Partition corruption (not physical) - due to Gnome?

Hi, a bit of lengthy background.
I use Arch 64-bit with awesomewm on my laptop with no problems. Two days ago I decided to also install Arch (32-bit) on my desktop workstation, partly to have fun with the new installer, partly to setup remote SSH access to backups, things like that. I set up the system and installed Gnome for ease of use (it would mainly be a console machine anyway) as well as VirtualBox to boot my existing WinXP install for work use. The problem (detailed below) started happening when I first set up my VM, and after some trial and error I found it would happen even without starting VirtualBox up. I then reformatted the partitions and reinstalled 64-bit Arch (easier because I already had cached packages from my laptop). Same symptoms. Previously both installs were ext4 for / and /home, I also tried replacing btrfs for / and /home, no difference. ONE time I got these symptoms for / (not /home) partition. Now I've installed XFCE and till now I can't replicate. At this point in time, / is btrfs and /home is ext4. If I go an hour without the problem I'm replacing /home with btrfs.
The problem:-
1. On starting Gnome up, everything works. I have full rw access to / and /home partitions
2. After some amount of time with some applications open, I start receiving error messages about the /home partition being mounted read-only
3. If I reboot after (2) happens, obviously there's fsck-ing needed. On ext4 the errors went something like "inodes that were part of a corrupted orphan linked list were found". I couldn't execute btrfs-fsck when I tried it as a replacement for ext4, it never completed, though I neglected to take note of the error messages.
Last note - I started up gparted (with the current latest setup) to test the integrity of the hard disc, both brief and extended disc tests showed no errors (pre-failure and old age on some rows, but that's to be expected, this machine is maybe 3-5 years old).
Any suggestions on what may be the problem, or any PEBKAC to point out? I eventually want to use this machine as console-only with VirtualBox running headlessly so I can rdesktop in to the Windows install (which will also be running 100% of the time, auto-started at boot), so I don't really need a DE or whatever. I'm just surprised to be having such problems, honestly.
EDIT: update - just got the problem on XFCE as well, but only AFTER installing virtualbox and qt (for virtualbox's GUI). Too much of a coincidence I think... uninstalled both, now going to stress test the machine with other apps for a while

The same thing is happening to me. I had just click on a form submit button and suddenly the video went dizzy for an very little instant, almost couldn't see it, the screen went black and a message warning the system crash appeared. After that, the system rebooted with a progress bar under the spinning circle and it turns my Mac off when it is fulfilled.
Trying the native Apple hardware test right now to see if it can identify any problem.
I'll post any news here in at most one hour, after the test finishes.

My Mavericks Partition Will Not Boot due to "Incorrect Number of Thread Records", But Windows 7 On Same Drive Does

I got up from my chair at the office to make myself coffee and came back to find my computer powered down. "That's weird," I said, "I don't remember turning the computer off." I pressed the power button and the loading bar appeared below he apple symbol (as it should do on a bad shutdown) but alas, when the bar got to the end, there was a loading ring, and the computer immediately shut down.
I then held down the alt key and was able to boot up in my Bootcamp Windows 7 partition (on the same hard drive) but I am unable to do a few things with my OS X Mavericks partition
First off I have the entire partition backed up, as I was able to access all of the files and the drive using my windows partition (drive appeared in "my computer" I was able to copy paste everything just fine). Secondly when I boot in the Recovery HD, the "Macintosh HD" partition appears unmounted, I can't erase it because disk utility says that the disk could not be opened. When I try to verify it, it says that the drive needs to be repaired, but when I repair it, disk utility tells me "Error: Disk utility can't repair this disk...disk, and restore your backed-up files."
tldr; I cannot erase the disk, I cannot repair the disk using disk utility in the Recovery HD, but I can see the disk in windows running on the same drive... so at least I have that going for me.
I tried starting up in verbose mode and it failed after 3 tries, I attempted to use the method described here http://african-heart.blogspot.com/2010/07/fixing-invalid-node-structure-in-mac.h tml?m=1 . I have run the method 6 times and nothing has worked. Ideally I'd like to wipe the "Macintosh HD" partition and start again, but I cannot seem to do that through disk utility
are there any methods for fixing the partition/wiping the partition that I am missing?

Datafile not restored due to missing or corrupt data

Hi all,
I was asked to restore a RMAN backup which we got from another region, the rman backup contains controlfiles and datafiles as compressed backupset.
oracle version is 10.2.0.3.0
aix version 6
First, I have restored the control file using the below command:
run
+{+
allocate channel t1 type disk;
restore controlfile from '/oracle/app/prod/rman/cf_t799873684_s17_p1';
alter database mount;
+}+
Second, I have cataloged the backup piece:
catalog backuppiece '/oracle/app/prod/rman/df_t794754324_s12_p1';
catalog backuppiece '/oracle/app/prod/rman/df_t793567544_s13_p1';
catalog backuppiece '/oracle/app/prod/rman/df_t731097654_s14_p1';

catalog backuppiece '/oracle/app/prod/rman/df_t792183472_s16_p1';
catalog backuppiece '/oracle/app/prod/rman/cf_t799873684_s17_p1';
Third, used below command to restore:
+run {+
allocate channel t1 type disk;
allocate channel t2 type disk;
allocate channel t3 type disk;
allocate channel t4 type disk;
set newname for datafile 01 to '/oracle/app/oradata/dbprod/system01.dbf';

set newname for datafile 20 to '/oracle/app/oradata/dbprod/indfile011.dbf';
restore database;
switch datafile all;
recover database;
+}+
But while restoring, I got error like below:

Bootcamp Partition Will Not Mount - Size Bootcamp Partition Will Not Mount - Also Size Discrepancies

I have bootcamp installed on an internal hard drive in my Mac Pro running 10.8.5. This HD had two partitions, one of which I had 200GB allocated for my Windows install. I reached a point where I was at nearly 100% capacity on that drive and needed more room. This is what I did:
Used Disk Utility to shrink the Mac OS Extended partition.
Erased free space on that partition.
Booted back into Windows and used MiniTool to extend the bootcamp partition to unallocated space.
MinoTool then performed a restart and finished it's job upon startup.
I am still able to boot into Windows and Mac just fine and I did create a backup of each OS before starting.
I have two issues now, however. Parallels no long recognized that Bootcamp partition. I decided to delete that VM and I had to uninstall Parallels completely anyways due to an upgrage isse to Parallels 9. After upgrading, Creating a VM from my BC was not an option. This is because the BC partition will not mount, it is greyed out in Disk Utitlity.
I tried installing Tuxera NTFS and the disk still cannot be mounted.
The other issue is that Disk Utility does not show the Bootcamp partition with the correct size. It still shows it with the original 200GB but does show that the Mac Partition was shrunk. In Windows, however, either using MiniTool or Windows Disk Managment, it shows the correct sizes for the partitions.
I'll attach a screenshot of DU.
I would like to be able to mount the drive successfully so that I can use the partition once again for Parallels.
This is the system.log display when attempting to mount the BOOTCAMP partition and when disabling Tuxera from the system preferences:

Josh,
I will defer to Christopher on correcting the GPT, but I agree it is incorrect. On a much simpler, single disk Macmini with Bootcamp...

/home partition corrupts randomly

My /home partition 'forgets' that it's ext4 every few restarts. Arch claims it's inconsistent when it tries to read it as an ext2 filesystem.
When I boot up gparted, it says the partition is unallocated.
Does anyone have any idea what's going on? Is my disk going bad? None of my other partitions/OSes have shown any signs of failing.

Partition table entries are not in disk order
As irrelevant as this info might be: sda1 is my boot, sda3 is Windows, and sda5 is Ubuntu.
My home partition corrupted 3 times today, and my data partition corrupted once. I would 'fix' them by reformatting them (this is a fresh install of Arch, so I didn't lose anything in either partition)
Both of them are now working now. Is there a log file I can post that would be more helpful to getting to the bottom of this issue?

To partition or not to partition: that is the question

I bought an external hard drive (1 TB) that I plan to use to back up my MacBook Pro by activating Time Machine. I also plan to use this new drive to back up 2 other external drives: a 150 GB drive with all my photos and a 500 GB drive with iMovies. So I guess there are 2 questions: 1) Is this a really dumb idea ?, 2) Does it matter whether or not I partition the new drive to separate my TM backed up Mac Book Pro, the 150GB photo drive, and the 500GB movie drive ? If I do not partition the new drive and activate TM, does TM then back up all 3 ? Is that a bad thing ? I read the FAQ but lack enough computer savvy to completely understand it. Thanks for your help.

It's not a dumb idea. However, a TM backup drive should have at least twice the capacity of all the devices it backs up. If you plan to backup 150 GB and 500 GB drives plus your MBP's drive then your backup drive is too small. My guess is you need a minimum of 2 TBs just to backup your computer's drive and the 500 GB iMovies drive. You then need an additional 300 GBs for the 150 GB hard drive.
It does not matter whether you partition the drive. TM stores the backups of each drive separately. Partitioning may provide a little degree of safety in that corruption of one partition will not result in being unable to access the other partitions.
Now that said a better approach is to backup each drive to its own separate backup drive. This requires three drives - one for the computer, one for iMovies, and one for photos. The only drawback is that TM on a single computer cannot automatically backup to three separate drives. At each backup you would have to reconfigure TM prefs to use a different drive.
Another option is to replace the 1 TB drive with two 2 or 3 TB drives arranged as a mirrored RAID. This provides backup as well as redundancy protection against drive failure. This is my preferred option for backup.

Can't install windows it says the boot camp partition is not formatted as a NTFS file structure

Using boot camp assistant it gets to the point of installing windows 7 and it won't because the boot camp partition is not a NTFS file structure. It also seems strange to me that there are 5 partitions would have expect ether 2 or 3. Please help this is very frustrating.
Thanks in advance

Open, if not so already, the Windows formatter. Identify the BC Windows partition. It will be the one listed with the proper size you created and/or will be labeled as a C: drive. Be careful you select the right one or you may be corrupting the entire drive.
Format the partition as NTFS.

[solved] crypttab partitions will not mount without "ASK"

I have three LUKS partitions on a hard drive (root, home, and swap) where the second two are controlled through /etc/crypttab. Boot fails on fsck because the home partition has not been mounted; if I change the crypttab entry from the password to "ASK" I am prompted for the password prior to fsck and the system boots fine. I obviously don't want to have to enter three passwords on boot, so I want the correct entries in crypttab.
What am I doing incorrectly?

I do not have any extra hard disks and the partition is in use, so I just reformatted my swap partition as a test with a simple "password", which worked flawlessly. So the problem is obviously the characters in the password. Thanks your help.
After further manual investigation (running read_crypttab from rc.sysinit) it appears that passwords cannot contain hash marks or the remaining part of the line is considered a comment - I think this is due to the use of eval in read_crypttab - and bash complains about an unexpected EOF due to a missing matching double quote. That is
swap /dev/sda2 "password#hash"
is evalled as
swap /dev/sda2 "password
which obviously can't work. But the double-quotes should take care of this; the top of the crypttab file says "to use special characters, surround it by quotes, the usual bash quoting rules apply".
And wouldn't you know it - I found a corresponding bug report. And the patch does fix the issue. Wonder why this hasn't been fixed yet...

ORA-19612: datafile 0 not restored due to missing data

Hello,
I'm testing a restore of the controlfile. The database is in archivelog mode and autobackup is set to ON. I successfully did a full backup and backup as copy database.
To test I did the following:
- note the DBID
- shutdown the database
- renamed both controlfiles:
$ mv /u02/rcat/control01.ctl /u02/rcat/control01.ctl_old
$ mv /u02/fra/rcat/control02.ctl /u02/fra/rcat/control02.ctl_old
When I try to restore the controlfile form autobackup I receive the following error. What could be reason please?

I used my Ipod while at the gym one day and now it's acting wacky. I have tunes that will not download due to an "unexpected error (-50). Anyone know what this is and how to fix it?

looks like the gtk theme is not the problem. didnt really think it was, but the documentation was worth posting. the guys over at ubuntu look as though they have dealt with this in great detail, and have produced a few solutions, which may or may not work. i have decided to post these for anyone else who may have these problems.
Solution 1 - new user creation:
https://bugs.launchpad.net/ubuntu/+bug/104521
Solution 2 - config file delete:
http://ge.ubuntuforums.com/showthread.php?t=724439
post number 6 here features the config file delete solution, as well as a link to another post which may be useful.
judging by a google search on this problem and the number of responses that came up, the bonobo/daemon error is quite a common curse for the users of gnome, although much more common in distros such as ubuntu or fedora.
i hope that this proves useful and if anyone has anything to add, please feel free. the more documentation the better.
EDIT:
another solution would be to remove gnome and reinstall it from scratch. (some please tell me if i am doing this correctly. thanks )
1. clean your catch:
pacman -Scc
2. remove gnome, gnome extras, and whatever other gnome files you might have installed
pacman -Rscn gnome gnome-extra etc...
3. reinstall gnome and gnome extras
pacman -Sy gnome gnome-extra
4. reconfigure your desktop the way you want.

Disk utility showing recover partition but not main partition

I have a Macbook Pro A1278 that has been dropped. I pulled the hard drive and ran seatools on it to verify it has no physical defects. The disk utility shows the recovery partition but not the main partition. It infrequently will boot to the users partition. I usually get the flashing folder with a question mark in it. What is the next step to try to backup the data on the drive and reinstall OS X.

Did you do this from the Recovery mode (either Recovery mode, internet or local)
Yes or No

One of my partition is not mounted. I can't mount it, can't repair it. I have a lot of data in this partition. I can't erase it, how can I do now? pls help me.

No way around this. Your phone has to be restored using a computer running iTunes. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

Application is not working due to memory issue

Hi Friesnds,
Kindly help me regarding settings in java. Scenario is like that. I have one server having two jboss versions (jboss-4.2.3 GA and jboss- 3.2.6). Each having java memory (JVM settings) 1 GB. The total memory of that server is 3 GB.
Problem is that every two days my application is not working due to memory issue. Once i freed the memory (through run the commands - (1). sync
(2). echo 3 > /proc/sys/vm/drop_caches
Application works fine.
I heared that the above command (echo 3 > /proc/sys/vm/drop_caches) can't run frequently because of server crash.
Kindly help me regarding this issue and provide the resolution.
Let me know if you need more information from my side.
Thanks

All of the above. I tested on 4 different networks and had no luck, I also had friends test my network and the other networks with their iPhones and all had no issues using FaceTime.
Also after I wiped my phone (erased all content and settings) I was able to successfully initiate a FaceTime call with no changes to my network and was also able to initiate another call when connected to another previously tested network that didn't work before. Once I restored from backup though, FaceTime stopped working again.
I did find this discussion: https://discussions.apple.com/thread/5163024?start=0&tstart=0
and tried the suggestions found there too. That discussion describes my issue I am having as well.

Charge the phone for 15 minutes with the Apple charger. Then hold the HOME and SLEEP buttons at the same time until an Apple logo appears.
