Fixing stupidly long ReiserFS mount times

Here's something interesting - the reason for ReiserFS's long mount times. Apparently there is some caching going on on mount, slowing things down; there's a patch to get rid of this (endorsed by Hans Reiser, though he was at first opposed to it), but it seems to be a -mm kernel thing. Perhaps the patch ought to be included in the stock kernel, or at least in -beyond? Or do you guys think that such minor patching would be a bad idea?
(You know, it would have been nice if this had been implemented as a mount option... "nobcache", perhaps, or maybe have "bcache" and make no on-mount bitmap caching the default.)

A description of what you're speaking of might help too... 'long mount times' means nothing.
Actually, it's the perfect description of the only real downside of Reiser36, mount times that go up with partition size, in a linear way. Mounting a 150GB partition on a modern hard disk takes about 7seconds.
I tried the beta version of Jeff's patch sometime ago, I'm glad there's a stable version available now. I'm not sure if patch no. 4 is usable without the other 3, but it's worth keeping an eye on.
iphitus wrote:Alternatively, fix the actual problem and just use a better filesystem.
Let's not go into another "which filesystem is best thread". Ext3+dir_index and Reiser36 are on the same level, speed-wise. Only Reiser36 uses less space (yes, that's with tail packing disabled).

Can't mount Time Capsule on PC (white system tray icon no longer there)

My new time capsule is working perfectly on my MacBookPro, however recently I tried to get it to work on my PC laptop. I easily got the wireless internet work on the PC, that's not a problem. I installed the airport utility on my PC and it was able to recognize it through the airport utility interface/configuring window where I could change settings, etc., just like I could on my Mac. There used to be (on my PC) this white icon in my system tray on the lower right of my screen. When I clicked on this I could type my password, as prompted, and mount to the time capsule, which I could now see in My Computer as a drive. I tested a few files by dragging them over into the drive, and it worked fine. Now, a week later the icon in the system tray has disappeared, and I can no longer see the time capsule on my PC in My Computer. I can still click on the airport utility icon in my programs and see/change settings in my time capsule from my PC, but cannot see nor access the drive from My Computer (or mount by clicking on this now missing icon). Anyone else know what I can do? Thanks in advance!

I was just having this problem and figured out that the white system tray icon is the Airport Base Station Agent. It wasn't running for me for some reason, too, but I found it and started it back up again at C:\Program Files\AirPort\APAgent.exe.
Here's an Apple Support article (it's a little old) I found that discusses drive mapping in windows with the Airport Base Station Agent: http://support.apple.com/kb/HT1331
Hope this helps.

With OS X10.9 the Mail window (after hitting reply or forward) grows ridiculously long, sometimes 4 times the width of the screen and would not allow me to readjust the window size. Any one has the same problem? How shall I go about fixing it? (Thanks)

I'm having the same problem. I've tried going into the Library and deleting the mail plist file(s), which fixes the problem, but only temporarily. Would appreciate any help here too!

TS2655 imac can no longer find the time capsule to add it...how do i fix this

my imac can no longer find the time capsule....i had to delete the old network and re add the time capsule to create a new one and now the imac keeps searching for the base and cant locate it

If you mean that Time Machine can't find the Time Capsule, I'd try using the Time Machine panel of System Preferences to redeclare your backup disk. If that's not what you mean, please explain.

La Cie Porsche Design External Hard Drive no longer working with Time Machine since update to Yosemite.

My La Cie Porsche Design External Hard Drive USB 3.0 is no longer working with Time Machine. Is Yosemite the cause? How do I fix?

Can you see the drive in Disk Utility? If so, try selecting it and using the Mount button in the top menu. You can also run repair disk and repair permissions.

Lion won't mount Time Machine backup, but...

My Time Machine back up to an external drive seemed to have failed. It won't mount on Lion long enough to fix the problem. Other times it just locks up.
I dual boot with Vista and it sees the drive and all the files just fine. Any idea of what I can do to mount it on Lion. I'm tempted to just format it in Vista. Mount it in Lion, if it does at all, then format again for OS X. See if just a corrup files and not a failing hard drive.
Any suggestions are appreciated.

Sounds like a problem with the drive itself, but might be corrupted data. See if you can Repair it, per #A5 in Time Machine - Troubleshooting.

If you do that, format it again with Disk Utility. Among other things, be sure it has the GUID partiion map scheme, not MBR (the Windoze setup), or even a version of GUID set by Windoze.

After port forward, airport utility can no longer see my time capsule

I tried to forward public port 1025 to private port 80 on a raspberry pi using airport utility. But after I did that, the airport utility can no longer see my time capsule. Wifi still works correctly. Are there any conflicts about port 1025? How to fix that other than resetting the time capsule?
Thanks,
Michael

It doesn't sound like a port that is used.
From the standard google search.. nope.
Reboot the whole network..
No luck tell me what OS version you are running the utility on and what model and firmware TC???
Note with Yosemite, anything can and will happen.

FIX the long backups, not disable them. Solution is here!

NOTE: This process was performed on an iPod Touch 2.0.2 with iTunes 7.7.1.11 on a PC running Windows XP. The process is the same (or similar) for the iPhone.
+*My backups used to take 4 hours. Now they take just minutes, even with 40+ apps*+ installed including large apps like Texas Hold 'em, Brain Challenge, and Vay. No, I am not exaggerating. A fresh sync generally takes no more than 5 minutes from the time I plug my iPod in to the time I disconnect.
I do not guarantee this process will work for you. I can't do that. But it has worked for a lot of other people. This fix is an adaptation from geauxracerx's solution posted here. Read what others have said. I do not take credit for the solution, but I added in a few steps and gave a little more detailed info to fill in the blanks, fix problems and answer the questions I ran into when following geauxracerx's instructions.
Extraordinary long backups are caused by an error when an app (or apps) was installed or updated, particularly if you have ever installed or updated using the App Store on the device itself rather than iTunes. Even if you were never aware that there was a problem, they can arise and will cause problems with the backup process. Maybe you did have a problem during an update or install. Maybe the update stalled, or the App Store crashed. These issues are very likely what have been causing your long backups and you didn't even know it. During the backup process these errors cause it to drag and pause for a very long time before it gets moving again. From your view, you just see a normal backup that is taking hours, and undoubtedly annoying you to no end. On the inside, iTunes is trying desperately to get past a roadblock that it doesn't know where it came from.
This is how to fix the problem. *This is not a quick fix, but it is an effective fix. And it is a FIX, not a band aid.* Depending on how many apps you have installed, this can take several hours to complete. *You will also lose all game scores and any other data stored in your apps.* You will be starting fresh. It is an inconvenience, but in the end, you will be rewarded with quick, efficient backups, the way Apple intended. And you will never have to dread the
iTunes backup again.
The Process:
1. Open iTunes, go to Edit>Preferences>Syncing and remove all previous backups. Also click "Disable automatic syncing for all iPhones and iPods"
2. In your system file structure, locate the backup files for iTunes.
On Windows: C:\Documents and Settings\USERNAME\Application Data\Apple Computer\MobileSync\Backup
On a Mac: Users/YOURACCOUNT/Library/Application Support/MobileSync/Backup
Delete ALL files and folders inside the Backup folder.
3. Plug in iPod. On the Applications tab, uncheck sync apps. Click sync. This will remove all apps on your iPod, it will also backup the ipod. This backup will be very fast, and will recreate the backup folders you deleted in
step 2.
4. If there are any apps left on your ipod, touch and hold the icon until it starts to wiggle, then touch the X to delete the app. Delete all apps left on your ipod. Then sync again.
5. After the sync is complete, disconnect the iPod and do a hard restart by holding down the sleep/power button until the slider appears, slide to power off. Wait 5 seconds and push the power button again and wait for the ipod to boot up.
6. Now begin adding apps back to your ipod one by one. On the Applications tab, click "Sync applications" AND "Selected applications".
7. Click one app and sync. After the sync is complete, right click on your ipod under Devices in the left column of iTunes. Click "Back Up" and allow the backup to complete.
8. Repeat step 7 for each app you want to install. Be sure to backup after each install. As you add more and more apps, the backup will take longer and longer as the process scans apps for changes. An initial backup can also be long for a particularly large application. However, ONLY the initial backup after you install an app will take a long time. Subsequent backups are very quick. Even these "long" backups are just minutes long, sometimes up to 15 minutes in my experience.
9. When you are finished installing and backing up all apps, go to Edit>Preferences>Syncing and enable automatic syncing for all iPhones and iPods.
10. Unplug and plug your device back in just for kicks. Let it back up and sync. Better?
Notes:
The very first time an application is backed up, all critical data is written to your hard drive. This is why the backups are so long the first time. Afterward, only data changes are written, so backups are much shorter.
Backup times will continue to vary based on how many apps were altered since the last sync. If you've used one app since the last backup, your backup will be very short. If you've used 20 apps, the backup will be longer. But you will be rid of the dreaded hour (or more) long backup, that is a promise.
Now that your apps are installed and backing up correctly, the number one rule is to *never, ever install or update apps through the App Store on the iPod*. ONLY install and update through iTunes, and backup after every install or update. The App Store on the iPod is still unstable and can cause lock ups, crashes and freezes. And it is the culprit in these long backup times. Avoid it until the bugs are ironed out.
Also, do not be tempted to disable backups using programs or code edits available online. Your backups are crucial in the event of a restore. Backups contain all of your personal data like game scores, notes, icon arrangement, application data, etc. And it's not a matter of if you'll have to restore one day, it's when, and you'll be glad you have a backup when you do.

Thanks for your reply, the trackpad is 9 months old, but it was a christmas present so I dont have the receipt.
Also Im in Dubai, which pretty much means that your warranty lasts as long as they remember your face in the shop buying it!
I have read through over 10 pages of people with the same problem as mine here on the support site, the only variable is different solutions
work for some people, and nothing works for others.
I found turning my iPhone off fixed the problem for 2 days!!
Most people seem to only have the issue with Mavericks, and a few suffered with the Lions.
The movies are playing fine, they just keep pausing and playing continuously from phantom clicks.
Its got so bad now, I dont even have enough control to restart the machine!
I would simply chance buying a new trackpad... but after I received a phantom click about 20 seconds AFTER the pad was switched off, I dont wanna go throwing more money at this needlessly.
I wish Apple would take these sort of things seriously, if I cant get this sorted in a week, Im gonna have to either upgrade my Macbook to Mavericks (which I did before, then spent 2 days reverting back to Snow Leopard)
Or im gonna have to buy a PC and Cubase!
If any one at Apple is reading this (I do believe I just heard an echo!) Some of us rely on your equipment for work, and we do seem to pay a very big premium just for the privilege of the little white logo.
Is there any chance you could show your existing users a hint of respect or common courtesy by taking these issues seriously?

Laptop no longer can mount my external hard drive

After updating to Mavericks, my laptop no longer can mount my external hard drive. What on earth is going on here and how can I fix this?

The drive is spinning and I was using it the night before I updated my macbook. It is viewable in disk utility but not in finder, and attempts to mount it are thwarted. The problem is literally coincident with updating the mavericks. When I click verify it didn't appear to have any problems but I will retry when I am back at home and report the findings.
It is a Toshiba 1GB external hard drive and has adequate power. Lights are on, etc.
I have not checked on another computer as do not have one available, but that will be my next step.

I'm not sure what you mean by the times get switched around, but you migh check on both mac and device in the Time & Date section of preferences/settings to be sure they are both in the same time zone.

Long bios load time with gtx970 - maybe need gpu bios update?

I just installed my gtx 970 and it all runs fine. However I get a very long bios load time on boot up. Normally it only takes a second or two with a single beep. With the 970 though I get the single beep and the bios load screen, but it sits at that screen for a long time, then another beep, waiting, eventually another beep, and after some more waiting windows will start to load.
My problem is that now I can also no longer get in to the bios. I have tried even plugging in a ps/2 keyboard to see if maybe that could get me in. The farthest I get after hitting delete to enter is I just end up at a black screen. My mobo has no onboard gpu output, so its not like its trying to go to a monitor I cant see.
So would any gpu bios updates fix this? I am currently at the latest bios for my board which updated it to a uefi bios.
cpu: i7-2600k (yes Im aware I will only have pcie2)
mobo: gigabyte z68 d3-b3
ram: 16gb
gpu: MSI gtx 970 Gaming (previous was an evga gtx 660)

Under bios features, is there a option called boot mode select?
Try to switch to "legacy only", save and reboot.
Are you using HDMI connector? Try to use DVI.
Sorry for my english!
I dont remember seeing any boot mode select. As far as connections I am using all DVI for my monitors. I have also tried only having a single one connected in case there were issues with multiple monitors
Quote from: Svet on 02-January-15, 10:56:46
with those old boards, you need ME8 to works with modern cards
ask gigabyte support about it
Thanks Ill try emailing them. Is ME8 some other bios? Just never heard of it before
-edit
After reading up it looks like it was just a revision to allow ivy bridge devices, which happened a long long time ago on a bios update:
Support Intel 3rd generation 22nm E1 stepping CPU (Ivy bridge)
Improve power on issue
Update ME / CPU code
Unless theres something else Im missing about ME8

The pinwheel is spinning for longer and longer periods of time. Have to manually shut off iMac sometimes to get it to restart.

The pinwheel is spinning for longer and longer periods of time. Why and what do I need to do about that?

You have 10.6 on that machine, I suggest you stick with it for performance, third party hardware and software reasons as long as possible.
Consider 10.8 (not 10.7) when it's released, because 10.7 and 10.8 will require a new investment in software and newer third party hardware as it requires newer drivers the old machines won't have. (forced upgrade because of software, really nice of them)

Display Data on waveform chart or XY graph over a long period of time

Display Data on waveform chart or XY graph over a long period of time
Can anyone help?
I am acquiring data from an Ni DAQ card with the following parameters - sample rate = 12800, number of samples = 4096. I want to extract order information so as to track changes in the amplitudes of certain frequency harmonics. So I use the sound and vibration toolkit to extract this information as shown in the attached Vi. I will like to plot the resulting amplitudes against real-time starting at the time the Vi was run. I really want the display to show these changes over long periods (eg. days, months and even years).
Problem.
I have tried to plot the Y component of the resulting magnitude for a given order on a waveform chart. My choice of the waveform chart is because I also want to display alarm limits (using the mask and limit vi) (I can't have these lines displayed on an XY graph plot). I tried adjusting the scale offset using the property node and setting the offset to current time. However, the display on the X-axis can only show a span of 2 minutes as will be seen when you run the attached vi. I want the time display on the x-axis to be over a period of days, months and even years. Is there a way to set the maximum scale on the x-axis to be say a year or so in future.
I really want the display to be like the one in in the second attachment.
Attached is a sample VI created using an Ni USB 9234 DAQ card. Any card will do but I am only getting the signal from one channel for this example
I will appreciate any help that can be given to me.
Thanks

Long term testing can be tricky- and we'l get into that later. Lets start with the basics that you have wrong.
The vi as you have constructed it has only one memory element, the chart history length (default is 1024.)
You can change the number of points the Chart will remember by Right-clicking the chart an select Chart History Length from the menu.
But for a long term test - and one where you want to REMEMBER the first value you need a memeory element that is independant of the application. Your PC WILL loose power or need to be rebooted eventually. Heck it might even need to be replaced! you really need to store your data in a file. Preferablly in a file that is backed-up on a regular basis so you don't lose every point of data if the PC dies. It realy hurts when you have to restart a 2yr test because you've lost the 18months of data you collected.
For an application like this I would seperate my "collection" and "Evaluation" operations.
Have one vi that takes the reading and writes it to a file at a configurable rate You may want 1reading per minute for seveal days then 1 per hour for a few weeks- then maybe only once or twice a week for the next couple of years since you are looking for LONG TERM stability. having too much data to evaluate can take a lot of digging to find the few things that interest you (but always take more that you think you need)
Have another utility that COPIES the files, reads them and displays the data you are interested in that day. The data you want to look at won't change over time HOWEVER, you WILL want to analize it in different ways depending on what the data trends look like. Having seperate routines for collection and display allows you to update the display style and analisys without even stopping the collection vi (much less editing the vi)

I am using my Ipad on a remote craftshow site and am having problems with battery lasting 8 hrs. Can I use a 12v rv battery to recharge it or atleast maintain the charg over longer periods of time? I have a dc adapter. thanks

You should be able to use the battery if you get a car type charger which recharges mobile devices.
The full size iPads use a 10-12W charger, whereas the mini uses a 5W charger. Many car chargers only supply 5W. But at 5W, the car charger should give you some extra time on your iPad. It would be best to use a 10-12W car charger.
