quiet rooms or when putting an ear close to the device, when the computer is idling. Not an issue for everyday use, but something to be aware of if you have sensitive hearing or are annoyed by slight imperfections.
Hope that answers a few of your questions.

when you install solaris.
Your problem is that you have assigned 73 GB for your / (root)
and 63 GB for your swap. That's not the problem that I see. The problem is that the Solaris partition (and therefore the Solaris VTOC label inside) is only for 136GB. But the actual underlying storage is 409GB. So the entire partition and the VTOC have to be rewritten.
You only have 2 options. Either re-install Solaris, of re-partition the disk.
If you don't have a spare disk to copy root to and you want to use
the whole disk, with just one / root partition, you will need to shrink /swap
create another slice to copy root to temporarily, and then re-partition your disk. Agreed reinstalling is easiest. But moving slices around will not let you change the VTOC size.
eg:
boot from CD into single user mode.
partition the disk so that eg:
swap is 3 GB. eg: ( from cylinder 1 to cylinder 400 )
partition 3 is 7 GB ( from cylinder 401 to cylinder 1318 )
( if 7 GB is enough to hold all your / data )
write the disk label out
newfs partition 3
mount / on /a
mount partition 3 on /mnt
Copy everything from /a to /mnt eg:
rsync -vaxH /a /mnt
or
find /a -xdev -print | cpio -pdam /mnt
umount /a and /mnt
re partition the disk so that / takes all the free space.If that were your goal, you wouldn't have to move anything. Just repartition and use 'growfs' on the root filesystem directly (while booted from CD).
eg ( starting at cylinder 1319 to cylinder 17816 )
write disk label out
newfs part 0 for /
mount / on /a and part 3 on /mnt
copy everything back from /mnt to /a
Check /a to make sure everything is there.
umount /a and /mnt
re partition the disk to make /swap 10 GB
( starting at cylinder 1 to cylinder 1318 )
write disk label out.
And that's it.
The disk you are working on is 17816 cylinders in size.
yet down the bottom you say that :
Total disk size is 53502 cylinders
That tells me there are 4 disks in the raid 5 set, and that
you have probably been presented with 3 x 136 GB disks.
That means that you should have 2 x 136 GB disks free.
Use one of these to copy your /root to. and then
re-partition your first disk and copy data back.
Or partition another disk correctly, write a boot block to it
Copy your root data to it, and boot from it.The entire disk is presented to the machine (as seen in the fdisk output), but the Solaris partition is only using the smaller portion of it. You can't create a second Solaris partition and use it at the same time, either. Only one Solaris partition can be used at a time.

Questions before I SWITCH to Mac...

Few questions before I switch to Mac (hoepfully when Leopard comes out)....
Currently I have a Dell XPS Media Center PC and a Vista laptop.
1. TV/DVR CAPABILITIES: I love using my PC as a tv tuner & DVR. Does mac have this capability? If I run Vista on the Mac will my Media Center, TV tuner, etc... run the same?
2. PDA SYNC: Will the Mac sync calendar & contat items with my Windows based PDA?
3. WEB DEVELOPMENT: I am a ASP.NET developer. Can I do this on a mac easily? If I have to use Windows on the mac to do this, can anyone speak on the performace?
4. SHARING FILES BETWEEN OS & COMPUTERS: Can I share files with other XP or Vista pcs I have in the house? Can I share files between the Mac and Vista OS on the SAME machine?
5. DUAL MONITORS: Does the MacBook Pro or iMac support DUAL monitors?
6. CS3 QUESTIONS: I'm thinking about purchasing Photoshop CS3, Flash CS3, etc... Can I install them onto the Mac side and the Vista side of the same machine?
Thanks! I was a PC lover, but now I'm turning into a MAC LOVER!!!!
Thanks everyone!!!

1. No way to tell. You'd have to install the card and the drivers too see if they work.
2. http://www.markspace.com/missingsync_windowsmobile.php
3. You'd have to install Windows if you want to develop for .Net
4. Yes and yes
5. Yes
6. You'd need to buy both Mac an PC versions of CS3

PGP Whole disk Encryption but for Windows Partition only ?

Hi,
Slightly unusual situation here. I want to use my MacBook Pro at work and home. OSX at home and XP at work. Now at work they have a strict policy of only allowing computers on the network with PGP Whole disk Encryption. I've looked into this and there doesn't appear to be a way of setting this up via bootcamp because PGP makes use of MBR which as far as I know bootcamp doesn't use and PGP themselves say bootcamp isn't supported.
Looking around the web there are various articles about tripple/quad booting Mac systems not using bootcamp but things such as Grub or reFIT. I'm wondering if there is a way of using this boot technique but using the partition option when installing PGP for windows and only setting it up on the defined windows partition.
Has anybody tried this or have alternatives ?
Thanks in advance
Steve

Hi Steve:
Windows has a boot manager built in. Windows can be installed on a logical NTFS partition, the boot
manager can sit on a tiny fat or fat32 primary partition. I have used this arrangement on my PC's
many times. I have not tried it on a Mac, but it should work. You will need to have some working
knowledge of partitioning to pull it off.
I don't know how PGP designed their software, but it should support this arrangement, unless they
have some cheesy engineering design built into their software that would prevent it from working.
The windows boot manager has been with NT from the beginning. It is not rocket science, NTLDR
sits in the usual spot reserved for system boot files, the boot ini file tells NTLDR what partition
the /windows/system32/ntoskrnl.exe is on and NTLDR passes the ball to ntoskrnl and away
she goes if everything is Kosher. Windows boot manager can boot other OS's as well.
Be aware though that windows may assign a drive letter to the windows installation other than
"c" (usually "d" of "f". That doesn't keep anything from working though.
