What do do when disk utilities fail?
Hi. I have an iBook that has been switching back and forth between OS X 10.3.5 and OS 9.2.2 pretty smoothly (recently replaced the DC-in board).
One of the OS 9 programs (Pro Tools) is crashing and giving me an error message saying I need to defragment. Running Norton Speed Disk optimizer in OS 9 normally takes care of this problem. But now, at around the 3/4 complete mark, I get an error message saying the disk is damaged and needs repair. When I run Norton Disk Doctor, it eventually returns an error message saying it can't repair the disk -- too bad.
I have already run the OS 9 Apple Disk Utility and, on the OS X side, repaired the disk permissions. What now?

Okay -- so DiskWarrior ties up your computer for 2 weeks while it does it's thing?
If your hard drive directory is disastrously scrambled, DW can take days to sort things out, but in 95%-99% of all cases it takes oonly a few minutes. Norton Disk Doctor is perfectly capable of scrambling it disastrously, but if your Mac still starts up and runs, things probably aren't that bad yet.
A damaged directory makes it likely that there will be some loss of data if you simply copy the entire drive to a backup disk now. The bad directory means the OS can't properly locate every file that it knows is supposed to be on your hard drive, so some of them aren't going to be copied properly. It might be just one insignificant file, or dozens or hundreds of important ones, that are damaged in part or lost altogether in backing up. The ideal time to back up your drive is when you know it's all in good order.
Erasing your hard drive will also erase the bad directory, so it's an alternative solution to the problem if your data is already backed up. Copying the contents of a backup that you make now, with a damaged directory, back onto your internal drive after erasing it won't fix any files that have already been corrupted, but it will at least copy everything — damaged or not — back into a new, undamaged directory.

Is RAC node configuration when disk array fails on one node .
Hi ,
We recently had all the filesystem of node 1 of RAC cluster , turned into read only mode. Upon further investigation it was revealed that it was due to disks array failure on node 1 . The database instance on node 2 is up and running fine . The OS team are rebuilding the node 1 from scratch and will restore oracle installable from the backup .
My question is once all files are restored :
Do we need to add the node to the RAC configuration ?
Do we need to do relink of oracle binary files ?
Can the node be brought up directly once all the oracle installables are restored properly or will the oRacle team require to perform addition steps to bring the node into RAC configuration .Thanks,
Sachin KHi ,
If the restore fails in some way . We will require to first remove and then add the nodes to the node 1 cluster right ? Kindly confirm on the below steps.
In case of such situation below are the steps we plan to follow:
version ; 10.2.0.5
Affected node :prd_node1
Affected instance :PRDB1
Surviving Node :prd_node2
Surviving instance: PRDB2
DB Listener on prd_node1:LISTENER_PRD01
ASM listener on prd_node1:LISTENER_PRDASM01
DB Listener on prd_node2:LISTENER_PRD02
ASM listener on prd_node2:LISTENER_PRDASM02
Login to the surviving node .In our case its prd_node2
Step 1 - Remove ONS information :
Execute as root the following command to find out the remote port number to be used
$cat $CRS_HOME/opmn/conf/ons.config
and remove the information pertaining the node to be deleted using
#$CRS_HOME/bin/racgons remove_config prd_node1:6200
Step 2 - Remove resources :
In this step, the resources that were defined on this node has to be removed. These resources include (a) Database (b) Instance (c) ASM. A list of this can
be acquired by running crs_stat -t command from any node
The srvctl remove listener command used below is only applicable in 10204 and higher releases including 11.1.0.6. The command will report an error if the
clusterware version is less than 10204. If clusterware version is less than 10204, use netca to remove the listener
srvctl remove listener -n prd_node1 -l LISTENER_PRD01
srvctl remove listener -n prd_node1 -l LISTENER_PRDASM01
srvctl remove instance -d PRDB -i PRDB1
srvctl remove asm -n prd_node1 -i +ASM1
Step 3 Execute rootdeletenode.sh :
From the node that you are not deleting execute as root the following command which will help find out the node number of the node that you want to delete
#$CRS_HOME/bin/olsnodes -n
this number can be passed to the rootdeletenode.sh command which is to be executed as root from any node which is going to remain in the cluster.
#$CRS_HOME/install/rootdeletenode.sh prd_node1,1
Step 5 Update the Inventory :
From the node which is going to remain in the cluster run the following command as owner of the CRS_HOME. The argument to be passed to the CLUSTER_NODES is a
comma seperated list of node names of the cluster which are going to remain in the cluster. This step needs to be performed from once per home (Clusterware,
ASM and RDBMS homes).
## Example of running runInstaller to update inventory in Clusterware home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORA_CRS_HOME "CLUSTER_NODES=prd_node2" CRS=TRUE
## Optionally enclose the host names with {}
## Example of running runInstaller to update inventory in ASM home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ASM_HOME "CLUSTER_NODES=prd_node2"
## Optionally enclose the host names with {}
## Example of running runInstaller to update inventory in RDBMS home
$CRS_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=prd_node2"
## Optionally enclose the host names with {}
We need steps to add the node back into the cluster . Can anyone please help us on this ?
Thanks,

What to do when fingerprint scan fails during checkout?
I've successfully used Apple Pay about a dozen times already - always very easy.
Last night, I was at the checkout at Subways (where I previously purchased stuff with Apple Pay) and tried to pay with Apple Pay. For whatever reason - maybe I held the phone different or my thumb had some moisture on it - the fingerprint scan did not complete (the picture of the fingerprint didn't fill in completely) and Apple Pay seemed to "give up". It just sat on that screen and no matter what I did with my thumb, nothing would restart the payment. There was no button or link that said "Retry". Neither I nor the cashier had any idea what to do. I pressed the home button and held the phone close to the terminal again - but no Apple Pay transaction screen came up. The cashier then pushed a couple buttons on her terminal to put it into "Mobile Phone" payment method - which basically just caused a QR code to show up. I told her that this was not the right thing - she should go back to "Credit card" payment. When she did that, the little "wifi" logo re-appeared and I held my phone close to the terminal again. This time Apple Pay showed up and I was able to authenticate/pay.
I wonder what happened. Did my phone give up on the transaction or did the store's terminal? Or something else? If this happens again in the future, what should I tell the cashier to do - in a language he/she'll understand?
Thanks,
TomThe problem is that there are not a lot of employees of places that accept and type of mobile payments that know about it or what to do. If you ask about Apple Pay or mobile payments, most give you a blank stare and shrug their shoulders. It's hard to say whether this was a problem on your iPhone or a problem from Subway. Either way, if you encounter this issue again, the merchant will want to keep it as a credit card payment.

[SOLVED] Disk check failed at boot.
Hello,
I've got a problem with arch booting. It looks like my cpu doesn't like being left alone fat night. I powered it on today and what I get iss disk check failed error and reboot message. I've tried fsck-ing all partitions and everything seems to be allright. What's more I can mount everything when press ctrl+z when arch tries to reboot and system loading goes on. Any tips? What should I post?
Last edited by muchzill4 (2010-02-05 10:02:48)You have some messed up file systems. As if you didn't know.=O)
Have you changed fstab? Switched disks around? Try using uuid in fstab instead of '/dev/sdxx'.
Check this thread http://bbs.archlinux.org/viewtopic.php?id=89857
and use

How do I restore my tabs and windows, whether open or closed, when everything else fails?
This is not so much a question, as an answer that some people desperately need.
Ever since Version 34, Firefox has done a superb job of restoring the tabs that the user has created, either on restarting Firefox (if that option is chosen) or on request.
The details of how to restore tabs are covered in Firefox's basic help online, and even how to deal with several crashes in a row (such as in an addon) ruin the normal backup file are also well explained.
However, today I accidentally pressed Alt+F4 twice on my poorly-designed keyboard and closed my main window, with 93 tabs, and another Firefox window as well. I'm not sure this is exactly what happened, but I lost all 93 of my tabs.
I read many of the postings in which people give various suggestions, but none worked. Every time I restored a version of the sessionstore.js file I saw the same lonely empty tab. Restoring prefs.js did nothing, and neither did making changes in the internal configuration constants.
I tried refreshing/resetting Firefox (which preserves bookmarks), but I still couldn't restore the tabs. It was now clear that the problem was in sessionstore.js (and all its backups) for sure.
I'm writing this for people who must restore their windows or tabs, and don't mind getting technical about it. That was my situation.
The solution was to realize that the sessionstore.js file contains JSON code, which is an efficient way to represent integers and strings arranged in a tree structure.
I figured there must be a JSON editor somewhere, and it turns out there is a great one available online, at www.jsoneditoronline.org . It can read a file on your computer, edit it, then save it back on your computer.
As soon as I viewed sessionstore.js in the editor, it was obvious how easy this was going to be. The top level of the tree is understandable. I simply grabbed the data representing the window with 93 tabs, and dragged it from the list of closed Firefox windows to the list of open windows. This automatically moved the history of each tab, and even the strings entered into forms.
After copying sessionstore.js back to the Firefox profile, I started Firefox one more time. The playing of Pandora signalled that my tabs were back and functioning once again.
Now, editing JSON code is not something that everyone is ready for. And your problem might not be reflected in the JSON tree so simply. But, for technical-minded people who don't want to lose their tabs or windows to a mistake or a crash, this technique can be just what's needed when everything else fails.That sounds very handy. Nice going. A kind of backup would be to
create a folder in the Bookmarks Manager, and keep a list of links there.
Just one note. The sessionstore file shows the last windows / tabs that
are open. Because the window with the 90 tabs was closed first, then the
other, that is what caused your issue.

It would be useful to you if they had a different name, but the computer knows they are different. Create separate sync playlists for each device and go to the Music tab when it is connected and specify which playlist should be used for the sync.

Precisely why it's not an iPad, and why it doesn't cost very much. An Apple rep would tell you how to connect an iPad to every computer.

I have a WD Passport HD attached to my Mac. When it was last connected it went into sleep mode and ran out of battery. Now I cannot find my HD in Finder and Disk Utilities is telling me it cannot repair the HD. I can see the HD but the volume part is greyed out. Any ideas on how to recover my data?
There are other methodologies of scanning a HD
which involve data extraction, but loss of metadata is often the result if the directory is corrupt.
Metadata is the info on what the data IS.
Like having all your papers thrown in the air, its all there, but just a giant mess.
This is why you always always must have several external HD redundancies of your data. One isnt enough, neither is two really.

What does it mean when one gets a message that Time Capsule or its disks are failing?
What can be done about it, if it's a reparable situation?Thanks for the info.
I will look into buying a large external hard drive as an option. But given that I can't seem to back up anyway, is there another option other buying another Time Capsule? Do any of the external hard drives have embedded intelligence that allows them to work off my other router.
