Help! Xsan 1.2 trashed my san!! Can I go back to 1.1? Kernel panics!!

As soon as I upgraded the server/controller and clients to Xsan 1.2, the clients would no longer mount normally (Xsan Admin either didn't show the client at all or showed client with an orange dot and would not mount). The only way I could get the client's to mount was to de-install Xsan on the clients (with the new uninstaller) and then reinstall Xsan 1.0, 1.1 update, and 1.2 update. After re-entering the client serial numbers, all appears well from the server side: the Xsan volume can be started and stopped and mounted/unmounted on each client.
But... everytime I try to open the Xsan volume in the Finder of a client machine, I get a kernel panic error. And.. when I mount the Xsan volume on the server and a double-click to open the volume in the Finder there, I also got a kernel panic error. Ouch!!
So now the question is, how can I go back to Xsan 1.1? I know how to do this on the client machines (deinstall 1.2, reinstall 1.0 and 1.1 update). But will this same tactic work on the server/controller without trashing my san?
Is there anyway to mount the san volume via AFS and copy the data to a backup volume?
BTW.. I did run the cvfsck utility as root on the server and it did report that it fixed hundreds of errors (can't remember the type; seems like it was 'i--' something). Since fixing the errors on the first run, cvfsck no longer reports errors on subsequent runs.
My setup: Xserve G5 10.3.9; G5 dual 2.5GHz clients with 10.3.9; Sanbox 5200.
Any help is much appreciated.

John...
I'm the one who posted the info...
Note, not responible for this stuff, just letting you know how I recovered.
Here is what I had to do to clone my 1.2 MDC and make a new 1.1 MDC.
1. Logged into the MDC server as root.
Copied the Library/filesystem/xsan/config folder
2. Shut down the MDC
3. Set up a clean machine hooked up to the san.
In our case a powerbook with 10.3.9 was hooked up to one of my G5 edit suites, booted the PB in target mode and mount it's OS to power the G5.
4. Installed XSAN 1.1, authenticate as MDC - low.
5. Logged into the PB/G5 as root and copied the MDC config files over, but left the secert file on the fresh system alone. (Make sure the ip address of the fresh system is the same as the org MDC)
6. Rebooted and assumed control of the XSAN.
7. Uninstall 1.2 on my edit suite and install 1.1, make it controller med
8. Assume control and shut down the Powerbook system.
9. Repeat uninstall and reinstall steps on remaining systems and set controllers as required.
I hope this helps and good luck.

1 HFS volume needs repair -- can't boot from OS X Tiger "kernel panic"

I just searched the support discussions and did find an answer so hopefully someone can help me. Today I ran Disk Utility on both my G4 powerbook and G5 desktop. Both have Tiger 10.4.8 on them and have been running good. To my surprise both came back with a message saying:
1 HFS volume checked
Volume needs repair.
So I booted off my Tiger start up disk on the laptop first and went to utility and repair disk and all was good. The message came back that the volume was repaired.
When I tried to do the same thing on my G5 desktop my computer went to a gray screen and gave an error of “kernel panic” with a page long message. I shut the computer down and rebooted normally and all was fine. I then went back to disk utility and clicked on Verify Disk again to see what it said and here is what I got:
Verifying volume “MacOS250”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Illegal name_
Illegal name_
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
The volume MacOS250 needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
So i noticed that under:
Checking Catalog file.
Illegal name_
Illegal name_
came back twice. I have no idea what this means. At this point I tried to boot from DiskWarrior and the computer just sat in a state of limbo for an hour or so. I know DW can take some time but 1 hour was pushing my patients so I shut it down and rebooted normally and all was fine again except I still get the message above. I then methodically backed up all my docs, movies, photos etc to my second hard drive. I tried to boot again from Tiger and got the same “kernel panic” message. Can anyone help me?
Thanks,

Maverick922 Before you erase, you might want to try and run fsck first even though it says you are using HFS+
http://docs.info.apple.com/article.html?artnum=106214
Another reason is your version of disk utility on the Tiger disk might may not match the newer version of 10.4.8 My Tiger start-up disk utility is 10.5 while the OS X version on my HD is 10.5.6.
The Finder along with other applications do not like you naming a file with a period in front of it. This turns it into a Unix dotfile and it then becomes hidden.Hence, illegal name.This may have been done by accident or with purpose.
And a little more to read up on, http://docs.info.apple.com/article.html?artnum=302672
If these don't help, sherry johnson's suggestion is probably the next step.

Can too much memory lead to a kernel panic on a MacBook Pro? specs 2.4GHz intel core i7 16GB DDR3 RAM late2011..My laptop began suffering from kernel panics 3 mos ago first noticed using public wifi. Gone thru apple support all the way to engineers

Can too much RAM memory in a late 2011 model macbook pro lead to kernel panic? That is what I was told by a senior supervisor from apple support who troubleshot this issue.First noticed this problem in Dec 2014 while using a private wifi at a relative's home. Did not occur again until Feb1 using a public wifi at a hotel. Never happened on my private wifi network until last night attempting to use airplay. ( have used airplay before without issue). Late 2011 MacBook Pro running 10.9.5; 2.4 GHz Intel core i7, 16 GB DDR3,AMD Radeon HD 6770m 1024 MB graphic card. The laptop came with 8GB RAM and I installed 8 GB about 2 years ago for some reason I cannot remember... probably because I thought the system was slowing down a little. I know that sounds silly. I do not run multiple programs at a time except I leave 6-8 website tabs open simultaneously. I don't photo or video edit. I would describe my use as "light" based on reading these blogs.I had purchased apple support and spent hours on the phone with them in early Feb moving up through support and senior support to sending logs to the "engineers." Of course lots of things were done some of which I am sorry to report I cannot recall their technical definitions. Deleted 3rd party apps/programs; re-worked start up menu; re-installed operating system; reset " this, that and the other" using acrobatic simultaneous key strokes both in and out of safe mode..Anyway the results from the engineers came back and they suggested that if it happened again I was to remove the 8GB of RAM I had installed as the system was getting confused as to which chip to use.( that is my interpretation of what was said..prob dumbed down for me)...Anyway 1 day after these pronouncements came down I read that Apple had agreed to fix graphics cards in some late model 2011 MBPs. I felt this was unlikely to be the issue given all that had been done including an extended hardware test but called the Senior Support Supervisor I was working with to ask him to make sure. He never phoned me back. Should I go to the trouble of removing 8GB of RAM from my laptop? Of course I will try it as the alternative is a new computer.Blogs read that this model can support 16GB but Apple didn't test for it. Senior Supervisor claims this is my trouble. Does that make sense? Not to me....but it is clear to all my level of knowledge. Can a malfunctioning graphics card be missed by an extended hardware test? I appreciate comments.

The RAM needs specs as shown below.
Maximum Memory
16 GB (Actual) 8 GB (Apple)
Memory Slots
2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM

Can't update to 10.6.8 kernel panic and pcscd.pub wrong block count

Hi there, as the title said, I cannot update to the recent 10.6.8 v1.1 (nor v1 for what it matters). All seems going fine till the iMac reboots, then a kernel panic is generated. Only way out is to reinstall 10.6.7 COMBO.
Both Disk Utility and Disk Warrior agree on the issue, they both say they have repaired and the iMac goes into kernel panic with again pcscd.pub block count error (should be 16 instead of 17). Re-installing 10.6.7 everything is happy again.
Any idea? Hard disk tests with Disk Warriors show nothing and the HD is journaled.

Can't get past Kernel Panic!

I left my macbook running acquistion yesterday for about 2 hours and when I returned I could not wake it from sleep. I forced a shutdown holding the power button and now every time I turn on the macbook I am instructed to restart it, in several different languages. This screen comes up just after the "ping" when I turn it on and after the apple logo appears.
So far I have tried taking the battery out and holding the power button down for 5 seconds. Resetting the PRAM with "apple" "option" "p" and "r". Restarting in safe mode holding the "shift" key. Attempting to reboot from the instal CD disk 1 holding either the "option" key, the "x" key or the "c" key - when I do this the spinning gear appears for about 90 seconds and then reverts back to the restart kernel panic screen. I have also tried starting from the power source alone without the battery inseted. No Luck. And I ran a check of the hardware, holdig dowm the "d" key on start up with the disk inserted. No problems found.
I have no other external devices attached and I have made no modifactions to my Core 2 duo macbook that I got out of the box 3 weeks ago.
I am going to take it down to the store tomorrow unless anyone can think of a fix I have not yet tried.
Thank you for your help!

Boot from your Snow Leopard DVD. If you still get the kernel panic, then you have a major hardware problem. Take it in for service.
If you can boot successfully from the Snow Leopard DVD:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Now, boot the computer into Safe Mode and operate for a while to see if the kernel panics cease. You can
Visit The XLab FAQs and read the FAQ on diagnosing kernel panics. Also, see OS X- How to log a kernel panic. Locate the panic log and post it here for us to examine.

Help, Kernel Panic transferring HD to new Intel Imac

My Imac 500 has a Kernel Panic error and I will need to get my files to my new Imac Intel. Can I do this without resolving the Kernel Panic error? Will my Intel Imac see the HD on my Imac 500 while it is in this error mode?
Any help is appreciated.

You should be able to use the Migration Assistant to move your user account to the new computer as long as there is no problem with the old computer's disk drive.
Shut both computers off and connect them via a Firewire cable. Boot the old machine into Target Disk Mode. After the TDM logo appears boot the new computer normally. The old computer's disk drive should appear on the new computer's Desktop. Open Migration Assistant (Utilities folder) on the new computer and use it to transfer your user account to the new computer.

Need help troubleshooting Kernel panics

Hi,
I have had two Kernel Panics in two days just now, and another one a few weeks ago. The logs don't help me as I am not familiar with the wording on the Mac side, and I cannot submit the error reports to Apple as it fails, probably because I run 10.5.8 and Apple discontinued suppoort for Leopard or something like that. I would need help trying to figure out from the error message whether it is likely hardware, software, network, etc.
Here are the tope lines of the recent Kernel panic logs:

The last two kernel panics happened just as I hit "send" in Thunderbird, so it may be related. I fail to understand how such a simple command would crash a computer though.

I'm trying to clean up my mailbox and when I delete an item(s) I get a message that say's "operation could not be completed- file exists. Further, when I do this one message is copied (not deleted) to the trash folder. Can someone help me through this?

I'm trying to clean my mailbox and when I click on delete or highlight and move to trash I get a message that says "operation could not be completed - file exists. Further, when I select a message or group of messages, one of them is copied (not deleted) to the trash folder. Can someone help me through this?
Thanks.

It's a POP account. I decided to clean up my mailbox today after noticing the computer was real slow after USA Today started sending their daily top stories with new graphics. Also before I noticed the problem with mail deletion - two things happened. 1) I updated security sofware as prompted by Apple and 2) downloaded Mackeeper and went throught some preliminary scans but did not buy their package. Thanks forn nstaying with me.

Somehow my iTunes app has been put into the trash. How can I get this and all of the stuff that was in it back to my Application folder? I try to drag it out of trash, but it won't work.

Somehow my iTunes app has been put into the trash. How can I get this and all of the stuff that was in it back to my Application folder? I try to drag it out of trash, but it won't work.

Also, when I do try to drag it out of the Trash to put it back into Applications (on the Finder sidebar), it asks me to authenticate with the administration password. I enter it, and then a window appears saying that I can't do that because I do not have permission to modify iTunes. Please help.

I recently changed from a Mac Pro to an iMac. A large chunk of emails have disappeared. Time Machine is no help. Any ideas as to how I can get them back?

I recently changed from a Mac Pro to an iMac. Despite using Migration Assistant, a large chunk of my recent emails and nearly all of my wife's emails have disappeared in transit. Strangely, emails from my distant past are still there. Time Machine is no help; the messages may be on my backup disc but they're behind an invisible icon. Any ideas as to how I can get them back?

Quit Mail. Force quit if necessary.
Back up all data. That means you know you can restore the Mail database, no matter what happens.
Triple-click the text on the line below to select it:
~/Library/Mail/V2/MailData/Envelope Index
Copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder
from the menu bar. Paste into the box that opens (command-V), then press return.
A Finder window will open with a file selected. Move the selected file to the Desktop, leaving the window open. Other files in the folder may have names that begin with "Envelope Index". Move those files, if any, to the Trash.
Log out and log back in. Relaunch Mail. It should prompt you to re-import your messages. You may get a warning that the index is corrupt and that Mail has to quit. Click OK.
Test. If Mail now works as expected, you can delete the file you moved to the Desktop. Otherwise, post your results.

Hey Shady K,
It sounds like you've removed the iCal and Widget icons from your dock and want to get the back there for easy access. The following document goes over dock basics and there's a section (which I copied below) that goes over how to get those icons back on to the dock. Essentially you'll just find the application's icon in your applications folder and drag it back.
Mac Basics: The Dock
http://support.apple.com/kb/HT2474
Adding and removing Dock items
If you want to add an application to the Dock, click the Launchpad icon in the Dock and drag the application icon to the Dock; the icons in the Dock will move aside to make room for the new one. If you want to add a file or folder to the Dock, just drag its icon from any Finder window (or the desktop) and drop it on the Dock. The resulting icon that appears in the Dock is actually an alias of the original item (it's kind of a pointer to your original item). If you drag an application or file onto the Dock, you'll be able to open it anytime by simply clicking its docked icon. If you drag a folder onto the Dock, a Finder window of the folder's contents will display when you click the folder icon in the Dock.
To remove an item from the Dock, drag its icon an inch or more off the Dock and wait a couple seconds, then release; the icon will disappear in a poof of smoke. There are some icons that you can't remove from the Dock, such as the Trash and the Finder.
Don't worry, you aren't permanently removing the item from your computer; you simply got rid of its Dock icon. If you want that item back in the Dock, locate the application, file, or folder in the Finder (or with Spotlight), and drag it back into the Dock.
Hope that helps,
David

Help!! I messed with 'users' under Mac HD and can't get back!!!

I got this computer from my father-in-law a while ago and went to change his username to mine. I thought i did so successfully. I also grabbed the shared folder and chucked it in the trash (something I'm sure I shouldn't have done). Later I'm browsing on Safari and it unexpectedly quit. I opened it again and all my settings (bookmarks, etc.) were gone. I restarted my computer and nothing changed. My Mail is completely reset, my address book too and who knows what else. All I want to do is go back.
Presently under users I have 3 icons:
1) first one is "Dean" with a folder icon. Dean info states that it's 1.49 GB in size and created back in March 2005
2) then there's "JON" (my father-in-law's name) with the house icon. JON info states that it's 12.3 MB in size and created last night (when all this happened).
3) lastly there's "Shared" with a folder icon. Shared info states that it's 4 KB in size and created last night as well.
Clearly the Dean folder is where all my past history and info is and is what I want back. When I click on it I get the following folders: Desktop Documents, Library, Movies, Music Pictures, Public, etc. Each folder with my personal documents, pictures etc. So it seems to me that everything is there but how do I get it back to Dean being the default user. please excuse my inept terminology and knowledge in these things. I do hope someone can help me get my safari settings, email and address book back. Thank-you.

el_dinyo,
Welcome to Apple Discussions.
You may have some opportunity to recover from your ill fated attempt to change usernames.
Please read Recover from renaming your Home folder by Dr. Smoke. Although I doubt that it will help recover items from the deleted shared folder it may restore a semblance of normalcy regarding some of your other problems.
If the files in the shared folder are critical, stop using the computer and consider Data Rescue II for file recovery.
