Question on Directory corruption

Hello,
I posted last week about my system wide crash on my PM G5. I took it to the Apple store and they diagnosed it as a fried processor. The liquid cooling had also ruptured leaking into the unit. They replaced the processor and I picked up the computer last night. I booted out of my external drive and repaired permissions on my Macintosh HD. I also verified the disk and there were no errors detected. The problem I am having is my spotlight does not seek out the files when rendering the search. For example, I searched for "system profiler" and spotlight did not show the application in its result. When I manualy opened system profiler, then spotlight was able to find it on a subsequent search. This seems to be a consistent thing with alot of program files (it won't find them until I open the file ahead of time). Otherwise, the computer is behaving ok. Does this seem to be a directory corruption of some kind??
What is the BEST way to deal with this?
Should I purchase Disk Warrior and use it. Is that just a quick fix or a permanent one?
Should I back up my data and wipe my hard drive and re-install? I don't want to have to manually reinstall my third party applications one by one. Is there an efficient way around this??
thanks for all your advice and I PROMISE I will (as I do always) grant points for helpful and solved questions

Delete the Spotlight Index files and rebuild.
I use Tiger Cache Cleaner. But a search will offer more utilities.

You don't have Disk Warrior?? shame
That and two backups (backups first, DW4 next).
Disk Utility does not find every and all errors or problems.
Add Applejack to your list of tools, too. Deleting the cache files with it improves performance and eliminates some headaches.
I probably would have erased my hard drive and done a restore from cloned backups. I repair a disk first, never bother to verify, and then run "repair" permissions.
The Mac's Finder has a real case of amnesia and deferred updating. Something that TCC can help cure by forcing the Finder to be more pro-active. Faster disk drives, more memory for caching, keeping your drives in good health.

Drobo failure & Directory corruption

Reporting my experience with a Drobo failure and great support from Alsoft DiskWarrior :
My Drobo failed. Not a hardware failure, but a corruption in the directory that prevented my disk to mount...
According to Drobo support, everything was "ok" on their side.
According to me, I had lost access to almost 3TB of data !
This was the second time a directory corruption happened to me on one of my Drobo (I've never experienced this on any other type of drive in 15 years... but according to Drobo support, it could happen to anyone...) . Therefore I was already equipped with the excellent "DiskWarrior" from Alsoft, which had already saved me once.
I was not so lucky this time : an error in Alsoft prevented the Directory to be rebuilt.
I contacted Alsoft support and I was really impressed by the service ! Marc from Alsoft took the time to remotely connect to my machine and do his magic, manually retrieving, fixing and mounting the corrupted directory. Helping me retrieve almost 2TB of data.
A couple of lessons :
- be paranoid with backups : this Drobo was storing archives of backups... I was anxious to retrieve the data, but nothing bad happened because of this failure.
- don't trust advertising : Drobo would claim that you cannot loose data. I did...
- don't name your files with generic names : when the directory structure is corrupted, and you have to manually retrieve files, you're much better off with "backup_project_20110823.gzip", than with hundreds of "backup.gzip" files and no folder to know what they are !
- when things go bad use DiskWarrior ! The software is great and the service is incredible !
A couple of questions :
- are serious directory corruptions common on non-drobo hard drives ?
- what's the best method to prevent them (hard unplug/power failures being the cause I know about). I am considering re-activating Tech Tool protection - but it's soooo slow.
- what alternatives to drobo would you recommend for archiving data ?

I started lots of corruption issues with my Drobo the same day I upgraded to OS X 10.8. See my discussion thread below.
https://discussions.apple.com/message/20518529#20518529
I logged a case with Drobo Support and they told me I was the only one having such issues.

Directory corrupted again & again

I'm having a recurring problem with directories becoming fragmented/corrupted on my old computer.
B&W G3, OS9.2.1, 896ram, 2 HD: 80G & 60G. Processor upgraded to 1GHz (PowerLogix hardware).
Original factory HD has been replaced a few months ago. Slave drive is less than 2 yrs old.
I have been using Disk Warrior to repair directories as they occasionally become fragmented. The alerts from DW, or alerts from the finder are becoming more frequent. Sometimes an app will crash/quit and I'll receive alerts re directory corrupted, or various references to file structures, trees, etc. are damaged. Restart from other volume (partition) or DW cd, run DW & aok.
But why is this occurring so frequently?
Controller card on disk going bad? Not likely, my guess, because another volume on slave drive is sometimes corrupted.
Faster processor causing problem? I was running a 900MHz proc, and had no problems. New processor going bad (early failure)?
My suspicions are system-related files, but which ones?
This is getting out of hand, I'm spending too much valuable time rebuilding directories.
Please help, this has got to stop.

While not claiming to have the definitive answer to your query, there are some observations that I can make.
Your configuration seems to be one that you have chosen for audio or video recording/editing. I sympathize with your desire for a responsive setup for that purpose, but I wonder whether you have pushed the whole just that iota beyond its intrinsic capabilities. My Beige G3 has a 400MHz processor, giving a 12x multiplier of the system bus. It has max. RAM (768MB) and two drives of 6GB and 40GB. It is supported by OS 9.2.2. With Spark 2.6 (wave editor) it is quite comfortable. Because there is another Mac with OS 10.2.8 and Spark 2.82, I push the Beige no further for the moment.
I suggest that you update to OS 9.2.2 to begin with, and go over the specification, quality and match of your RAM. I should also remove it, clean the contacts (along, not across) with a soft pencil eraser, and then blow off the detritus and clean the slots with canned air. You are operating your RAM under pressure (metaphorically speaking), and need to be assured that it can withstand the assault.
Even though the chief virtue of 9.2.x is to work with OS X in Classic Mode, there is also better stability as a standalone from 9.2.2 than from 9.2.1. If the foregoing does not improve matters, then, to the extent possible, revert to the prior state of each recent upgrade, one at a time and in the order most recent to least recent. As a reversion appears to reestablish the stability that you had or wish for, you can consider the upgrade as a potential cause of the present difficulty.
In the interests of a leaner and tighter System, there may also be some virtue in having an alternative configuration in Extensions Manager with the superfluous components disabled during your specialized work. Editing, burning to optical disk and so on are patently of continuing interest, but silly voice management may not be integral to your work, and there are many more potential candidates.

HFM Question : What could corrupt a virtual directory ?

Hello Gurus,
    Sometimes I have been facing an issue with consolidation app when opening it from workspace.
    I'm trying to load this app, in to HFM 11.1.2.2. I was able to deploy the application, however, when I try to open it from Applications > Consolidation > AGGCONS to load data I'm getting the following error :
"The following exception has occurred in DataControlFactoryImpl.createSession(): oracle.jbo.JboException com a mensagem: JBO-29000:Unexpected exception caught: oracle.adf.model.adapter.AdapterException, msg=DCA-29000: Unexpected exception caught: oracle.epm.fm.common.exception.HFMException, msg= {D0084996-C813-4113-92FA-81202489222A}1-2147023878106/09/2013 15:46:51HYPDCHFMWHCHFMCASSecurity.cpp5411.1.2.2.300.3774-2147023878006/09/2013 15:46:51HYPDCHFMWHCHsxClient.cpp526611.1.2.2.300.3774"
      I've found a possible solution at Oracle Support : Financial Management Error "JBO-29000: Unexpected exception caught..." When Attempting to Access Consolidation Administration in Workspace. (Doc ID 1457676.1). However, it's not exactly the same error, but the solution related to my issue was similar. This article state that :
"The Financial Management web server configuration does not complete succesfully, the virtual directory in IIS called "hfmapplicationservice" is not available under "Default Web Site". To resolve this issue run the EPM System Configurator and on the HFM web server and choose "Configure web server" for Financial Management product to re-create the virtual folder (hfmapplicationservice)."
      When I follow the instructions above, I've got to open up the app without any problem. But in two or three days the same error happens again.
      I'm suspecting about the user but don't know enough about Consolidation Application to affirm that.
      Then I'd like to know if would be possible some kind of a "bad app use" to corrupt some files from this virtual directory that is mapped in IIS that the only solution is recreate this virtual directory.
Thanks in advance.

Hi,

Questions on Logical corruption

Hello all,
My DB version is 10g+ - 11.2.0.3 on various different OS. We are in process of deploying RMAN on our system and i am having a hard time on testing/get a grip around the whole logical corruption... from what i understand(please correct me if i am wrong)
1. I can have a check logical syntax in my backup cmd(and that will check both physical and logical corruption)...But how much overhead dose it have, Seems to be anywhere from 14-20% overhead on backup time.
2. Leaving the maxCorrupt to default(which i beleive is 0)...if there is a physical corruption my backup will break and i should get an email/alert saying backup broke...
3. Would this be same for logical corruption too ??, would RMAN report logical corrution right away like physical corruption would do? Or do i have to query v$database_block_corruption after backup is done to figure out if i have logical corruption
4. how would one test logical corruption ?? (besides the NO_LOGGING operation, as our DB have force logging turned on)
5. Is it a good practice to have check logical corruption in your daily backup? ( i guess i have no problems for it if DB are small, but some of our DB are close to 50TB+ and i think the check logical is going to increase the backup time significantly)
6. If RMAN cannot repair logical corruption, then why would i want to do the check logical (besides knowing i have a problem and the end user have to fix it by reload the data...assuming its a table not index that is corrupt)..
7. any best practices when it comes for checking logical corruption for DB in 50+ TB
I have actually searched on here and on google, but i could not find any way to reproducing logical corrpution(maybe there is none), but i wanted to ask the community about it....
Thank you in advance for your time.

General info:
http://www.oracle.com/technetwork/database/focus-areas/availability/maa-datacorruption-bestpractices-396464.pdf
You might want to google "fractured block" for information about it without RMAN. You can simulate that by writing a C program to flip some bits, although technically that would be physical corruption. Also see Dealing with Oracle Database Block Corruption in 11g | The Oracle Instructor
One way to simulate is to use nologging operations and then try to recover (this is why force logging is used, so google corruption force logging). Here's an example: Block corruption after RMAN restore and recovery !!! | Practical Oracl Hey, no simulate, that's for realz!
Somewhere in the recovery docs it explains... aw, I lost my train of thought, you might get better answers with shorter questions, or one question per thread, for this kind of fora. Oh yeah, somewhere in the docs it explains that RMAN doesn't report the error right away, because later in the recovery stream it may decide the block is newly formatted and there wasn't really a problem.
This really is dependent on how much data is changing and how. If you do many nologging operations or run complicated standby, you can run into this more. There's a trade-off between verifying everything and backup windows, site requirements control everything. That said, I've found only paranoid DBA's check enough, IT managers often say "that will never happen." Actually, even paranoid DBA's don't check enough, the vagaries of manual labor and flaky equipment can overshadow anything.

Ipod won't sync...files/directory corrupted..

Hello,
I have been trying to sync my Ipod with Itunes and I keep getting an error message that says basically it can't sync because the files or directory has become corrupted and unreadable.
Searching other sites I see some mention of this issue for others, and suggestions that the issue is likely due to files being "locked" in the directory and once "unlocked" the problem goes away.
My issue is I am pretty computer dumb when it comes to locating directories and knowing what to look for and do once I am there. Also, the "fixes" I've read thus far are for folks running a Mac..I have a PC...any fixes for a PC?
Has anyone had experience with this Ipod issue, and can someone please explain to me in step-by-step directions how to get to the directory so I can look for these "locked" files?? Then what to do with them?
Thank you so much, any help is greatly appreciated!!
Misa

Have you connected any new USB devices recently? Has the drive letter of the external drive been changed? Have you checked the external drive for errors? Does the problem persist if you power off the computer, then restart with the iPod & your external drive as the only USB devices?

Question about replacing corrupted file in windows 7

hi,
I read in windows 7 bible that if a system file is corrupted , I can replace it with system recovery tool (at command prompt) if I have onother computer with windows 7 installed.
my question is here , if I replace any file with copy the file from computer to dvd and replac it on my computer , does the windows version must be the same for 64 bit or it doesn't a matter.
thanks
johan
h.david

Hi,
Yes, the version must be the same. You may be able to get a known good copy of the system file from another computer that is
running the same version of Windows with your computer. For different versions there may be different configuration settings in the files that you operating on which if replaced with the wrong version might cause new issues.
More information regarding How to manually replace a corrupted system file with a known good copy of the file, please check it in the link:Use
the System File Checker tool to repair missing or corrupted system files
Hope this may help

Directory corrupted cvfsck crashes

G5 Xsan RAID etc - power failure while deleting some files - when the system came back up it wouldn't mount the Xsan Volume - I tried cvfsk to repair and after a long list of repairable errors it goes into an infinite loop trying to delete a damaged inode:
"Directory entry ... is an orphan. Removed."
then
"Error: Cannot remove lookup .... entry from inode 0x2faddf2324
These two lines repeat until cvfsck runs out of memory and crashes with a bus error
Unfortunately none of the repairs listed to that point get written back to the disk so it's no safe to use.
Help!

I have never seen cvfsck do something usefull, when data goes corrupt you're toasted and need to reformat the whole volume!!!
nice isn't it?
That's why it is called a none managed cluster filesystem, when you want a managed clusterfilesystem you have to pay a lot more...

File directory corrupted

Every time I try to copy files from the library to the iPod it displays the message
"The iPod 'username' cannot be synced.
The file or directory is corrupted and unreadable."
The songs, according to iTunes, copy just fine onto the iPod despite this--I click the iPod button in iTunes and it shows the songs on the iPod. I disconnect the iPod and look on there and the songs have disappeared. I plug it back into the computer and even through iTunes it now says the songs are gone.
I've tried all of the 5 R's except Restore, there's too much invested on the thing that I'm willing to wipe it clean, so that's ruled out. Any suggestions short of that?

You might want to start pulling out those CDs, I think you need to try a restore.
If you can see your iPod in Windows when you connect it, you can try YamiPod, or other similar third party software and copy your songs back to your computer without using iTunes then do the restore.
Is there a reason you delete your library from your computer? Your current situation shows why this is not a good idea, the iPod is just not a good archive media tool. Not only should you leave the songs on your computer, I will also back them up as computers also fail.

Fix: Active directory corrupted (NTDS ISAM Database Corruption errors in eventlog)

It worked for me!
Frank Keunen
IT-Pro Evangelist :: Microsoft IT Infrastructure Engineer
Follow the procedure below to fix Microsoft Active Directory database problems (corrupted Active Directory due to e.g memory issues/disk problems):
1. Reboot the server and press F8. Choose Directory Services Restore Mode from the Menu.
2. Check the physical location of the Winnt\NTDS\ folder.
3. Check the permissions on the \Winnt\NTDS folder. The default permissions are: Administrators – Full Control System – Full Control
4. Check the Winnt\Sysvol\Sysvol folder to make sure it is shared.
5. Check the permissions on the Winnt\Sysvol\Sysvol share. The default permissions are: Share Permissions: —————— Administrators – Full Control Authenticated Users – Full Control Everyone – Read NTFS Permissions: —————– Administrators – Full Control Authenticated
Users – Read & Execute, List Folder Contents, Read Creator Owner – none Server Operators – Read & Execute, List Folder Contents, Read System – Full Control Note: You may not be able to change the permissions on these folders if the Active Directory
database is unavailable because it is damaged, however it is best to know if the permissions are set correctly before you start the recovery process, as it may not be the database that is the problem.
6. Make sure there is a folder in the Sysvol share labeled with the correct name for their domain.
7. Open a command prompt and run NTDSUTIL to verify the paths for the NTDS.dit file. These should match the physical structure from Step 2. To check the file paths type the following commands: Start a command prompt NTDSUTIL Files Info The output should
look similar to: Drive Information: C:\ NTFS (Fixed Drive) free (2.9 Gb) total (3.9 Gb) D:\ NTFS (Fixed Drive) free (3.6 Gb) total (3.9 Gb) DS Path Information: Database : C:\WINNT\NTDS\ntds.dit – 10.1 Mb Backup dir: C:\WINNT\NTDS\dsadata.bak Working dir:
C:\WINNT\NTDS Log dir : C:\WINNT\NTDS – 30.0 Mb total res2.log – 10.0 Mb res1.log – 10.0 Mb edb.log – 10.0 Mb This information is pulled directly from the registry and mismatched paths will cause Active Directory not to start. Type Quit to end the NTDSUTIL
session.
8. Rename the edb.chk file and try to boot to Normal mode. If that fails, proceed with the next steps.
9. Reboot into Directory Services Restore mode again. At the command prompt, use the ESENTUTL to check the integrity of the database. NOTE: You can use NTDSUTIL to check the Integrity, however esentutl is usually more reliable. Type the following command:
ESENTUTL /g “\NTDS.dit” /!10240 /8 /v /x /o (Note: Type the path without the quotes). Note: The default path would be C:\Winnt\NTDS\ntds.dit; however it may be different in some cases. The output will tell you if the database is inconsistent and may produce
a jet_error 1206 stating that the database is corrupt. If the database is inconsistent or corrupt it will need to be recovered or repaired . To recover the database type the following at the command prompt: NTDSUTIL Files Recover If this fails with an error,
type quit until back at the command prompt and repair the database using ESENTUTL by typing the following: ESENTUTL /p “\NTDS.dit” /!10240 /8 /v /x /o (Note: Type the path without the quotes). Note: If you do not put the switches at the end of the command
you will most likely get a Jet_error 1213 “Page size mismatch” error.
10. Delete the log files in the NTDS directory, but do not delete or move the ntds.dit file.
11. The NTDSUTIL tool needs to be run again to check the Integrity of the database and to perform a Semantic Database analysis. To check the integrity, at the command prompt type: NTDSUTIL Files Integrity The output should tell you that the integrity check
completed successfully and prompt that you should perform a Semantic Database Analysis. Type quit. To perform the Semantic Database Analysis type the following at the NTDSUTIL Prompt type: Semantic Database Analysis Go The output will tell you that the Analysis
completed successfully. Type quit and closes the command prompt. NOTE: If you get errors running the Analysis then type the following at the semantic checker prompt: semantic checker: go fix This puts the checker in Fixup mode, which should fix whatever errors
there were.
12. Reboot the server to Normal Mode. If any of these steps fail to recover the database the only alternative is to perform an Authoritative System State restore from backup in Directory Services Restore mode. For more information, please refer to the following
articles: 315136 HOW TO: Complete a Semantic Database Analysis for the Active Directory http://support.microsoft.com/?id=315136 265706 DCDiag and NetDiag in Windows 2000 Facilitate Domain Join and DC Creation http://support.microsoft.com/?id=265706 258007

Active Directory Files from the Command http://support.microsoft.com/?id=315131 BR – Frank

Frank: This procedure (with some variations required for my environment) worked
perfectly. Thank you very much.
To other readers: The procedure works, but it is a loaded gun. Be careful and methodical.
The specifics of my situation, which I offer as additional information, are:
Windows Server 2003 R2 Standard Edition SP2 with all updates.
One server, 20 clients; of course the server is the domain controller.
I suggest running the command prompt window at an elevated security level ("run as:", followed by unchecking the "restricted" box).
I also suggest changing directories to C:\WINNT\NTDS or C:\WINDOWS\NTDS, as appropriate.
Variations:
The location of the NTDS folder is C:\WINDOWS\NTDS for an install that is not an upgrade from Server 2000.
Step 9 -- the parameters for ESENTUTL are different. For the integrity check I used "ESENTUTL /g NTDS.DIT /8" as the other parameters are not available.
Also in step 9 -- For the repair step that was required I used "ESENTUTL /p NTDS.DIT /8". There was a window warning of a possible data loss, which clicking OK cleared.
Step 11 -- NTDSUTIL FILES INTEGRITY works properly without change. However, the Semantic Database Analysis check cannot be run in a single command. I used "NTDSUTIL SEMANTIC DATABASE ANALYSIS" followed by "GO" at the next prompt. The database analysis does
not report a positive result, but if there is no warning the database passes the analysis. To be certain I ran the "GO FIX" step anyway, which gave identical output.
After this procedure the system started perfectly. I recommend this procedure as the answer to the problem.

Air: Two questions about directory handling

FileSystemTreeHi,
I'm currently working on a file browser in Air 2.0.
Is there a way to get the name of a drive (for example the name of the inserted cd or the name of the C: hard drive that you can enter manually)?
And the second question is:
How can I determine if a folder has another folder inside? (I want to show a directory tree and reading and checking the content of every folder takes too much time. The FileSystemTree class simply assumes that every folder is a branch, but that leads to empty folders that can be opened.)
Thanks in advance.

Ok. I figured out how to get the name of a drive: you simply got to use the new StorageVolume classes (StorageVolumeInfo.storageVolumeInfo.getStorageVolumes()) and you got the name and other properties.
The other problem is still unanswered. So I got to check the content of a folder to be sure that there is a sub folder.

Directory corrupted

Can anyone help here. I looked for support on this but found no answers...
I restored my iPod because it froze. All the music was erased. When I went to plug it in it wasn't showing up within iTunes but the iPod had the "Do Not Disconnect" on it's screen.
I got a pop up box that said "The file or directory\iPod_control\itunes\itunesDB is corrupt and unreadable. Please run the chkdsk utility."
This is a pop up box that happens when I select a song from my library.
I selected all of the songs in my library and dragged them to my i pod and it seems to be working.

Question: a Directory Called "Previous Systems"

Today I found something really interesting in my macbook: a directory called "Previous Systems"... aparently most of the applications I have in my laptop are in this directory so it means that I have duplicated programs. As I think that it's not a good idea to have duplicated programs to save some space in my HD, I'd like to remove this sheet. Question: can anyone tell me why this directory was created and can I delete it whitout damage any other component in my computer? Thanks for the help.

Should be ok to delete.
Have a look here:
http://support.apple.com/kb/HT1545,
which says
"After installation
You might wonder "What do I do with the Previous System folder?" It may contain items that you need. To determine this, once you've finished configuring, installing, and updating your applications, you can compare the Previous System to the new System. If there are things in the Previous System folder that aren't in the new System folder, copy them over or reinstall. If you're not sure what some items are (and don't seem to need them), leave them in the Previous System folder. Once you're comfortable that you've got everything you need out of it, you can delete the Previous System folder (or leave it around if you have enough free disk space).
You can’t start up your computer using the Previous System folder, but settings, preference files, fonts, plug-ins, and other items remain available in case you need to access them (which you probably won't, if you use "Preserve Users and Network Settings")."
