Can't use normal disk repair tools on iSCSI target?

Hi all,
I wonder if anyone can help?
We are using a QNAP NAS box attached by iSCSI to a single Mac running Snow Leopard (normal not server) running ATTO's Xtend SAN iSCSI initiator to mount a single 12TB iSCSI volume.
The single volume (which is now named 'fixme') has developed some index issues that need repairing. However both Disk Utility and Diskwarrior fail when run, saying the disk could not be unmounted as it is 'still in use'.
No other apps are running (I've even tried quitting Xtend SAN) and I've been using "lsof /Volumes/fixme" in terminal to list what files are accessing that volume - apparently none. I've disabled spotlight indexing too just in case and am now stumped. I tried booting into safe mode but Xtend SAN doesn't like that (get java errors, so apparently something's not loading it needs). Tried a second mac, same result.
Basically it appears we just can't repair this volume.
Screenshot here:

Anyone got any ideas?
Thanks - Jon

Directory Damage, what can be used for Disk Repair and Virus Detection?

Hi,
My eMac is acting up. Yesterday I started getting these messages that I needed to restart my computer (message was in a brown box window with an icon of a start up button in background).
I did the disk repair using Start up CD and it came back with "invalid key......." or something like that, and when I tried to repair it, it tried to repair the B-Tree's but then said it could not repair the problem.
I have Diskwarrior 3.03 Build 39, on a CD and on my FW Ext HD, which has a clone of my Mac HD.
Diskwarrior could not produce a graph of Mac HD because the directory was damaged. When I did a rebuild it hung on step 9 comparing directories, said there was 7 million + tests. ( I let it hang on step 9 for 15 hrs. to see if maybe it was just taking a long time due to corrupt directory). I finally clicked on Skip and got to the report page. I could do a preview, but the replace button is greyed out. When I was comparing the sizes of each folder, in both preview and original, I got a can not calculate error message on a few of them. The size of Mac HD in preview compared to the one in Original was different by 4 gbs. A week ago I repaired the Mac HD and did a Diskwarrior directory repair on all my HD's.
Before I do any reformatting of HD or other drastic measures, I was wondering what is safe to use for disk repair and virus detection. I know there is Norton System Works 3.0, Norton AntiVirus and TechTool, are these the only ones? Are these safe to use? Are there any other programs that can repair directory damage?
Thank you in advance,
Deb

The long-standing rule of thimb has been that if Disk Warrior can't repair a mungled disk directory, then you're looking at reformatting or replacing the hard drive. Since this is a week-old hard drive, I'd suspect the replacement hard drive is itself bad. It might save you grief in the long run to contact the vendor who sold you the drive and inquire about their warrenty. You might want to first run the file system check utility fsck as described in Using Disk Utility and fsck
Directory repair and antivirus protection are different critters. Norton AV is mostly safe (if you don't mind it's track record of false positives) and is used by the IT department at the lab where I work. Norton SystemWorks, AKA Disk Doctor Kervorkian, is most assuredly NOT safe. For every poster reporting something nice about it, you'll find at least 2 dozen cursing it. It has a known track record of detecting problems no other utility finds and of "repairing" drives such that nothing can then read or repair the drive short of low-level reformatting (and occasionally even that fails).
Tech Tool Pro 4 has a good reputation, as does Drive Genius. Tiger OS X 10.4.2 and later include a version of Disk Utility that can for the first time also make effective B-tree and keys out of order and overlapped extent repairs. Still, my personal gut feeling is that if Disk Warrior is choking on the hard drive, you're looking at reformatring while zeros the drive (zeroing should detect and map out bad physical secotrs).
You can also refer to Disk First Aid: What to do when it finds an error and to Handling "overlapped extent allocation" errors reported by Disk Utility or fsck

I hate to have to tell you this, but backing-up that way is unreliable and not supported by Apple. See: Using Time Machine with an Airport Extreme Air Disk.

Most likely, you got this message before all this started:
What that doesn't explicity say is, the backups failed the verification. When that happens, Time Machine marks the sparse bundle as damaged and won't back up to it anymore (even if Repair Disk can't find the problem). See #C13 in Time Machine - Troubleshooting for details.

Can I use remote disk on a 2008 unibody MacBook with no optical drive?

According to the link you came from the only MacBooks this works with are MacBook Air and MacBook Pro with Retina display. If yours is not one of these I can see no harm in trying it.
You could consider getting an external optical drive.

NO.
You have to use Windows or a Windows utility.
There are programs that will clone an entire drive (sector) as well.
DU does not though. Paragon does support Boot Camp.

As far as we know, Time Machine cannot write to a disk image. It needs to write directly to the Time Capsule disk.

How can I use remote disk?

I just installed bootcamp on my Macbook Air. How can I use remote disk so that I can put a disc in my Mac Mini and use it in Windows 7 on my Air?

Can't use Install Disk to repair my MacBook Pro HD

Hi,
I ran the Mac Disk Utility on my MacBook Pro's HD and I got this screen:
http://i99.photobucket.com/albums/l320/brunotapia/help.gif
[IMG]http://i99.photobucket.com/albums/l320/brunotapia/help.gif[/IMG]
So I inserted the install disk so that I could boot up from the CD and run disk utility to repair my HD.
But the MacBook Pro keeps spitting out the disk. It reads other disks fine and this install disk reads on my friends computer so I know that both the MacBook Pro drive and the install disk are ok. So what could be causing my problem?
I have also tried to boot the computer from the disc holding the "C" key down, but the computer spits out the disk and boots up from the HD.
How can I repair the HD if I can't get the OS to boot from the install disk? What else can I do? Can I boot from another HD or Thumb drive? How about an iPod?
Any information would be greatly appreciated.
Bruno

Are you using the OS X Installer Disc One that came with your computer? To startup from the installer disc first insert the disc in the optical drive (label side up.) If the computer does not allow the disc to mount on the Desktop then either your optical drive is bad or the installer disc is damaged or is not a valid installer disc for your model.
If the disc mounts on the Desktop then restart the computer and after the chime press and hold down the "C" key until the spinning gear appears beneath the dark gray Apple logo.
If this still doesn't work then boot the computer into single-user mode by restarting and after the chime press and hold down the COMMAND-S keys until the computer starts up to a black screen with white print. At the prompt enter or paste in the following:
/sbin/fsck -yf
Press return and wait. If you receive a message that the drive required repairs, then re-run the above command line until you receive a message that says the filesystem is OK. If you have to repeat the command more than seven times without receiving a filesystem OK message, then that means the drive cannot be repaired by fsck. If you have a utility such as Disk Warrior 4.0 or TechTool Pro 4.5.2 then you can boot from their CDs and attempt to repair the drive. If either or both fail then the drive will need to be reformatted.
I highly recommend backing up.
Yes, you can boot from any external drive provided it has a bootable copy of OS X installed on it. If you have a second Mac with Firewire ports then you can connect it to the MBP via a Firewire cable. Boot the MBP into Target Disk Mode and the other computer normally. The MBP's hard drive should appear on the other computer's Desktop. You can then repair the drive using Disk Utility or other disk repair utility.

Hi Smart71,
I know it sounds complicated, but it really isn't.
You need to select the option to manually edit the disk label
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.

Can you use other disk drives on mac mini rather than the superdrive?

I have just purchased a mac mini and am exploring the various options available to me regarding disk drives?
Are you limited to just the Mac Superdrive or can you use other makes and models?
i read somewhere that some drives will only let you install software and not let you Burn Music or play games?
Is that correct.

I have three firewire burners daisy-chained to the mini for ripping my CD collection.

Can We use FDM as ETL tool between SQL and Oracle

I want to use FDM as ETL tool between SQL and Oracle. Can it be possible. I didn,t found any target adapter for oracle database.My source system is SQL and Target system is Oracle database.
Rahul
Edited by: user12190125 on Nov 9, 2009 4:23 AM

Rahul,
I believe this is possible to do, but not an easy one and there are a few considerations:
How much data are you processing? FDM has a lot of features which support the business process. While this is great for users and audit trail etc. it slows down performance if you want to process a lot of data. It also depends on the type of mappings you use (Like mappings are slower than explicit mappings).
How familiar are you with VBScript? There is no explicit target adapter for Oracle, but there is a data mart adapter which can be used for anything. You have to implement everything yourself though, mainly the Export and Load actions. In there you will also have to handle the the connections to the MSSQL and Oracle databases.
Check the data mart adapter and see if you feel comfortable with defining the vb code in there. There are reasons for and against this approach. ODI would probably be the better choice unless you really need to have FDM's process support.
Regards,
Matt

Can I use recovery disks on a new hard drive on a dv4?

I know the hard drive is toast in my dv4. Can I use the recovery discs I made when I got the computer to load a new hard drive?
This question was solved.
View Solution.

Yes you can. That is the purpose of having the recovery media.
Replace your hard disk with one that is of equal or larger capacity. That does not mean use a larger than 750 GB hard disk unless yours had one installed when delivered.

No files appear but disk space is used. Disk repair?

Hey all, I've seen one or two people with similar problems but couldn't find a resolution. The iPod seems to be nearly full but the songs I placed on it appear not to be there. New songs that I transfer show up all right though.
Can you run disk repair programs on iPods? I tried to run Disk utility but I got some error message about the drive not unmounting. I just want to know if there is some mechanical problem that I should get repaired or if I restore the iPod will the problem go away permanently? Thanks.

That happened once when I had a nano that I was updating to 1.2 firmware. My computer stopped working halfway through, so there was an nano with music on it that wasn't visible. I got rid of it by switching the nano to disk mode,and wiping it clean before running the cd that came with the nano. But a restore works better.

Form - Can not use the Text Edit Tool in Adobe 9

Hi,
I was wondering if someone could please assist me, I have created a form but the text editing tool is coming grayed out, how am I able to get this function back?
I simply need to remove one word and am unable to do so. It tells me that some functionality is restricted for extended features and to save a copy. but when i save a copy I am still unable to use the touch up tool.
My Thanks in advance for your assistance.

My guess is that you did use LiveCycle Designer and are not aware of that. Designer is accessed from Acrobat in the forms menu and may have come up even if you were not aware of it. If that is indeed the case, you can only edit the text in Designer.
If it is an AcroForm, then it may be that you have activated Reader Rights or such. To remove Reader Rights, there is a specific procedure to use and unfortunately I do not remember it. If you have Reader Rights activated, indicate that and someone should be by that remembers how to remove the feature so you can edit the document. The removal is not as simple as one would think, but is rather straight forward. It involves saving or such -- I just don't remember and it is not something I am finding in the help menu.
